How long will it run a fridge during an outage?

A typical fridge draws around 150W average, so the 2,048Wh battery covers roughly half a day to a day depending on cycling and temperature. Adding expansion batteries extends that proportionally.

Is the 10ms switchover fast enough for a desktop PC?

Yes for most desktop PCs and routers, which tolerate a short transfer. Sensitive servers or medical equipment may still need a true online UPS.

How much solar can it take?

It accepts up to 800W of solar input, which can recharge the battery in a few hours of good sun. Actual charge time depends on panel output and conditions.

Can I expand it later?

Yes. Add-on battery packs raise capacity to 12kWh, so you can start with one unit and grow as needs change.

Does it need professional installation?

No. It is a plug-in unit, so you connect it to a wall outlet and your appliances yourself. That is its main difference from wall-mounted home batteries.
