PV-Installation for the new Dormitory at Loreto School Rumbek

Loreto Rumbek is made up of a primary school, a secondary school and Primary Health Care. The school first opened in 2008 and provides much needed place of education for girls aged 14-20.

To give a lot of students the chance of accommodation, a new dormitory was originated. The project start was in March 2019 and lasted till December 2019.


PV System

This consists of 15 REC solar panels 295Wp mounted on this particular building using Schletter mounting accessories and surge protection devices.


Power room

The equipment is mounted on the wall arranged for the best possible connections and professional smartness to be achieved.

These include:

  • Victron Easysolar inverter (rewired in order to accommodate surge protection devices for both the input and output Ac circuits)
  • Victron Smartsolar charger MPPT 250V/100A – Tr
  • Two Enwitec boxes with Dc circuit breakers for the battery
  • Inverter
  • Solar charger
  • BYD Lithium Battery


A lithium BYD battery stands on the floor, fixed on the wall on its upper part to be firm to avoid any movement. It stands as close as possible next to the inverter in order to use the special interface cable between the inverter and the BYD battery system for good performance.
All equipment is wired in accordance to the standards and regulations, including grounding.



The big advantage of the Lithium BYD battery system is that it is maintenance free, unlike the lead-acid batteries it does not require occasional addition of distilled water.  Only general maintenance of the power room is required: Basic Cleaning and regular checks to avoid entrance of dangerous animals especially mice, lizards and other insects that can cause tremendous damages to the system.

Solar award for Radio Pacis

BBM-project partner RADIO PACIS in Arua, Uganda wins solar award. Moreover, the president of Uganda, Yoweri Museveni, visits the radio station.

BBM and RADIO PACIS have a long history together. The BBM built the radio station in the north-west of Uganda with the help of Know-How and also constantly expands it.

The radio station, planned by the BBM, was part of two gratifying events:

Firstly, RADIO PACIS won the well-known EUROSOLAR award in the category “One World Cooperation” for the innovative solar-power-system, which reduced the operational energy costs drastically and has a role model effect for the region.

Further on, the Ugandan president Museveni visited the technical part of RADIO PACIS and visibly impressed.
