For optimum operation of this inverter/charger, please follow required spec to select appropriate cable
size. It’s very important to correctly operate this inverter/charger.
8.
Be very cautious when working with metal tools on or around batteries. Dropping a tool could spark or
short circuit batteries, or other electrical parts, and could cause an explosion.
9.
Please strictly follow installation procedure when you want to disconnect AC or DC terminals. Please
refer to INSTALLATION section of this manual for the details.
10. One piece of 150A fuse is provided as over-current protection for the battery supply.
11. GROUNDING INSTRUCTIONS -This inverter/charger should be connected to a permanent grounded
wiring system. Be sure to comply with local requirements and regulation to install this inverter.
12. NEVER cause AC output and DC input short circuited. Do NOT connect to the mains when DC input

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 requested to use PV junction box with surge protection. Otherwise, it will cause damage
on inverter when lightning occurs on PV modules.
