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?

Not all solar systems are created equal. Of all solar panels on the market, SunPower panels convert more sunlight into electricity. This means our solar panels generate more power than conventional panels1 within the same amount of space and you’ll need fewer solar panels to produce the energy you need. You can maximise your available roof space to choose the best, unobstructed location for electricity production. You'll save more money on electricity costs over time with SunPower.

Every single panel is electrically tested and inspected for cosmetic criteria at the end of the production line. Regardless of the cosmetic grade, the cosmetic effects do not affect performance or reliability.

We built the Performance solar panels for high reliability, high efficiency and low degradation—driving an estimated 8% more energy yield in a fixed space over the first 30 years of operation when compared to Conventional mono PERC Panels1.

SunPower® Performance solar panels use high efficiency mono PERC cells, while Maxeon panels use SunPower's proprietary back contact technology developed for our Maxeon panels.
