User Manual
Cause and solution
• The Sunny Beam is too far away from your Bluetooth PV system, or
the radio connection between the Sunny Beam and your Bluetooth
PV system is subject to interference. The reason for the interference
could be, for example, walls or ceilings which weaken the radio
waves.
– Place the Sunny Beam closer to a device in your Bluetooth PV
system. If this is not possible, use the SMA Bluetooth repeater to
bridge the radio gap.
• The message does not affect the functionality or speed of the Sunny
Beam.
– You can switch the message off, but then other USB error
messages will not be displayed. Proceed as follows. These steps
describe Windows XP and may be different in other operating
systems. Right-click on "My Computer" and select "Device
Manager". Open the "USB Controller" in the Device Manager.
Right-click on the item "Host Controller". Select "Properties". Select
"Advanced". Tick the box that says "Do not display USB errors".
• For PV systems with the SMA Bluetooth piggy-back, there will be
gaps in the charts if you have set a time on the Sunny Beam which
precedes detection of the PV system in the Sunny Beam. Extreme
characteristics will appear in this case, if you have reset the time.
The reason for this is that an inverter saves the generated data
together with the current time. The Sunny Beam will retrieve these
data from the inverter and display them.
– Do not change the time settings on the Sunny Beam more than
necessary.
