AC-integrated utility-scale storage system in a 20 ft container: 6.25 MWh with integrated PCS (690 V grid voltage) and up to 1.72 MW of output power in the 4-hour variant. Unlike the L3.7 and L5.0 DC blocks, the L6.25 connects to the medium-voltage transformer directly on the AC side.
Frequently asked questions
What is the PotisBank L6.25?
An AC-integrated utility-scale storage system in a 20 ft container with 6.25 MWh, liquid-cooled LFP cells and an integrated PCS.
How much power does the system deliver?
Up to 1.72 MW of output power in the 4-hour variant at 690 V AC.
What does AC-integrated mean?
The PCS is already integrated in the container — the connection is made on the AC side at 690 V.
What are the safety and enclosure features?
Sprinklers, a fire alarm system and gas detectors per NFPA 68/69 (aerosol optional), with IP55 / Type 3R protection. The container measures 6,058 × 2,438 × 2,896 mm and weighs around 48 t.
