System criteria
Power Providers engaged in a process of installation of a solar power system designed using SMA PV and battery inverters to provide three phase power. This power was distributed to a segregated load base identified as ‘critical loads’ such as those for the operating theater, neonatal unit, laboratory, IT system and maternity ward. The process is ongoing and further phase engagement could see the solar power supply extended in the future to meet other less critical loads such as water pumping, administration, air conditioning etc.
