1.PV Panel Grouping
:
Using required Solar MC4 connectors and parallel connectors,
group the PV panel array according to the recommended grouping chart provided.
Good quality weather proof solar cables must be used.
2.Battery Bank Setup
:
If more than one battery is used, Connect the interlinking
cables (16 sq.mm minimum) tightly and check each battery separately for specific
gravity and backup.
3.MPPT Charge Controller Installation:
-
- Mount the MPPT charge controller vertically on the wall.
- Never keep any object on the device blocking the cooling fan.
- Avoid exposure to rain, direct sunlight or high temperature.
- Remove the terminal cover of the device and make sure the device is switched off.
- Connect the device to the battery bank using 16sq.mm/10Sq.mm standard cables.
- Connect the cables from PV panels to the solar terminals of the device with correct polarity.
- Switch ON the Power switch of the device.
-Three LED Indicators and cooling fan of the device starts functioning for 5 seconds and goes
off.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 are same when MPPT is powered
ON.
The Charger starts functioning when the PV Panel voltage detected is higher than
the connected battery bank voltage and green LED lights up. If the PV panel voltage
goes below the battery bank voltage the green indicator goes off. When the device
detects more than 2A charging current to the battery, RED LED lights up. If the
current is less than 2A the RED LED goes off. When the battery voltage reaches
14.0V(Configurable) the BLUE LED lights up and the phase input to the inverter
connected through the MPPT will be blocked. Now the load starts functioning on
inverter (Solar). When the solar charging current stops the load will be taken from
the battery bank and the battery voltage goes down. Once it reaches
11.0V(Configurable) the device change over the load from inverter to grid power and
the blue LED goes off. Blinking blue LED indicates Low battery bank voltageie.11.7V
(Configurable)giving warning to remove heavy loads.The blinking of green LED
indicates sharing of solar current for battery charging and connected load. Solar/Grid
status can also be monitored remotely by connecting an LED to the Solar/Grid
Monitor Port for a distance up to 30 meters with wire.
- Automatic Grid/Solar power Change Over :
If the Automatic Grid/Solar power Change
Over is required, follow the instructions below: -
Connect the grid power phase wire (using
4sq.mm/6sq.mm) to the ‘Phase In’ part of the terminal on the device. Connect
another wire from the ‘Phase Out’ part of the terminal to the input phase connector
of the inverter. (Never connect the neutral of the grid power to any terminal of the
charger. Refer Connection diagram provided).

exceed the Maximum panel voltage mentioned above for each battery
bank!

1) Solar panels should be grouped in such a way that the maximum Open
Circuit Voltage (Voc) of the panels connected in series should not exceed the
Maximum PV panel voltage recommended.
2) Safety precautions must be taken while grouping and connecting PV panels
to the charge controller with high Voc input. (750 Volt DC current from the PV
panel is highly dangerous. Never touch the terminals without safety glows)
3) Extreme care should be taken while connecting High voltage solar power
systems.
4) Earthing and wiring of high power solar system must be done under the
supervision of a qualified electrical engineer
5) Never connect the PV panel connection to the battery input or the connection
of the batter
ies to the PV input.
6) Never connect any of the grid line to any of the DC (PV or Battery) connection
terminals. Use always weather proof highly insulated solar DC wires for PV
panel grouping.
7) The installation and use must comply with the local safety instructions and
standards in force.
8) Never use a flame or any kind of spark producing device near fully
charged batteries as it may cause an explosion of the batteries and fire
hazard.(eg: Checking battery water level under a candle flame light, spark
from a metal cutter or spark from loose contact of battery connecting
wires)
9)
We disclaim all responsibility and liability for damage, costs or losses resulting
from an installation that does not comply with the instructions, a faulty operation
or inadequate maintenance.
10) The use of the charger is in any case under the responsibility of the
customer.
