I’m working all day everyday on the boat. I should have the engine ready to start by the end of the day. I’m trying to figure out an issue with my house battery. It’s either the battery or solar panel. The issue is the solar panel has 100% charged my starter battery and both are connected with an ACR. When I put my multimeter onto my house battery when the panel is charging it, I can get 14+ volts. But when I disconnect the panel I get around 12.0v which is almost totally discharged. The starter reads 13v when not charging. I bought them both at the same time and the water levels are good. The house battery has held a charge for a long time previously. Also my inverter charger is hooked up to my house battery and it says the state of charge is around 75%, which conflicts with my multimeter reading.
Today I’m gonna charge both batteries with shore power and see if the house battery holds a charge. I will probably either have to buy a new house battery or add another 50w of solar power.
I have to finish buying food for the trip and I have to clean up. I have to finish wiring my mast lights, stern light, and nav lights. Right now I’m expecting to leave on Monday morning.
