Models Covered: IVEM3048-LV, IVEM5048-LV

Manufacturer: Shenzhen Felicity Solar Technology Co., Ltd.

Application: The Felicity Solar IVEM3048-LV is a 3 kW single-phase off-grid inverter on a 48 V DC bus, working across a 42 V to 63 V battery range. It combines mains or generator input, a built-in MPPT solar charger and a 110 V pure sine wave output for off-grid and backup power. Its single MPPT tracker runs from 120 V to 450 V, starts at 125 V and takes up to 4 kW of PV at 15 A on one string. Solar and AC charging each reach 60 A into AGM, flooded, lithium-ion or self-defined banks, with RS485 BMS communication and three-stage charging at 56.4 V bulk and 54 V float. Transfer takes 10 ms in UPS mode over 90-140 V, or 20 ms in appliance mode over 65-140 V, and mains passes through with no battery connected. Line-mode efficiency is above 95%, peak inverter efficiency 93%, and twice rated power for 5 s starts motor loads. The wall-mounted IP21 chassis measures 440 x 328 x 130 mm at 11.9 kg net, with intelligent air cooling, an LCD, built-in WiFi and IEC 62109-1 and IEC 62109-2 safety standards. Parallel operation is not supported. We are an authorised Felicity Solar distributor.

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.
