Communication Connection Please use supplied communication cable to connect to inverter and PC. 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 inside of CD. Dry Contact Signal There is one dry contact(3A/250VAC) available on the rear panel. -
Page 14: Battery Charger
Battery Charger The inverter is equipped with an active PFC (power factor correction) multistage battery charger. When AC voltage is in the range of 154~260VAC, the charging current is 100%. The inverter is with a strong charging current, and the charge current can be adjusted from 10A~40A． There are mainly 3 stages: Bulk Charging: This is the initial stage of charging. -
Page 15: Battery Equalization
Battery Equalization Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalizationalso helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery. -
