In a multi-phase system, the charge current is configured per phase. There is not a total charge current which the system adheres too. This means that, for example when there is a relatively small battery bank, and a huge over production of PV on L1, and not on the other phases, only part of that over production on L1 will be used to charge the battery. | In a multi-phase system, the charge current is configured per phase.

- | The battery life feature prevents low battery state of charge over a long period. This may happen when there is insufficient PV power available to recharge the battery every day, for example in winter. | ||

+ | |||
+ | In case the expected Solar energy reduces, because of less sun shine, the system | ||
+ | |||
+ | In case the expected Solar energy increased, because of more sun shine, the system will automatically decrease its low SOC limit. So that, with this increased expected Solar Energy, the battery will still be fully charged at the end of the day to approx 100%. | ||
+ | |||
+ | Ask yourself, "Why should the battery be fully discharged, and stay that way? With as a result no reserve power in case of mains failure, and possible also a damaged battery" | ||

+ | * In case of mains failure, it is best to have spare energy available to power the loads from the battery. Continuously operating in a low state of charge serves no purpose. | ||
To do this we introduce a dynamic lower limit on the state of charge. Discharging is allowed only if the state of charge exceeds the limit. The limit is adjusted every day. On days with little or no surplus PV power the limit will be raised. And on ' | To do this we introduce a dynamic lower limit on the state of charge.
