The Gcwatjinga photovoltaic system comprises of the following components:
- 6.24 kW PV array
- 2x Victron BueSolar 150V/70A MPPT regulator
- 600Ah Battery capacity
- Inverter/Charger, Victron Multi, 48V/8000VA
- System Monitoring (BMV700, Color Controll GX)
The clinc was connected to the grid, which at time of system design and installation the grid connection plans were unknown to the engineer. As the clinic has PV installed, the existing system has been configured such as to allow for grid connection once the batteries reach a predefined SOC. This guarantees a continuous supply of power to the clinic and nurse houses.
In addition to the grid, a backup generator is incorporated in case PV as well as grid failure occur.
