I was going to say I’m surprised you don’t have a small genny Paul, just for contingencies. But I guess the local internet and the mobile relay depend on the island’s power, so while your own supply would stop your freezer defrosting you’d still need a sat phone to get a message to the outside world (OK, semaphore would work, but not for contributing to the lovely cricket thread).
The Gateway box can also isolate your house from the mains if there is a power cut (required so that power isn’t fed back down the line in order to not electrocute people doing maintenance if you have solar microgeneration).
Tbh, it’s only the TV (when there’s live sport on) and internet that is an issue. I have two camping gas powered hobs for cooking and plenty of oil lamps and candles for light. It’s not that regular that it warrants such an investment.
Besides, it would only work effectively in the Summer when it isn’t an issue. In Winter (when it may be of some benefit) I suspect it wouldn’t get sufficient charge to be effective.
It can be charged from the mains to be a backup supply as well as storing from microgen, but then a bit of indoor camping seems to be part of the island lifestyle…
This is one of the limits of PV* in countries like the UK, where the summers are fine but the winters can be cold. It works much better in places where the big demand is for powering summer air-con.
