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 Enphase APIs, however, Enphase does not currently offer products that re-direct surplus power.​

How do solar panels work?

When sunlight strikes a solar cell, it dislodges electrons from atoms, creating an electric current. Connectors on the cell's positive and negative sides form an electrical circuit. This flow of electrons generates electricity. Solar panels consist of numerous cells, and you can connect multiple panels to create a solar array. The greater the number of panels you use, the more energy you can produce.

What are Solar Panels Made of?

PV solar panels are like puzzles made of tiny solar cells, enclosed in glass. These cells are made of silicon, a bit like computer chips. They have a positive part and a negative part that work together to make electricity, kind of like a battery. SunPower solar panels also have special adhesives and coatings to protect these cells and keep them working well even in different weather conditions.

What is the MOQ for each cells and interconnection tabs (Purpose is to string the cell together)?

  • Maxeon Gen 3: 1500pcs/box
  • Maxeon Gen 5: 1200pcs/Box
  • Interconnection tabs:1200pcs/box

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 offline. The remainder of the system continues to operate as normal – a key benefit of AC modules.​

How long does charging take?

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.
