INSTALLATION & OPERATION SURYA-40 HV VERS.7
1) PV Panel Grouping: Group the PV panel array using standard Solar MC4 connectors and parallel
connectors as to the recommended grouping example chart provided. Good quality weather proof solar DC
cables must be used (4sq,6sq,10sq).
2) Battery Bank Setup: If more than one battery is used, Connect the batteries with 16sq.mm/10 sq.mm
interlinking cables and tight them well. Check each battery separately for specific gravity, same terminal volt
and good backup.Do not use old and new batteries together, either in parallel or in series
3) MPPT Charge controller installation: Mount the MPPT charge controller vertically on the wall using
the wall mounting clamp provided. It is better to isolate MPPT from the wall , mounting it on a PVC board
(kitchen cutting board) in order to avoid lightning hazards and earth leakage problems.
❎ Avoid exposure to rain, dusty area, direct sun light or in area having high temperature
✅ Use 25 sq.mm/16 Sq.mm standard electric cables below 1.5 metre length as battery wires, red colour for
positive connection and black for negative. Remove the connection terminal cover of the charger.and
connect the battery wires with correct polarity to the desired battery bank (Reverse polarity will spoil the
charge controller)
Three LED Indicators and cooling fan of the device starts functioning for 5 seconds and goes o.
MPPT starts scanning connected battery bank.Display shows the voltage of the connected battery bank and
applicable range of PV Panel Open Circuit Voltage (Voc) limit for the connected battery bank.Ensure the
displayed battery bank voltage and connected battery bank voltage is same when MPPT is powered on.

Connect the cables from PV panels to the solar positive and negative terminals of the charge controller. If the
panel voltage and polarity is correct green LED indicator glows on. When the PV Panel voltage detected is
higher than the connected battery bank voltage MPPT starts charging.
When the PV panel voltage goes below the battery bank voltage the green LED indicator goes o.When the
device detects more than 2Amp charging current to the battery, charging LED (RED) glows on.
If the current is less than 2Amp the Red LED goes o ,but charging continuous in low amp till the solar power
availability.
When the connected battery voltage reaches 14.2V (adjustable) the Blue LED glows on indicating battery is
near full charge (default value 14.2V) and ready to use load either directly from the battery or through an
inverter.
How MPPT charger controls the connected Inverter:
Charge controller is provided with a relay inside to connect and disconnect grid power to inverter monitoring
the terminal volt of the battery.When the battery terminal volt rises up to 14.2V (adjustable) charger
disconnects Grid power to the inverter and the load on it starts running on battery power (solar power). When
the solar charging current stops load will be working from the battery bank and the battery voltage goes
down. When it reaches 11.5V (adjustable) the device reconnects AC mains (grid power) to inverter and the
blue LED goes o. Blinking of blue LED indicates low battery bank voltage. ie. below 11.7 V (adjustable) giving
warning indication to remove heavy load on inverter

In this mode inverter will be always on grid power.
What is Forced Grid to Solar Shifting
When a heavy load is applied on inverter when running on solar mode (eg;- iron box,pump set,normal fridge,
etc.) a sudden voltage drop will make MPPT to shift from solar mode to grid mode. It will only be shifted to solar
mode the very next day when battery is fully charged .If the battery terminal voltage is above the solar to grid
change over set voltage (default 11.5V) inverter load can be shifted again to solar mode by pressing and

