Description
The Afore AF low voltage series storage Inverters are designed to increase energy independence for homeowners. The power range is from 1kW to 3.6kW, 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.
Support for Time-of-use Optimization
Arc Fault Circuit Interrupter (AFCI) (Optional)
Build in Anti-feed-in Function
Smart Monitoring & Remote Firmware Upgrade
