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.
SunPower AC solutions offer higher yield, easier and faster installation, and greater flexibility. There are also other benefits such as reliability, shading advantages and low-light power responses.
All AC module installations must be Internet connected for the monitoring to receive the 25-year microinverter warranty. This Internet connection reports data to the Enphase monitoring platform, Enlighten on a per microinverter/module basis. The performance of each microinverter and module is visible to the installer via Enlighten and alerts are provided for any faulty equipment, such as an under-performing PV module or a faulty microinverter.
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.
