I need 24V for a shunt trip and other things and had some phoenix contact din rail fusable terminal blocks laying around. No reason other than that.

Yes. The batrium is shutdown when the breaker is off (complete shutdown).

Power to the 48v > 24v step down which powers batrium. It the shunt trips then the battery is completely turned off. There is two inline 3x20mm fuses to protect.

I am working on building an off-grid solar system for a cabin and just got my FIRST-ever battery built. I ordered 16 3.2v 280ah prismatic EVE cells from Docan Tech. They arrived from Houston, TX in excellent condition. Were charged to ~3.29v (+/- 15mv). I topped balanced with an iCharger X6 and...

I am planning an off-grid system for a cabin I am building with my partner in Southern Chile (53.1638S latitude) and am looking for some feedback. Mostly for use in the austral summer (Nov-Mar) when sun rises at 5am and sets at ~11pm. Basic specs: 48V 2380 LiFePO4 280ah battery Batrium BMS...
