About the Felicity Solar IVPS5024 4kW Single-Phase Inverter / Charger

The Felicity Solar IVPS5024 is a single-phase off-grid inverter-charger rated 5 kVA apparent and 4 kW real output, drawing from a 24 V battery bank and producing a pure sine wave at 220 V, 50/60 Hz. A 50 A charger and low-frequency transformer topology make it a fit for motor-driven loads. Because the design is transformer-based, the unit is motor-start capable and carries a 2x rated surge for 5 seconds, so pumps and compressors start without nuisance tripping. AC input is accepted from 90 V to 280 V in appliance mode, with a tighter 170-280 V UPS window for sensitive electronics, and transfer takes 15 ms. Battery support covers AGM, flooded, lithium-ion and self-defined profiles, with RS485 BMS communication and a three-stage boost CC, boost CV and float algorithm working between 21 V and 31.5 V. Up to six units operate in parallel. The unit measures 494 x 420 x 195 mm, weighs 29.1 kg net, and is rated IP21 with intelligent air cooling. We are an authorised Felicity Solar distributor and supply the IVPS5024 from our own stock.

Frequently Asked Questions

What is the output power of the Felicity Solar IVPS5024?

It is rated at 5 kVA apparent power and 4 kW real output, single phase at 220 V and 50/60 Hz, with a pure sine wave waveform. Backup rated output power is also 4 kW, and the unit tolerates twice its rated load as a surge for 5 seconds.

What battery voltage and battery types does the IVPS5024 support?

It runs on a 24 V nominal battery bank, operating between 21 V and 31.5 V and starting up at 23 V. It supports AGM, flooded, lithium-ion and self-defined profiles, with RS485 BMS communication and a three-stage charge algorithm at 28.8 V bulk and 27.2 V float, up to 50 A.

How quickly does it switch to battery, and what AC input does it accept?

Transfer time is 15 ms. AC input is accepted from 90 V to 280 V in appliance mode and from 170 V to 280 V in UPS mode, with up to 63 A of pass-through current. The IVPS5024 does not pass through utility power without a battery connected.

What are the physical specifications of the IVPS5024?

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 with intelligent air cooling, an LCD and LED display, and an operating temperature range of 0 to 40 C.
