Swamp, thanks I just grabbed my multimeter once I read your comment. Great, now I’ll be checking my exact voltage every morning!!! Not sure if I should say thanks lol…It was pretty cold out last night so the voltage dropped to 12.3
I’m going to order another panel for now. I’m thinking 3 100 watt panels for 2 24MDC 80ah batteries would save the in the long run!!!
The 12.3 was during a a couple cloudy days and low teens temperatures at night. I checked it this morning and it was 12.7. Last most was only 30 degrees and 42 during the day. So, the heater didn’t have to work to hard.Ooh, I didn’t mean to spread the my OCD over your way!
Sorry about that, didn’t mean to spread my OCD over your way!? What I would be looking for is to know how the batteries are holding up after a night of keeping the water warm and then seeing how well they get charged back up during the day. 12.3v is getting close to a flat 50% discharged level. I’m wondering what happens when you have a day or two of cloudy/rainy weather.
This might be a dumb question but, can I add a 1-200 watt panel to my other 2-100 watt panels?
