PRODUCT DESCRIPTION
The Solar Boost 3000i is a Maximum Power Point Tracking (MPPT) solar charge controller able to charge 12V batteries at up to 30 amps from 36 cell
12V PV modules. Patented MPPT technology operates the modules electrically in a manner that harvests all available PV power and can increase
charge current up to 30% or more compared to conventional PWM type controllers. The voltage step-down operation of the MPPT power
converter also allows use higher voltage 60 cell grid-tie PV modules at up to 22 amps of output current producing a charge current increase
approaching 200% with 60 cell modules. The 3000i’s sophisticated and fully adjustable 3-stage plus equalization charge control system optimally
charges flooded, GEL and AGM lead-acid chemistry batteries. Electronic protection is provided against voltage transients, over temperature, over
current, short circuit, swapped battery & PV, and reverse battery & PV polarity. A very low power LED display is provided to monitor PV charge
performance and includes a resettable amp-hour counter which computes total PV amp-hours produced. A user configurable auxiliary output is also
provided which can serve as either a 20 amp LVD load controller, a 20 amp lighting controller with LVD, or a 2 amp auxiliary battery charger for a
second battery such as the engine start battery in an RV. To allow easy system expandability the 3000i may also operate as an IPN Network Master
controlling up to 7 Blue Sky Energy IPN compatible charge controllers such as the SB3024iL. Blue Sky Energy’s IPN Network allows multiple charge
controllers to communicate with each other and coordinate their activities to charge the battery as a single coordinated charging machine.

OPERATION
Basic charge control operations are fully automatic and require no operator intervention. When sufficient PV power is available the 3000i will
switch to a Charge ON state and begin charging the battery. The particular charge mode the 3000i will operate in will vary depending on the needs
of the battery and available PV charge current. When insufficient PV current is available to charge the battery the 3000i will switch to a Charge Off
state and the PV array will be disconnected from the battery to prevent unwanted current drain. There is a 5 second turn-on delay, and a 45 second
turn-off delay.
➢The 3000i operates on battery power, not PV power. Insure that voltage on the battery terminals of the 3000i is
always the same as actual battery voltage within a few 10ths of a volt and greater than 9 volts for proper
operation. Note that the front panel serves as a heatsink for power control devices and may become quite warm
during normal operation.
➢CAUTION: Do not disconnect the battery while the 3000i is in a Charge ON state. A healthy battery is a key
component of the charge voltage control system and provides charge voltage filtering. Sudden removal of the battery
while the 3000i is charging will produce voltage spikes at the 3000i’s battery terminals which may damage 12 volt
appliances still connected to the 3000i, especially when using higher voltage 60 cell PV modules.
IF THE BATTERY MUST BE DISCONNECTED, REMOVE PV POWER FIRST.
CHARGE STATUS INDICATION
Present charge status of the 3000i is indicated using two charge status LED’s, Absorption & Float. If net battery charge current is greater than about 3 to
5 amps per 100 amp-hours of battery capacity the charge status indicator can provide a rough indication of battery state of charge.

DIGITAL DISPLAY
When the 3000i completes self-test the VOLT/AMP display mode is active. This mode displays Battery Voltage continuously if the 3000i is in a Charge Off
state, or alternates between Battery Voltage & Output Charge Current if the 3000i is charging the battery. The AMPS indicator in the upper left of the
display will be on solid when displaying 3000i output current, or blinking when displaying PV input current. To provide good readability yet minimize
the likelihood of the display being objectionably bright at night an automatic night time dimming feature dims the display at night when the 3000i is
in a Charge Off state. Other display modes may be selected using the Display Select push-button. Each brief press of Display Select selects the next
display mode as shown on the front panel graphic of Figure 1. VOLT shows Battery Voltage, AMP-OUT shows 3000i Output Charge Current, AMP-IN
shows PV Input Current, and AMP-HRS shows total PV Amp-Hours produced since the amp-hour counter was last cleared. If the 3000i is part of a multi-

