mikeman Posted March 8, 2023 Share Posted March 8, 2023 I have 4 200 watt panels going in my system.so far they are working great. My question is. Why do the batterys drop from 100% to 50% the second I turn a space heater on? But if I turn the heater off they bounce right back to 100% charged.

0 mikeman Posted March 8, 2023 Author Share Posted March 8, 2023 Can this voltage drop damage my batterys? Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 8, 2023 Share Posted March 8, 2023 I have lead acid batteries for now and they do the same thing when operating the slides. They draw up to 50 amps while moving. Once they stop they return to original voltage. Where i watch is when I have a constant draw such as the inverter usage. Once in a while I'll turn of the inverter and see where they rest. This is why I will be getting a larger battery bank with Lithium this summer. 1 Quote Link to comment Share on other sites More sharing options...
0 mikeman Posted March 8, 2023 Author Share Posted March 8, 2023 I read that passed 50% can damage lead acid. Which is what I currently have. When I turn on my heater it drops right to 50 but then bounces back to 100 if I turn it off. I just dont want to damage them. I may need a larger battery bank too. The panels keep them pretty topped off at 100% right now. Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 8, 2023 Share Posted March 8, 2023 To my kno. It's the resting below 50% that hurts them. 1 Quote Link to comment Share on other sites More sharing options...

I ask because there are many more effecient ways to heat a space on solar. Even with a monster power setup a space heater takes on average 1,500 watts continuous. I'd look into a diesel heater, use much less power and a tiny amount of fuel to keep a place toasty. Quote Link to comment Share on other sites More sharing options...
0 Kip McMillan Posted March 10, 2023 Share Posted March 10, 2023 This stand alone works really well for us. The smaller build in unit's are less but installing I hear are a pain. Look out for recalls on some brands. Quote Link to comment Share on other sites More sharing options...

If you actually look inside these units they are usually just the smaller one you are referencing inside a cabinet with the fuel tank integrated with it. Its nice because you dont have to find a separate place for the fuel to go but larger size might be a deal breaker for some like me. I have to fit my heater under the dinette seat and this unit is too tall. Quote Link to comment Share on other sites More sharing options...
