Felicity Solar IVPS3524P1G1-LV 2.8kW Single-Phase Inverter / Charger features

2.8 kW at 110-127 V

Rated output is 2.8 kW single phase, with the same 2.8 kW held on the backup output as a pure sine wave regulated within 5%.

80-140 V input window

Appliance mode accepts 80-140 V and only disconnects at 80 V, reconnecting at 85 V; UPS mode narrows the window to 90-140 V.

40 A three-stage charging

Charges a 24 V bank operating from 21 V to 31.5 V at up to 40 A, holding 28.8 V bulk and 27.2 V float across AGM, flooded, Li-Ion and self-defined types.

15 ms transfer, 2x surge

Transfer time is 15 ms and the unit carries twice rated load for 5 s, which is what starts a motor without stalling the output.

Eight units in parallel

Up to 8 units run in parallel, with an RS485 BMS link, RS232 and RS485 interfaces and an LCD plus LED display.

27.7 kg net, 440 x 391 x 195 mm

Net weight is 27.7 kg and gross 30.8 kg in a 552 x 508 x 290 mm carton; the IP21 chassis is air cooled for 0-40 °C operation.

About the Felicity Solar IVPS3524P1G1-LV 2.8kW Single-Phase Inverter / Charger

The Felicity Solar IVPS3524P1G1-LV is a single-phase inverter/charger rated 2.8 kW, holding the same 2.8 kW on its backup output. It runs a 24 V battery bank between 21 V and 31.5 V, puts out 110-127 V at 50/60 Hz on an L-N connection, accepts 80-140 V from utility or generator, and transfers in 15 ms. The -LV suffix is written into those AC figures: nominal input is 110-120 V, the appliance-mode window runs 80-140 V, and the unit holds on down to 80 V before disconnecting, reconnecting at 85 V, so a soft 120 V supply keeps feeding loads. UPS mode tightens the window to 90-140 V. Charging is three-stage - boost CC, boost CV, float - at up to 40 A, 28.8 V bulk and 27.2 V float, across AGM, flooded, Li-Ion and self-defined banks, with a BMS link over RS485. The low-frequency transformer build weighs 27.7 kg net, starts motors, carries twice rated load for 5 s, and parallels to eight units. An overcurrent protector handles overload, alongside over-charge, over-discharge, output short-circuit and over-temperature protection. Warranty: 2 Years. We are an authorised Felicity Solar distributor and supply the IVPS3524P1G1-LV from our own stock.

Frequently Asked Questions

2.8 kW, single phase, and the same 2.8 kW stays available on the backup output. The waveform is a pure sine wave at 110-127 V and 50/60 Hz, regulated within 5%, and the unit carries twice rated load for 5 s to start motors.

24 V. The bank works anywhere from 21 V to 31.5 V on the single battery input. AGM, flooded, Li-Ion and self-defined types are supported, charged in three stages - boost CC, boost CV, float - at up to 40 A with 28.8 V bulk and 27.2 V float. It starts at 23 V and talks to a BMS over RS485.

80-140 V is the appliance-mode input window, so it holds on until 80 V and reconnects at 85 V; UPS mode uses 90-140 V. Input may be a sinusoidal utility or generator waveform at 50/60 Hz, and switching to battery takes 15 ms.

27.7 kg net and 30.8 kg gross. The unit measures 440 x 391 x 195 mm and ships in a 552 x 508 x 290 mm carton. It is a low-frequency, transformer-based build rated IP21 with intelligent air cooling, for 0-40 °C operation and -15 to 60 °C storage.
