光伏离网系统的设计类型

SPF 5000ES离网机支持2~6台并机，系统可以做到10kW~30kW输出。离网机增加后，组件也需相应增加，尤其是备电需求大的系统，只配置合适容量的蓄电池组还不行，只有组件足够，才能发出电，存储电。

There are two situations where multiple parallel machines are required:

(1) Although the load is not large, one off-grid machine is available, but the backup power demand is large.

(2) The power of the load exceeds the rated output power of one off-grid machine.

The SPF 5000ES off-grid machine supports 2 to 6 parallel machines, and the system can output 10kW to 30kW. When the number of off-grid units is increased, the number of components also needs to be increased, especially for a system that requires large backup power. Therefore, a battery set with an appropriate capacity is not sufficient. Only sufficient battery sets can generate and store power.
