In today's era of rapid development of renewable energy, photovoltaic power generation as a clean and efficient energy solution has received widespread attention. In this system, the inverter is regarded as its "smart brain", which is responsible for converting the direct current generated by the photovoltaic module into alternating current that can be used by the home and the grid. With its excellent technology and intelligent functions, Deye inverter has become an indispensable part of photovoltaic power stations. It not only improves the power generation efficiency, but also ensures the safety and reliability of the system. Next, we will delve into the many intelligent functions of Deye inverters, revealing how it guarantees the efficient operation and economic benefits of photovoltaic power plants at all levels.

1. Automatic start and stop

Deye inverter equipped with intelligent automatic start and stop function. After sunrise, as the solar radiation gradually increases, the voltage of the photovoltaic cluster rises. When the voltage reaches the starting voltage required by the grid-connected inverter, the inverter automatically starts and starts generating electricity. On the contrary, the sun goes down in the evening, the voltage is reduced below the starting voltage, and the inverter will automatically stop, saving unnecessary energy consumption.

2. Intelligent anti-PID effect

Photovoltaic modules may have PID (potential-induced attenuation) effect under the influence of voltage for a long time, thus reducing power generation efficiency. By automatically raising the negative voltage of the component when the DC bus voltage is lower than 50V, the grounding voltage is kept close to 450V, reducing the charge accumulation, effectively inhibiting the PID effect, and ensuring the long-term stability and power generation capacity of the photovoltaic module.

3. Smart MPPT

MPPT (Maximum power point Tracking) technology is one of the core advantages of Deye inverters. Under different lighting and temperature conditions, the output power of photovoltaic modules will be different. By monitoring the voltage and current in real time, the inverter automatically adjusts the working state to ensure that the system is always running at the best power point, thereby improving the power generation efficiency.

4. Smart island prevention

In order to prevent islanding effect, Deye inverter built-in advanced anti-islanding protection circuit. When the power grid has high and low voltage or frequency fluctuations, the inverter will disconnect from the power grid in time to ensure system safety. Once the grid is back to normal, the inverter will be automatically reconnected to the grid to ensure continuous power generation.

5. Intelligent string monitoring

The Deye inverter realizes the intelligent series-by-series monitoring of each PV cluster. Through the high-precision DC sensor, the current signal of each group string is detected in real time. Once the fault is found, the inverter will quickly control the DC switch and send out trip protection and active alarm. This active safety mechanism significantly improves the overall reliability of the system.

6. Intelligent air cooling

Heat dissipation is a key factor in inverter performance. With intelligent air cooling technology, Deye inverters are equipped with high-performance fans and built-in temperature sensors to monitor temperature in real time. When the temperature reaches the set threshold, the fan will automatically start to ensure the stable operation of the inverter in the high temperature environment and extend its service life.

7. Intelligent reactive power compensation

In the scenario of photovoltaic self-use, the management of reactive power is equally important. Deye inverter can dynamically adjust reactive power output according to power factor and grid voltage to meet the relevant requirements of the grid, thereby reducing the additional costs caused by low power factor and optimizing economic benefits.

8. Intelligent recovery connected to the network

Deye inverter equipped with intelligent recovery grid-connected function. When the state of the power grid is unstable, the inverter will enter the standby or fault shutdown state. Once the operating conditions return to normal, the inverter will automatically recover and connect to the grid after self-test, without manual intervention, greatly improving the self-regulation ability of the system.

Through these rich intelligent functions, Deye inverter not only improves the power generation efficiency of photovoltaic power stations, but also ensures the safe and stable operation of the system, thus creating greater economic benefits for users.
