Step 7: Plug the AC connection socket into AC grid terminal of the inverter.
CAUTION:
earthed before operating this hybrid inverter no matter the grid is connected or
not.
To prevent risk of electric shock, ensure the ground wire is properly
PV Module (DC) Connection

CAUTION:
breaker between inverter and PV modules.
NOTE1: Please use 1000VDC/20A circuit breaker.
NOTE2: The overvoltage category of the PV input is II.
Before connecting to PV modules, please install separately a DC circuit
Please follow below steps to implement PV module connection:
WARNING:
are acceptable: single crystalline and poly crystalline with class A-rated and CIGS
modules.
To avoid any malfunction, do not connect any PV modules with possibility of
leakage current to the inverter. For example, grounded PV modules will cause
leakage current to the inverter. When using CIGS modules, please be sure NOT
grounding.
CAUTION: It’s requested to have PV junction box with surge protection.
Otherwise, it will cause inverter damage when lightning occurs on PV modules.
Because this inverter is non-isolated, only three types of PV modules
Step 1: Check the input voltage of PV array modules. The acceptable input voltage of
the inverter is 350VDC - 900VDC. This system is only applied with two strings of PV
array. Please make sure that the maximum current load of each PV input connector is
18.6A.
CAUTION:
the system before wire connection.
Exceeding the maximum input voltage can destroy the unit!! Check
