3. INSTALLATION
3.1 LOCATION AND PLACEMENT
3.0.1 PCU
The Inverter should be placed in accordance with the following:
Unpack PCU completely then unwrap the stretch film from PCU.
In a well-ventilated room.
Placed on a raised platform for better insulation from the ground, protection from water, and so on.
Gas cylinders, spray and other inflammable items should not be placed near it.
Should not be placed in direct sunlight, near running water or at excessively humid location.
In case the system is not going to be installed immediately, it must be stored carefully in vertical
position, as indicated on the packing and stored in a dry and sheltered room. Cover it with an
envelope (paper/light material cover) so that it is protected from dust.
If the inverter installation is over 6 months, be sure to charge batteries for at least 8 hours before
the first use.
3.0.2 BATTERY
Battery should be placed on a 3”(inch) ramp above from ground.
Battery bank terminals should always be insulated to avoid and electrical shock.
Batteries should preferably be placed in a separate room to avoid acidic fumes.
Length of cable from battery to PCU should be kept to minimum to avoid the losses. Cable sizing
should also be done keeping in mind to minimum the losses.
3.0.3 PV
Place the solar panels (PV) in the direction of maximum duration time of sun.
There should not be shadow of any object on the panel.
Should be placed at sufficient height.
Panel should be fixed properly.
Since India is located in northern hemisphere so solar panel’s face should true south direction.
Solar panel tilt angle lies between 10°-30° but it should be determined according to the latitude of
your position.
3.0.4 SURGE PROTECTION DEVICE (SPD)
Surge Protection are a part of plant installations and hence, should be installed in addition to
protection offered in PCU. Type and size surge protections vary from site to site and adequate
consultation should be done with a subject matter expert before selection of SPD.
Apart from SPD in AJB used for solar protection, additional SPD is recommended before PCU inside
the room.
Suitable SPD on AC side (both Grid and Load) is mandatory inside the room before PCU to avoid any
damage to it caused by surges. A typical such schematic drawing can be seen in figure below for
single phase PCU. An installer may contact some expert and use alternate scheme similar to this
reliable working of PCU and site.
See the image below on next page:

3.5 EARTHING
Earthing of any equipment is required to ensure that the chassis of the equipment is at ground
potential and the user does not experience any shock in case of contact.
For SPDs to operate and protect the equipment against lightning, earthing is mandatory.
Quality of earting and related values are important for adequate protection and vary from site to site,
and equipment to equipment.
Earthing kit contains rod and clay-salt mixture.
For earthing, dig a 4-5 feet hole in ground and put the rod with mixture and water.
Connect the earth wire from house to clamp.
It is advisable to have a proper earthing near your house or solare panels.
Please ensure that earth connection of SPD as per section 3.0.4 above is as drawing.
3.6 STARTING UP THE PCU
Check all the connections twice before starting the PCU.
Ensure that:
Battery terminals (+ve to +ve & -ve to -ve) are connected tightly and properly.
Load is connected properly.
AC Mains is connected properly.
PV is connected properly.
Check the polarity correct.
After checking all the connections, Switch on the Battery MCB first.
After switching on the MCB, the display is switched ON.

4.4 LED INDICATION
POWER : This green LED indicates PCU’s control circuitry is power ON.
INVERTER ON : This yellow LED glows when AC load is on INVERTER.
SOLAR ON : This yellow LED glows in steady state - this tells that the solar present and the
charging is completed/stoped. When blinking, it tells the solar is present and the charging is in
process
GRID ON : This yellow LED glows in steady state - this tells that grid is present and the load are
bypassed on GRID supply. When blinking with 1 second interval, it tells that (i)the grid is present, (ii)
the grid charging is in process and , (iii) the load is running on GRID supply. When blinking with a 5
second interval, it means that the GRID supply is available and the loads are running on PV+Battery.
BATT LOW : This red LED glow when your battery is low/discharged. Once Battery voltage falls below
Battery Under Voltage set value; Inverter will shut down and disconnect the load to stop further
discharging of battery. Next, “BATT. LOW” indication will appear on the display. Now Inverter will
again given the O/P to load only when Battery Voltage rises up to more than float voltage set value.
FAULT : This red LED glow if any Fault occurs.
INV ON/OFF : Press and hold button to turn on your PCU, green LED nearby button will start glowing,

