City dwellers in PLS at the slightest power outage.
In 1999 we went 7 days without electricity.

Are you competing for the World Topic Digging Championship?

That's about the only true thing in all this gibberish...

Yeah and well, the Alpes de Hautes Provence is not the Creuse, the Jura or the Ardennes...
Winter temperatures and sunshine are not necessarily comparable.

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...

There are no losses with a 3-way valve, we take from the stock only the energy necessary to obtain the set temperature.
And there is no need for 2 circulators, just 1 is enough... but it still needs to be placed in the right place in the circuit.

What is the Voc voltage of your panels?
Because since your regulator supports up to 100V, the simplest thing is still to put the 4 in series (if the Voc of the panels does not exceed 25V).

Forhorse: You didn't read me correctly: the 6mm2 would not be over a distance of 20m but less than 5 from the Bar Bus which would be powered by a copper cable capable of passing 500 to 750A (typically a starter cable well made of copper). To pass 500A, just over 5m, you need a plastic cable...

To supply 12V to a 60W device (your TV) at 20m while accepting a 3% voltage drop, you already need a 6mm² copper cable. This debate has already taken place hundreds of times, and each time the conclusion is the same. Except in a "tiny house" for a few marginalized people, in a m...

Lots of chatter to finally say shit... and no doubt another margoulin who comes to sell wind.
