Application Scenarios
Recommended applications and deployment scenarios
Backup Power
For grid and generator backup systems. PV serves loads first, the battery maintains supply during outages and the generator starts when its configured conditions are reached.
Mini-grid
For remote installations where PV, storage and a generator work together to supply critical and normal loads.
ESS / Self-consumption
For stable-grid sites using metered charging and discharging to maximise solar self-consumption and manage permitted export.
