Hi all,

 

I’m in the process of researching solar and a couple of installers have suggested fitting Fox ESS batteries. Just wondering if anyone has any experience with them and any feedback, negative or positive, to share?

 

In addition, can anyone explain to me about what I should be looking for in a tariff once we have the solar panels and battery installed? I do have a quote for solar from OVO so would that be a lot better than if I went with, say, Octopus?

 

Thanks in advance,

Hollie

Hi ​@Holtop , just be sure that whichever tech is fitted can work with each other. It doesn’t always.

We added batteries to our system a few years ago and have got more added since - you might want to check if what is fitted is modular and expandable.

The tariff depends as suppliers change offers from time to time. You can get an idea by thinking if you want to charge the batteries on an off peak rate to use later (useful in winter) but you might have more than you want in summer and therefore want to export any surplus.
