UNICHIR Hospital, based in Beni, one of the DRC's territories, has taken an important step towards using energy of the moment by implementing an efficient back-up system for its infrastructure. The installation guarantees a constant, uninterrupted supply of power to key equipment such as operating theatres and other vital hospital facilities, based on a combination of converter-chargers, lithium batteries and efficient energy management.
In addition, the hospital covers an area of approximately one hectare and was built in several sections, each fulfilling specific functions. These segments include: the OP (operating) block, the Patient block (hospital rooms), the laundry and sanitary segment, the technical segment, the water tower, the incinerator area, as well as segments planned for the future, such as the maternity ward.
Each unit has its own specific electrical installation features:
Lithium batteries provide energy storage for use in the event of a power cut on the local grid. Hence the installation of 30 BYD LV Flex lithium batteries, each with a capacity of 5 kWh.
At Hôpital Unichir Beni, the backup strategy consists of six Victron Quattro converters, each rated at 15 kVA. These devices operate on a 48-volt direct current (DC) system and generate a 230-volt alternating current (AC) output. Each inverter can deliver an apparent power of 15 kVA, giving the system a total capacity of up to 90 kVA from the six units deployed. This mechanism guarantees an adequate supply of power to meet the hospital's energy needs, even in the event of power cuts.
A low-voltage switchboard (TGBT) has been installed to centralize and control the various energy sources.
It is combined with a general distribution board to ensure balanced power distribution throughout the hospital. This ensures appropriate distribution of energy across different circuits.
The architecture of the installation was designed to guarantee continuity of service, ensuring protection against load shedding and optimized use of electrical energy.
Two phases of electrical installation at the hospital have been completed: the first involved the completion of the electrical installation for the operating theatres and patients, as well as a 45kVA/100kWh back-up system; the second involved the installation of the mother-child block (maternity ward and common rooms), as well as the extension of the back-up system's capacity from 45 VA/100 kWh to 90kVA / 150 kWh. A new training phase is also underway.
