Okay looks like it's battery voltage and there is no way to program load using solar array as variable. I can program specific times, but I already have timer switch doing it. Gonna test it out tomorrow, but hopes are not high.

These are the load setting I found. If I figure out correct ON/OFF volts, I can quicky re-wire my thermostat to SCC instead of fuse box. My 2x panels are 300w with Voc=40, Vmppt=32.83 in series (so Voc=80). Which value do I use to calculate cut off voltages? Panels should bring in more than 40w...

Is this possible? Such a solution never crossed my mind, but that most definitely would be the best way to wire it.

Mount with final paint job and turned in winter angle: Covered up my electric box: Alright, this is the final update for a while. I will answer all the questions if anyone has any. Thanks for all the help!

A beginner question - how do I charge my battery from backup generator? I hook my LiFePO4 charger to B+ and other end of BMS? And do I need to switch off my panels while charging?

Point taken. Gonna upgrade my breakers. Sadly / fortunately I'm skipping winter and heading to Philippines in 10 days, so breakers will have to wait until I'm back (could be 6+ months). Maybe can instruct someone to do it while I'm gone. https://www.aliexpress.com/item/4000662522492 - anyone...

Is there anything I should change in my LiFePO4 battery settings? I'm not sure this is how it's supposed to happen - the moment battery is full (reaching boost charging voltage at 14.4v?), SCC stops charging and voltage drops down to around 13v, just as in this picture. Anything to be...

Yeah not the first time I hear bad things about those breakers. Fuses + isolation switches seems the way to go. Anyone could link some fuse options on amazon/aliexpress/ebay? Price/performance is essential. As I mentioned, my whole system came around 1300$, so I'm not gonna put in 50-100$ fuses...

Is it okay to put cells in direct contact to heating pads? I've seen people putting metal (aluminium?) plate inbetween. And thanks, I will move my heating pads! I placed battery on the bottom for 1) easier access to inverter and other components and 2) a bit shorter wire run as it's 12v...

Thanks a lot! Thanks! Sure, here's the link (crimping isn't that great with it, but wire stripping and cutting is sweet): https://www.aliexpress.com/item/32919605118 For bigger lugs I used this hammer crimp: https://www.aliexpress.com/item/1005001908000233 I haven't fully tested it as cabin...

Electric box is pretty much done! Not 100% sure about grounding (I grounded SCC, common negative and AC panel). Not too impressed with my 20w heating pads, so added 3rd + gonna get a heat sink for them. My 2x300w panels bring in around 480w when sunny, 150w when cloudy / tree shade covering...

Aaaand we are up and running! Launch went smoothly! I have 2x300w panels in series and was pulling in 470w (clear-ish sky), which is good enough. When connected to SCC via wifi app, I came up to this setting - "Low temperature prohibits discharge temperature" which is at 0 °C by default. Is...

Small victory today! Finished wiring everything except grounding and panels, and all the lights and power sockets are working as they are supposed to! I'm quite relieved as I did all the wiring for the cabing myself and burried all the wires deep inside walls. Tried to run 900w angle grinder...

This seems like exactly what I'd need! https://www.aliexpress.com/item/1005002226494368 - roughly 30$ with shipping. I'll order 2 of those and put one in each compartment. Only concern would be it activating from heating pads, but it shouldn't happen.

Gotcha. I'm in Northern-ish Europe, so winter usually is -5 to -10 Celsius, but sometimes goes down to -20.
