Slow flashing (1× in 5 seconds):
Main battery voltage is normal
Fast flashing (1× per second):
Main battery over-voltage
ON: Main battery Low-voltage
Battery

OFF: no charging
Short flashing (1× per 2 seconds): Lithium Battery not
charging because temperature is below 0°C
Fast flashing (1× per second): Controller overheating
Slow flashing (4 seconds on, 1 second off): Reduced
charging current because temperature >50°C or <-20°C
ON: charging (B2B or solar charging)
Start II
Green

Compact:
Yellow)
OFF: No D+ signal, no charging
Flashing (1time/5 second): Start battery voltage < 11V
(During B2B charging, when the voltage of the starting
battery is < 10.8V, the charging will stop. Once the
voltage is, 12.5V charging resumes.
Fast flashing (1× per second): Start battery voltage > 16V
ON: Start battery voltage normal (11V to 16V)
For 24V batteries, multiply the parameter values by 2!
Solar
(only SSB
models)
Green
OFF: B2B charging
Slow flashing: PV voltage too Low (lower than the main
battery)
Fast flashing (1× per 2 seconds): PV overvoltage (> 50V)
ON: PV voltage normal
