Maximizing the efficiency of solar power generation MPPT converter
This is a power supply with MPPT control that can maximize the efficiency of solar power generation. It operates by tracking the optimal operating point of the PV, which fluctuates due to changes in solar radiation caused by weather conditions, and supplies maximum power to the DC bus line.
By adopting a buck-boost converter, it is possible to set the PV string voltage (50–1000VDC) ⇔ DC bus voltage (240–850VDC) not only for boosting but also for bucking operation, so the PV string voltage can be set regardless of the DC bus voltage.
The size is W422.8 x H88.0 x D530.0 (mm), a 19-inch rack mount type (height 2U). As it is a non-isolated type, it achieves high efficiency (97.5%) and minimizes power loss.
By adopting ModbusRTU (RS-485) communication, it is possible to read operating status, input/output voltage and current, as well as perform settings and operation instructions.
Feature
- High Voltage, Large Capacity Power Supply.Input: Up to 1000VDC, Output: Up to 850VDC, Power: Up to 12kW (Capacity can be expanded by parallel connection)
- MPPT (Maximum Power Point Tracking) Control
- High efficiency through non-isolation (Efficiency 97.5%)
- Operation status, input/output voltage and current reading, settings, and operation commands are possible via ModbusRTU (RS-485) communication
Benefits
- Reduction of system and operation costs
With 97.5% high efficiency and high voltage,
In addition to thinner wiring and reduced materials,
Heat generation is suppressed, reducing air conditioning load. - Reduction of installation and maintenance work hours through communication functions
Monitoring of voltage and current and various settings are possible via Modbus communication.
Contributes to reducing work hours for stable operation and troubleshooting. - Space-saving and flexible capacity expansion
The slim 2U design enables the construction of high-capacity power supplies in minimal space.
Parallel connection allows flexible response to future scale expansion.
