Excess solar power will also be used for battery charging. Sustain mode is exited when solar-charging has been able to raise the battery voltage 0.1 V above the sustain-voltage-level. Normal operation will then continue - with the battery providing power when insufficient energy is harvested from the PV array.
The charger will ensure that voltage level is maintained - using power from the grid when necessary. The maximum charge current it uses for this is 5 Ampére per unit. (5 A applies to all installations - regardless of system voltages (12 / 24 / 48 V). Excess solar power will also be used for battery charging.
When there is less PV power available than is required to power the loads (at night for example), energy stored in the battery will be used to power the loads. This will continue until the battery is depleted (ie. has reached it user-defined minimum % SoC).
BatteryLife tries to ensure that the battery will always be recharged to 100% SoC - every day. This is how it works: During periods of poor weather when solar energy is reduced, BatteryLife will dynamically raise the Low SoC limit which has been set. This has the effect of making less power available for consumption.
Our solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
