The Content

A. General Instruction
1. All instructions should be read and understood before attempting to install, operate,
and maintain your Off-Grid MPPT PCU.
2.The handling, installation & maintenance of the battery associated with this
equipment, must be done in accordance with the instructions & safety precautions
given by the battery manufacturer.
3. Risk of a possible electrocution is possible when the battery is connected to the PCU.
Therefore, do not forget to disconnect the batteries, grid, PV Module, load before any
service is to be done on the PCU.
4. Installation, maintenance & repair of the equipment should be undertaken by trained,
experienced and authorized service or electrical personnel.
5. To disconnect, turn off all MCBs located at the back panel of PCU.
We request you to read the Manual prior to installation, performing start
up procedures, system operation & maintenance. Should you require any
assistance for more information on installation, please contact our India
Toll Free No. 1800 419 8610
B. Safety Warnings
1. Environmental Safety
PCU packing must be recycled in compliance with regulations.
Battery contains Lead and is dangerous substance for the environment hence
same shall be dispose of by Govt. approved agency only.
Important Safety
Instructions
SOLAR OFF-GRID MPPT PCU, PAGE 01, Ver. 1.0

2. User Safety
Grounding of the PCU & PV Module is necessary before connecting power supply.
Therefore, connect to ground prior to commissioning. Improper connection may
damage the device and lead to injuries.
3. Product Safety
Ÿ Suitable upstream protection must be installed with easy access to operators.
PCU should be installed at dry area, free from any water seepage and water
logging.
Ÿ Place the PCU in a room with proper ventilation and safe distance. All ventilation
apertures must be kept free and clean. Refer to manual to perform installation.
Ÿ Avoid installing the PCU in location under direct sunlight, running water, or
excessive humidity.
Ÿ Routine preventive check should be carried out.
Ÿ Store the Solar PCU in its original packing keeping the arrow on the box
pointing vertically upward.
Ÿ Store it in dry location. Storage temperature must be between 0°C to 70°C.
Ÿ Suitable handling equipment should be used for handling of PCU.
Ÿ The route / passage up to the installation site and the actual foundation
location must be capable of supporting the weight of the Solar PCU and its
accessories.
Hazardous voltage levels are present within the PCU. PCU should
be opened by qualified engineer only.
The interior of the Solar PCU cubical, after it is installed, has
hazardous AC & DC voltages on exposed terminals and printed circuit
boards. This condition prevails even when all the switches are OFF.

MPPT PCU
Installation
Please immediately contact Service person, Dealer or Transport agency if the
following conditions occur - 1. Any damage observed, either external or
internal. 2. Any accessory is missing or damaged.
SOLAR OFF-GRID MPPT PCU, PAGE 03, Ver. 1.0
A. Visual Check of PCU
When you receive your Off-Grid MPPT PCU, please carry out visual check for any damage
during transport.
B. PCU Installation Guide
Ÿ The system must be installed in a dry & clean room. To have proper ventilation, the user
must ensure enough air exchange in the room.
Ÿ Never install the equipment near liquids or in an excessively damp environment.
Ÿ Never block the ventilation grates.
We suggest the following for best results of installation -
- Minimum distance from the rear wall = 500 mm
- Minimum distance from the top = 500 mm
- Minimum distance from the front wall = 500 mm

C . Installation Safety Instructions
Ÿ Keep the Battery, PV Module, Grid Input & Output MCBs in "OFF" position during
installation.
Ÿ Connect Grid Input, PV Module & Battery supply to PCU.
Ÿ Ensure correctness of the polarity of battery & Solar PV Module connections.
Ÿ Ensure proper earthing of the equipment.
Ÿ Connect load cables.
Ÿ For PV Module readily accessible disconnection device (MCB/MCCB) shall be
incorporated in the distribution.
Ÿ After complete installation to power up system switch ON the Batt. MCB, for battery
voltage >96V . Press Soft start switch for 30 sec to charge the capacitor before
switching ON the battery MCB. Solar Charging will start.
Ÿ Press the Reset Switch to PCU ON. Thereafter switch ON the Output MCB. Now load will

Know Your Off-Grid
MPPT PCU
A. PCU System Description
Your Off-Grid MPPT PCU is a pure sinewave single phase output system.
In normal mode, PCU operates from battery or solar power source and produces
single phase AC output to cater the load requirement.
MPPT based Solar charge controller, supplies DC power for battery charging as well as
for the PCU.
If solar is unavailable or is available in lesser amount, connected batteries will go into
discharge mode and grid input will get triggered automatically at certain
predetermined battery voltage level. Grid Input source takes care of output load and
starts battery charging till sufficient battery charge level is reached.
1. Internal Components
System comprises the following main control boards.
a) Control Board
b) Display Board
a. Control Board: It controls operation of MPPT charger and PCU. It contains power
modules of MPPT and PCU. MPPT receives DC supply from solar array and provides
charging voltage to battery and DC voltage for PCU operation. This board also
contains Power relays for grid and PCU, based on signal from DSP board transfer
operation is controlled and Output is available at load.
b. Display Board: It receives all inputs from Control Board. It displays parameters of PV
Module, Battery, PCU and Grid.
2. Operating Priority
a. Smart Mode/SBG Priority - Your PCU gives fisrt priority to solar, second priority to
battery and third priority to grid in this case.
b. PCU Mode/SGB Priority - Your PCU gives fisrt priority to solar, second priority to grid
and third priority to battery in this case.
c. Hybrid Mode - In this mode PCU works with solar as well as batteries. Grid charger
takes place only when solar power is not available & battery discharges up to battery
low level trip. It will charge the batteries up to certain limit to maintain float level of
battery.
