Recommended Posts

Hi i have 12x us2000b batteries in use with 2x Axpert 5kw inverters. Can anyone here please help me to get idea if my batteries working optimally. 

Will the usage during night with the load in graph drain the batteries to 20-30%. Cant seem to find place in Emoncms that give total battery KWh used say from 16:00 to -7:00 ?

Batteries charge to 100% at around 14:00

Thanks

I am not sure I understand your question, what is seen as optimal?

I dont think so, It seems like you have a average load of 1 kwh between 16H30 and 21H30 that will result in a usage of 5kwh, from there it seems like your average usage are in the region of 500 watts, if that line continues to 7H00  it will add another 4.75kwh to the sum. A total of  9.75kwh (38.8% of the banks capacity). Your total available power is 28.8kwh and you usage will leave you at approximately 66.2%