IMPORTANT NOTE FOR ACTIVATION OF LIMITED
AMPERE BATTERY CHARGING AND EQUALIZATION CHARGING
1. What is initial limited ampere charging in MPPT charge controller ?
Maximum recommended charging current for a solar C10 inverter battery is up to 20% of the battery AH.
Batteries used in solar power system is often discharged below 11.5V every day. So it is recommended to start
initial charging with limited ampere instead of charging with maximum capacity of MPPT charge controller.
Eg: Recommended maximum charging current for a 12V,150AH lead acid battery is 30 Amp. If such a battery
is connected to the MPPT delivering above 30 amps the excess ampere entering the battery can be controlled
in the initial charging stage by activating initial limited ampere charging feature. MPPT delivers only 20% of
the battery Ah. ie.30amps to the battery
1. Ampere Limiting based on load shifting voltage:
(grid to solar shifting volt) In this mode battery charging ampere is limited in the initial stage .(if battery is
150Ah charging current will be limited to 30 amps.) When load is shifted to solar, entire ampere is shared
between load and battery.
2. Ampere limiting based on Charging mode :
In this mode also, battery charging ampere is limited in the initial stage and the limitation is stopped after the
completion of bulk charging stage. (when float charging starts)
ie.The entire charging current is never delivered to battery in float charging mode as the battery is already
charged to float charging level.
MPPT charge controllers are sun light dependent devices and they can’t deliver high ampere in the morning.
They start to charge the batteries in low ampere early in the morning. As the terminal volt of the battery
increases, charge controller shifts the connected inverter load to solar power and the current is shared to load
and battery charging.Hence the activation of limited ampere charging is not necessary in low ampere charge
controllers connected with high Ah batteries.
eg: If the charge controller delivers more than 30amp current in starting stage and the connected battery is
below 150Ah it is recommended to activate limited ampere charging option.
2. What is Equalization charging in MPPT charge controller?
When a lead acid battery is left in a discharged state for extended periods of time, non-removable sulphate
crystals are formed on the surface of battery plates that reduce the charging and discharging capacity of the
battery. Equalization charging is an over charging process of lead-acid batteries above their recommended
charging voltage, to remove sulfation and bring all cells of the battery to similar levels by increasing the
voltage to 2.50V/cell, or 10 percent higher than the recommended charging voltage. Equalization charging
also equalize acid stratification, a condition where acid concentration is greater at the bottom of stationary
batteries than at the top level. Battery experts recommend periodic equalization charging to keep the
batteries healthy (once in every three month)

SMF, VRLA, AGM, GEL Batteries.
SMF (sealed maintenance free), SLA (Sealed lead acid) and VRLA (Valve regulated lead acid) batteries are
same. Its 2 types of cells are (AGM (Absorbed glass mat) and GEL cells. They are maintenance free batteries
which do not require regular water filling, its composition of electrodes and electrolyte is same as flooded lead
acid batteries. These batteries do not need to be kept upright as the electrolyte is in the form of gel or paste.)
Un-attended equalization charging of battery is risky as there is chance for overheating of battery
plates, overflowing of electrolyte and damaging of batteries.
Remove all loads from the batteries before starting equalization charging. Fill all the battery cells with distilled
water in the required level. It is better to remove the all the lids of batteries before starting equalization
charging as the batteries will begin gassing and bubbling vigorously at the peak stage of boost charging.
Ensure the batteries are installed in a good ventilated area. Even a spark from a metal cutter, loose contact of
battery wires may cause fire hazard and explosion of batteries. During equalization charging, check the
changes in the specific gravity of acid of each cells every hour and stop charging if the gravity and voltage of
cells no longer rises during the gassing stage. Further improvement of the cell is not possible and continued
charging will spoil batteries
Enabling limited ampere charging in MPPT charge controller.
Enter settings menu 13. AMP-LT (Read page 10 for MPPT function settings)
1. Select option “0” to disable limited ampere charging.
2. Select option "1" for limited ampere charging up to the set value of 7th menu. (7.GRD-SOL) ( Grid to Solar
shifting volt 14.2V default) When kept in this mode MPPT delivers only 30 amps of continuous charging
current to the battery if the Ah is set to 150 and delivers the maximum available ampere to load and battery
charging after shifting to solar power.
3. Select option "2" for limited ampere charging up to the set value of 2nd menu. (Bulk charging limit. 14.8V
default) MPPT delivers only 30 amps of continuous charging current to the battery if the Ah is set to 150 and
release the ampere limit only after the completion of bulk charging (14.8V in default). In this mode, load is
shifted to inverter only after starting float charging (end of bulk charging)
Enabling equalization charging in MPPT charge controller.
Enter settings menu and configure menu 5.N-DAYS “0” to disable all modes of equalization charging.
Enter settings menu and configure following settings for enabling equalization tcharging:
3.EQLZ-V : Set the equalization voltage
As the equalization is an over charging process, ask a battery expert before setting the maximum applicable
upper voltage limit. Blind settings will spoil the batteries.
4.BVLC-V : Select the battery low voltage level to enable equalization charging based on battery terminal
volt. (Configure a value slightly less than inverter low voltage cut o to avoid frequent equalization charging)
5.N-DAYS : Set period of Equalization charging
N-DAYS = 0 =>Disables all modes of Equalization charging
N-DAYS = 1 =>Equalization charging starts every alternate days
N-DAYS = 2 =>Equalization charging starts every 2 days
………………………………………………………………………………..
N-DAYS = 30 => Once in a month (Recommended)
N-DAYS = 90 => Once in 3 months
N-DAYS = 180 => Once in 6 months
13.AMP-LT : Recommended to set AMP-LT “1” or “2” for controlled (limited ampere) charging to battery in
Equalization charging mode.This option is recommended because system will not shift from grid to solar till
the equalization charging is completed which helps to rise battery terminal voltage gradually and attains
maximum gravity of electrolyte and gets good backup from batteries.

