5 Installation and Electrical Connection
5.1 Safety
Danger to life due to fire or explosion
Despite careful construction, electrical devices can cause fires. Do not install the inverter on
easily flammable materials and where flammable materials are stored.
Risk of burns due to hot enclosure parts
Mount the inverter in such a way that it cannot be touched inadvertently.
All electrical installations shall be done in accordance with the IEE Wiring Regulations.
Do not remove the casing. The inverter contains no user serviceable parts. Please refer
servicing to qualified service personnel.
Carefully remove the unit from its packaging and inspect for external damage. If you find
any imperfections, please contact your local supplier.
This unit is designed to feed power to the public power grid (utility) only. Do not connect
this unit to a generator. Connecting the inverter to external devices could result in
serious damage to your equipment.
When a photo-voltaic panel is exposed to light, it generates a DC voltage. When
connected to this equipment, a photo-voltaic panel will charge the DC capacitors.
78
All wiring and electrical installation should only be conducted by a qualified electrician.
Select the installation location so that the status display can be easily viewed.
Do not install the inverter on structures constructed of flammable materials.
The humidity of the installation location should be 0 - 95%, without condensation.
The installation location must be safely accessible to get to at all times.
Vertical installation or tilted backwards by max. 15° and make sure the connections
of inverter are at the bottom. Never install horizontally and avoid forward and
sideways tilt.
Be sure that the inverter is out of the children’s reach.
Do not put anything on the inverter. Do not cover the inverter.
Do not install the inverter near television antenna or any other antennas, antenna
cables.
The Inverter requires adequate cooling space. Provide the best ventilation for the
Inverter to ensure the heat escapes adequately. The ambient temperature should be
below 40° C to ensure optimum operation.
The inverter shall not be installed where in direct contact with water or in direct
sunlight.

Figure 4
5.2 Selecting The Installation Location
This is guidance for the installer to choose a suitable installation location, to avoid
potential damages to the device and operators.
The unit shall be mounted at least 914 mm (3 feet) above the ground.
The installation location must be suitable for the inverter's weight and dimensions
for a long period of time.

The inverter should not be installed in direct sunlight, direct heavy water sources or unstable
locaons. We recommend that the inverters be installed at a locaon with some cover or protecon.
Observe the minimum clearances to walls, other inverters or objects as shown in the
diagram below in order to guarantee sufficient heat dissipation.

PLEASE NOTE: If damage arises to the inverter as a result of insufficient fixings so as
to withstand the load of the inverter, or the installation is not carried out in accordance
with the manufacturer’s requirements, the warranty may be voided.
Ambient Dimensions Using Inverters In Series
There must be sufficient clearance between the individual inverters to ensure that
the ambient air from the adjacent inverter is not taken in.
If necessary, increase the clearance spaces and make sure there is enough fresh air
supply to ensure sufficient cooling of the inverters, and heat dissipation.
5.3 Mounting The Inverter With Bracket
In order to avoid electrical shock or other injury, inspect existing electrical wiring
systems or plumbing installations before drilling holes for bracket fixings
The dimension of bracket as in [Figure 8]:
Using the mounting frame as a template, drill holes as illustrated in the image below.
Fix The Bracket With 4PCS
M6X50 Expansion Bolt

5.4 Fixed The Inverter On The Wall
Falling equipment can cause serious or even fatal injury. Never mount the
inverter on the bracket unless you are sure that the mounng frame is
securely mounted on the wall.
Raise the inverter a lile higher than the bracket. Consider the weight
during the process to maintain the balance of the inverter. Hang the inverter
on the bracket through the hooks on bracket.
Aer confirming the inverter is fixed securely, insert the four M4
safety-locking screws on the le and right side to prevent the inverter from
being lied off the bracket.

Figure 10
Figure 11
5.5 Check Inverter Installation Status
Check the mounting of the inverter by trying to raise it from the bracket. The
inverter should remain firmly attached.
Please ensure that the correct mounting surface is selected to allow for vibration of
the inverter during normal operation.
5.6 Electrical Connection
High voltages which may cause electric shocks are present in
the conductive parts of the inverter. Prior to performing any
work on the inverter, disconnect the inverter on the AC side,
battery side.
Do not reverse the polarity of the battery! It will damage the
inverter and void any warranty.
Danger To Life Due To Lethal Voltages!
5.6.1 Safety
Danger of damage to electronic components due to electrostatic
discharge. Take appropriate ESD precautions when replacing and
installing the inverter.
Before connecting the DC power cables, the AC supply must be
earthed.

Output Connection Terminals
The cable length should not exceed 50 m as the resistance of the cable will
consume inverter output power and reduce the inverter efficiency.
You must install a separate AC circuit-breaker or other load disconnection unit
between the inverter and utility, in order to ensure that the inverter can be safely
disconnected under load.

5.6.4 Connect To The Back-Up
The back-up can provide a maximum output power of 2500w. You can connect the
essential load to the back-up terminals.
You must install an AC Isolator or other load disconnection unit between the inverter
back-up output and the essential load, in order to ensure that the inverter can be
safely disconnected under load. We suggest the separate unit spec is 20A.
The back-up MAX output power is 2500w. If the load is greater than 2500w, the
inverter will stop outputting and draw from the grid. The output power of back-up
depends on the battery capacity.
We suggest the AC separate unit spec as follow,
NOTE

5.6.5 Connect To The Battery
Before connecting to the battery, you must install a separate DC breaker (not less
than 120A) between the inverter and battery. That will ensure the inverter can be
securely disconnected during maintenance.
Reversed polarity will damage the inverter!!!
It is very important for system safety and efficient operation to use appropriate
cable for battery connection. To reduce risk of injury, you much use the proper
recommended cable size, refer to the following;

The battery must be installed in accordance with the manufacturer ’s instructions.
The MAX charge / discharge current of the inverter is 50A.
The inverter ’s battery rated voltage is 48V. The battery series connection voltage
must not exceed 48V or it will damage the inverter and void any warranty.
Follow the below steps to implement the battery connection:
(1) Check the battery nominal voltage meets the inverter spec.
(2) Disconnect the breaker between inverter and battery.
(3) Check out the polarity of the battery and the inverter.
(4) Terminate battery DC cables by means of the lugs provided.
(5) Screw the DC cable to the inverter's battery input terminal.
(6) The correct baery technology must be selected upon commission, so
that it can be controlled via the BMS
Figure 19
Before you install the BAT.NTC, you must turn off the inverter,
check all the separate breakers are off, and the inverter's LED is
off. Then you can safely install the BAT.NTC terminal to the
inverter.
Danger to life due to voltages!
we recommend using the Solarshop appointed lithium battery,
because the battery BMS communication has been designed to
be compatible with the Solarshop Hybrid Inverter.
NOTE
5.6.6 Connect CT Clamp Or Mid Approved Meter To Inverter
In the system, a CT or mid approved meter must be installed to monitor the
power of the house to decide the inverter status: charge or discharge.
CT or meter must be installed at the origin of supply. In this case, the
inverter can monitor all household consumpon of power. According to the
sensor, the inverter will control the PV power feeding to the grid to balance
the level of household power use.
Place the CT reader inbetween the meter and the inverter. This must be positioned
in front of local load and around the LIVE wire only with the arrow pointing
TOWARDS the inverter.
