The Victron, Fronius and BYD power room in Monguno.
What it powers at the humanitarian hub in Monguno
The hub has offices and guest rooms for humanitarian staff. It runs about 34 air conditioners, plus water heaters, kitchen equipment, fridges and freezers, lighting and internet.
How we split the loads
We wired the hub into two circuits, so the things that matter most never go off.
Critical loads: always on
Lights, fans, computers, internet, fridges and security run on the battery 24 hours a day.
Heavy loads: smart control
Air conditioners, water heaters and kitchen equipment switch off when the battery drops to 40% and come back on at 60%.
What we did
✓ Kept the 66 kWp array already on the roof
✓ Added 12 new JinkoSolar bifacial panels
✓ Built the power room around 6 Victron Quattro inverters, a Fronius Eco inverter, 9 Victron MPPTs and 30 BYD batteries
✓ Joined the old and new parts into one system built for harsh conditions. This was the first hub we handed over.

How the load control works
We sorted every circuit in the hub with the client's technical team. Critical loads sit on the battery circuit and never go off. Heavy loads sit on a separate, controlled circuit. The system runs everything from full battery down to 40%. At 40%, it switches the heavy loads off and waits for the next morning sun. At 60%, it turns them back on. The generators stay as a manual backup, so the hub team can see and manage how much energy the hub uses.
