• The rotary switch position
• Pre-defined factory battery presets
• User defined battery presets
• Create, modify or delete a user defined preset.
This setting uses factory pre-defined presets for a large variety of battery types. These pre-defined charge algorithms are suitable
for almost all installations.
It is possible to also create user-defined battery presets. The chapter
Customize battery charge algorithm [19]
explains how to
do this. These user defined presets are stored in the VictronConnect App library. This is helpful in case multiple solar chargers
need to be configured, eliminating the need to define the entire charge algorithm each time a new solar charger is configured.
Expert mode
This setting enables or disables expert mode. It is by default set to "disabled".
The default charge algorithms work well for almost all installations. Only enable expert settings if your
equipment has special requirements.
When this setting is enabled the following parameters can be configured:
• Charger voltages: bulk, absorption and float
• Bulk: re-bulk voltage offset
• Absorbtion: duration, time and tail current
• Equalization: current, interval, stop mode and duration
For the meaning of these parameters see chapter
Battery charge algorithm settings [20]
Equalization
Equalization can cause damage to the battery if the battery is not suitable for an equalization charge. Always
check with the battery manufacturer prior to enabling equalization.
This setting can be used to disable or enable automatic equalization. When enabled, the amount of days can be selected when
equalization should repeat.
A manual equalization can be initiated by pressing the "START NOW" button. Use the manual equalize option only during
absorption and float charge stages, and when there is sufficient sunlight. The current and voltage limits are identical to the
automatic equalize function. The manual equalization stage lasts 1 hour, and can be stopped at any time by the Stop Equalize'.
The equalization setting might not be active, this can be the case if the battery preset does not support and
equalization charge, like is the case with lithium batteries.
Customize battery charge algorithm
This chapter explains how to modify a battery charge algorithm or to create, modify and delete user defined battery presets. See
the
Battery charge algorithm settings [20]
chapter for the meaning of all charge algorithm parameters.
