Solar panels can be a worthwhile investment, especially in regions with abundant sunlight and favorable incentives. They offer numerous benefits, including cost savings on electricity bills, reduced environmental impact, and potential increases in property value. Solar panels typically pay for themselves over time through energy savings and potential government incentives, making them an attractive option for many homeowners and businesses interested in sustainable energy solutions and long-term financial benefits. The return on investment, however depends on factors like your energy consumption, location, available incentives, and long-term goals. That's why we recommend to conduct a thorough evaluation and consult with one of our solar professionals to determine the specific economic and environmental advantages for your situation.

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?

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.

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.
