About the Felicity Solar IVPS7548 6kW Single-Phase Inverter / Charger

The Felicity Solar IVPS7548 is a 6 kW single-phase off-grid inverter-charger for a 48 V battery bank. It is rated 7.5 kVA of apparent power, delivers a pure sine wave at 220 V and 50/60 Hz, and charges at up to 60 A from utility or generator supply. Its low-frequency topology carries twice rated power for 5 seconds, so motor loads such as pumps and compressors start without tripping out. Two AC input windows decide how it behaves: UPS mode holds 170-280 V for sensitive electronics, while appliance mode widens to 90-280 V on weak grids, with a 15 ms transfer time either way. Charging runs a three-stage boost CC, boost CV and float profile at 57.6 V bulk and 54.4 V float, covering AGM, flooded, lithium-ion and self-defined banks, with RS485 for BMS data and RS232 for monitoring. Peak efficiency is 90%, above 95% in line mode, and up to six units run in parallel. The unit measures 494 x 420 x 195 mm, weighs 29.1 kg and is rated IP21 for indoor mounting. We are an authorised Felicity Solar distributor and supply the IVPS7548 from our own stock, with technical support before and after the sale.

Frequently Asked Questions

What is the rated output power of the Felicity Solar IVPS7548?

It is rated 6 kW of real power and 7.5 kVA apparent, single phase at 220 V and 50/60 Hz, with a pure sine wave output. The low-frequency design carries twice rated power for 5 seconds, so motor loads such as pumps and compressors start without tripping the inverter.

Which battery bank does the IVPS7548 need?

A 48 V bank. It operates from 42 V to 63 V, starts up at 46 V, and charges at up to 60 A through a three-stage boost CC, boost CV and float profile at 57.6 V bulk, 54.4 V float and 61.0 V maximum. AGM, flooded, lithium-ion and self-defined types are supported, with RS485 for BMS communication.

How does the IVPS7548 handle a weak grid or a generator?

You choose the input window. UPS mode accepts 170-280 V for sensitive electronics and appliance mode accepts 90-280 V on unstable supply, and transfer takes 15 ms in either case. It disconnects below 40 Hz or above 65 Hz, and it will not pass utility power through unless a battery is connected.

What are the dimensions, weight and installation conditions?

The unit measures 494 x 420 x 195 mm and weighs 29.1 kg net, 32.5 kg gross, packed at 607 x 540 x 290 mm. It is rated IP21, so it mounts indoors in a protected location, and it runs from 0 to 40 °C with intelligent air cooling, an LCD and LED indicators.
