Afore Single Phase 4kW Hybrid Inverter (AF4K-SL)

Description

Single Phase Hybrid Inverter: AF4K-SL

The Afore AF low voltage Series storage Inverters are designed to increase energy independence for homeowners. The power range is from
1kW to 6kW, compatible with low voltage (40-60V) batteries.
Energy management is based on time-of-use and demand charge rate structures, significantly reduce the amount of energy purchased
from the public grid.
Thanks for the UPS function (switch time < 10ms), 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 integrated with Arc Fault Circuit Interrupter (AFCI) and Rapid Shutdown.
