DC power from solar panels cannot be easily switched off during daylight. A lockable door is vital to ensure that only certified electricians can open the box, satisfying strict corporate liability and regional building safety regulations.
The integrated DC SPD protects against indirect lightning strikes, induced overvoltages, and grid surges. For direct strikes, a comprehensive lightning rod system should be installed on the building structure.
Yes. We offer flexible manufacturing options ranging from small-scale 2-string residential setups up to 24-string high-capacity industrial configurations.
