If you're experiencing concerns about your RV's solar performance, the first step is to review your system data in the VictronConnect app. The app provides valuable information that can help determine whether your solar system is functioning properly and identify potential causes of reduced charging performance.

Understanding Your Solar Data

Solar Wattage is how many watts are coming in right now ( volts x amps).
Solar Voltage is the solar panel’s current voltage output.

Solar Amperage is the solar panel’s current amp output.

Battery Voltage is the battery’s current voltage reading.

Battery Current  is how many amps the solar controller is putting into the battery.


Reviewing Historical Performance

The History section of the VictronConnect app can provide additional insight into how your solar system has been performing throughout the day.
Yield is how much total solar energy we got each day.

P Max is the maximum recorded wattage output for that day.

V Max is the maximum recorded solar panel voltage   for that day.
Battery Max is the highest recorded battery voltage for the day.

Battery Min is the lowest recorded battery voltage for the day.


Using the Data to Diagnose Solar Performance

Reviewing these values together can help determine whether your solar system is operating normally.


For example, you may notice that both the Yield and P Max values are relatively low. At first glance, this could appear to indicate a solar issue. However, if the Battery Min value never dropped below approximately 13.4V, it may simply mean the battery remained nearly full throughout the day.
When batteries are fully charged, the solar controller limits charging because there is little or no additional energy needed. In this situation, low Yield and low P Max readings do not necessarily indicate a problem with the solar system.


The same scenario can occur when your camper is connected to shore power. While plugged in, the converter is typically maintaining the batteries at full charge. Since the batteries do not need additional charging, the solar system has very little work to do and may show lower output values than expected.


Before Assuming There is a Problem

  • When evaluating solar performance, consider the following:
  • Was the battery already fully charged?
  • Was the camper connected to shore power?
  • Was the camper parked in direct sunlight?
  • Were the solar panels free of debris, snow, or heavy shade?
  • What do the historical Yield, P Max, and Battery Min values indicate?
Looking at the complete picture rather than a single data point will help you determine whether the solar system is operating normally or if further troubleshooting is needed.

If your solar panels are in direct sunlight, the batteries are not fully charged, and the VictronConnect app still shows little or no solar production, additional troubleshooting may be required. Contact your dealer for further testing or contact us at tech@nucamprv.com.
