2. Introduction
2-1. General Information
Thank you for purchasing the TPH Series three phase Inverter/Charger.
TPH Series Pure Sine Wave Inverter is a combination of an inverter, charger, solar power and Auto-transfer
switch into one complete system. It is packed with unique features and it is one of the most advanced
inverter/chargers in the market today.
There are two main voltage outputs: 120/208Vac for America, 230/400Vac for Europe.
The inverter features an AC pass-through circuit, powering your home appliances from utility or generator
power while charging the battery. When utility power fails, the battery backup system keeps your appliances
powered until utility power is restored. Internal protection circuits prevent over-discharge of the batteries by
shutting down the inverter when a low battery condition occurs. When utility or generator power is restored,
the inverter transfers to the AC source and recharges the batteries.
Accessories allow the TPH series to also serve as a central hub of a renewable energy system. Set the TPH
Series inverter to battery priority mode, designates the inverter-preferred UPS configuration. In this
configuration, the load power in normally provided by the inverter. However, if the inverter output is
interrupted, an internal transfer switch automatically transfers the load from the inverter to commercial AC
power. The transfer time between inverter and line is short(8ms typical), and such transfers are normally not
detected by even highly sensitive loads. Upon restoration of inverter power, the inverter will transfer back to
inverter power.
On the line priority mode, when utility AC power cuts off(or falls out of acceptable range), the transfer relay
is de-energized and the load is automatically transferred to the Inverter output. Once the qualified AC utility
is restored, the relay is energized and the load is automatically reconnected to AC utility.
It features power factor corrected, sophisticated multi-stage charging and pure sine wave output with
unprecedentedly high surge capability to meet demanding power needs of inductive loads without
endangering the equipment.
TPH Series Inverter is equipped with a powerful charger. The overload capacity is 300% of continuous
output for up to 20 seconds to reliably support tools and equipment longer
Another important feature is that the inverter can be easily customized to Battery priority via a DIP switch,
this helps to extract maximum power from battery in renewable energy systems. Thus, the TPH-PV Series
Pure Sine Wave Inverter is suitable for Renewable energy system, Utility, RV, Marine and Emergency
appliances.
To get the most out of the power inverter, it must be installed, used and maintained properly. Please read the
instructions in this manual before installing and operating.

2.5.1 Inverter
Topology
The TPH inverter/charger is built according to the following topology.
Inverter: Full Bridge Topology.
AC Charger: Isolate Boost Topology
Solar Charger: MPPT PV Controller
Because of high efficiency IGBT and 32bit, 30MHz microprocessor and heavy transformers, it outputs
PURE SINE WAVE Waveform with an average THD of 3% (Max 8%) depending of load connected and
battery voltage.
The peak efficiency of TPH-PV series is 88%.
Overload Capacity
The TPH series inverters have different overload capacities, making it ideal to handle demanding loads.
1 For 110%<Load<125%(±10%), no audible alarm in 14 minutes, beeps 0.5s every 1s in the 15th minute,
and Fault(Turn off) after the 15th minute.
2 For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after the 1 minute.

- 8 -
3 For 300%≧Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.
2.5.2 AC Charger
TPH Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The PFC
feature is used to control the amount of power used to charge the batteries in order to obtain a power factor
as close as possible to 1.
Unlike other inverters whose max charging current decreases according to the input AC voltage, TPH-PV
series charger is able to output max current as long as input AC voltage is in the range of 164-243VAC
(95-127VAC for 120V model), and AC freq is in the range of 48-54Hz(58-64Hz for 60Hz model).
The TPH-PV series inverter is with a strong charging current of 120Amp (for 4KW,12V), and the max
charge current can be adjusted from 0%-100% via a linear switch at the right of the battery type selector.
This will be helpful if you are using our powerful charger on a small capacity battery bank. Fortunately, the
linear switch can effectively reduce the max charging current to 20% of its peak.
Choosing “0” in the battery type selector will disable charging function.
There are mainly 3 stages:
Bulk Charging: This is the initial stage of charging. While Bulk Charging, the charger supplies the battery
with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage
(determined by the Battery Type selection) is achieved.
Software timer will measure the time fromA/C start until the battery charger reaches 0.3V below the boost
voltage, then take this time asT0 and T0×2 = T1.
Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached.
Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order
to maintain the absorb voltage setting.
In this period, the inverter will start a T1 timer; the charger will keep the boost voltage in Boost CV mode
until the T1 timer has run out. Then drop the voltage down to the float voltage. The timer has a minimum
time of 1 hour and a maximum time of 12 hours.
Float Charging: The third charging stage occurs at the end of the Absorb Charging time. While Float
charging, the charge voltage is reduced to the fl oat charge voltage (determined by the Battery Type
selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter.
If theA/C is reconnected or the battery voltage drops below 12Vdc/24Vdc/48Vdc, the charger will reset the
cycle above.
If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the
battery. Table 2.5.1 Battery Charging Processes