controller system using the IPN Network the 3000i’s display will show the total of all controllers on the network. AUX-VOLT shows voltage on 3000i’s the
auxiliary output. When the auxiliary output is configured for Auxiliary Battery Charge (factory default) and the 2 amp auxiliary charge output is
connected to an auxiliary battery (such as the engine start battery in a Motorhome) the voltage of the auxiliary battery is displayed. If the auxiliary
output is configured for Load Control, the voltage displayed is that applied to the load.
SOLAR CHARGE AMP-HOUR COUNTER
The battery essentially serves as a “storage tank”, with the battery storing electrical energy in units referred to as amp-hours. Amp-hours are
computed by multiplying current in amps X time in hours. For example 20 amp-hours may be a current of 10 amps flowing for 2 hours, or may be 1
amp flowing for 20 hours. The battery receives and stores amp-hours when being charged, and then delivers those stored amp-hours when being
discharged. The amp-hour counter displays total solar charge amp-hours accumulated since the last time the counter was cleared up to a maximum
count of 999 amp-hours. Amp-hour production varies widely with operating conditions, but as a very broad brush approximation 100 watts of PV
modules can deliver up to a maximum of about 30 amp-hours per day. Any partial shading, lower sun intensity, shorter days, or time spent in
Absorption or Float will decrease amp-hours produced. The present amp-hour count may be cleared by pressing Display Select for 5 seconds while
viewing amp-hours on the display.
BATTERY LEVEL GRAPHIC
The 3000i provides a battery level graphic on the front panel which indicates approximate battery level versus battery voltage. Generally a higher voltage
is better than a lower voltage. A battery that is being charged will typically range in voltage from about 12.5 volts after charge commences, to 14.0 volts
or greater when the battery is highly charged. Once charge stops and the battery begins discharging and delivering power to a load it is normal for
battery voltage to drop. A battery under a light load of about 1 amp per 100 amp-hours of battery capacity may range between about 12.5 volts when
the battery is full, down to perhaps 12.0 volts when the battery is about 50% discharged. Battery voltage during discharge will tend to be higher under
light load and lower under a heavier load.
Do not think of these voltage values as absolutes but rather as a broad brush indication of approximate battery charge level. Voltage at a particular state
of charge will vary with battery size, age, construction, temperature, and with the level of charge or discharge current. Most battery manufacturers
recommend not discharging below about 50% DOD (depth of discharge) to promote improved battery performance and life. Avoid allowing battery
voltage to drop below about 11.5 volts, and NEVER allow battery voltage to drop below 10.0 volts. If a highly accurate battery charge level indication is
desired, consider installing an optional IPN ProRemote display.
FRONT PANEL OPERATION & INDICATORS
FIGURE 1
3-STAGE CHARGE CONTROL
The 3000i is factory configured for a 3-stage charging process, Bulk, Absorption and Float, which is fully automatic and requires no operator
intervention. The 3-stage charge process applies a somewhat higher Absorption charge voltage to charge the battery quickly and safely. Once the
battery is fully charged a somewhat lower Float voltage is applied to maintain the battery in a fully charged state without excessive water loss.
➢The charge control system always starts in Absorption and will return to Absorption upon exiting Current Limit
or Equalization. Following a 10 second delay in Absorption the 3000i may move on to other charge modes based
on battery and system needs.
Bulk Charge
The 3000i will switch to Bulk charge when battery voltage remains below the present Charge Voltage setpoint. During Bulk the 3000i delivers as
much charge current as possible to rapidly recharge the battery. During Bulk it is a combination of battery size, state of charge and available
charge current that determine battery voltage, not the 3000i.

