APsystems — Common Questions
What APsystems microinverters do you service?
We service APsystems YC500, YC1000, YC1000-3, DS3, DS3-L, DS3-H, QS1, and legacy YC250 microinverters, as well as APsystems ECU-B, ECU-C, and ECU-R communication units.
How often should an APsystems system be serviced?
We recommend an annual preventive maintenance inspection for APsystems systems. This includes a full ECU production scan, microinverter check, wiring inspection, and firmware verification.
My APsystems ECU shows offline microinverters — what should I do?
Offline microinverters in the APsystems ECU can indicate a failed microinverter, a wiring fault, a communication issue, or a grid/AC problem. We diagnose the root cause on-site and restore full production.
Can you service an APsystems system from a company that went out of business?
Yes. We service APsystems systems from any installer in Fresno County and Madera County. We can transfer the ECU account to your ownership and perform all maintenance and repairs regardless of who originally installed the system.
What is the APsystems microinverter warranty?
APsystems microinverters carry a 10-year warranty (extendable to 25 years with a warranty extension). If your microinverter fails within the warranty period, APsystems will provide a replacement unit — we handle the installation.
