Charlie, I will add to Edd’s post. I have a different system and would suggest you find the closest place to connect to power. Battery, battery switch, ACR or other. You need to make sure the connection is solid, fused and that the wire is appropriately sized. I am running a power share relay/monitor system of 90s vintage that works like an ACR. I have a 250 watt panel on Davits. I never plug into shore power and have been running solar in two boats for more than 20 years without any problems. I have 4 deep cycle golf cart batteries and a 12 volt inverter only battery, (no dedicated start battery). The ice box fridge freezer runs May to September. There is probably a “best” location to connect but this works for me worry free. My battery bank is in the share mode before I make morning coffee unless it’s raining of course. There is an added bonus that batteries seem to last many years this way and mine are connected 24/7/365. As a side note anyone doing any wiring on a boat should also consider fusing the positive battery leads. Len Mitchell Crazy Legs 1989 37+ Midland On.
