Re: [Amel Yacht Owners] Charging / Discharging issue

How were you measuring the battery capacity? Are you using a built-in battery monitor? I wonder if there could be something wrong with that. What did it show for the charge current when you were running the 100A charger? What about the charge current when the solar and wind were going? What was the current draw from your electronics?
Are you sure all of the batteries are connected? Check the connections, and also check any battery terminal fuses that may be installed.
It would be worth a sanity check with a multimeter to verify the voltage at the battery bank is what the monitor claims (and you can also use this voltage with some tables you'll find online to estimate the state of charge, if there is no load/charger on the bank when you took the measurement). You can also use your multimeter to measure the voltage across the shunt resistor used by the battery monitor; with the shunt's resistance (should be printed on it) and Ohm's law you can verify the current flow.
