PV-Installation at DMI Sisters in Juba, South Sudan

After independence from Sudan in 2011, peace lasted only a short period of time. Since December 2013, a civil war has been raging in the country. Simplified viewed, it is a conflict between two ethnic tribes.
Since 2011, around 18 Sisters of the organization DMI have been living in the region of Wau and in the capital Juba. They help to raise awareness for peace and reconciliation between the two tribes.



The off-grid PV-solar system was designed to enable the DMI sisters uninterruptable power supply. It consists of 48 solar panels, 10 stacks of Greenrock AIB solar batteries (of 48 Vcd 2.7KWh), a backup generator, solar charger, inverters and all required accessories for installation & grounding.



The old food store was modified in order to accommodate the batteries. AIB solar batteries were chosen as they are long lasting, environmental friendly and resistant to high outside temperatures.



The Power room is including:

  • Quattro 48/1500/200-100/100-230V inverter/charger
  • Victron color control Gx device for monitoring
  • Victron Smartsolar charge controller MPPT 250/100-MC4
  • Dc combiner HISbox 2 MPPT each string T1/2
  • Ac distributor

All equipments were connected, programmed and tested in line with the regulation. The power outputs to the different buildings are through underground cables to the different buildings and all cables are marked for easy identification.



The centre was supplied with Grundfos submersible pump SQE 1-35 for constant water supply. The pump is controlled by CU 300 together with a Potentimeter for grundfos CU 300-SPP1 to control the flow in order control the water level. The initial PVC riser pipes were reused and the whole activity was successful.



The centre was supplied with a GENMAC Generator Urban RG8PS (8.0KVA-230Vac) as a back-up power supply for the solar system as well as for the centre on by-pass. The generator is set to automatic mode with the signal from the programmable relay of the victron color control GX. The generator was supplied with the most important spare parts.


St. Daniel Comboni TB Hospital Marial Lou

Help for infirmary in South Sudan

The St. Daniel Comboni TB, Leprosy and HIV infirmary Marial Lou is located in the north of South Sudan in the administrative district Tonj East. The catchment area has in approximately the size of Upper Austria. The focus of the infirmary is on patients with highly infectious Tuberculosis, Leprosy and HIV. The infirmary has a bed capacity of 42.


To the tasks were counted:
  • Preventive TB-screenings, laboratory diagnosis and initiation of TB drug therapy for confirmed cases
  • Sensibility of community for TB
  • HIV testing and consultation of reported TB-patients
  • Care for TB-treatment breaker
  • Home visits
  • Admission of TB-patients


The challenges a small infirmary has to struggle:

The buildings are in a very bad condition and in need of a renovation. The infirmary has no own water supply but has an unusable fountain. For power supply they have a little generator, but the generator sometimes does not work and does not guarantee a continuously power supply. Furthermore they do not have a Beamer for showing videos about tuberculosis and their effects. Therefore they have a lack of health education and sensibility.


The priority list
  • To restore the water supply with solar pumps
  • Photovoltaik System for laboratory and infirmary
  • Beamer for health trainings
  • Subsequently the renovation of the infirmary and the ambulance building



South Sudan
Area 644.000 km²
(7,5x bigger than Austria)
Population 12,5 Mio
Population density 19,45 inhabitants/km²


The St. Daniel Comboni infirmary exists since 1994 and is one of 14 hospitals of AAA (Arkangelo Ali Association) in South Sudan. AAA is involved in the strengthening and improvement of life quality for pupils in undersupplied and difficult to access regions (e.g. Marial Lou) through provision of a free of charge health service, including TB-care, TB/HIV and Leprosy treatment.


Number of people their living conditions get better through this project
  • 42 patients (bed capacity)
  • ca 1200 pupils (incl. ambulances, etc.)
  • ca 100.000 pupils in the catchment area of the hospital
