Situation
1. Restart the charger.
2. If the problem remains, please contact your installer.
1. Keep the charger in the cool environment.
2. If the problem remains, please contact your
installer.
1. Check the battery wire connection.
2. If the wire connection is ok, please contact your
installer.
1. Reconnect the battery to the charger.
2. If the problem remains, please contact your
installer.
1. Please check the voltage of the solar panel, it should be less than 140V or 190V.
2. If the voltage is ok, please contact your installer.
1. Check your remote temperature sensor and
your battery ambient
temperature.
2. If the problem remains, please contact your
installer.
1. Check your remote temperature sensor and
your battery ambient
temperature.
2. If the problem remains, please contact your
installer.
1. Check battery wire connection.
2. Push the button, if the problem remains, please
contact your installer.
In Equalize stage, based on maximum charging current of battery equalization, the controller will supply
solar power to charge battery as much as possible until battery voltage raises to battery equalization voltage.
Then, constant-voltage regulation is applied to maintain battery voltage at the battery equalization voltage.
The battery will remain in the Equalize stage until setting battery equalized time is arrived.

However, in Equalize stage, when battery equalized time is expired and battery voltage
doesn’t rise to battery
equalization voltage point, the solar charge controller will
extend the battery equalized time until battery
voltage achieves battery equalization
voltage. If battery voltage is still lower than battery equalization voltage
when battery
equalized timeout setting is over, the solar charge control will stop equalization and
transfer to
float stage.
