Hey Everyone... Just a bit of a brief backgound on the project I'm currently putting together for my Mother .. Essentially the panel and battery only has to run a small pump to keep the water moving in the pond a little bit.. Doesn't really matter how long its on/off for, I was thinking fully charge the battery and then run the pump until the battery is low and then stop the pump and charge back up kinda affair.
She wanted a small fish pond and asked me to make a water feature for it, So the setup I got for her was the following.. A 50w solar panel, 12v 90ah sealed calcium/lead acid leisure battery with no info on it whatsoever.. That was the only info I got from the Ebay seller ! And a cheap ebay 15 quid 12v 30A PWM charge controller... The load is a small 7w submersible water pump to run the water fountain in her pond...
Now the issue really is... What general recommended charge/discharge settings would you say would be ideal for this type of battery chemistry ?.. I've nothing much to go on as It was an ebay battery purchase.. Quite a lot of them sold and it cost about 80 quid or therabout's.. Actually I ordered a 50ah one and they were out of stock of them so sent me a 90ah instead.. As far as I see on the controller theres provisions for float/discharge stop/discharge reconnect
So with that being said.. What would you guys recommend for those settings ? Like at what voltage is this battery considered fully charged.. and should there be a certain percentage I can safely discharge it down to without to much stress..
As you can probably guess, I'm not up to speed on charging with a solar charge controller...
Cheers
Pat
