Il Sig Sterling (in arte Mark Grasser - USA) mi ha già risposto - sò pporpio ammericani -. Lui è assolutamente per un unico pacco batterie servizi, sia che tu abbia 1 batteria o che tu ne abbia 4 o 6; lui è per tutto in parallelo e tutto sempre a disposizione per le utenze. Con questo approccio non ci si deve porre il problema di un pacco più scarico dell'altro, si scarica tutto nello stesso modo (anche se comunque non sempre è così, dipende da come sono fatti gli impianti). In luogo di un pacco servizi di riserva lui pacificamente dice 'tieni unico pacco servizi e prenditi un sistema per controllare lo stato di carica delle batterie e risolvi il problema'. Pragmatico ma sicuramente 'make sense'.
Voi cosa ne dite?

Marco,
If you separate the house bank into two banks of 2 batteries each and then drain them down separately they will not be at the same discharge level but you then want to charge them all at the same time. Why do you do this. If you keep all of the 4 batteries connected as one bank and use it the same amount as two separate banks do you not use the same amount of amp hours total? Personally I do not like battery switches that separate banks. For instance it will allow you to connect a fully charged bank to a dead bank. This will make close to 1000 amps to be dumped from the good bank to the dead bank with possible fire as the result.
I have always been for one single house bank with no switches for the operator to play with. Worse yet for a guest to play with. Using one house bank with one AtoB should be all you need. “IF” you want to have more understanding of where the charge level of your batteries are at any time I would suggest that you install an amp-hour counter such as our PMP1. If properly installed you will be able to watch the amount of discharge and then the amount of re-charge to the bank. This way you can see when the bank reaches 50% discharge and then start the recharge process.
Sincerely,
