If an issue is detected via the Enlighten monitoring platform, please contact Enphase Customer Support. If the issue is related to the microinverter, Enphase will provide any service required under their warranty coverage. If Enphase determines the issue is related to the panel, the service will be transferred and supported by Maxeon Solar Technologies under the appropriate SunPower panel line warranty.

Your system will automatically shut down. Safety requirements prohibit the system from producing electricity during a power outage or blackout, because there is a chance that the system could feed electricity into the electric grid while utility workers are accessing the grid. The system will restart automatically when power is restored.

With a string inverter there is a single point of failure. If the string inverter fails, the entire array is offline. However, with a microinverter each individual PV module has its own dedicated inverter. If the microinverter (or the associated PV module) should fail. only that PV module is offline while the remainder of the system continues to operate.​ Enphase microinverters have a publicly stated defect rate of 0.05%, which equates to 1 in 2000. Given that the Enphase defect rate is better than most string inverters, this results in a PV installation with higher reliability and a higher overall system uptime over the life of the array.

Additionally, Enphase microinverters have an estimated useful life of more than 25 years, compared with string inverters that typically last around 10 years.

When sunlight strikes a solar cell, it dislodges electrons from atoms, creating an electric current. Connectors on the cell's positive and negative sides form an electrical circuit. This flow of electrons generates electricity. Solar panels consist of numerous cells, and you can connect multiple panels to create a solar array. The greater the number of panels you use, the more energy you can produce.

A photovoltaic (PV) solar system is comprised of solar panels, racks for placing the panels on your roof, electrical wiring and an inverter. From sunrise to sunset, the solar panels generate electricity (DC) which is sent to an inverter. The inverter converts the DC electricity into alternating current (AC), which is the type of electricity required for household use. The AC power is delivered directly to your home’s main electrical service panel for use by you and your family.

PV solar panels are like puzzles made of tiny solar cells, enclosed in glass. These cells are made of silicon, a bit like computer chips. They have a positive part and a negative part that work together to make electricity, kind of like a battery. SunPower solar panels also have special adhesives and coatings to protect these cells and keep them working well even in different weather conditions.
