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.

Frequently Asked Questions
What is the rated output power of the Felicity Solar IVPS7548?
It is rated 6 kW of real power and 7.5 kVA apparent, single phase at 220 V and 50/60 Hz, with a pure sine wave output. The low-frequency design carries twice rated power for 5 seconds, so motor loads such as pumps and compressors start without tripping the inverter.
Which battery bank does the IVPS7548 need?
A 48 V bank. It operates from 42 V to 63 V, starts up at 46 V, and charges at up to 60 A through a three-stage boost CC, boost CV and float profile at 57.6 V bulk, 54.4 V float and 61.0 V maximum. AGM, flooded, lithium-ion and self-defined types are supported, with RS485 for BMS communication.
How does the IVPS7548 handle a weak grid or a generator?
You choose the input window. UPS mode accepts 170-280 V for sensitive electronics and appliance mode accepts 90-280 V on unstable supply, and transfer takes 15 ms in either case. It disconnects below 40 Hz or above 65 Hz, and it will not pass utility power through unless a battery is connected.
What are the dimensions, weight and installation conditions?
The unit measures 494 x 420 x 195 mm and weighs 29.1 kg net, 32.5 kg gross, packed at 607 x 540 x 290 mm. It is rated IP21, so it mounts indoors in a protected location, and it runs from 0 to 40 °C with intelligent air cooling, an LCD and LED indicators.
