HOSPITAL
Charity-run hospital in Cap-Hatian, Haiti
After the devastating earthquake in Haiti, people are still rebuilding and recovering. At a charity-run hospital in Cap-Haitian,
Haiti, a comprehensive hybrid power system is installed to power a complete hospital. At the heart of this system there are
ve Victron 24/5000/120 Quattro’s connected in parallel. Only a small grid connection is available, with a capacity of hundred
Ampères. When the required power is higher, the Quattro’s will supplement the grid with energy from the batteries. This is a
unique Victron feature called PowerAssist, that synchronizes the output of the inverters with the grid. Eectively adding power
to the grid. When the load reduces, the spare power is used to recharge the battery bank.
On top of being too small, the grid connection is also unreliable. On a loss of grid power, the Quattro’s seamlessly pick up the
power demand, so the Hospital can count on a reliable power supply. They’ll also automatically start the 40kVA generator
when the power outage is not restored quick enough.
All six buildings of the hospital have their roof lled with solar panels, eighty pieces of 180W panels in total. These panels are
connected to the outputs of the Quattro’s via grid inverters, powering the loads. All excess solar power is used to charge the
batteries.
