Atmoce launches ‘extra’ low-voltage batteries for residential PV

Netherlands-based microinverter and battery manufacturer Atmoce has unveiled new low-voltage lithium ferro-phosphate (LFP) batteries for residential applications.

“Unlike conventional high-voltage battery systems, the M-ELV Battery eliminates electrical hazards while delivering superior 90% AC round-trip efficiency, making it one of the most powerful and scalable solutions on the market,” the company said in a statement.

The IP66-rated system measures 830 mm × 480 mm × 195 mm and weighs 73.5 kg. It offers a maximum continuous input power of 3.75 kVA and a maximum output power of 5 kVa.

It features a nominal DC voltage of 26.5 V and a maximum DC voltage of 28.8 V, with the operating voltage range being 176-276 V. Its nominal battery capacity is 280 Ah and the rated battery energy is 7 kWh.

Atmoce says its new battery technology has an AC roundtrip efficiency of up to 90% and a DC roundtrip efficiency of 96%. It relies on “intelligent” air cooling and can be wall or floor-mounted.

The new product comes with a 15-year warranty and has reportedly a 10,000-cycle lifetime.

“With a modular design supporting 1-phase, 3-phase, and standalone installations, it seamlessly adapts to diverse energy needs, empowering users with a flexible, future-proof storage solution,” the company said, noting that it can be scalable to reach a capacity of 126 kWh.
