Note what must stay on: fridge or freezer, lighting, router, phone charging, and any medical equipment. This list, not a product label, determines the minimum size of the backup.
During an outage, comfort depends on which appliances keep running. A fridge, lighting, internet router and medical equipment ask something different from a washing machine or heat pump. Energieopslag040 maps your priorities first, then looks at continuous and peak power, and makes clear that a dedicated emergency power setup is a separate configuration — not something included automatically with every battery.

Continuous power keeps devices running for hours; peak power covers short surges such as a motor starting. Both matter, because a fridge compressor draws far more at start-up than while cooling.
Not every home battery keeps sockets powered when the grid fails. Backup output, a changeover arrangement and a dedicated circuit can be required — we quote this explicitly, separate from the battery itself.
A portable power station is quick and flexible; a fixed system with backup output carries more load for longer. Off Grid Supply, the webshop behind Energieopslag040, keeps the current models and prices — we advise which category suits your device list.
