The Loreto Primary Health Care Unit is the newest of the core programs at Loreto Rumbek.

The components of the care provided at the LPHCU include:

  • Health education
  • Promotion of mother child health
  • Nutrition
  • Identification and referral of children for immunization
  • Promotion of safe water and sanitation

 

PV System

The Pv system consist of three sections which include:

  • Pv power for internal lighting and sockets
  • Pv power for two cooling units
  • Pv power for pumping system

 

The Pv power for the internal circuits consists of 21 Axitec solar panels of 300Wp mounted on the roof using schletter mounting materials. The system is connected through string connection boxes which have surge protection devices. The Cooling unit consists of 4 Axitec solar panels of 300Wp and 2 Victron Gel Batteries. The Pv power for pumping system consist of 7 Axitec solar panels of 300Wp.

 

Power Room

One of the rooms in the health unit was taken up for the equipments to be installed. On the wall from left to right, Ac distribution panel, Victron Multiplus 48/5000/70 – 100 230 inverter/charger, lynx DC distributor (for inverter and solar chargers), two string connection boxes, Greenrock DC combiner box ( for the AIB batteries) and finally two Victron Blue solar MPPT 150/85 charge controllers

There are 5 stacks of Greenrock AIB Aqueous ion exchange batteries (salt water batteries) 48Vdc, 2.7Kwh each that are assemble at the corner behind the entrance door for this particular room. The advantages of this battery type are that they are environmental friendly (containing no hazardous materials) and they are resistant to high outside temperatures.

Cooling Unit

This consists of two independent sets of Steca solar fridge/freezer type PF240, 12/24Vdc powered from two Victron Gel 12V 220Ah Deep cycle batteries placed on a locally fabricated battery stand. Two batteries are connected in series for 24v system. The battery sets are charged independently through Victron Blue solar MPPT 150/35 charge controller and all Pv power are surge protected in the string connection boxes mounted next to individual charge controller. The two sets of batteries are monitored independently from Victron battery monitor BMV – 700 mounted on the box.
The cooling units were programmed for the intended usage. One is programmed for freezer mode for ice blocks and other items and one programmed for fridge mode for temperature 2°C to 8°C for vaccines and drugs.

 

Pumping System

The pump control system consists of the Grunfos IO 101 Control unit and Grundfos CU 200 and surge protection devices for the float switch signal line and the Pv power. The borehole in which the pump is lowered is about 25 to 30m from the building and a separate grounding for the pump was made. The pump was lowered down the borehole by local St Peter Claver students together with their instructors both electrical and plumbing. The required training was done to St Peter Claver training centre and the management staffs of Loreto School.

Installation

The installations were done using local students of  St. Peter Claver training school and a solar expert from Uganda. After installation the system was commissioned in the presence of a BBM technician.
