Just a few Quick Question's, regarding Capacity and Pack Protections
#11
so in my last test i lost 6 batteries cause the 24V inverter Alarms to late and a test pack 7s2p was drained below 3.0 on 3 of the 7 strings so had to throw out 6 batteries after the test cause they got triggered internally and popped something internally, not going to try to fix the cell,

would love for the watchmon when it senses a Cellmon with a Low Voltage level, trigger an External Relay to cut Voltage to the inverter.

I guess the user cant alter the cease inverting voltage on those budget inverters ?

The link provided previously details how to configure the WM to open or close relays and breakers, based on cell or pack voltage.

I'm not sure i understand how the link you shared shows how to do Low Voltage or Over Voltage Cutoff,

the link you shared showed how to hook a circuit trip to either the positive or negative sense. which would not that i know of help unless i'm more ignorant that i thought i was, but please if you can explain is a little more detail how those two concepts intertwine i'm sure i'll be able to figure it out...

If you read all of the "how to" documentation produced by Batrium it will become clear how you configure the WM logic, in association with a trip, to achieve low and /or over voltage cutoff.

I'm more than happy to point folks at the right documentation but I'm not going to be spoon feeding info on demand, certainly not when all of that info is so readily available via a few minutes of reading around a topic.

thanks then i'll work on trying to tie it together, thanks for the link at least. i might need to understand something i don't know yet.

My Midnite Classic 150 controller has an external relay that you can set to turn things on/off at voltage set points of your choosing. I currently turn my inverter on at 52v and off at 48v to encourage charge/discharge in the middle range of the battery - in hopes of extending its life.

You can use the Batrium + expansion relay to do the same thing - e.g. explicitly control the inverter on/off by voltage settings of your choice thru Charging (ON) option or other.