De-sulphation
The de-sulphation cycle on switch position 8 is marked in red because this is a very dangerous setting if you
do not know what you are doing. Before ever attempting to use this cycle you must clearly understand what
it does and when and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries(nor), or if the batteries have
been left discharged so low that they will not accept a charge. This cycle is a very high voltage charge cycle
designed to try to break down the sulfated crust that is preventing the plates taking a charge and thus allow
the plates to clean up and so accept charge once again.
Charging depleted batteries
The TPH series inverter allows start up and through power with depleted batteries.
For 12VDC model, after the battery voltage goes below 10V, if the switch is still (and always) kept in "ON"
position, the inverter is always connected with battery, and the battery voltage does not drop below 2V, the
inverter will be able to charge the battery once qualified AC inputs are present.
Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to
“Off”, then to “ON”.
When the voltage goes below 9VDC, and you accidently turn the switch to OFF or disconnect the inverter
from battery, the inverter will not be able to charge the battery once again, because the CPU loses memory
during this process.

The charging capacity will go to peak in around 3 seconds. This may cause a generator to drop frequency,
making inverter transfer to battery mode.
It is suggested to gradually put charging load on the generator by switching the charging switch from min to
max, together with the 15s switch delay, our inverter gives the generator enough time to spin up. This will
depend on the size of the generator and rate of charge.
2.5.3 Transfer
While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the
VAC Trip voltage (154 VAC, default setting for 230VAC,90VAC for 120VAC), the inverter automatically
transfers back to the Inverter Mode with minimum interruption to your appliances - as long as the inverter is
turned on. The transfer from Standby mode to Inverter mode occurs in approximately 8 milliseconds.And it
is the same time from Inverter mode to Standby mode.
Though it is not designed as a computer UPS system, this transfer time is usually fast enough to keep your
equipment powered up.
There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the
input terminals to when the transfer is made. This delay is built in to provide time for a generator to spin-up
to a stable voltage and avoid relay chattering. The inverter will not transfer to generator until it has locked
onto the generator’s output. This delay is also designed to avoid frequent switching when input utility is
unstable.
The transfer time from DC to AC is 0ms.
The transfer time from AC to DC is typically 6-8ms, 10ms max.
2.5.4 Frequency adjust
The frequency of the inverter is arranged by the SW4. Refer to the Table 2.5.11.
The factory default configuration for 220/230/240VAC inverter is 50Hz, and 60Hz for 100/110/120VAC
inverter. While the output freq can be easily changed once a qualified freq is applied to the inverter.
2.5.5 Power Saver Mode
There are 3 different working status for TPH inverter: “Power Saver Auto” 、“Power Saver Off” and
“Power Off”.
When power switch is in “Unit Off” position, the inverter is powered off.
When power switch is turned to either of “Power Saver Auto” or “Power Saver Off”, the inverter is powered
on.Power saver function is designed to conserve battery power when AC power is not or rarely required by
the loads.
In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical appliance). Whenever
an AC load (greater than 25 watts) is turned on, the inverter recognizes the need for power and automatically

starts inverting and output goes to full voltage. When there is no load (or less than 25 watts) detected, the
inverter automatically goes back into search mode to minimize energy consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensing moments, thus the idle
consumption is significantly reduced.

