We've had a cold snap come through this week. Got down to -10F and -5F the past two nights. I woke up to check the equipment in the shed and saw the PT-100 had F02 fault on cold night 1, and last night was F08 fault. Both times it recovered by following the instructions in the manual to reset...

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...

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...

Is there a preference when Absorb Done per the ME-ARC settings? Magnum recommended 1.5hrs for my 3p 48v bank. Bigbattery.com says absorb doesnt apply to LFP batteries in there parameter sheet and recommends 3.65v per cell for all charge stages, which is 51v for my 14S batteries. I am charging...

I got a max PV input of 4.0Kw off of my 20x 195w panels today at noon. I usually see 3.6 or 3.7 Kw as a high even on clear days. The setup is only about 2 months since it was installed. Seemed like some clouds in the sky at the time which surprised me. I have a little more confidence in...

Or perhaps I didnt size it correctly. We are off grid and have 20pc 195w panels with 345AH of LFP batteries. Now that its summer and the rainy season is here, we cant keep up with AC use in the campers on hot days where it can be cloudy. I am thinking the solution is to get another 5 panels...

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...
