With the batteries becoming increasingly unreliable, and with a battery upgrade to LiFePO4 so difficult, I decided to double the solar late last year.
This didn't help in winter or rainy days unfortunately.
It's difficult to accurately measure the capacity of batteries and so I installed a SmartShunt that was able to tell me exactly how much energy was flowing into and out of the system.
It turned out that one of the batteries was at 30% capacity and the other was 16%. Time to upgrade.
