Manufacturer: Felicity Solar

Application: The Felicity Solar IVEM12048-11 is a 12 kVA single-phase off-grid solar inverter for a 48 V battery bank. It takes 7.5+7.5 kW of PV at 27+27 A, charges at up to 240 A from solar or AC, delivers 12 kW of backup rated power at 230 V, and weighs 26.8 kg net. That 7.5+7.5 kW of PV input is the figure that sets the -11 apart; it feeds one MPPT working from 90 to 450 V, up to a 500 V maximum PV voltage. Charging is three-stage, 56.4 V boost and 54 V float across a 42-63 V bank, and the 240 A ceiling holds from the array or from the 90-280 V AC input, which transfers in 50 ms. Output is a pure sine wave at 230 V, 50/60 Hz on L+N+PE, regulated to 5%, with 2*rated (5s) surge and 93% maximum efficiency. The IP21 high-frequency chassis weighs 26.8 kg net, ships at 28.7 kg in a 726 x 594 x 258 mm carton, parallels to 6 units and is certified to IEC 62109-1 and IEC 62109-2. We are the authorised Felicity Solar distributor and supply it with a 2 Years warranty.

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

7.5+7.5 kW of PV input power: Two PV inputs carrying 27+27 A feed one MPPT that works from 90 to 450 V, up to a 500 V maximum PV voltage.
240 A maximum charging current: AC charging reaches the same 240 A, holding 56.4 V boost and 54 V float across a 42-63 V bank at 48 V nominal.
12 kVA rated, 12 kW backup power: Delivered as a pure sine wave at 230 V single phase, 50/60 Hz on L+N+PE, regulated to 5% with 2*rated (5s) surge.
50 ms transfer on a 90-280 V input: The AC input holds from 90 V to 280 V with a 100 V start-up voltage, behind overload, over-temperature and short-circuit protection.
26.8 kg net, 28.7 kg gross: Ships in a 726 x 594 x 258 mm carton; the IP21 chassis air-cools intelligently from -10 to 50 °C and stores from -15 to 60 °C.
6 units in parallel, 93% efficiency: A high-frequency design with LCD, built-in WiFi and RS485 BMS communication, certified to IEC 62109-1 and IEC 62109-2.
60-500 V MPPT window, 60 V start-up: The single MPPT tracker wakes at a 60 V start-up voltage and tracks to the 500 V maximum PV voltage, so a long string and a short one both work.
27 A and 6 kW of PV input: Maximum PV input current is 27 A and maximum PV input power is 6 kW, giving the 4 kVA inverter room to oversize its array.
120 A charging, 28.2 V boost and 27 V float: Charging reaches 120 A from solar or from AC into a 21-31.5 V bank at 24 V nominal, held at 28.2 V boost and 27 V float.
4 kVA pure sine wave, 30 A output: Rated apparent power is 4 kVA with 4 kW backup, delivered as a pure sine wave at 230 V single phase, 50/60 Hz, up to 30 A and 2x rated for 5 s.
50 ms transfer over a 90-280 V input: Transfer time is 50 ms and the AC input holds from 90 to 280 V, with 5% voltage regulation, 30 A maximum inverter/rectifier current and overload, over-temperature and short-circuit protection.
10.4 kg net, 507 x 387 x 197 mm package: Net weight is 10.4 kg and gross weight 11.9 kg in a 507 x 387 x 197 mm package, with an IP21 rating, LCD, built-in WiFi and RS485 BMS communication.

Frequently Asked Questions

How much solar can the Felicity Solar IVEM12048-11 take?

7.5+7.5 kW is the maximum PV input power of the IVEM12048-11, drawn through 27+27 A of PV input current. The single MPPT works across a 90-450 V window up to a 500 V maximum PV voltage, and start-up voltage is 100 V.

How fast does the IVEM12048-11 charge a 48 V battery bank?

240 A is the maximum charging current, and AC charging reaches the same 240 A. The three-stage charger holds 56.4 V boost and 54 V float across a 42-63 V window at 48 V nominal, supports AGM, Flooded, Li-Ion and Self-Defined batteries on one battery input, and reaches the BMS over RS485.

What does the IVEM12048-11 deliver on the output side?

12 kVA rated apparent power and 12 kW of backup rated power, as a pure sine wave at 230 V single phase, 50/60 Hz on L+N+PE, regulated to 5%. Surge is 2*rated (5s), transfer takes 50 ms when the 90-280 V AC input drops, and maximum efficiency is 93%.

What does the IVEM12048-11 weigh, and where should it be installed?

26.8 kg net and 28.7 kg gross, in a 726 x 594 x 258 mm package. The IP21 high-frequency chassis uses intelligent air cooling, runs from -10 to 50 °C and stores from -15 to 60 °C, so it belongs indoors in a ventilated space, and up to 6 units run in parallel. We are the authorised Felicity Solar distributor and supply it with a 2 Years warranty.

What PV array does the IVEM4024-II accept?

60-500 V is the MPPT working window, opened by a 60 V start-up voltage and closed by the 500 V maximum PV voltage. The single tracker takes up to 27 A of PV input current and 6 kW of PV input power.

How does the IVEM4024-II charge a 24 V battery bank?

120 A is the maximum charging current, available from solar or from AC. The charger holds 28.2 V boost and 27 V float across a 21-31.5 V bank at 24 V nominal, supports AGM, Flooded, Li-Ion and Self-Defined batteries through one battery input, and reaches the BMS over RS485.

What does the IVEM4024-II weigh, and what is its IP rating?

10.4 kg net and 11.9 kg gross, in a 507 x 387 x 197 mm package. The chassis is rated IP21 with intelligent air cooling, operates from -10 to 50 °C and stores from -15 to 60 °C, so it belongs indoors in a ventilated space.

What does the IVEM4024-II deliver on the output side?

4 kVA rated apparent power and 4 kW backup power, as a pure sine wave at 230 V single phase, 50/60 Hz, regulated to 5% and capped at 30 A. Surge is 2x rated for 5 s, transfer takes 50 ms when the 90-280 V AC input drops, maximum efficiency is 93%, and this model is not parallel capable.

How much solar can the IVEM6048-II take?

7.5 kW. The IVEM6048-II accepts up to 7.5 kW of PV on a single MPPT tracker, with a maximum input current of 27 A, a working window of 90-450 V and a maximum PV voltage of 500 V. It starts converting from 95 V, so a short string still brings the array online.

Which batteries does the IVEM6048-II work with?

48 V nominal. The IVEM6048-II has one battery input covering a 42-63 V range, and supports AGM, Flooded, Li-Ion and Self-Defined profiles, talking to the battery management system over RS485. It boosts at 56.4 V, floats at 54 V, and charges at up to 120 A.
