GENERAL INFORMATION:
!
IMPORTANT
• Due to the installation environment or load work , t he
system may not stabilize the battery voltage at a constant
voltage. The controller will accumulate the time when
the battery voltage is equal to the set value. When the
accumulative time is equal to 3 hours, the system will
automatically switch to float charging.
• If the controller time is not adjusted, the controller will
equalize charging following the inner time.
• Float Charging
After the constant charging stage, the controller will reduce the battery
voltage to the oat charging preset voltage by reducing the charging
current. During the oating charge stage, the battery is charged weakly to
ensure that the battery is maintained in a fully charged state. In the oat
charging stage, loads can obtain almost all power from the solar panel.
Suppose loads' power exceeds the solar array's power. In that case, the
controller will no longer maintain the battery voltage in the oat charging
stage. When the battery voltage goes lower than the set value of the boost
recharge voltage, the system will exit the oat charging stage and enter
the bulk charging stage again.
