Ha, I have the same problem.
Did you purchase the 200ah Ampere Time rated for 200amp load or 100amp load? My battery is set up for 120amp continuous load, so a 2000W inverter (2000 / 14 = 143amps) would trip the BMS' overcurrent protection. I set up another 2000W inverter and ran my heat gun to verify on my system. The BMS tripped within seconds. Not a big deal for me because I'm just going to use it for computer charging and other low power things.
