I’m getting quite confused with solar & battery used with anytime.

Is this even possible on ovo? I seem to think I might be best changing to octopus, we are looking at getting solar and a Powerwall 3 installed, we are currently using charge anytime with an indra pro and the more I look the more i’m confused if we can A: actually charge the car when excess solar, assuming we generate enough, B: use any kind of time of use tariff with anytime to charge the battery at a cheap rate C: have this battery boost addon with a Powerwall? I can’t even see battery boost any ware on my ovo page, D: Export rate prices, I think ovo will pay 12p excess for a install not done by them?

Hi ​@stead 

 

As I've said before the whole energy supply business is changing rapidly due to the introduction of huge amounts of renewable energy in the form of wind and solar and this is making it very difficult to determine what tariff is best suited to you. Unless you know you are going to be better off with the Economy 7 tariff then switching to it is not likely to be a benefit as ​@Ben_OVO said.

 

As a way forward I suggest you head over to MoneySavingExpert which is a reputable site for comparing energy costs based on your actual usage. What is key is that you put as much accurate information in as possible to get an robust comparison. Energy companies are also changing their tariffs to flex with the changing generation mix so keep an eye out for changes.

 

I'm with Octopus at the moment but I had a decade of good service from OVO before moving. I would have to say that although I have a tariff with Octopus their billing is completely haphazard and it's only my ability to track my costs that gives me confidence that I'm not going into debt. E.g. Octopus say my balance is over £600 but I know my true balance is about £200 because they haven't deducted my electricity costs for the past three months. It seems the eight-legged-one is not good at calculations. In 10 years OVO never missed a bill and never got it wrong so you need to look at other factors as well.

 

I hope you stay with OVO but you have to put your finances first.
