AC solutions are compatible with AC energy storage solutions. When using Enphase Storage, you can see the energy flows on Enlighten, Enphase’s system monitoring application. If you choose a different storage solution provider, you will need to use their monitoring application to see the energy flows of the battery.​

A photovoltaic (PV) solar system is comprised of solar panels, racks for placing the panels on your roof, electrical wiring and an inverter. From sunrise to sunset, the solar panels generate electricity (DC) which is sent to an inverter. The inverter converts the DC electricity into alternating current (AC), which is the type of electricity required for household use. The AC power is delivered directly to your home’s main electrical service panel for use by you and your family.

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.

This will depend on your panel wattage, your battery watt-hour (Wh) capacity (a measurement of storage capacity) and the weather. A 150 Wh battery will charge faster than a 500 Wh battery because the 500 Wh battery has more storage capacity, therefore requiring more time to fully charge. In addition, a 100-watt panel will charge a battery faster than a 50-watt panel exposed to the same amount of sunlight.

Charging time will be affected by weather, shade, time-of-day, age and use of battery, efficiency of the charge controller, placement of the solar panels, and other operational factors. Be sure to look on your solar-compatible battery for an estimate of charging times as well as panel-wattage compatibility, and always check the charging characteristics of the battery to ensure it’s compatible with the wattage of the panel.

For higher battery capacity (greater than 150 Wh) we recommend using a 100-watt panel. Before doing this, however, please ensure that the battery you are charging is compatible with this wattage and use a compatible charge controller.

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?
