Re: 12V circuit breaker for small photovoltaic installation
Circuit breakers for alternating current are not suitable for direct current. The A/AC/HPi type concerns the differentials, not the circuit breakers... In short, Remundo's answer is correct, a circuit breaker for 1000V direct current will operate at 12V direct current. A circuit breaker for alternating current...

Re: Parallel and/or series connection (beginner)
No as presented the 4 are short circuited. But not having understood the author's intention at all, I refrained from commenting. I don't know why, but I have a feeling that we're going to spend weeks talking about these panels and ultimately won't do much. Reflected...

Re: My little stay in Brittany from October 28.
Okay, this is definitely the future. Because cold cassoulet shouldn't be terrible..., if you can avoid it. At home I always make a point of keeping a low-tech solution in working order. In 1999, despite a week without power, we didn't feel cold because...

Re: My little stay in Brittany from October 28.
And with V2L tending to become more widespread (it wasn't available on mine when I bought it) if your battery is charged, you still have a few days of autonomy to power essential things. Otherwise you need to have a generator available but you also need to have fuel in reserve...

In 1999 we went 7 days without electricity.

Re: 12V parallel and series solar panel connection (beginner)
Your thing being limited to 20A (output) so 240W at 12V, it doesn't really make sense to put 4 panels of 180Wp (so 720Wp in total) on it. As for putting 8, it's clearly a waste. Certainly it can be useful in case of weak sunlight, but at the slightest ray of sunlight the...
