I mounted my controller and breaker box today, got the Communication cables ready to run to the remote panel and one to the router for computer access.
I checked the batteries that were low on electrolyte and found a few cells that showed weak, and bad. Turned out the three 6 volt batteries were about 4 years old, three others showed 100% and they were just 2 years old.
I bought 3 new ones today.
Here is a slide show on the batteries and the pricing on them for your info.
