More panels or MPPT controller
Haven't been here in a while. Any suggestions are appreciated. I have had my system up for about 5 years now. It's at a cabin in northern Michigan and all in all I'm pretty happy with it. Located in a pretty wooded area I do plan on taking down a few trees to open the area up a bit more but right now I am looking to improve the system a bit. Not a lot as the current system generally meets my needs and I have a generator and charger to top off the batteries as needed but winter sun is sparse. I currently have a 12 volt system with three (3) 200 watt panels. A 45 amp PWM charge controller and a 450 amp battery bank. My question is would it be more practical to add a couple of 100 watt panels or switch to a MPPT charge controller? Thank you in advance.