Absorption Charge
Once the battery recovers sufficient charge for battery voltage to rise to the Absorption Charge Voltage setpoint (factory set to 14.4V), charge
current is reduced as necessary to hold the battery at the Absorption Voltage. The 3000i will return to Bulk should battery voltage remain below
the Absorption Voltage setpoint for more than 10 seconds. The 3000i remains in Absorption until the battery is fully charged as determined by
either;
1) The 3000i remains continuously in Absorption for the Absorption Charge Time period (factory set to 2 hours).
OR 
2) With the optional IPN ProRemote display and battery system monitor, net battery charge current decreases to the Float Transition
Current (factory set in the ProRemote to 1.5 amps per 100 amp-hours of battery capacity).
Float Charge
Once the battery is fully charged a somewhat lower Float Voltage (factory set to 13.2V) is applied to maintain the battery in a fully charged
state without excessive water loss. The 3000i will return to Absorption should battery voltage remain below the Float Voltage setpoint for
more than 10 seconds.
2-STAGE CHARGE CONTROL
The 3000i may be configured for 2-stage charge control if desired by setting the Float Charge Voltage setting to “OFF” (NO Float).
OUTPUT CURRENT LIMIT
Should conditions be present where the PV modules are able to produce more than 30 amps of output current with 36 cell PV modules, or 22 amps
with 60 cell PV modules, the 3000i will automatically limit output current to this value. Note that when current drops and the 3000i exits current
limit it will first enter Absorption on its way back to Bulk even though battery voltage may be below the Absorption Charge Voltage setpoint.
➢WARNING: Current limit should be thought of as transient PV over current protection and not a normal mode
of operation. If the 3000i enters 30 amp or 22 amp current limit on a regular basis it is possible that excessive PV
power is connected. Confirm that the PV modules do not exceed ratings shown in the Selecting PV Modules
section.
OPTIONAL TEMPERATURE COMPENSATION
The charge voltage required by batteries changes with battery temperature. Temperature compensation of charge voltage enhances battery
performance and life while decreasing battery maintenance. Temperature compensation of charge voltage can be provided using the optional
battery temperature sensor (BSE p/n 930-0022-20). The default compensation factor of –30mV/C (–5.00mV/C/cell) is typically appropriate for
most lead-acid chemistry batteries including GEL and AGM. If a proper temperature sensor signal is not detected the 3000i will operate as if battery
temperature is 25C.
FACTORY DEFAULT CHARGE VOLTAGE SETPOINTS -VS.- BATTERY TEMPERATURE
FIGURE 2
EQUALIZATION
➢WARNING: Not all batteries can be safely equalized. Equalization should be performed only on vented liquid
electrolyte lead-acid batteries. Always follow battery manufacturers recommendations pertaining to equalization.
Equalization applies a relatively high charge voltage producing significant battery gassing. Prior to performing
equalization disconnect equipment that cannot tolerate the high equalization voltage which is temperature
compensated as shown above.
Equalization is a controlled overcharge used to bring all battery cells up to the same specific gravity and state of charge. The 3000i may be configured to
perform an automatic equalization on periodic basis, or a manual equalization. Since sealed batteries should not be equalized the factory default
settings have Equalize Enable (EqE) set to OFF to disable automatic or manual equalization. Equalization may be enabled by setting Equalize Enable to
ON as described in the Charge And Load Control Settings section. When an equalization cycle is being performed the Float and Absorption charge status

