BLUETTI AC200P Died after 6 months

My Bluettie AC200P quick working after 6 months. At the time I had no way of trying to fix it or replace it as I had to travel to where I grew up as my Mom passed away then 4 weeks later my sister. I am finally getting back into life after 2 years and thought I’d plug my Bluettie into an outlet to charge. After over 24 hours, it never came on.

Any thoughts since I now have a $1700.00 brick?

@artistkc During the period when AC200P is not in use, have you charged AC200P regularly? It may be over-discharged. It is recommended that you charge it with a solar panel for a while to see if it can be activated.
