The float stage starts when the batteries are 100% full. During the float stage the charge current is very low.
To find out what the state of charge (SoC) of the battery is, check the battery monitor (if present), or alternatively, check the
charge stage the Orion XS is in.
• Bulk: 0-80% SoC
• Absorption: 80-100% SoC
• Float or storage: 100% SoC
5.2.4. Battery cable voltage drop
If there is a voltage drop over the battery cables, the Orion XS will output the correct voltage, but the batteries will receive a lower
voltage. Battery charging will take longer, potentially leading to undercharged batteries.
In case there is a large voltage drop, the battery cables and cable connection will need to be checked, and if there are issues,
they will need to be rectified.
The voltage drop can have the following causes:
• Battery cables with insufficient cross-sectional area
• Badly crimped cable lugs or terminals
• Loose terminal connections
• Bad or loose fuse(s)
Battery cable voltage drop check
This check can only be performed if the Orion XS is in the bulk charge stage and is charging with full current.
1.
Measure the voltage on the battery terminals of the Orion XS using the VictronConnect app or a multimeter.
2.
Measure the battery voltage on the terminals of the battery using a multimeter.
3.
Compare the two voltages to see if there is a voltage difference.
5.2.5. Temperature difference between Orion XS and battery
It is important that the ambient temperatures of the battery and the controller are equal. The Orion XS will measure the ambient
temperature at the start of the charge cycle and assume it is the same as the battery temperature. It will then adjust the charge
voltage based on this temperature measurement and its compensation setting.
Once the Orion XS goes into float stage, it will measure the ambient temperature again and will use that measurement to adjust
the voltages again.
If there is a large ambient temperature difference between Orion XS and battery, the battery will be charged at the wrong
voltages.
