I waited over 6 months after placing an order on December 2, 2022. The SBV arrived on June 19, 2023. From the very beginning this has been a terrible experience. I purchased the SBV and a satellite battery expecting great things.
The system never would allow me to charge by AC and discharge by AC simultaneously (at the same time). Now the AC input is disabled in and out. I am getting all kinds of error codes. 309, 312, 002, 003, 004, 021, 022 and 223. The Led lights are not working. Firmware AC will not update (frozen at 57%)
Hopefully you they fix the problems or replace the SBV immediately.
