    Parallel LFP batteries drop voltage during absorbtion, what causes this?

    I am having a heck of a time with my bigbattery Llama's. Originally I had 3pc. They are oddball 14S batteries and charge to 51V. One of the batteries I have has a problem that bigbattery has said will be replaced after I ship it to them. There seems to be a problem causing the BMS to heat up...

    The ruling class and solar

    Am I blind or does it seem like the ruling class opt's for fancy yards instead of solar arrays? Have you ever seen a picture of member of the ruling classes property? No wind generators or solar arrays. I was shocked to see President Obama's home (very beautiful BTW). It looks like a power...

    Today the 63a output dc breaker at the combiner box tripped. The calculators I've ran on my array showed 54A max output. I saw the charge controller with upwards of 60A when i last saw it before it tripped. Is there an explanation for this that I can troubleshoot? We have 120ft of 4 awg...

    I have a MidNite Solar Classic 250 for sale. Box is unopened with brand new product. Asking $675 shipped. The reason for selling is because I needed a higher powered MPPT charge controller and ended up going with PT100 for my setup. Never opened the box. Purchased in March 2021...

    Hey everyone. I'm a new member and new off grid homesteader. Ive invested a small fortune in our solar setup and amazingly we got it up and going. Now I'm onto the parameters on the inverter/charger. I am a bit confused by the parameter spec sheet. Based on what I am reading the battery...
