Manufacturer specifications

Product at a glance

High-voltage system: this battery must be matched to a compatible high-voltage inverter and the correct controller, module count and operating-voltage window. It is not a substitute for a 48V battery.

Backup time and expansion

Usable energy depends on the permitted depth of discharge, reserve setting, temperature and system losses. Your actual runtime also depends on the appliances running. Maximum discharge current limits how much power can be delivered at once; adding energy capacity does not automatically increase inverter output. Parallel or stacked expansion must follow the exact model’s instructions.

What is included

This listing covers the named battery or expressly named battery-bank configuration. An inverter, solar panels, cabinet, additional controller, cables, protection equipment and installation are included only if explicitly itemised. Phase Energy can help check the equipment schedule before installation.
