Possible Battery Issue
Have received some alerts from my battery monitor*. It sends, via email, an alert if the battery drops to 60% and again at 50%. The only time I’ve received these in the past have been when we are on the boat and over using the inverter.
I’ve not received any warnings for several months, but in the last couple of weeks there have been 4 warnings. The chart below shows how the voltage of the battery rises during the day (thanks to the solar panel)and then declines during the night. Up until 3 weeks ago during the day the voltage would regularly reach 14 to 14.5 volts, but suddenly this has declined to 13 to 13.5 volts (The spike at the right is when I ran the engine for a couple of hours).
I’m not sure what is happening, but suspect there may be a battery problem. I have checked the levels in each battery and topped them up. Now it’s time to wait and see what happens.