Installation and Operation Manual
Blue Sky Energy | USA | www.blueskyenergyinc.com 6
LED’s will alternately blink. With equalize enabled the 3000i will perform an automatic equalization at the factory default settings of 15.2V for 2 hours
every 30 days which is typically suitable for most flooded lead-acid batteries. When set for automatic equalization the cycle will begin when the set
number of days since the last equalization has elapsed, and the charge control system has switched to Float. When set for manual equalization (Eqd set
to 00) an automatic equalization will not occur. Whether set for automatic or manual the process may be started or stopped manually by pressing the
Display Select push-button for 20 seconds. Once equalization has started the equalize timer will not count down unless battery voltage is at the equalize
voltage setpoint which is temperature compensated as shown above. Therefore obtaining a proper 2 hour equalization will require longer than 2 hours
to complete depending on available charge current. Note that at least 3.5 amps of net charge current per 100 amp-hours of battery capacity is typically
required to properly equalize a battery. If equalization does not complete during the charging day it will resume where it left off the next charging day,
but will automatically cancel if unable to complete within 24 hours. The equalize day counter is reset whenever an equalization cycle is started.
MAXIMUM SETPOINT VOLTAGE LIMIT
The maximum setpoint voltage limit places a maximum limit or ceiling on the charge voltage setpoint used by the 3000i in all charge modes to
prevent inverters or other equipment from shutting down due to excess voltage. Regardless of initial setpoints, charge mode or temperature
compensation the 3000i will not use a charge voltage setpoint greater than the maximum setpoint voltage limit (uPr) factory set to 15.5V. Note that
voltage may briefly exceed this value by 0.1 –0.2V as the system responds to sudden changes in load or PV power.
MAXIMUM POWER POINT TRACKING (MPPT)
The 3000i’s patented MPPT technology can increase charge current up to 30% or more compared to conventional PWM controllers operating 36
cell PV modules. Principal operating conditions affecting current boost performance are PV cell temperature and battery voltage, with lower PV
temperature and lower battery voltage producing greater charge current increase. In cool comfortable temperatures most systems see about 10 –20%
increase. Increase may go to zero in hot temperatures, whereas charge current increase may easily exceed 30% with a discharged battery and freezing
temperatures. MPPT also allows efficient use of higher voltage 60 cell modules by converting their much higher voltage down to battery voltage.
Ignoring conversion losses the conversion process produces an output current roughly equal to PV current times the ratio of PV voltage to battery
voltage. If a 60 cell module is operating at 25V with 5 amps of output, and battery voltage was 13V, output charge current from the 3000i would be
about 5 amps times 25V 13V or about 9.6 amps. For a more complete MPPT description see “What Is MPPT and how does it work?” on the FAQ page
at www.blueskyenergyinc.com.
PANEL TEMPERATURE AND THERMAL PROTECTION
Internal power control devices use the front panel as a heatsink. It is normal for the front panel to become quite warm to the touch when the 3000i
is operating normally. Front panel heating will be the greatest when the 3000i is processing either very high power or very low power. When
mounted to a vertical surface with good ventilation, the 3000i can deliver full output in an ambient temperature of up to 45C (113F). If an over
temperature condition exists, the 3000i will simply cycle on and off to keep internal temperature within acceptable limits.
MULTIPLE CHARGE CONTROLLERS ON THE IPN NETWORK
The 3000i may also operate as an IPN Network Master controlling up to 7 remote Blue Sky Energy IPN compatible charge controllers such as the
SB3024iL or SB2512iX-HV. The IPN Network allows multiple charge controllers to communicate with each other and coordinate their activities to
charge the battery as a single coordinated charging machine. The IPN Network allows an existing 3000i installation to be expanded greatly in power
handling capability by adding charge additional controllers and PV modules with all controllers displaying through the existing 3000i display.
➢When serving as an IPN network Master the 3000i’s display will show the sum of all controllers on the network
for input current, output current and solar charge amp-hours. If a remote Slave controller has good PV input but
the 3000i does not, the 3000i’s charge control system will properly direct the Slaves as indicated on the 3000i’s
Charge Status LED’s, but the 3000i’s display will be dim while the 3000i’s own power controller remains off. The
display will become bright once the 3000i receives good PV input.
INSTALLATION
➢WARNING: Read, understand and follow the Important Safety Instructions in the beginning of this manual before
proceeding. This unit must be installed and wired in accordance with National Electrical Code, ANSI/NFPA 70. Over
current protection must be provided externally. To reduce the risk of fire, connect to a circuit provided with 40 amp
maximum branch-circuit over current protection in accordance with National Electrical Code, ANSI/NFPA 70 with 36
cell modules, or 30 amp maximum with 60 cell modules. Do not connect a PV array capable of delivering greater
than 24 amps of short circuit current ISC at STC with 36 cell modules, or 11.8 amps with 60 cell modules. Do not
connect BAT–and PV–together external to the unit. To reduce risk of electric shock or product damage, remove all
sources of power before installing or servicing. Figures 4 and 5 show generalized connections only and are not
intended to show all wiring, circuit protection and safety requirements for a photovoltaic electrical system.
➢CAUTION: The 3000i is protected against reverse battery and PV polarity, and swapped PV and battery
connections, but will be damaged by reverse battery to the PV terminals. Transient voltage lightning protection is
provided, but steady state voltage in excess of 50VDC on the battery or PV terminals will damage the unit. Damage
of either type voids the limited warranty.
CHARGE AND LOAD CONTROL SETTINGS
The 3000i contains various charge control and load control settings all of which are preconfigured at the factory to the default settings shown
below. Most installations require no changes to these settings which are typically suitable for most flooded, GEL and AGM lead-acid chemistry
batteries. Check with your battery manufacturer to confirm that these settings are suitable for your particular battery.

