75/15 MPPT: Using 1 switch EACH to A) Turn off solar before disconnecting battery (to prevent surge) and B) Disconnect battery to prevent 30mA SolrCtlr battery discharge.
Can I do both with 1 SPST switch to disconnect BOTH BattyNeg and SolarNeg? They appear to be connected per my ohmmeter.
I suspect I'm overthinking this and may not need the switch to prevent battery disconnect surge at this low amperage.
BTW, this is important to my RV customers -- 1 switch would make this MUCH SIMPLER! Thanks!
