Putting solar power into diesel based grids is easy but maximizing the share of solar is a real challenge. To save on diesel consumption, diesel has to be substituted by other energy sources. Solar energy is a cheap energy source but without intelligent system control it is hard to reach high solar shares in diesel grids. Uncontrolled solar energy feeding into a diesel grid can, even with a small share of solar, lower the diesel workload to a disadvantageous level in solar peak times causing inefficient operation of the diesel gensets, more frequent maintenance cycles and damage to the equipment. If too much solar generation capacity is installed, even reverse power into the generator is possible, which can cause a blackout in the best case scenario and equipment destruction in the worst case.
This article shows how the SMA Fuel Save Controller 2.0 (FSC-20) facilitates high solar shares in diesel based micro-grids and thereby saves diesel as well as money in a smart, flexible, safe and easy way with SMA supporting you whenever you need it.
