Victron VE.Bus Configuration Guide

10.1.6. Battery capacity
In order for the battery monitor to be able to correctly calculate the "state of charge" the battery capacity of the connected
batteries must be known. Use this setting to specify the connected battery capacity in Ah.
10.1.7. State of charge when bulk finished
Use this setting to specify what the "state of charge" is set to when the Bulk phase is finished. This helps to calibrate "state of
charge" value due to inevitable measurement errors that accumulate over several charge/discharge cycles.
10.1.8. Charge efficiency
Setting the charge efficiency takes into account losses that occur when charging to improve the accuracy of the State of charge
reading. If you find the state of charge accuracy is drifting over time, try adjusting this setting.
10.2. Grid
10.2.1. Accept wide frequency range
Set the sensitivity of frequency measurement. This setting is used to indicate whether it is necessary for the input frequency to be
exactly 50 or 60 Hz. This is a setting that is primarily used in conjunction with generators (speed may not always be stable) to
prevent the Multi from rejecting the input supply.
10.2.2. UPS Function
Determines whether the Multi should be critical of the distortion in the supply waveform.
If UPS Function is deselected, this automatically activates the function preventing the lower voltage limit from being exceeded
with heavy start-up loads! (previously labeled ‘Allow inrush current’)
10.2.3. AC Voltage Connection and Disconnection
Voltage limits at which feedback relay opens/closes.
These are the limits at which the unit will accept or reject the supply. If the input voltage drops below the set value of the lower
limit, the charger output will be reduced to the minimum to prevent further reduction of the voltage.
