If you have solar panels do you have islanding (essential circuit) so that they work in a power cut?

We've been quoted £2k extra for it and I'm trying to weigh up whether its worth it. Obviously with continued power cuts on the horizon its tempting to go for it but its a lot of money.

Is that to wire it in to your house or just for a socket next to your battery? Seems a lot for a single socket but less so for a full failover situation.

Its an essential backup circuit. It would mean we could use the power in our battery in the event of a power cut and would mean our panels would carry on generating more power.

it should mean we can carry on using lights, freezer etc

It doesn't sound like good value to me, unless you live in Ukraine or some other place where power cuts are expected to be frequent. I suppose if an independent socket was designed into the inverter as standard it would cost less.

OOI, what power is the emergency supply?

That's a lot cheaper than I've been priced (£10k for 12 panels & battery v £20k for similar but islanded).

TBH I'd consider it for £2k, but I'm rural and we have a number of power cuts throughout the year.

I asked about it with our new system but didn't really get an answer from the supplier. All he said was we have a socket in the inverter we can use to plug an extension cable into it.

If you know the make and model (it should be in the quotation) you should be able to look up the manufacturers brochure or specification.
