- | ====== Zero Feed - The Why ====== | ||
- | |||
- | In India many states experience frequent and crippling power cuts. Solar rooftop systems are springing up everywhere, from small residential houses to large factories in attempt to save costs and in so doing reduce carbon emissions. | ||
- | |||
- | ====== Zero Feed - The How ====== | ||
- | |||
- | |||
- | A power meter is installed at the incomer of the building, and is used as a reference to determine the active power load on the building. | ||
- | |||
- | ====== DG Protection - The Why ====== | ||
- | |||
- | |||
- | Diesel generators bridge the gap during power cuts and in some locations they are used 24/7. When coupled with solar grid tie inverters, a saving of fuel can be achieved. | ||
- | |||
- | ====== DG Protection - The How ====== | ||
- | |||
- | |||
- | A power meter is installed on the output of the genset, and connected to the Wattmon in the same way as with zero feed. The Wattmon monitors the energy generated and if it drops below a set point, it will reduce the power of the inverters so as to ensure that the generator does not trip. | ||
- | |||
- | Both these systems can be installed at the same site by using two power meters and some software customization which will allow the set points to vary based on whether grid energy is available or whether the system is running on the generator. | ||
