The mother board (main board) of the solar inverter supports SKD or CKD component combinations, which can be purchased according to system requirements and the casing can be assembled by the user.

 

■ Solar Inverter Mother Board (Main Board) Highlight


 

The motherboard, also known as the main board, is the core component of solar inverter, plays an important role. They support export in SKD or CKD modes. Our engineers carefully considered export convenience during the initial design phase, shipping the motherboard, casing, and accessories separately. Customers can assemble them themselves upon receipt, reducing overall shipping volume, warehousing and logistics costs, and circumventing tariffs or policy restrictions on complete unit imports in some regions. Inverter installation and functional testing can be completed without complex assembly. This helps customers establish localized production systems, enhance price competitiveness, and ensure supply chain flexibility and delivery efficiency.
