The ACR is a relay, not a diode. It conducts current either way. What is variable is which battery it senses to make decisions. It could be house, start, or both of them. All it does is connect at X voltage and disconnect at Y voltage. X is probably about 13.8 and Y is probably about 13.4 or so.

What size is the solar panel? Is there any load on the house bank like refrigeration etc? Is the solar panel mounted in uninterrupted sun? Is the panel performing, how many amps at peak? Has it been cloudy? Does the ACR connect in both directions? What’s the age and condition of the starting battery? The sun obviously isn’t as strong this time of year either! My 250 watt panel needs blue sky all day after September just to keep up but I am north too. Len Mitchell S/V Crazy Legs 1989 C&C 37+ Midland On.
