MdF Posted April 1, 2022 Posted April 1, 2022 (edited) Morning All, Have done some Googling, but would appreciate the expert feedback on describing exactly what the following three items mean for the laymen to understand in terms of how their solar-inverter-battery backup system works: (1) Battery shutdown capacity (e.g. 20%). (2) Battery low capacity (e.g. 30%). (3) Battery restart capacity (e.g. 50%). Just how do the above three items actually work when using your batteries to supply load to the house?

mzezman Posted April 1, 2022 Posted April 1, 2022 My understanding is: (1) Battery shutdown capacity (e.g. 20%) - when using the battery if the system gets to 20% then the batteries are shut down - no more discharge (2) Battery low capacity (e.g. 30%) - alarm will sound at this % but continue to discharge (3) Battery restart capacity (e.g. 50%) - the system will resume using the battery (after shutdown) at this % MdF 1 Quote

Theoretically the cycle would be repeated? (2) Battery low capacity (e.g. 30%) - alarm will sound at this % but continue to discharge So only an alarm feature this? (3) Battery restart capacity (e.g. 50%) - the system will resume using the battery (after shutdown) at this % Quote

Normal running should be managed by the Work Mode settings (charging and discharging when grid or solar are available I stand to be corrected though Quote
