Description
The Afore AF low voltage Series storage Inverters plus series are designed to increase energy independence for homeowners. The power range is from 4kW to 6kW, compatible with low voltage (40-60V) batteries.
Energy management is based on time-of-use and demand charge rate structures, which significantly reduce the amount of energy purchased from the public grid.
Thanks for the UPS function (switch time < 10ms), that enables the crucial loads power on during outages. Additionally, under the backup operation mode, the inverter provides you up to 150% peak output overloading.
The AF low voltage series storage inverters are integrated with Arc Fault Circuit Interrupter (AFCI) and rapid shutdown.
Arc Fault Circuit Interrupter (AFCI) (Optional)
Charging and discharging power is greater
Smart Monitoring & Remote Firmware Upgrade
Off-grid mode, the maximum load can be
