tolerance for battery disconnects, etc

[jtdiesel65]

Hi,

I'm currently using an XW and Batrium BMS. There are no comms between them. So that's my perspective.

I was wondering how well the MN15 tolerated battery disconnects? Many folks put contactors or powered breakers between their batteries and inverters, CCs, etc that are controlled by the BMS. I was wondering how well the equipment handled events like this, say for example the BMS detects a bad cell and opens the contactor/breaker?

Ideally, you would have comms whereby the BMS could signal the MN!5 to power down, but some systems don't have that.

I use a strategy where my Conext HTTP has a lower absorb point than my two classic 150s. So the Conext drops to float while the 150s top of the battery and provide power during balancing. The arrays on the 150s get more late day sun too. For the different MPPTs, can you set different absorb points or perhaps throttle total charge power as SoC approaches 100%?

I'm trying to understand how the generator power works in the MN15. In my current set up, gen power is pass through in the XW. You essentially set how many KW to allocate to battery charging. There is no system protection in the XW, so what can happen is battery charging+house loads can overload the genset because the XW doesn't throttle back battery charging. Does the MN15 have protection for this? It sounds like maybe, but I wasn't sure.



thx!
