6
b. Recover when load is reduced: resume normal charging( 30A) when the heat sink
temperature is <70°C.
c. Stop charging when the heat sink temperature is ≥90°C; resume charging when the heat
sink temperature is <60°C.
5. External temperature compensaon funcon
(only for AGM/STD baery)
a.1.The system will automacally 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.
1. 12V baery charging temperature ≤0°C- -40°C 14.1 ±0.3 VDC
(test external analog resistance430K (-20°C))
2. 12V baery charging temperature: 0°C-20°C±5°C 13.8 ±0.3 VDC
(test external analog resistance 100K (10°C)
3. 12V baery charging temperature ≥20°C±5°C 13.5 ±0.3 VDC
(test external analog resistance 39K (30°C)
4. 24V baery floang charge temperature ≤0°C- -40°C 28.2 ± 0.3 VDC
(test external analog resistance 430K (-20°C)
5. 24V baery floang charge temperature 0°C-20°C±5°C 27.6 ±0.3 VDC
(test external analog resistance 100K (10°C)
6. 24V baery floang charge temperature ≥20°C±5°C 27 ±0.3 VDC
(test external analog resistance 39K (30°C)
6. WIFI networking funcon
a. The product may integrate WIFI module or not.
b. If the product integrates a WIFI module, you can install the mobile APP, control the load
switch through the APP and vie
w the MPPT charger data in real me, such as baery
voltage, charging current, etc.
7. The LCD backlight is turned off if there is no buon operaon in 1 minute; any buon
operaon will automacally acvate the LCD backlight.
8. a. USB baery input undervoltage/overvoltage protecon (10.5V/30.5V), baery input
undervoltage/overvoltage recovery (11V/30V);
c. USB output 2*5V/3A.
