In single-phase, 10 microinverters can be connected. In a three-phase installation, up to 30 microinverters can be connected on a single 20A three phase circuit breaker. Larger systems can be constructed with multiple AC branch circuits.

The Enphase three-phase Q Cable allows balanced and automated power management of each phase. Alternatively, when using three single-phase cables, care must be taken to balance the phases by installing a similar number of panels on each phase.

The Envoy-S communications gateway can also provide phase imbalance monitoring to ensure authorised limits are not exceeded. The Envoy is able to manage PV power production at the microinverter level to maintain balance within set limits.

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.

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.

You can power your entire house using solar energy. By installing solar panels, you can generate electricity from sunlight and run your home's appliances, lighting, and other electrical systems. An inverter converts the solar-generated electricity into a usable form, and batteries can store excess energy for use during cloudy days or at night. Factors like your energy consumption, the size of the solar system, available sunlight, and location are all important. Our professional installers will help you determine the right setup for your needs.
