Esener 2.56kWh Multifunctional 100Ah Lithium Battery

The Esener 2.56kWh Multifunctional 100Ah Lithium Battery is an energy-storage option from Phase Energy for a compatible inverter and battery system. The listed 2.56kWh is nominal stored energy, not continuous output power or a guaranteed backup duration. It can store energy for use when your system calls for battery power, within the limits of the battery and connected inverter.

Product at a glance

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.
