Re: Need advice about backup (prepper) solar charge controller to convert Grid Tie panels to batties
Fixed typo below (0.030 is "correct") -BB Flooded Cell Lead acid batteries are pretty forgiving as long as you program the correct voltages, do not over discharge, fully charge at least onc…1 · -
Re: Mixing different panels in parallel
The reason that Photowhit says that if the array voltage is "too low" (Vmp-array) is because: * Solar panel labels are based on standard test conditions. A "flash" simulated sun f…2 · -
Re: Newbie Off Grid Design Florida
If you can live with "daytime only solar pumping", there are some very nice pumps out there. Here is an example (there are many more) of one that will work from solar, batteries, and even A…1 · -
Re: Newbie Off Grid Design Florida
Off Grid Solar is not cheap... Typically around $1 to $2+ per kWH (for full time off grid--For a few weeks a year backup, a large off grid solar system is not even in the ball park, cost wise) vs wha…2 · -
Re: Can a 12/24v solar panel charge a 48v lithium batery
In general, most solar charge controllers need the solar array Vmp-array to be a higher voltage than the battery bank charging voltage (MPPT controllers are typically "buck mode" or voltage…1 ·
