E. Equalization Time
–The charging at the selected equalization voltage will continue for this
number of hours. This may take more than one day to complete.
F. Equalization Interval
–Equalizations are typically done once a month. Most of the
cycles are 28 days so the equalization will begin on the same day of the month. It can
be set by Dip Switch 4~6 for different interval days.
Each new cycle will be reset as the equalization starts so that a setting day period will
be maintained.
These 8 standard battery charging algorithms will perform well for the majority of battery
systems.
5 Diversion Charge Control
As the battery becomes fully charged, the W4B-120C will divert excess current from
the battery to a dedicated diversion load.
This diversion load must be large enough to absorb all the excess energy, but not too
large to cause a controller overload condition.
5 .1 Diversion Charge Control
The W4B-120C will use PWM charging regulation to divert excess current to an external
load. As the battery becomes fully charged, the FET switches are closed for longer periods
of time to direct more current to the diversion load.
As the battery charges, the diversion duty cycle will increase. When fully charged, all the
source energy will flow into the diversion load if there are no other loads. The generating
source is typically a wind or hydro generator.
The most important factor for successful diversion charge control is the correct sizing of
the diversion load.
If you are not confident and certain about the installation, a professional installation by your
dealer is recommended.
5 .2 Diversion Current Ratings
The maximum diversion load current capability for the W4B-120C WS-120C is 120 amps.
The diversion loads must be sized so that the peak load current cannot exceed the maxi-
mum rating.
