Frequently Asked Questions
Is the AC module compliant with RD 244 for zero injection? Can it be used for isolated installations?
No, export limiting functionality is not yet compliant with RD 244/2019.
Most installations with Enphase are residential scale (below 15kW) and are easily accepted without this compliance.
In three-phase installations, can you divide surpluses by phases?
Each microinverter is a single phase device. Three-phase installations are constructed with single phase microinverters distributed across the phases. The export limiting will monitor power consumption at each phase using the CTs connected to the Envoy-S and limit power production on each phase accordingly to limit export to the grid to the defined level, either on a per phase or aggregate basis as required.
How is surplus solar production controlled?
Enphase offers export control by reducing power production at each microinverter to maintain export to a defined power level which can be zero for a zero-export site. It does not offer control of surplus power that cannot be exported to the electricity network.
Can you schedule the surpluses in any way? For example, to different appliances or an electric car charger?
Some customers have achieved some clever customised DIY solutions for re-directing surplus power using our APIs, however, we don't currently offer products that re-direct surplus power.
How has the system performed in high summer temperatures in Spain?
A simulated PV system performance has been evaluated in Madrid with the following results for roofs with limited space available:
- 30% more power on the roof
- 42% higher performance
- Half the degradation
- Covered by a longer, 25-year warranty
In a space unconstrained situation also in Madrid:
- 10% higher yield
- Half the degradation
- Similar cash flows
- Lower risk for future maintenance
- Covered by a longer, 25-year warranty
For assumptions and a personalized simulation, please contact us to be connected to a SunPower installer.
In a three-phase installation of 230V between phases, can these modules and microinverters be installed without additional transformers? What accessories need to be included in the installation?
Yes, AC modules can be installed on Delta grid arrangement with 230V between phases. No additional transformer equipment is required for typical LV connections.
Alongside the microinverters that are supplied as part of the PV module, installers will need to purchase Q cable, cable accessories and an Envoy-S.
Contact your Sales Manager to access additional installer tools to learn more about site design and balance of system requirements.
In addition to the AC module, what additional components are needed to complete the installation?
In addition to the AC module, installers will need to purchase Q cable, cable accessories, and an Envoy-S.
Contact your Sales Manager to access additional installer tools to learn more about site design and balance of system requirements.
How can is a system fault detected?
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.
If an issue is identified, does the installer need to replace the entire panel?
No, the microinverter is detachable from the PV module so each component can be serviced separately.
If a replacement is needed, who will provide the service?
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 SunPower Complete Confidence warranty.
How is the system managed in three-phase? How are imbalances managed?
The Enphase three-phase Q CableTM allows management of the power on the phases in a balanced and automatic way. Alternatively, 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 can also provide phase imbalance monitoring to ensure authorized limits are not exceeded. The Envoy is able manage PV power production at the microinverter level to maintain balance within set limits.
How many microinverters can you put on a single and three-phase installation?
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.
If one panel fails, does the rest of the system continue to produce energy?
If the microinverter (or the associated PV module) should fail only that PV module is off and the remainder of the system continues to operate as normal – a key benefit of AC modules.
Is this system compatible with storage solutions? What kind of storage?
AC solutions are compatible with AC energy storage solutions. When using Enphase Storage, you can see the energy flows on Enlighten. If you choose another brand, you will need their application to see the energy flows of the battery.
How is using multiple microinverters more reliable than using one string inverter?
With a string inverter there is a single point of failure. If the string inverter fails the entire array is off line. 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 and 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 that most string inverters, this results in a PV installation with higher reliability than with most string inverter solutions and a higher overall system uptime over the life of the array.
Additonally, Enphase microinverters have an estimated useful life of more than 25 years, compared with string inverters that typically last around 10 years. String inverters generally require replacement at least once within the lifetime of the PV array and duration of the PV module warranty.
What is the advantage of the AC modules in comparison to optimizers?
The SunPower Maxeon 5 AC solution offers higher yield, easier and faster installation, and greater flexibility. There are also other advantages such as reliability, shading advantage and low-light power responses.
Is the AC module system certified to this standard?
All grid-connected modules with integrated inverters must comply with all the requirements and tests established in parts 1 and 2 of the UNE-206007 Report. Prior to the connection and/or contracting of self-consumption, and as indicated in section 4 of part 2, this compliance must be certified by a certification body accredited according to UNE-EN 1S0/IEC 17065. Is the AC module system certified to this standard?
