hi I agree that SunDanzer battery, free solar direct drive (SDD) fridges have revoluntionized the solar vaccine fridge market. Two of their fridges are WHO preqaulaified thrugh extensive testing that approvees a product for sale through the UN. If you need a freezer too then SunDaner has also pioneered SDD freezers for immunization ice pack freezing.
If the health facility also needs some power for lights, fan and small battery recharging (e.g.cell phone, laptop, fetal doppler) then check out the B Medical Systes Health Center Kit that is approved by WHO to be coupled to a B Medical SDD vaccine frdge (or SDD fridge freeer combination). WHO calls that category of products "Energy Harvesting" and the control system always priorities the vaccine fridge power first and then harvests the excess for user selected loads, about 500 Wh/day are presently availalbe and more in the future is the hope. If the energy harvest control fails it does take down the fridge.
