C07MOS tube overtemperature.Fault
Description

MOSFET / BMS power-stage over-temperature fault displayed on the LCD BMS fault code / flag screen (section 4.4).

Cause

1. The inner temperature is over the limitation. 2. Check whether the ambient temperature is too high. (Per section 1.3 item 13 the unit must not be installed below 0 degC or over 55 degC, or above 80% humidity; charging temperature range per section 2.3 is 0-55 degC.).

Recommended fix

1. The inner temperature is over the limitation. 2. Check whether the ambient temperature is too high. Stop charging / discharging, let the unit cool, and improve ventilation.
