About the Felicity Solar IVPS5048P1G1-LV 4kW Single-Phase Inverter / Charger

The Felicity Solar IVPS5048P1G1-LV is a single-phase off-grid inverter charger that delivers 4 kW of rated output power, 5 kVA apparent, from a 48 V battery bank to a 110-127 V AC output, in pure sine wave, with a 15 ms transfer time between utility and battery. The LV designation shows in those AC figures: nominal input 110-120 V, output 110-127 V, wired L-N. The low-frequency, transformer-based design carries twice rated load for 5 seconds and is motor-start capable, so pumps and compressors start without tripping it. AC input accepts 80-140 V in appliance mode and 90-140 V in UPS mode at 50/60 Hz, passing through up to 63 A; with no battery connected there is no pass-through. Charging is three-stage - boost CC, boost CV, float - up to 50 A, at 57.6 V bulk and 54.4 V float, across a 42-63 V battery window covering AGM, flooded, lithium-ion and self-defined profiles. RS485 carries BMS data, up to 9 units run in parallel, and line-mode efficiency is above 95%. The IP21 chassis measures 494 x 420 x 195 mm and weighs 31.35 kg net. We are an authorised Felicity Solar distributor and supply the IVPS5048P1G1-LV from our own stock.

Frequently Asked Questions

What is the rated output power of the IVPS5048P1G1-LV?

It is rated at 4 kW of output power, 5 kVA apparent, on a single phase, and its backup rated output power is also 4 kW. The low-frequency, transformer-based design carries twice rated load for 5 seconds, and the unit is motor-start capable.

What battery does the IVPS5048P1G1-LV run on, and how fast does it charge?

Nominal DC input is 48 V, with a working battery range of 42-63 V and start-up at 46 V. Charging is three-stage - boost CC, boost CV, float - at up to 50 A, with 57.6 V bulk and 54.4 V float and a 61.0 V maximum. AGM, flooded, lithium-ion and self-defined profiles are selectable, and BMS data runs over RS485.

What AC input and output does it handle?

AC output is 110-127 V single phase, L-N, at 50/60 Hz, pure sine wave, with output voltage regulation of 5%. Nominal AC input is 110-120 V; the unit accepts 80-140 V in appliance mode or 90-140 V in UPS mode, transfers in 15 ms and passes through up to 63 A. There is no pass-through without a battery connected.

Can units be paralleled, and what are the physical specifications?

Up to 9 units can run in parallel. Each unit measures 494 x 420 x 195 mm and weighs 31.35 kg net, 35.05 kg gross, in a 607 x 540 x 290 mm carton. The chassis is IP21 with intelligent air cooling, an LCD and LED display, and an operating temperature range of 0-40 C.
