Rob Sigg wrote:I wonder if I could hook up a programmable trickle charger to the battery bank so that when the panels arent charging the batteries the trickle charger will keep it above and below a certain voltage? Im only asking because the grid tie may not be an option with my provider. IM still waiting to hear from them. Besides, with only 720 watts I really wouldnt be putting too much into the grid.
Rob Sigg wrote:Right, so you got the panels going to a CC, then wiring from the CC to the batteries. Then a grid powered CC hooked directly onto the battery terminals at the same spot where the solar CC is connected. Although I think my inverter would then technically be hooked up to the grid CC as well and you are saying that wont work? Thanks!
Rob Sigg wrote:Ive attached a pic to show the idea. The CC that is run off of AC/Grid would need to be programmable so that its only charging when the voltage drops below a certain point and the array cant charge the batteries. Make sense? Is there such a CC?
Rob Sigg wrote:This wont work with a programmable feature based on voltage, the idea is to have the loads run off panels and batteries until the batteries get drained below a certain voltage, in my case probably 25.4v.
As for the storage idea, Im basically trying to do that with freezers, the problem is that even if I have them set to run during the day it wont work if its cloudy.
