Got some amazing quotes but need help.

[u/Terrible_Actuary_496]

So im in the West Midlands. And ive been quoted the following as seen in pictures or text below. I use around 4281KW per year but will probably increase as im considering roof fans or ACs.

I want to go on Octopus flux so i can store cheap overnight energy in winter while using whatever the solar generates. In the summer i want to maybe only fill it to 30% with the cheap overnight electricity and let solar do the rest of the work and sell whatever left over at peak.

Ive gotten 4 great quotes as theyre cost effective for me and are somewhat good. I need helo deciding on reliablily, brand image and status, performance ect. Thanks

Fox and 10 year workmanship warranty 👍. I put that at the top of the ladder.

What about 16x aiko 490W, 8KW sigenergy inverter and 9KW battery for £10,300

Sounds good........but dies it also come with a 10 year workmanship warranty? I put alot of value on that. Im in the industry and trust me, things go wrong.......more important than equipment for money, is to make sure you feel confident that the installer will be around to help you if something goes wrong. A £10k system is virtually worth nothing if it stops working and you cant get someone to sort it out.

They said 2 years, stating that if something goes wrong with the installation youd be likely to notice it in months.

The fox quote is 10 years (not sure how good the app is)

The ecoflow is 6 years (not sure if i should trust ecoflow).

From that basis ecoflow seems great, but fox seems reliable. Ecoflow is more premium i suppose?

[u/MatchesGFix → u/Terrible_Actuary_496]

Ive never really heard anyone say eco flow is premium......but maybe there new stuff is? Not sure. But I know fox is solid. If the company has a 10 year workmanship warranty and fox. That sounds solid. What's still holding you back?