When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound.
At full output voltage, the green power LED will light steadily and the inverter will make a steady humming
sound. When the inverter is used as an “Un-interruptible power supply” the search sense mode or “Power
Saver On” function should be defeated.
Exceptions
Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights are the most
common example. (Try altering the plug polarity by turning the plug over.) Some computers and
sophisticated electronics have power supplies that do not present a load until line voltage is available. When
this occurs, each unit waits for the other to begin. To drive these loads either a small companion load must

be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full
output voltage.
2.5.6 Protections
The TPH series inverter is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1sec after fault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to
restart the inverter.
The Low batter voltage trip point can be customized from defaulted value 10VDC to 10.5VDC turn the SW1
on DIP switch.
The inverter will go to Over temp protection when heat sink temp. ≥105ºC, and go to Fault (shutdown
Output) after 30 seconds. The switch has to be reset to activate the inverter.
The TPH series Inverter has back feeding protection which avoids presenting an AC voltage on the AC input
terminal in Invert mode.
After the reason for fault is cleared, the inverter has to be reset to start working.
2.5.7 Remote control Module
Apart from the switch panel on the front of the inverter, an extra switch panel connected to the RJ11 port at
the DC side of the inverter thru a standard telephone cable can also control the operation of the inverter.
If an extra switch panel is connected to the inverter via “remote control port”, together with the panel on the
inverter case, the two panels will be connected and operated in parallel.
Whichever first switches from “Off” to “Power saver off” or “Power saver on”, it will power the inverter on.
If the commands from the two panels conflict, the inverter will accept command according to the following
priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to “Unit Off” position will the inverter be powered off.
The Max length of the cable is 10 meters.
WARNING

- 13 -
Never cut the telephone cable when the cable is attached to inverter and battery is connected to the inverter.
Even if the inverter is turned off. It will damage the remote PCB inside if the cable is short circuited during
cutting.

2.5.10 FAN Operation
For 1-3KW, there is one multiple controlled DC fan，For 4-6KW, there is two multiple controlled DC fan
which starts to work according to the following logic
For 8-12KW, there is two multiple controlled DC fan and one AC fan. The DC fan will work in the same
way as the one on 1-3KW, while the AC fan will work once there is AC output from the inverter.
So when the inverter is in power saver mode, the AC fan will work from time to time in response to the
pulse sent by the inverter in power saver mode.
The Operation of the DC fan at the DC terminal side is controlled by the following logic

Allow at least 30cm of clearance around the inverter for air flow. Make sure that the air can circulate freely
around the unit.
Variable speed fan operation is required in inverter and charge mode. This is to be implemented in such a
way as to ensure high reliability and safe unit and component operating temperatures in an operating
ambient temperature up to 50°C.
Speed to be controlled in a smooth manner as a function of internal temperature and/or current.
Fan should not start/stop suddenly.
Fan should run at minimum speed needed to cool unit.

For 12VDC model, the Low Battery Trip Volt is set at 10.0Vdc by typical deep cycle lead acid battery. It
can be customized to 10.5Vdc using SW1 for sealed car battery, this is to prevent batteries from
over-discharging while there is only a small load applied on the inverter.(*2 for 24VDC, *4 for 48VDC)
SW2: AC Input Range:
There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100-135V for
120VAC model) is required to protect them.
While for some resistive loads which work in a wide voltage range, the input AC range can be customized to
140-270VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power
without frequent switches to the battery bank.
In order to make the inverter accept dirty power from a generator, when the SW2 is switched to position“1” ,
the inverter will bypass an AC input with a wide voltage and frequency(40Hz-70Hz for 50Hz/60Hz).
Accordingly, the AC charger will also work in a wide voltage and frequency range (43Hz-67Hz for

