Trying to learn something new every day!
I have an existing Solar System and it has been working well for the past 1 1/2 years. It is a very basic system and was intended to be a test and light useage system in my small shop. The system contains 2-55Watt solar panels in parallel running to a cheap PWM controller then to 130 Amp lead acid battery system.
I of course have MC4 connectors and combiners as well as fuses on the solar and battery positive lines.
I want to upgrade my system now to Lithium Ion Phosphate and am not sure if I will go to 100Ah 12 Volts or 200Ah 12 volt batteries? The question I have is about the BMS to use if I start out with 4 100AH 3.2 batteries can I use a 200 or 300Amp BMS with it without any issues? I want to future protect my system in case I decide to add additional batteries going forward.
Thoughts please.
