About the Felicity Solar IVPS2512 2kW Single-Phase Inverter / Charger

The Felicity Solar IVPS2512 is a 2 kW single-phase inverter/charger built around a single 12 V battery bank: it works from 10.5 V to 15.75 V, starts at 11.5 V, charges at up to 40 A with a 14.4 V boost and a 13.6 V float, and transfers between utility and battery in 15 ms. On the utility side it accepts 90 V to 280 V at 50/60 Hz, sinusoidal from utility or generator, and disconnects at 90 V; in line mode the output follows the input waveform at better than 95% efficiency, while conversion peaks at 90% and output regulation stays within 5%. Backup output is rated 2 kW, with twice rated power for 5 s. Protection covers over charge, over discharge, overload, output short circuit and over temperature, with a 30 A output overcurrent limit and air switch protection. At 21 kg net and 24.4 kg gross, this low-frequency, transformer-based build ships in a 552 x 408 x 290 mm carton. We are an authorised Felicity Solar distributor and supply the IVPS2512 from our own stock.

Frequently Asked Questions

12 V nominal, through a single battery input. The IVPS2512 works between 10.5 V and 15.75 V, starts up at 11.5 V, and accepts AGM, flooded, Li-Ion and self-defined battery types.

40 A maximum charge current. Charging boosts to 14.4 V, floats at 13.6 V and is capped at 16 V, taken from a 90-280 V supply at 50/60 Hz that may be utility or generator.

21 kg net and 24.4 kg gross, in a 552 x 408 x 290 mm carton. That mass follows from a low-frequency, transformer-based topology, air cooled, rated IP21 and covered by a 2 Years warranty.

Up to 6 units. Each carries an RS485 BMS link and an RS232 port, an LCD and LED display, 30 A output overcurrent protection, air switch overload protection and a 0-40 °C operating range.
