Its time to rethink the battery


The OFFGEN is fitted with unique batteries that are fully serviceable and upgradeable.

The design completely removes the use of permanently bonded or fixed components useally found in a battery.

Where once you would be forced to have an ever degrading energy capability of your battery, bound to be thrown away,

now there is the OFFGEN.

Why create more waste, when you can repair.

Sizes: 5.6kWh, 8.4kWh, 11.2kWh


The Offgen by Aceleron is a compact energy storage system designed for off-grid or grid-tied residential use. While most systemsrequire additional wall-mounted components for their installation, the Offgen packs all of this in a single electrical grade cabinet (lithium-ion batteries, hybrid inverter and switch gear). This allows you to use your own PV-generated electricity or use low-tariff grid energy.

The Offgen gives you the freedom to live fully off-grid with clean energy or the flexibility to access low-tariff electricity to save money on your utility bill. Its modular design provides energy upgradable energy storage up to 11kWh.
