Introduction:
In the realm of solar power systems, the functionality of on-grid solar systems is contingent upon the availability of grid power. When faced with a power outage or grid failure, these systems automatically shut down as a safety measure known as anti-islanding. While this is crucial for the safety of maintenance personnel, frequent shutdowns can impact the return on investment (ROI). This article explores the solution to this issue – the DG PV Synchronization device – and sheds light on its significance in maintaining uninterrupted solar power generation.
What is DG PV Synchronization?
On-grid inverters rely on a reference voltage from the grid, but a diesel generator can serve as an alternative reference in the absence of grid power. However, certain conditions must be met. Unlike grids, surplus solar energy cannot be fed into a generator, as it is not designed to receive power. To address this and ensure optimal functioning and fuel efficiency, a generator needs to operate at a minimum of 30% of its capacity.
This is where the DG PV Synchronizer comes into play. This intelligent device facilitates communication between the diesel generator and the solar inverter, enabling the continued operation of the PV system during blackouts. The synchronizer ensures that the generator runs at least 30% of its capacity before instructing the PV system to commence generation. Additionally, it prevents the back-feeding of excess solar power into the generator, earning it the moniker of a zero export device.
Example Scenario:
For instance, if the DG capacity is 100kW and the demand is also 100kW, the DG PV device ensures that 30kW of demand is met through the generator, while the remaining 70kW is supplied by the solar panels.
Benefits of DG PV Synchronization:
Utilization of on-grid solar systems during blackouts.
Significant fuel savings by meeting only a portion of the demand through the generator.
Enhanced reliability of power supply, with the device adjusting DG power to meet demand if solar generation decreases.
Choosing the Right Generator Capacity:
Contrary to the assumption that a low-capacity diesel generator is sufficient for reference purposes, it is advisable to invest in a generator that matches the load capacity. This ensures that the generator can compensate for fluctuations in solar generation caused by external factors such as cloud cover or rain.
Where to Obtain a DG PV Synchronizer:
