Consider the below points before selecting where to install:
1. Do not mount the inverter on the surface of flammable construction materials. 2. Mount on the surface of a solid material.
3. Install the inverter at a visible place in order to the LCD display can be read easily.
4. For proper air circulation and dissipate heat ,make sure there is 20 cm distance from the two side,
50 cm distance from bottom of the unit.
5.The ambient temperature should be between -10°C and 50°C to ensure optimal operation.
6.The recommended installation position is to be adhered to the wall vertically.
7.Be sure to keep other objects and surfaces as shown in the diagram to guarantee sufficient heat dissipation and to have enough space for collecting wires.
Suitable for mounting on concrete or other non-combustible surface only
4.4 Battery Connection
CAUTION: For safety operation and regulation compliance, it’s requested to adopt a separate DC
over-current protector or disconnect device between battery and inverter. It may not be necessary to
have a disconnect device in some applications, however, it’s still need to adopt over-current
protection device. Please refer to typical amperage in below table as required fuse or breaker size.
WARNING! All wiring must be performed by a qualified personnel. WARNING! It’s very important for system safety and efficient operation to use appropriate cable for
battery connection. To reduce risk of injury, please use the proper cable as below.

CAUTION! Before connection the DC breaker, be sure positive (+) must be
connected to positive (+) and negative (-) must be connected to negative (-).
4.5 AC Input/output Connection
CAUTION! Before connecting to AC input power source, please install a separate
AC breaker and lightning arrester between inverter and AC input power source.
This will ensure the inverter can be securely disconnected during maintenance
and fully protected from over current of AC input. The recommended spec of AC
breaker is 32A for 3.5KVA and 50A for 5.5KVA. There are two terminal blocks
with “IN” and “OUT” markings. Please do NOT connect input and output
connectors wrong. WARNING! All wiring must be performed by a qualified
personnel. It’s very important for system safety and efficient operation to
use appropriate cable for AC input connection. To reduce risk of injury,
please use the proper recommended cable size as below.

Over current or surge.
Bus voltage is too low.
Output voltage is unbalanced. PV input voltage is beyond the specification.
Restart the unit, if the error happens again, please return to repair center.
Reduce the number of PV modules in series.
