Battery power with generator charging
Hello, I am a volunteer for a non profit org. Doing great work in Tanzania,Africa. There is no power grid. They have a guest residence 8 rooms and a kitchen. There is a 21 kV diesel generator (230v 50 hz) that is the only source of power. My thoughts are to add a battery bank to provide CONSTANT power, needed for water filtration and refrigerated medical supplies. What is the best approach to get this resolved in Tanzania? The plan is to expand and add a medical clinic. They are on a limited budget and are resisting solar panels because of cost. Can we start with a smaller battery bank and add on as needed? Do you know of any contacts in Dar es Salaam?
