This should help with power cuts. 4x 240V sockets, 4x USB sockets (plus free x3 AC adapter), charges from mains or our petrol generator (~1hr), or the car 12V socket (slower), and will take up to 1kW of solar input.

Will run LPG boiler for days on a charge, so heating and hot water covered. Fridge/freezer covered for at least a day. Microwave for about 45mins per charge, TV and Xbox for long enough to watch a film.

Plus useful for J's remote art stuff, running a PA system or projector.

Plus it will pick up fast enough (10ms) to probably work as a UPS for computers or 3D printers. They don't guarantee it for medical devices, but say "check with the manufacturer". So yeah, probably for something like a positive pressure machine or insulin fridge.

The one feature I doubt I'll use is the app (not a fan of connecting hardware to the net if not necessary), but it allows you to remotely/monitor/turn off outputs.

@_thegeoff 10ms pick up is more than fast enough for computers or anything else with a switched mode power supply - they generally survive visible (lights dropped out for a moment - 100ms) power blips. Not guaranteeing medical devices is legal - they don't accept the legal costs if you are injured from an incompatibility with their inverter's imperfect sine curve.
I've had similar with a square wave can inverter "not suitable for computers" - fine for laptops.
