Felicity Solar IVEM12048-11 12kW Single-Phase Off-Grid Solar Inverter features

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.

About the Felicity Solar IVEM12048-11 12kW Single-Phase Off-Grid Solar Inverter

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.

Frequently Asked Questions

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.

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.

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%.

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.
