Fronius — Common Questions
How often should a Fronius inverter be serviced?
We recommend an annual preventive maintenance inspection for Fronius inverters. This includes an error code check, firmware verification, Solar.web monitoring review, and production baseline comparison. Annual service catches issues before they affect your PG&E true-up.
What does a Fronius firmware update do?
Fronius firmware updates improve inverter efficiency, fix known bugs, and patch security vulnerabilities. We update your Fronius inverter to the latest firmware release during a service call and verify production is normal afterward.
My Fronius Solar.web shows no data — what is wrong?
A Fronius Solar.web showing no data usually means the inverter has lost its connection to the Fronius server. This can be caused by a Wi-Fi change, a router replacement, or a Datamanager module failure. We diagnose and restore monitoring connectivity on-site.
Can you service a Fronius system from a company that went out of business?
Yes. We service Fronius systems from any installer in Fresno County and Madera County. We can transfer the Solar.web account to your ownership and perform all maintenance and repairs regardless of who originally installed the system.
What is the Fronius inverter warranty?
Fronius inverters carry a standard 10-year warranty, extendable to 15 or 20 years with a warranty extension. If your inverter fails within the warranty period, Fronius will provide a replacement unit — we handle the installation and commissioning.
