Communication Connection
The inverter is equipped with two sets of RS-485 Modbus communication ports. RS-485-1 is for general
communication with personal computer. It will provide advanced communication and monitoring options.
RS-485-2 is for use with Li-battery. For detailed operation, please check your local dealer or installer.
After communication cable is connected well, insert bundled CD into a computer and follow on-screen
instruction to install the monitoring software. For the detailed software operation, please check user manual of
software in the CD.

CAUTION:
Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a
short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check with
manufacturer of air conditioner to see if it’s equipped with time-delay function before installation. Otherwise, this
inverter/charger will detect overload fault and cut off output to protect your appliance but sometimes it still
causes internal damage to the air conditioner.
