due to installation environment or operation with load, the solar charge controller
performs time accumulation until battery voltage reaches the preset value. After the
cumulative time reaches three hours, the system automatically transfers to floating
charging.
If the clock of the solar charge controller is not calibrated, the controller
performs regular equalizing charging in accordance with its internal clock..
Floating Charging
After a charging stage continues, the solar charge controller reduces battery
voltage by decreasing the charging current, and maintains battery voltage at the
preset voltage value for floating charging. At floating charging stage, the battery
undergoes very weak charging to ensure that the battery is in full charge state. At
floating charging stage, the load can obtain nearly all the solar power. If the load
exceeds the power provided by solar energy, the solar charge controller fails to
maintain battery voltage at floating stage. When battery voltage is as low as the
preset value for improved recovery charging, the system exits from floating charging
stage and re-enters fast charging stage.

2.1 Installation Precautions
◆
Exert great caution during battery installation. Before installing open lead-acid
battery, wear protective goggles. When you are in contract with battery acid liquid,
wash the involved part with water immediately.
◆
Do not place metal objects near battery to prevent short circuit.
