Mine was hand written on a piece of paper taped to the bottom of the watchmon

Thanks
Would have helped if I hadn't put it into green holder first.   Rolleyes

I have spoken to batrium and they have added a section to faq on its location now.
4 kw grid tied system

20 kWh 12v lead acid (don't ask) off grid system used as a giant ups for my servers and network and to provide house power incase of power failure

10 kWh 48v lifep04 with 1.5 kw of solar on a mpp5048 mppt and a flatpack2 2000/48 mains charger. Grid tied with limiter to help even out the power usage at night

YOu can also turn that function off in the settings.. I'll find where it is tomorrow and let you know how

So what would be the difference between a charge controller and BMS? Is the former necessary with a setup such as Batrium?

I would say yes.  The charge controller takes the usually too high voltage from the solar array and converts it into an appropriate charge voltage.  The batrium should be expecting a nominal charge voltage and handles battery safety as well as the cell balancing.

Thanks Will. I read up a bit more following my question, but your answer definitely helps.

daromer, I think your analogy is off. The solar array would be the cow, the inverter/charger the milk matchine, and the BMS whatever they do to make it from whole to 2% (or skim, as it were).

hook: nope, the batteries are the cow, the BMS is the milk machine, the inverter/charger is the milk %age conversion portion. The thing here is that the milk machine can put milk "back" into the cow, and make sure the same amount flows evenly into each teet Tongue

not sure about the milk thing... Smile  different kind of energy.
Hmmm maybe the same,  sun lets gras grow --> cow eats gras --> cow make milk --> men consume milk.....
it is all solar energy Big Grin
