Hi all
I have a house with south facing rear garden in Warwickshire over looking fields with no trees.
I have access to 12V AGM 110ah batteries, cable for free all year round.
I plan to run a few panels on my roof (its about 30o) pitch and perfectly south facing, running cable into my garage with the batteries stored to charge up during the day, then in evening flick a switch to go over to running a few sockets in house off the batteries through an inverter of course.
I have also been given a 150W and an unknown panel (Chinese crap I presume) and 2 20A charge controllers, so I can start this with £0 cost so far..... bar Im going to have to buy an inverter.
Advice -
How should I connect my batteries? 48V, 24V or just singles at 12V? (I can only charge at 12V at min as have 12V charge controller, but should I go 48V inverter?)
Shall I connect them in HUGE bank? or only use as many as I think I need (Im thinking internal resistance etc...)
Where are the critical cable length issues? Is it panel to charge controller, charge controller to batteries, batteries to inverter or inverter onto ring?
Should I just change all my lights in my home to 12V and that be better then trying to use any 230V socket power for an hour or 2 each evening.
What inverter should I buy?
Anything else you can say? I know this is madness for most, but seeing as I have all this stuff for free so far and only ongoing costs would be more panels I think its of good financial sense and fun, correct?
Cheers
