I do have a solar system at my house. I do use Trojan T-125, 3 volt batteries and do have 16 batteries installed.
The system was installed nearly 5 years ago and I can see that my batteries are reaching the end of there lifetime. The batteries doesn't keep their voltage as previously and do need refilling of battery water on a regular basis.
What I would like to know if it is possible to change to lithium batteries without much change to the system. Can I just replace the deep cycle batteries with lithium batteries
Trust to hear from you
