    Solar and battery storage

    I've been solar charging my MG5EV for the last 6 months using a cheap bank of 16 leisure batteries, works well. 18 250w ex-farm panels £50 each and a hybrid 5kw/10kw burst charge controller / inverter. Generates about 15-20 kw/h per sunny day, runs the car and the house so I only pay a standing...

    Direct Solar PV to HV charging?

    Yes I'll definitely consider a 48v system to keep the current draw on the batteries down, however the idea is more around charging during sunlight whilst the panels are producing significant power, in which case the batteries are mainly being used as a voltage stabiliser for the inverter running...

    Direct Solar PV to HV charging?

    After much research I've actually decided to take the battery and inverter route. I can get 8 x 100a/h car batteries for around £500 ( 2 parallel banks of 4 in series = 24v @ 400a/h) and a 3kw (6kw surge) 24v pure sine wave inverter for another £200, which is a lot cheaper than a comparable...

    Direct Solar PV to HV charging?

    I have a spare 10-panel array of solar panels that in series will give approx 360v DC / 2700w maximum output in direct sunlight. I'm looking into using them for a stand-alone solar charging system but it seems pretty inefficient (and expensive!) to use storage batteries and inverters as there...
