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 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?
How many microinverters can you put on a single-phase installation? And a 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.
What happens during power outages?
Your system will automatically shut down. Safety requirements prohibit the system from producing electricity during a power outage or blackout, because there is a chance that the system could feed electricity into the electric grid while utility workers are accessing the grid. The system will restart automatically when power is restored.
What is the typical cost advantage of using SunPower Performance panels?
Costs vary from project to project. Performance panels generally have a price point that is competitive with Conventional Panels.
How 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.
How does SunPower assist partners in reducing installation times and costs?
SunPower offers a unified commissioning process for all components, including warranty registration, which simplifies and accelerates installations. This efficiency not only reduces labor time but also minimizes costs associated with complex installations, enabling you to serve more customers effectively.
By partnering with SunPower, you can enhance your business's efficiency, reputation, and profitability through access to superior products, comprehensive support, and valuable resources.