50Hz/60Hz). This will avoid frequent switches between battery and generator. But some sensitive loads will
suffer from the low quality power.
The pros and cons should be clearly realized.
SW3: Power Saver Auto Setting :
In Power Saver Mode, when the SW3 is switched to position“0”, inverter will work in Unit Off Charging
mode, it will stay in standby mode without sensing loads. It won’t output any power even if a load is turned
on. The inverter will not perform any function and only stay idle in this mode. When a qualified AC input
present, it will switch to AC input power to charge the battery and supply the load at the same time.
When the SW3 is switched to position“0”, the inverter is initially in standby mode and sends a pulse to
detect the presence of a load every 3 seconds. Each pulse lasts for 250ms. The inverter will remain in
standby mode until a load has been detected. Then it will wake up from standby mode and start to inverter
electricity from the battery bank to supply the load.
SW4: Frequency Switch:
The output frequency of the inverter can be set at either 50Hz or 60Hz by SW4.
SW5: Solar Mode/AC Mode Priority:
Our inverter is designed with AC priority by default. This means, when AC input is present, the battery will
be charged first, and the inverter will transfer the input AC to power the load. Only when the AC input is
stable for a continuous period of 15 days, the inverter will start a battery inverting cycle to protect the
battery. After 1 normal charging cycle ac through put will be restored.
The AC Priority and Battery Priority switch is SW5. When you choose battery priority, the inverter will
inverting from battery despite the AC input. Only when the battery voltage is reaches low voltage alarm
point(10.5V for 12V), the inverter transfers to AC Input, charge battery, and switch back to battery when
battery is charged full. This function is mainly for wind/solar systems taking utility power as back up.
2.5.12 Other features
Battery voltage recovery start
After low battery voltage shut off (10V for 12V model/20V for 24V model/40V for 48V model), the inverter
is able to restore operation after the battery voltage recovers to 13Vdc/26Vdc/52Vdc (with power switch still
in the “On” position). This function helps to save the users extra labor to reactivate the inverter when the
low battery voltage returns to an acceptable range in the renewable energy systems. The built in battery
charger will automatically reactivate as soon as city/generator ac has been stable for 15 seconds.
WARNING
Never leave the loads unattended, some loads (like a Heater) may cause accident in such cases.
It is better to shut everything down after low voltage trip than to leave your load on, due to the risk of fire.
Auto Generator Start (AGS)
The inverter can be customized to start up a generator when battery voltage goes low.
When the inverter goes to low battery alarm, it can send a signal to start a generator, and turn the generator
off after battery charging is finished.

- 16 -
The auto generator start feature will only work with generators designed to work with this feature. There is
an open/closed relay that will short circuit the positive and negative cable from a generator. The input DC
voltage can vary, but the Max current the relay can carry is 16Amp.
Battery temperature sensor (BTS)
A battery temperature sensor (BTS) option can easily be installed in the system to ensure proper charging of
the batteries based on temperature. Installing a BTS extends battery life by preventing overcharging in warm
temperatures and undercharging in cold temperatures.
To install the Battery Temperature Sensor:
1. Run the battery temperature sensor wire in the DC conduit (if used) and route the RJ11 connector end to
the BATTERY SENSE port located on the front of the inverter.
2. Secure the sensor to one of the batteries located in the center of the battery pack.
Conformal Coating
Entire line of TPH inverters have been processed with a conformal coating on the PCB making it water, rust,
and dust resistant.

3-2 DC Wiring recommendation

- 17 -
It is suggested the battery bank be kept as close as possible to the inverter. The following able is a suggested
wiring option for 1m DC cable.
Please find the following minimum wire size. In case of DC cable longer than 1m, please increase the cross
section of cable to reduce the loss.
Please note that if there is a problem obtaining for example 100mm²cable, use 2*50mm²or 3*35mm².
One cable is always best , but cable is simply copper and all you require is the copper, so it does not matter
if it is one cable or 10 cables as long as the square area adds up. Performance of any product can be
improved by thicker cable and shorter runs, so if in doubt round up and keep the length as short as possible.
Battery cables must have crimped (or preferably, soldered and crimped) copper compression lugs unless
aluminum mechanical lugs are used. Soldered connections alone are not acceptable. High quality, UL-listed
battery cables are available .These cables are color-coded with pressure crimped, sealed ring terminals.

CAUTION: Equipment Damage
The inverter is not reverse polarity protected. Reversing the battery polarity on the DC input connections
will cause permanent damage to the inverter which is not covered under warranty. Always check polarity
before making connections to the inverter.
WARNING: Shock Hazard
Ensure the inverter is off before disconnecting the battery cables, and that AC power is disconnected from
the inverter input.
Battery terminal must be clean to reduce the resistance between the DC terminal and cable connection. A
buildup of dirt or oxidation may eventually lead to the cable terminal overheating during periods of high
current draw. Use a stiff wire brush and remove all dirt and corrosion from the battery terminals and cables.
3-3 AC Wiring
We recommend using 10-5AWG wire to connect to the AC terminal block.
The three phase inverter only supports Y connection. It willn’t support delta connection.
There are 3 different ways of connecting to the terminal block depending on the model. All the wirings are CE
compliant, Call our tech support if you are not sure about how to wire any part of your inverter.
The TPH inverter will automatically bond the neutral with ground in DC toAC battery mode, and separate neutral with
ground inAC model.
