First pic is for ac charger. Also I got 4kw battery with it. It's connected and it's running without any issue at moment. I'm just not 100% sure what breakers, rcd's or rcbo's is required.
Now it's connected trough B20 breaker

20A MCBs will be fine then.

Hello again. After modernisation here is my DIY system:
6 x solis 405w panels
Solax x1 3.0TD string inverter
Solax x1 retrofit 3.7kw + 4kwh solax battery
All up and running with no any issue.
Have g99 approval, now needs someone to commissioned it. MCS not really bother.

Is there anyone can help? I'm from Hull, East Yorkshire .
Thanks in advance

If it's all up and running, surely you dont need anyone to commision it do you?

How then all these reports are working? I'm sure it's need send some report to DNO by qualified electrician ? That's why I'm asking here....

OK, sorry, I wasn't sure quite what you were wanting.

Good luck

DNO just need the G99 paperwork.

It’s a new circuit so an EIC, earthing and bonding and Part P apply

Hope it’s not connected to a shared RCD

Have you got blank forms?
I still need some advice to get correct protection. At moment Inverters run on 20A breakers. They connected to DNO earth. I got earth spike and think to get connected panels to it(lightning protect).
Also, why RCD? Why not RCBO?
