Manufacturer: Shenzhen Felicity Solar Technology Co., Ltd.

Application: 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.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

  • 12 V bank across a 10.5-15.75 V window: One battery input, starting the inverter at 11.5 V, with AGM, flooded, Li-Ion and self-defined profiles.
  • 40 A charging with a 14.4 V boost and a 13.6 V float: Charging voltage is capped at 16 V, drawn from a 90-280 V utility or generator supply.
  • 2 kW rated output with twice rated power for 5 s: Backup output is also rated 2 kW, single phase at 220 V on an L+N+PE connection.

Frequently Asked Questions

What battery bank does the Felicity Solar IVPS2512 need?

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.

How fast does the IVPS2512 charge a 12 V bank?

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.

How much does the IVPS2512 weigh and what does it ship in?

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.

Can several IVPS2512 units run in parallel?

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.

What battery voltage does the Felicity Solar IVPS2524 need?

24 V nominal, over a 21-31.5 V working range. The IVPS2524 starts at 23 V and charges to a 31.5 V ceiling, so the bank has to be a 24 V bank.

How fast can the IVPS2524 charge a battery?

40 A maximum charge current, and the same 40 A from the utility, delivered as a 28.8 V boost stage settling to a 27.2 V float across AGM, Flooded, Li-Ion and Self-Defined batteries.

How much does the IVPS2524 weigh and what box does it ship in?

20.7 kg net and 24.1 kg gross, in a 552 x 408 x 290 mm carton. The mass follows from the low-frequency transformer-based build.

Can several IVPS2524 units be run in parallel?

6 units in parallel. Each one is single phase at 220 V and 50/60 Hz on an L+N+PE connection, with 30 A output overcurrent protection.

What battery bank does the IVPS3524 need?

24 V nominal. The IVPS3524 works across a 21-31.5 V battery window, starts up at 23 V and takes a single battery input, with AGM, Flooded, Li-Ion and Self-Defined profiles all supported.

How fast can the IVPS3524 charge from the mains?

40 A is the maximum charge current. Charging boosts at 28.8 V, floats at 27.2 V and is capped at 31.5 V, so a 24 V bank refills without a separate charger.
