Our solar inverter products are NOT for end users.
These are basically fully assembled and tested boards that should be interconnected with accessories such as display, keypad etc.. the required additional components such as cabinet, switches, fuses, terminal blocks, power chords etc. should be added and supplied along with required battery and solar panel to the end customer.
So our customers are typically system integrator(s) or value added resellers who will buy tested modules from us and build systems for the end customers.
