WARNING: Because this inverter 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 inverter. For example, grounded PV
modules will cause current leakage to the inverter. When using CIGS modules, please be sure NO
grounding.
15. CAUTION: It's required to use PV junction box with surge protection. Otherwise, it will cause damage
on inverter when lightning occurs on PV modules.
