Another DIY Powerwall in Germany (15 kWh)
#51
Would you mind posting about all you circuit breakers, shunts and so forth that you use. All the way from the panels to the batteries?
Im in Germany too so it would be good to know the units too. Kind of a headache finding ones that are conform to the regulations and blah blah blah, while also still learning about them in general.

thanks mate

Hi!

Panels -> PIP is devided into 3 strings, each string has its own DC breaker (2x 16A and 1x 10A).
PIP -> Battery 200A DC breaker
Grid -> PIP: 48A AC breaker
PIP -> Consumers: 48A AC breaker
of course, each consumer string has its own 16A AC breaker.
That's all.

best regards,
Alex

All low amp breakers are standard ABB breakers from a local hardware store.
the 200 A DC breaker is from ebay, one of these: https://www.ebay.de/itm/HQ-Sicherungsaut...SwTaVaAyUh

Hi!

No, running off grid since end of february. I'm currently even wasting quite a lot of energy by cryptocurrency mining Wink
I'm adjusting my consumption so that I don't run out of battery but also don't give away too much solar energy during the day.

best regards,
Alex

HI all.

@Chicken Could you tell me what a balancer are you used in your project on photo?
Which one do you think is better and why?
Also, give me some links for these balancers, because I have to choose one for my 15s160p project.