4.6 FAULT ANALYSIS
4.6.1 FAULT / ALARM INDICATION VIA BUZZER
In the PCU system, if any fault/alarm occurs then an audio alarm indication is generated by a buzzer -a
continuous beep sound. By pressing ENTER key after checking the fault type in LED/LCD, buzzer sound gets
deactivated.
4.6.2 FAULT DISPLAY
If any fault occurs in the PCU system, predefined fault no. start display in upper right side of the LCD display
with the FAULT*--- as a prefix with each fault number. The lists of fault name are given in the Table 4 as per
their respective fault number/codes.
Table 4
FAULT NAME IN DISPLAY
FAULT DESCRIPTION
SYSTEM TRIP/OFF
When system Shuts Down due to any fault/internal error
INVERTER UNDER VOLTAGE
When Inverter O/P Voltage goes below inverter under voltage set value
INVERTER OVER VOLTGE
When Inverter O/P Voltage goes above inverter over voltage set value
BATTERY UNDER VOLTAGE
When Battery Voltage goes below the battery under voltage set value
BATTERY OVER VOLTAGE
When Battery voltage goes above the battery over voltage set value
SOLAR CHARGE OVER LOAD
When Over Rated PV panel connected to the system
PV OVER VOLTAGE
When PV panel or PV string voltage connected beyond the maximum
allowe PV voltage range value
SYSTEM OVER LOAD
When Inverter O/P Load goes above the rated system
GRID UNDER FREQUENCY
When Grid/DG supply frequency goes below the under frequency set
value
GRID OVER FREQUENCY
When Grid/DG supply frequency goes above the over frequency set
value
SHORT CIRCUIT
It Indicates that Inverter O/P short circuited
SYSTEM OVER TEMPRATURE
When temperature of inverter system goes above the safe range
GRID BACK FEED
When Grid supply connected to the load point directly
MAINS OVER VOLTAGE
When mains voltage goes above the set grid over voltage value
MAINS UNDER VOLTAGE
When mains voltage goes below the set grid under voltage value

5. OPERATING MODES AND LOAD CHART
5.1 DETAILS OF PRIORITY MODES
Note: Above stated battery’s SOC in percentage is estimated (based on Battery Voltage only) but not
actual. This holds true for all percentage mentioned in the table above.
Table 5
MODES
EXPLANATION OF MODE / REASON TO SELECT THE MODE
Super
Saver 40
Solar+Battery will run loads till battery reaches 40% DOD. At 40% DOD, grid will bypass to load,
and solar power if available will charge the battery. Grid charging of battery will start if battery
reaches 60% DOD. (only applicable if grid charging is enabled)*
Super
Saver 50
Solar+Battery will run loads till battery reaches 50% DOD. At 50% DOD, grid will bypass to load,
and solar power if available will charge the battery. Grid charging of battery will start if battery
reaches 70% DOD. (Only applicable if grid charging is enabled)*
Super
Saver 60
Solar+Battery will run loads till battery reaches 60% DOD. At 60% DOD, grid will bypass to load, and
solar power if available will charge the battery. Grid charging of battery will start if battery
reaches 80% DOD. (Only applicable if grid charging is enabled)*
Backup
Mode
Suitable for areas where grid supply is available only for 6-8 hours in a day. So, whenever grid
available it charges the battery up-to more than 80% of its capacity to make sure to get more
battery backup in night time as compared to above 3 modes.*
No Solar
Suitable for areas when sufficient solar power is not available for long duration (i.e. in rainy days
or where solar panel non available due to some reason). By selecting this mode PCU will run like
conventional home inverter.

5.3 LOAD CHART & BATTERY SIZING
PCU must be chosen as per load requirement, as this affects the life of your battery as well as the
PCU. Manufacturer shall not be responsible for the selection of mode as well as the size of the
PCU (that can only be determined by the installer/end-user).
