Ac200p Not charging from 200w drive tech panel

Been trying to charge from 200w panel but doesn’t register sometimes or a fault comes up about calibration, the panel is 18v output and the input point is 35 to 150v on BLUETTI, it is brand new but may need a firmware update but couldn’t find a serial number either ok thanks

You state that your panel output is 18V but your Bluetti requires a minimum of 35 volts. Since 18 is less that 35 you will need to increase the voltage by adding another panel in order for charging to occur.


Thanks Scott will try another panel on it
