About the Felicity Solar IVPM5048 4kW Single-Phase Off-Grid Solar Inverter

The Felicity Solar IVPM5048 is a single-phase, low-frequency off-grid inverter-charger that delivers 4 kW of rated output and 5 kVA of apparent output at 220 V, 50/60 Hz, from a 48 V battery bank. Its one built-in MPPT tracker takes up to 6.6 kW of PV within a 65-145 V window, 170 V maximum. Solar charging reaches 120 A and utility charging 50 A, in three stages - boost CC, boost CV, then float - at 57.6 V boost, 54.4 V float and 61.0 V maximum. Efficiency is 95% in line mode and 90% at best in inverter mode; transfer between utility and battery takes 15 ms, and the IVPM5048 holds twice its rated output for 5 seconds so pumps and compressors start cleanly. Batteries may be AGM, Flooded, Li-Ion or Self-Defined anywhere in a 42-63 V window, with RS485 to the battery BMS and RS232 for monitoring behind an LCD and LED panel. The cabinet is IP21, intelligently air-cooled, 494 x 420 x 195 mm and 36.3 kg net, and up to 6 units run in parallel when a battery is present. We are an authorised Felicity Solar distributor and supply the IVPM5048 from our own stock; warranty is 2 Years.

Frequently Asked Questions

Can the IVPM5048 charge batteries directly from solar panels?

Up to 6.6 kW of PV: the IVPM5048 has one built-in MPPT tracker working between 65 V and 145 V, with 170 V maximum PV voltage and up to 120 A of solar charging current into the 48 V bank.

How fast can the IVPM5048 charge from the grid?

50 A is the maximum AC charge current. AC input is accepted from 90-280 V in appliance mode or 170-280 V in UPS mode at 50/60 Hz, and pass-through current is rated 63 A.

What battery bank does the IVPM5048 need?

48 V nominal, usable from 42 V to 63 V. AGM, Flooded, Li-Ion and Self-Defined batteries are supported, charged in three stages - boost CC, boost CV, then float - at 57.6 V boost, 54.4 V float and 61.0 V maximum, with RS485 to the battery BMS.

How much does the IVPM5048 weigh and how many units run in parallel?

36.3 kg net and 39.7 kg gross; the unit itself measures 494 x 420 x 195 mm and ships in a 607 x 540 x 290 mm carton. Up to 6 units run in parallel, and a battery must be connected.
