I think it would be a rare for my part of NW Oklahoma to get down to -40C. Here the late fall winter, and early spring nearly always drop below the safe charging temps. The heat my batteries in are exposed to in the summer is nearing that mean old 113F. The depth of the shaft to accomplish a...

I have been working on something called a GAHT ground air heat transfer system. They tell me that six feet down the ground stays at a pretty constant 60 degrees, so I dug a circular trench to lay some thin-walled corrugated 4" poly pipe from the floor of my well house through the trench back to...

Hi you have asked an interesting question. It sounds like you are considering bypassing the SCC and going straight to the BMS thru the charge port on the BMS. I think the BMS could regulate small differences in the incoming charge, but as for my system the voltages would be too far out of range...

Me too.

I like the idea of the low temp I have a few questions. You are new to LiFePo4 batteries and so am I. So please excuse dumb questions. Your BMS C- terminal is connected to the to the neg of the SCC, and the P- terminal is connected to the neg side of your load maybe an inverter, and B-...

I was unable to set up the thermostat today, but I forgot to add that part of the plan was to supply power to the thermostat down stream from the battery fuse and down stream of the BMS ground. That is to say if the current is interrupted by a blown fuse, or a BMS interruption the lack of...

I cannot answer your question, but I am using a epever 60 amp SCC and in the installation instructions it is very clear that the battery must be connected before the panels. This instruction gave me the impression that if the panels remained connected after a BMS disconnected the battery the SCC...

I am going to try to set a thermostat to close a N/O relay at temperature when the temp is above 5 degrees C and when the cooling side reads under 4 degrees C it will allow the N/O to disconnect the relay. The relay will carry current from the solar panels to the SCC only when the temp is above...

I have been doing this for about four months now. I have been using 2- 295 watt panels my pump requires only 370 watts at 21 to 29 volts rated 24VDC. I needed to use a buck converter to use a level switch to shut down the pump if the water level went down to close to the pump. The converter...

I bought the 150A Daly BMS with separate port, and the description on the actual BMS says 80A charge current, 150A discharge current.

My BYDs are rated at 120C I bought a Daly separate port 150amp 8s LiFepo4 BMS for each of them. I hope that was proper, because it wasn't cheap.

That was my first plan, but then there was that switching idea that looked sooo good. I don't want to ruin my SCC switching from heating to batteries. So I am back to what you have just suggested, but it is nice to know I am not the only one with this idea. Thank you for sharing.

You sir are becoming a very helpful guide. I was hoping I could move the load from batteries to the load of a heat source until a thermostat told the relay to go back to batteries. Now you have me wondering if my SCC could handle the switches. I will be using an Epever 6415AN it has a temp...

I really like this idea. I was thinking I would disconnect the SCC from the batteries with a thermostatic controlled relay, but switching the power from batteries to heat would be less wasteful. Thank you for this post.
