SPECIFICATION OF PV CHARGE CONTROLLER

condition and recharging needs. The battery can be fully
charged safety and rapidly with pulse current. Pulse current
charging model makes battery having more time to react which
reduces the gassing volume and makes battery improving the
acceptance rate of charging current.
5.2
Bulk charging stage
In this stage, 100% of available solar power is used to charge
battery(s). Every time after the controller is rebooted, if it
detects the system voltage low than equalize charging point, it
will enter to bulk charging stage automatically.
5.3
Equalize charging stage
The controller will enter to equalize charging stage and keep a
constant-current charging battery(s) since the system voltage
reach to equalize charging point. Constant-current regulation is
used to prevent heating and excessive battery gassing. As to
factory default setting, the equalize charging stage will remain
120 minutes and then enter to Float charging stage.
5.4
Float charging stage
It will enter to float charging stage after the Equalize charging
stage is done. In this stage, it will use a smaller voltage and
current charging battery slightly. The purpose of Float charging
stage is to offset the power consumption cause by itself and
other equipment in the system, while maintaining full battery
storage capacity. Load(s) can continue draw power from battery
in float charging stage, even that the system load(s) exceed
charging current, the controller will no longer be able to
maintain the battery at the Float charging stage, it will return to
Bulk charging stage once battery bank system voltage below
than equalize charging point. The battery charging information
as follow:
