Function PV inverter
3000w solar inverter only has the direct exchange conversion function, but also has to maximize the performance of the solar cell functions and system fault protection. Summed up automatic operation and shutdown functions, maximum power tracking control, anti-alone operation function (and network systems), automatic voltage regulation function (and network systems), the DC detection (grid systems), the DC ground fault detection function (grid systems). Here a brief stop function and automatic operation and maximum power tracking control. 1, automatic operation and shutdown morning after sunrise, gradually increase the intensity of solar radiation, solar cell output also increased, when the work required to achieve the output power of the inverter, the inverter starts running automatically. After entering operation, the inverter will always monitor the output of solar cell modules, as long as the desired output power of the solar cell module output power is greater than the inverter operation, the inverter will continue to run until sunset down, even rainy days The inverter can be run. When the solar cell module output decreases, the inverter output is close to 0, the inverter will form a standby state. 2, the maximum power output of the solar cell module tracking control function is varies with the intensity of solar radiation and the solar cell module itself temperature (chip temperature). In addition, as the solar cell module having a voltage increases with the current decline of characteristics, so there can get the best operating point of maximum power. Solar radiation intensity is changing, obviously the optimum operating point is changing. In contrast to these changes, and always let the operating point of the solar cell module at the maximum power point, the system always get the maximum power output from the solar cell module, this control is the maximum power tracking control. The most important feature of the solar inverter systems is included in the maximum power point tracking (MPPT) this function.
