About the Felicity Solar IVEM3048-SALV 3kW Single-Phase Off-Grid Solar Inverter

The Felicity Solar IVEM3048-SALV is a 3 kW single-phase off-grid solar inverter that delivers 127 V at 60 Hz from a 48 V battery bank, rated 3 kVA of apparent power, with one MPPT tracker accepting up to 4 kW and 15 A of PV across a 120-450 V working range. The -SALV build is the 127 V, 60 Hz edition: nominal AC input is 127 V, accepted from 65-140 V in appliance mode and 90-140 V in UPS mode, with transfer in 20 ms on appliance mode and 10 ms on UPS mode against a 50 ms general transfer time. Peak efficiency is 93% and line-mode efficiency exceeds 95%. Output is regulated to within 5% at up to 30 A, with 2x rated surge for 5 seconds. Charging runs to 60 A from solar or AC, boosting at 56.4 V and floating at 54 V across AGM, Flooded, Li-Ion and Self-Defined batteries over RS485. The wall-mounted IP21 chassis measures 440 x 328 x 130 mm at 11.9 kg net. The warranty term is 2 Years. We are an authorised Felicity Solar distributor and supply the IVEM3048-SALV from our own stock.
