Took my AC200L camping with me over the weekend and drained it to 0% cooking and other things. Went to charge it by connecting to the 20A outlet on the cybertruck. The AC200L was set at the max 12A setting and started out charging at 300W. A few minutes later it started going up to 1300W, restarting and then ramping back up to 1300W and then rebooting again. After a few cycles like that, the cybertruck cut the feed to the outlet (was it drawing too much?). This behavior was consistent with and without “Grid Adaptation” on or off. What’s odd is that even limiting charge current to 9A, it still ramped to 1300W.
Cybertruck’s 120V outlets are 20A in total between the two outlets. Can you check with Tesla if the output is pure sine wave? AC200L requires pure sine wave AC power to charge.
Update: I discharged my ac200L down to 26% and plugged it into the CT and it started charging fine. I have it on standard charging mode with max 9A grid charging.
I wonder if it behaves different at very low SoC. The above issue happened in the single digit SoC (like 3%). It would start charging at low rates, like 300W and then suddenly go up higher which would trigger the CT breaker.
I had mine at up to take a max charge of 20 amps . It cycles up to 1450w and then cycles off… my firmware is up to date. I’ll try your settings and see if it changes anything