Changing the default settings of MPPT charge controller
Note: Before changing the default settings values of the device, ensure the maximum ampere and voltage
ratings applicable for your battery type and brand (SMF, LEAD-ACID, GEL) This device is not designed for
direct charging of lithium Phosphate battery . Blind settings may cause severe damage to the batteries and
charge controller. Default values given are for lead acid C10 grade solar batteries.To reset to default settings
enter settings menu 14 F-RST and set the value to "1".(Refer user manual function settings page)
Refer battery user manual for recommended charging ampere and voltage for the connected batteries.
Never try to change the default settings of the device without the help of technical advice. Note down the default
settings of the device before changing. Read function settings page before changing default settings of the
device.
Entering setup mode of MPPT charge controller.
Connect the charge controller to the desired battery bank. Consecutive pressing of the ENTER button ( )
displays the existing function settings of the charger.
To enter Setup mode , keep pressing DOWN arrow button ( ) for 3 seconds & press ENTER button ( )
also without releasing DOWN arrow button ( ) for 3 seconds. Now MPPT enters setup mode , displaying
version number and model name. Press the ENTER button ( ) to scroll through the various setup menu as
shown in the function settings page.Use the UP button ( ) to increase and DOWN button ( ) to decrease the
default values. When kept idle for 5 seconds or gone through all settings menu new settings will be saved and
the device goes to normal mode.
When default settings is changed MPPT will be in Auto bypass OFF mode. To turn ON the Auto bypass mode
press and hold UP button ( ) for 2 seconds.
Before starting it is better to make a plan of your solar energy needs and ensure your existing inverter and
batteries are suitable for solar application. When a battery is charged with limited charging ampere (6AMP to
10AMP ) for long hours it delivers good energy backup. Solar charging and discharging is a daily process with
high current from solar panels. We get only 4 to 5 hours average sun light in a day and have to charge the
batteries in this time. C10 grade solar batteries above 100 Ah have the capacity to handle high current charging
and discharging. Usually inverter batteries are either C20 grade or C10 grade normal batteries. An inverter
battery is always connected to grid power and continuously charging the batteries in limited ampere for
longhours (6AMP to 10AMP) and gives good back up. That is why we don't get enough backup from normal
batteries when charged from solar power with high current. If we use normal batteries for solar charging with
limited charging current they can't be gotfully charged before evening. So always insist on C10 grade solar
batteries for solar applications. Now check your home inverter is provided with a grid charging ON/OFF switch.
Most of the branded normal type inverters are not provided with a grid charging ON/OFF switch on them.When
we use this type of normal inverter in solar o-grid system it will charge batteries from grid power and we do
not get actual solar benefit.
HOW THE CHARGE CONTROLLER DRIVES THE CONNECTED INVERTER
Most of the SMU type solar MPPT charge controllers are provided with an inbuilt relay to control grid power
to the inverter.Remove grid power phase wire from your inverter and connect to PHASE IN terminal of
MPPT.Connect a wire from the PHASE OUT terminal of MPPT to the PHASE IN terminal of the inverter. (Never
connect the neutral wire of grid power to any connectors of MPPT). When charging starts terminal volt of the
battery rises to the preset voltage 14.2 V (this value is adjustable) MPPT disconnects the AC mains to the
inverter and the connected load on the inverter works on battery power (solar power). when the battery
terminal volt goes down (in the evening or cloudy sky) and reaches 11.5 V (this value is adjustable) MPPT
reconnect grid power to the inverter. If your inverter is a normal type without a grid charging disabling switch
it will charge the batteries and we don't get the solar benefit. To overcome this it is better to limit the load on
the inverter and keep the battery terminal volt always high. Some customers use solar power only in the
daytime and shift the load to AC mains by keeping the shifting to AC mains voltage 12.0 V or more. Fitting an
external grid change over the relay system for bypassing grid power directly to load is also applicable. If we
use an inverter with a grid charging ON/OFF switch we can keep the switch in o position to avoid charging
from the grid. Only on cloudy days we can keep the switch in on position and charge the batteries from grid
power.
