Control discharge of solar photovoltaic power systems need to pay attention to two

Zhongshan solar panels - Guangdong energy technology co. , LTD. , about solar panels, photovoltaic power generation in the process of discharge control two aspects need to be aware of.

- zhongshan solar panel factory Guangdong energy technology co. , LTD. In the process of solar panels, photovoltaic power generation discharge control has two aspects need to pay attention to. ( 1) Conventional process control

this control mode can only set the battery discharge control points. When the battery voltage drops to this point, the controller off load. This control method is relatively simple, but when continuous cloudy or system overload, the battery will inevitably over discharge, once the battery voltage reached discharge points, battery charging system will be forced to stop working. ( 2)

the battery discharge process control algorithm based on the residual capacity of battery SOC control the whole process of battery discharge, which in addition to the set point of SOC of the battery discharge = 0, also added a few control points, SOC =

80% and charged state = 50%. , every day before discharge in the system to detect the residual capacity of the battery, and then according to the residual capacity setting load power or work time of day. This control method can effectively avoid excessive battery discharge, avoid excessive battery discharge lead to a vicious shutdown system.
