WARNING!:
It's very important for system safety and efficient operation to use
appropriate cable for PV module connection. To reduce risk of injury, please use the
proper recommended cable size as below.

WARNING:
Because this system is non-isolated, only three types of PV modules are
acceptable: single-crystalline, poly crystalline with class A
‐
rated and CIGS modules. To
avoid any malfunction, do not connect any PV modules with possible current leakage to
the system. For example, grounded PV modules will cause current leakage to the system.
When using CIGS modules, please be sure NO grounding.
CAUTION:
It’s requested to use PV junction box with surge protection. Otherwise, it will
cause damage on system when lightning occurs on PV modules.
PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters
1.
Open circuit Voltage (Voc) of PV modules not exceeds maximum PV array open circuit
voltage of system.
2.
Open circuit Voltage (Voc) of PV modules should be higher than minimum battery voltage.

PV Module Wire Connection
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
2. Suggest to put bootlace ferrules on the end of positive and negative wires with a proper
crimping tool.
3. Fix PV wire cover to the system with supplied screws as shown in below chart.
