Choosing expansion batteries and accessories

Expansion batteries, cables and connection equipment are made for specific models. An expansion battery adds stored energy (watt-hours) to a compatible power station; it does not raise the station’s output limit (watts).

Transfer equipment, such as a transfer switch or a power inlet with an interlock, connects a station to selected home circuits and keeps it isolated from the utility grid. It must be installed by a licensed electrician and may require a permit.

Choose with more clarity.

Does an expansion battery work with any power station?

No. Expansion batteries are designed for specific models and connectors. Check the compatible models on the product page; if your station is not listed, contact us before you buy.

Does an expansion battery increase output?

No. It adds stored energy, so the station can run the same loads for longer. Continuous and surge output are set by the station itself.

Do I need a transfer switch to power home circuits?

To power hardwired home circuits, you need approved transfer equipment installed by a licensed electrician. Never connect a station to a wall outlet to feed the home: it can energize utility lines and endanger line workers.
