The LG RESU series will trip it's breaker at around 10% Soc. It will require a human unless the LVD on the inverter is set higher than the battery. Yes Sir it is our responsibility to educate our users or have plane tickets (: Will be installing the Discover battery soon into Xanbus. Dave Angelin

[RE-wrenches] heating any battery bank

2018-02-27 Thread Dana
At a couple of remote systems, I have housed the battery bank as follows. It is not cheap [$2,000 for pump, controller, & collector, plus the slab] but works very well: Flat plate Solar thermal collector installed at 60+°, pumped directly to a 6” insulated slab dedicated to the battery bank

Hi Drake, I agree. Li-ion batteries, like lead batteries, should always have a human overseer. This is a difficult reality to convey in our set-it-forget it, automated world. One function of a Li-ion battery EMS or BMS is to prevent over discharge. Once any battery cell reaches the lower limit

Snow on the array could be a very big problem with the heater load, inverter idle current and anything else that might be left on. Extended periods of heavy clouds can reduce power generation to be less than system's internal losses. It seems like a pretty big gamble to leave an expensive battery b
