OFFGRID LIGHTHOUSE
Several O-grid lighthouses on the South African coastline used to be powered with three old 12kW generators. The old genera-
tors were replaced by a new Solar system, which is a clean and silent alternative to generator power. The generated energy is
used to power all the loads at the lighthouses: radio communication, lights and special radar equipment to detect radar signals
from ships nearby.
The new Solar system consists of:
• 2 x 48/3000/35 MultiPlus in parallel
• 1500Ah C10 OPzS 2V batteries
• 16 x 230 Wp Solar Panels
• BlueSolar Charge Controller MPPT 150/70
• 10kW generator for back-up
• Precision Battery Monitor BMV-602S to monitor the main battery bank and generator battery. The BMV-602S automatically
starts and stops the generator based on state of charge of the battery bank.
• A Victron Global Remote with an I/O Extender for Remote Monitoring and also a Remote Generator start function.
