3. INSTALLATION
3.0 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:

This image shows a typical single-line diagram showing use of SPD and earth connection there of.

3.4 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.

S>G>B*
Suitable for the case where customers wants no
battery charging through grid supply. This mode
allows the battery to discharge approx. 40%-50% then
AC loads switch to grid source, if grid supply available.
MODE-2
(default)
S>G>B
This mode allows the battery to discharge approx.
40%-50% then A C loads switch to grid source, if grid
supply available. This mode allows the battery
charging through grid when battery discharge more
than 80%
MODE-3
S>B>G
This mode allows the battery to discharge aprox. 60%-
70% then AC loads switch to grid source, if grid supply
available. This mode allows the battery charging
through grid when battery discharge more than 80%.
MODE-4
S>G>B**
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 approx. 80% of its capacity
to make sure to get more battery backup in night time
as compared to above 3 modes.
MODE-5
G>S>B
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.
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.
