Notes to the specifications

Voltage suitable for various high DC voltage inverters. Please enquire with Freedom Won for pairing support.
Max current duration 2 min every 10min. 1.5 x Max overload can be handled for 5 seconds. Current limits rated for 10°C to 25°C battery temperature. Derating will apply outside this temperature range.
These dimensions do not include the isolation panel on the side. Power supply and isolation panel dimensions H x W x D [mm] 930x440x370mm. Isolation panel door opens towards the front face of the megaTower. Isolation panel can be mounted either side of the megaTower.
Refer to warranty document for further details.
Isolation panel requires 220VAC to ensure the backup batteries are charged and balanced.
