Recover when load is reduced: resume normal charging( 30A) when the heat sink
temperature is <70°C.

Stop charging when the heat sink temperature is
≥

External temperature compensa
tion
function
(only for AGM/STD ba

ery)
a.1.The system will automatically adjust the float voltage according to the ambient temperature.
The external temperature probe is preferred. If the external temperature probe is not connected
(or the external temperature is <-40°C), use (temperature ≥ 20°C± 5°C) by default. 2. The voltage
may vary when the input energy is insufficient to stabilize the energy required for the float
charging.
