New project of Les Amis de Gambie


New project: ‘Power for Power!’

We generate our own electricity in the orphanage with solar panels and wind turbines. The generated electricity of 24 volts is stored in a large 2700 ampere battery.

As the orphanage requires 230 volts, as you do too at home, inverters (also called transformers) are connected to the battery. These inverters transform the voltage from 24 to 230 volts.

The orphanage has four circuit-breaker groups, for each building and a separate one for the water pump. Each group is powered by an inverter, so there are in total four inverters. The inverters each produce a maximum of 2500 watt. Therefore, the maximum amount of electricity that can be demanded per group is 2500 watt. In order to translate this into western energy terms: this is the electricity that is necessary to be able to use a hair dryer and a coffee maker at the same time or a vacuum cleaner and a television together with a few lamps.

Two of these groups - and thus two inverters - are running twenty-four hours a day at full capacity to provide 230 volts for lights, refrigerators, freezers, etc. The capacity of the two other inverters is used in full but not twenty-four hours a day.

Our existing inverters vary in age and are between six to ten years old: Ten years equates to 87,500 operating hours, in an ambient temperature of about 40°C with high humidity and a lot of dust! One of our inverters, which is not  even working under full load day and night to operate the water pump, broke down very recently, which was a cause for concern as no electricity means no water! Fortunately, we do have an emergency back-up system for the water supply.

It is clear that the installed inverters have reached the end of their useful life technically. Therefore, we can no longer wait until another inverter starts to malfunction: the orphanage urgently requires new inverters.

The existing total installed inverter capacity is 4 x 2.5 kilowatt = 10 kilowatt. We would like to replace these four inverters with three new inverters of each 4 kilowatt. As this new type of inverter can be connected in parallel, we would then have a capacity of in total 12 kilowatt for each group.

The total cost for replacing the inverters, small material and transport costs per sea container to Gambia amounts to €8,136. As organisation member Jean and vice-president Gert-Jan can install and connect the inverters themselves, we do not have to pay any assembly and installation costs.

We realise that it will certainly not be easy to obtain funding for this expensive project and we would therefore appreciate it very much if you could help us with this. You would really help us enormously by transferring your contribution to account number IBAN LU42 0030 6563 9934 0000 (BGLLLULL), in the name of the organisation Les Amis de Gambie citing ‘Power for Power!’ Thank you very much for your contribution!
