hi there,
My AC180 has decided to charge at only 285W when on mains power… saw on other forums that this was a common issue… few thought running battery to zero charge would “reset” the device - i did this, and when i started charging again, it did in fact then charge at full 1,100 watts… today battery was flat, started to charge and again it is capped at 285W… regardless of charge mode i select. at around 50% charge, it is now charging at 566W (Std charge mode as well as Turbo)
thoughts? solution? firmware update required? - I’m currently on the latest firmare
BMS firmware v1033.12
@slingard In addition to the setting of the charging mode, due to the characteristics of the battery, the charging power is related to the battery voltage, SOC, and battery internal temperature. If these three factors are too high or too low, the machine will actively limit the charging power in order to protect the battery life.

I’m guessing that you recharged right after a high watt discharge creating an elevated battery temp which is limiting the charge rate/
