Can I connect two 12 volt charge controllers to my 400 watt solar array?
I presently have a 12 volt 40 amp MPPT controller connected to a 12 volt 200 Ah lithium ion battery. I would like to connect a second 12 volt, 30 amp MWP charge controller that I have purchased and connect it to the same solar array in parallel and power two AGM batteries.
I hope this makes sense. I want to charge the second battery bank AGM separate from the lithium ion battery for obvious reasons (as you know, lithium ion doesn’t require a float etc.).
