What is PCBA For energy storage system ESS?:
An Energy Storage System (ESS) is a specific type of power system that integrates a power grid connection with a Victron Inverter/Charger, GX device and battery system. It stores solar energy into your battery during the day for use later on when the sun stops shining.
It allows for time-shifting power, charging from solar, providing grid support, and exporting power back to the grid.

FAQ
1 Q：For ODM service, if you can provide software design?
A：Yes, we can provide not only the software design, but also the firmware design.
2 Q：What's your L/T for PCBAs?
A: Sample is 4W,for mass order, the materials generally need 8W, and the production needs 4W. Materials that are longer than 8W we can stocked for customers. Most of the materials we can stocking for customers for free, but we need to confirm if the materials are special and only used by your company that other customers can not use them, which need your to pay the deposit.
