Manufacturer: Shenzhen Felicity Solar Technology Co., Ltd.

Application: The Felicity Solar IVPS10048P2G1 is a 48V off-grid inverter and charger rated 10000VA and 8000W, holding a 20000VA surge for 5 seconds and charging a battery bank at up to 80A. It gives split-phase 110/120Vac±5% between HOT1-N or HOT2-N, regulated to ±5%rms, and transfers between utility and battery in 15ms (typical). Utility charging accepts 90-280Vac, disconnecting at 170±7Vac (UPS) or 90±7Vac (APL) on the low side and 280±7Vac on the high side; output is a pure sine wave and synchronises with input voltage in line mode. Battery settings cover 57.6V boost and 54.4V float on AGM, 58.4V and 55.2V on flooded, and 61.0V maximum on lithium, starting from 46V and shutting down at 43Vdc below 50% load. Peak efficiency is 90%, a 63A overcurrent protector guards the grid side, and the unit does not pass utility through without a battery. It measures 584 x 420 x 195 mm, weighs 67.7 kg gross and runs from 0°C~40°C. We are an authorised Felicity Solar distributor and supply the IVPS10048P2G1 from our own stock; warranty 2 Years.

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.

48V nominal DC, charging at up to 80A and regulated across 0-80A. It starts from 46V, alarms at 46Vdc below 50% load or 44Vdc at 50% load and above, and shuts down at 43Vdc / 42Vdc. Lithium charging tops out at 61.0V; AGM boost is 57.6V and float 54.4V.

What are the dimensions and weight of the IVPS10048P2G1?

584 x 420 x 195 mm and 67.7 kg gross. Packaged it measures 670x470x355mm. The unit operates from 0°C~40°C and is stored between -15°C~60°C.

Can the IVPS10048P2G1 charge from a generator or an unstable grid?

90-280Vac is the accepted utility charging range, and the input waveform is sinusoidal from utility or generator. Nominal input is 220Vac at 50Hz/60Hz, transfer takes 15ms (typical), a 63A overcurrent protector guards the grid side, and the unit does not pass utility through without a battery connected.

What output power does the IVPS3524P1G1-LV deliver?

2.8 kW, single phase, and the same 2.8 kW stays available on the backup output. The waveform is a pure sine wave at 110-127 V and 50/60 Hz, regulated within 5%, and the unit carries twice rated load for 5 s to start motors.

What battery does the IVPS3524P1G1-LV need?

24 V. The bank works anywhere from 21 V to 31.5 V on the single battery input. AGM, flooded, Li-Ion and self-defined types are supported, charged in three stages - boost CC, boost CV, float - at up to 40 A with 28.8 V bulk and 27.2 V float. It starts at 23 V and talks to a BMS over RS485.

Will the IVPS3524P1G1-LV run on a weak 110 V supply or a generator?

80-140 V is the appliance-mode input window, so it holds on until 80 V and reconnects at 85 V; UPS mode uses 90-140 V. Input may be a sinusoidal utility or generator waveform at 50/60 Hz, and switching to battery takes 15 ms.

How much does the IVPS3524P1G1-LV weigh and what size is it?

27.7 kg net and 30.8 kg gross. The unit measures 440 x 391 x 195 mm and ships in a 552 x 508 x 290 mm carton. It is a low-frequency, transformer-based build rated IP21 with intelligent air cooling, for 0-40 °C operation and -15 to 60 °C storage.

What is the rated output power of the IVPS5048P1G1-LV?

It is rated at 4 kW of output power, 5 kVA apparent, on a single phase, and its backup rated output power is also 4 kW. The low-frequency, transformer-based design carries twice rated load for 5 seconds, and the unit is motor-start capable.

What battery does the IVPS5048P1G1-LV run on, and how fast does it charge?

Nominal DC input is 48 V, with a working battery range of 42-63 V and start-up at 46 V. Charging is three-stage - boost CC, boost CV, float - at up to 50 A, with 57.6 V bulk and 54.4 V float and a 61.0 V maximum. AGM, flooded, lithium-ion and self-defined profiles are selectable, and BMS data runs over RS485.
