In stock
Assembled from 5.12 kWh LiFePO4 modules at 51.2 V each, the system reaches 122.8 kWh of storage.
Sustains 50 kW with a peak discharge current of 125 A for demanding commercial loads.
Pairs with high-voltage battery inverters across a 500-700 V DC operating window.
Keeps dust and water jets away from the electronics in a floor-mounted cabinet.
Rated beyond 6,000 cycles to a 70% end-of-life threshold, under a stated 10-year warranty.
CAN, RS485, Wi-Fi and ETH ports connect the LCD-equipped system to monitoring.
The Deye GE-F120-2H2 puts 122.8 kWh of LiFePO4 storage behind a commercial building, workshop or large villa - enough to carry substantial loads through outages and peak-tariff hours. Its 50 kW of rated DC power moves energy quickly, while the 500-700 V operating window pairs it with high-voltage battery inverters rather than 48 V hybrids. The system assembles from 5.12 kWh modules of 44 kg each - a manageable two-person lift - and stands on the floor inside an IP55-rated enclosure that keeps dust and water jets out. When demand grows, up to 10 units run in parallel, with a stated maximum capacity of 3,600 kWh. An LCD shows status at a glance, and CAN, RS485, Wi-Fi and ETH ports connect it to monitoring. Deye states a 10-year warranty and a cycle life above 6,000 cycles to 70% of original capacity. We are an authorised Deye distributor and supply the GE-F120-2H2 from our own stock, with technical support before and after the sale.

It operates between 500 and 700 V DC, so it pairs with high-voltage battery inverters and power-conversion equipment - not with 48 V low-voltage hybrid inverters.
Up to 10 units can be connected in parallel, and the platform lists a maximum capacity of 3,600 kWh, so a site can start with one system and scale in stages.
Deye states a 10-year warranty, a cycle life above 6,000 cycles and an end-of-life threshold of 70% of original capacity.
It charges between 0 and 55 degrees C and discharges from -20 to 55 degrees C, with derating above 43 degrees; storage should stay between 0 and 35 degrees C at 15-85% non-condensing humidity.
It is a floor-mounted system in an IP55 enclosure; each 5.12 kWh module weighs 44 kg and a complete system weighs 2,090 kg, so floor loading must be checked first.
