Hi. I am looking to do a van conversion with solar. Due to high energy demands, I have separated my electrical equipment into two groups - what I consider important (such as lighting and refrigeration) and less important (such as a television). Because of this, I would like to have a separate bank of batteries for both groups.
All I am wanting is a setup where the charge controller will charge the main bank first, then when it is full, to switch to the second bank (similar to how a home system would automatically switch to sending to the grid). This way, I get the luxuries only when the important equipment is taken care of.
All the research I have done so far offer either
1. Setups (normally with diodes) where the charge is sent to the bank with the lowest capacity and switching back and forth, charging both equally.
or
2. A manual switch where you select bank 1, 2 or both.
I cannot seem to find any setup to achieve what I am wanting. I am sure it is just me missing it, but google doesn't seem to like my searches anymore!
As you can probably tell, I am pretty new to this - I am really hoping the answer is not too complicated. I really appreciate any advise / pointers you can give.
Many thanks,
Mark
