Since the major rewire of battery leads. The batteries had died and I assumed that this was because of the effects from the short circuit accident last summer. So a few weeks ago I had renewed the batteries. Since then I have noticed a steady decline in capacity. It’s not unusual to struggle for charge from Solar in the winter because of the lack of sunlight hours but the rate of drain is too fast and I suspect the Solar Charge Controller.
I changed the solar charger once before when the same symptoms occurred. Having done some research on solar setups, this time I’m upgrading to a MPPT controller. I settled on a Renogy Rover Unit and fitted this the other day. Apart from making a new mounting bracket this was essentially a straight swap in terms of wiring but saw an immediate improvement in charge rate.
Happy Days!

Great job. I fitted a Victron MPPT controller a couple of months ago and it seems to do a great job and keeps my batteries well charged even over the winter. I’m sure you have already thought about the issue of shade from superstructure or surrounding boats but I’ve seen some YouTube coverage that it does make a difference as to whether you wire up you panels in series or parallel.. good luck with your preparations.
