How to make Deye inverter continue to maximize its effectiveness
In the use of solar photovoltaic systems, the inverter as the core equipment, directly affects the stability of the system and power generation efficiency. In order to help users better understand and use Deye inverter, we have sorted out the following common questions and their answers, hoping to help users better manage and maintain the photovoltaic system, to ensure the long-term stable operation of the system and power generation efficiency.
Q: Can the inverter achieve active and reactive power control?
A: Yes, Deye inverter supports a variety of active and reactive power adjustment modes, support LCD local Settings or APP, web remote Settings.
Q: What about the shortage of electricity generation?
A: 1. Observe whether there is a shelter around the photovoltaic panel (such as trees, buildings, etc.)
2.Check whether the photovoltaic panel has foreign bodies or accumulated dust that has not been cleaned for a long time
3.If the fault persists, contact after-sales personnel.
Q: Inverter external cooling fan does not turn, is this a normal phenomenon?
A: This is normal, Deye inverter adopts intelligent air cooling design, the internal temperature of the inverter is not high, the cooling fan does not work, only the internal temperature of the inverter reaches the threshold, the cooling fan will rotate to promote heat dissipation.
Q: Does DEYE support DC-side overmatching?
A: There are differences in light resources in different regions. For areas with limited solar irradiance, DC side overallocation can ensure the power generation needs of users. Deye inverter can support up to 1.3~1.5 times the DC side of the overmatch, and has a stable overload output capacity.
Q: Will the inverter installed indoors have radiation, will it affect people's health?
A: No! Deye Inverter is strictly tested by COC(National Quality Certification Center). There is no radiation hazard, it will not affect health.
Q: Can the inverter achieve active and reactive power control?
A: This is normal, because the whole inverter is cooled by the heat sink on the back, and only the normal heat dissipation inverter can operate normally. The ambient temperature for the normal operation of the inverter is generally within 60 degrees. If the ambient temperature is too high, the inverter will run without load. It is recommended to install the inverter in a cool and ventilated place to avoid exposure to sunlight.
Q: Will the addition of reactive compensation devices to increase the power factor lead to a reduction in the output of the inverter?
A: Adding reactive power compensation device to improve the power factor will not affect the power generation of the inverter, using the inverter itself to do limited reactive power compensation, power factor above 0.9, will not affect the power generation of the inverter; However, if the inverter power factor is set below 0.9, it will affect the active power output of the inverter and then affect the power generation.
