7.1 Checking the Function of the SMA Power Balancer and
Setting the Operating Mode
Requirements:
☐ The inverter must be equipped with a communication interface.
☐ A communication product, data logger or software appropriate for the type of communication
used must be available.
☐ The responsible network operator must approve changes of grid-relevant parameters.
☐ SMA Grid Guard code for changing grid-relevant parameters must be available (to apply for
an SMA Grid Guard code, see Certificate "Application for SMA Grid Guard Code" at
www.SMA-Solar.com).
1. Open the user interface of the data logger or software.
2. Enter the SMA Grid Guard code.
3. For all three inverters, select the parameter PowerBalancer or PowerBalancer operating
mode and set it to PhaseGuard.
4. Check whether all inverters display the message Mode MPP and whether the green LED of the
inverters is glowing.
If all inverters display the message PowerBalance, check the connection of the
SMA Power Balancer.
If the connection is correct and the problem persists, contact the SMA Service Line.
5. Switch off the miniature circuit-breaker of 1 inverter.
☑ The inverter with the deactivated miniature circuit-breaker displays the message Vac-Bfr and
disconnects from the electricity grid.
☑ The other two inverters display the message PowerBalance and also disconnect from the
electricity grid. They then display the message Balanced.
✖ The inverters do not disconnect from the electricity grid?
The connection of the SMA Power Balancer is probably faulty or the parameter
Power Balancer is not set to PhaseGuard.
• Check the connection and setting of the SMA Power Balancer. If the connection is correct
and the parameter PowerBalancer is set to PhaseGuard, contact the
SMA Service Line.
6. For all three inverters, select the parameter PowerBalancer or PowerBalancer operating
mode and set the required operating mode (description of the operating modes of the
SMA Power Balancer (see section 4.5)).
7. Switch the miniature circuit-breaker.
