SMA inverters

Driftwind Electrical can assist you with any SMA warranty issues. We will need the fault code and serial number to lodge an insurance claim. Some faults will require testing prior to lodging the claim, though. We recommend adding a health check to the attendance to ensure that there are no underlying issues with your installation. SMA has the fastest industry response to warranty claims with a response time of about 5 working days.

If your SMA inverter is out of warranty, you will need to purchase a new inverter in the closest possible size. SMA inverters are transformerless inverters, so Growatt, Zeverlution and Fronius are all compatible. Some faults, like varistor failure, can indicate a surge has occurred and can therefore be covered by insurance, although, sometimes, the cost of repair is less than the excess, depending on your policy.

See below for the error codes recognized with your SMA inverter/solar system.

If you are still unsure call us to see if we can help you over the phone, or book in a Solar Health check.
You could save big $$$’s with one of our Solar accredited teams expert appraisal. 
If you believe that your Inverter may be subject to an Insurance claim please contact us on 07 3274 4365 and advise us of the details

COMMON SMA ERRORS

FAULT CODE	DESCRIPTION	REMEDY
Derating	Over temperature	Derating refers to overheating and will often require a replacement inverter if outside of warranty, or a repair if within warranty.
Disturbance	No grid connection	Disturbance is a utility issue, which means it pertains to an AC issue. You should check the AC isolator below the inverter and the switch labelled “AC solar supply” in the switch board. The inverter may need replacing.
Error	Internal Fault	Error codes represent an internal error and will likely need to proceed with a warranty claim or, if out of warranty, a replacement inverter will need to be purchased.
Grid Mon	Grid Monitoring	This message will appear during start up and shut down. If it occurs at midday, the inverter may need replacing.
MPP	MPP Mode on	This is not a legitimate error and the inverter should still operate with this fault being displayed.
Off Grid	System Islanding	The inverter will need to be replaced.
Offset	Measurement	This code does not indicate a fault.
Riso	Insulation Resistance	A technician will need to attend in order to test the panels and the balance of system (BOS).
Stop	Interruption of operation	Check the solar supply main switch. The inverter may need replacing.
V-Const	Constant voltage operation	This code does not indicate a fault.
Waiting	Switch on conditions not met	This message will appear during start up and shut down. If it occurs at midday, the inverter may need replacing.
vac-BFR	GRID ISSUE	Check the solar supply main switch. The inverter may need replacing.
Varistor Failure		A varistor failure is indicative of a surge and is not covered by warranty. It is repairable for a fee.
