If the microinverter (or the associated PV module) should fail, only that PV module is offline. The remainder of the system continues to operate as normal – a key benefit of AC modules.
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.
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.
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.
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.
No, export limiting functionality is not yet compliant with RD 244/2019. Most installations with Enphase microinverters are residential scale (below 15kW) and are easily accepted without this compliance.
Each microinverter is a single phase device. Three-phase installations are constructed with single phase microinverters distributed across the phases. The inverter will monitor power consumption at each phase using the CTs connected to the Envoy-S communications gateway, limiting grid export to the defined level, either on a per phase or aggregate basis as required.In three-phase installations, can you divide surpluses by phases?