present Absorption Charge Voltage setting is 14.4V.
A brief press of Setup within 5 seconds will move to the next setting shown in Table 2, Absorption Charge Time
where the display will now alternate between Abt and 2.0 to show the present Absorption Charge Time setting is
2.0 hours. Remaining settings may be viewed by repeatedly pressing Setup to move to the desired setting. To exit
Viewing Mode and return to normal operation, do not press Setup for 5 seconds.
Changing a setting
To enter the Changing Mode, first enter the Viewing Mode for the setting to be changed. While in Viewing Mode
for that setting, press Setup 5 seconds to enter the Changing Mode for that setting. The present setting value will
begin blinking rapidly indicating that you have entered the parameter changing mode for that setting. Use Display
Select to scroll through the available values until the desired value is reached. With the desired new value blinking
in the display press Setup 5 seconds to save the new setting. Once the new setting is saved the display will revert
back to the Viewing Mode showing the new saved value for that setting.
If neither Setup or Display Select is pressed within 5 seconds while in the Changing Mode, the change request is
abandoned and the display reverts back to Viewing Mode without changing the setting.

TABLE 2
SELECTING PV MODULES
The 3000i is designed to operate conventional 12V 36 cell PV modules or higher voltage 60 cell modules. It is not intended for use with 72 cell
modules. If multiple PV modules are used best MPPT current boost performance will be obtained if all PV modules are identical. Dissimilar modules
should have VMP values within 0.5V or better and be of the same basic cell technology so their VMP will tend to track as operating conditions
change. If module types are very different consider using a separate charge controller for each module type to obtain the best MPPT current boost
performance. When multiple controllers are used on the IPN Network each controller independently MPPT’s their modules to their best. Do not mix
36 cell and 60 cell modules on the same controller. Select PV modules that do not exceed the maximum ratings shown below, and preferably
produce IMP of at least 3.5 amps (2 amps with 60 cell modules) per 100 amp-hours of battery capacity.
Voltage, current and power produced by PV modules fluctuate widely with operating conditions. As a result a set of test conditions referred to as
Standard Test Conditions (STC)are used to rate modules in a meaningful manner and accurately predict real world performance. STC ratings are
not maximum or optimal ratings. Conditions can be present where VOC and ISC approach 1.25 times STC ratings which is why National Electrical Code
and our recommendations call for 1.25 derating of both VOC and ISC. Yet in real world conditions IMP actually seen is commonly only about 75 –80%
of IMP at STC.
Key PV module specifications;
PMAX Maximum power in watts (PMAX = VMP x IMP)
VOC Voltage with module open circuit (typically 20 –22V for 12V nominal 36 cell modules)
VMP Voltage where module produces Maximum Power (typically 17 –18V for 12V nominal 36 cell modules)
IMP Current where module produces Maximum Power
ISC Current with module Short Circuit

MOUNTING
➢CAUTION: The front panel may become quite warm to the touch during normal operation. Mount the 3000i
vertically to promote air flow and cooling, do not enclose in a confined space and avoid mounting in direct sunlight.
The 3000i is not watertight and must be protected from rain, snow and excessive moisture. Corrosion resulting from
liquid water or excessive moisture voids the limited warranty. An optional black powder coated deluxe mounting box
is available as BSE p/n 720-0011-01. The optional mounting box is the same X,Y dimension as the 3000i front panel
and 2.75” (7cm) deep.

BATTERY AND PV WIRING
A desirable installation will produce a total system wiring voltage drop of 3% or less. The lengths shown in Table 3 are one way from the PV modules to
the battery with the 3000i located along the path. Length can be increased inversely proportional to actual PV IMP such that if current was reduced by 1/2
wire lengths could be doubled and still provide the same 3% voltage drop. For 60 cell modules use two wire sizes larger than shown (e.g., 8awg rather
than 12awg) for the wire section between the 3000i and the battery.

➢CAUTION: Battery and PV compression terminals accept #16 #8 AWG wire and are to be tightened to 15.9 in-
lb (1.80 nm). Temperature Sensor and IPN Network compression terminals accept #2616 AWG wire and are to
be tightened to 2.1 in-lb (0.24 nm). Take care to route wires in a manner that does not place undue strain on the
3000i’s compression terminal blocks.
