System Connectivity & Monitoring FAQs
Enphase App Method: Use the Enphase Homeowner App to follow the guided reconnection steps.
Manual Method: Press button 2 on the Envoy to turn on the access point, connect your phone to the “ENVOY-XXXX” Wi-Fi network, and follow the manual configuration instructions.
Ensure your home modem/router is online and cables are secure.
Power cycle the ECU by turning it off for 30 seconds and back on.
Ensure the ECU is plugged directly into a wall outlet, not a power board or extension cord.
If troubleshooting, try different wall outlets in different rooms for at least one hour and monitor if the LCD screen displays a value other than “000”.
It is typically a small rectangular unit mounted near the main switchboard, in the garage, or on an internal wall near the meter box.
Battery Troubleshooting (POWERBANK) FAQs
- Hold the silver button on the battery module until LED lights turn off.
- Switch the BMS breaker to OFF.
- Switch the AC mains/battery grid supply breaker OFF and wait for all BMS lights to turn off.
- Wait 2–3 minutes, then reverse the process (AC ON, then BMS breaker ON, then press silver buttons).
- Fault State: Stops system operation and often requires a reboot, firmware update, or technician.
- Protection State: A self-recovering state triggered when internal or external parameters (like voltage) are exceeded.
Press the battery button 10 times until the LED perimeter remains solid red; this helps recover batteries with critically low SOC.
There is no communication between the Battery Management System and the Energy Management System. This can often be fixed by pressing the battery button to turn the BMS back on.
Installation & Performance (CT Issues & Shading) FAQs
This is usually caused by the Grid CT not communicating or reading “0,” preventing the battery from charging or discharging.
Solar export will be seen as consumption (charging the battery at night) and grid consumption will be seen as export (discharging in the day), which can be costly.
If system diagnostics show microinverters and DC outputs are normal, the cause is often local shading from trees or structures, which can be confirmed if power drops at different rates across panels.
Warranty & Support FAQs
REA Power provides a 25-year Limited Product Warranty and a 30-year Limited Power Warranty.
IQ8 microinverters typically carry a 25-year warranty from the activation date.
Commonly Asked Questions
Understand solar energy terms such as watt and watt-hour
Knowing the difference between a watt (W) and a watt-hour (Wh) helps you understand the impact of your home energy use on your electric bill. You can also compare your home energy use to the energy generated with your REA Solar microinverter system. Read on below.
While watts and watt-hours are related terms, they are not the same thing.
SO WHAT IS A WATT?
A watt (W) is a unit of power, and power is the rate at which energy is produced or consumed. Think of watts as a measure of electrical flow. Does an electrical device need a big flow or a small flow to work? For example, a 100 W light bulb uses energy at a higher rate than a 60 W bulb; this means that the 100 W light bulb needs a bigger “flow” to work. Likewise, the rate at which your solar energy system “flows” power into your home is measured in watts.
MyEnlighten displays your system’s latest and daily peak power generation in kW, which is equal to is 1,000 W.
SO WHAT IS A WATT-HOUR?
A watt-hour (Wh) is a unit of energy; it’s a way to measure the amount of work performed or generated. Household appliances and other electrical devices perform “work” and that requires energy in the form of electricity. Utilities typically charge you for electrical energy by the kilowatt-hour (kWh), which is equal to 1,000 watt-hours. Depending on your interconnection agreement, your utility may credit you for excess generation which will also be measured in kilowatt-hours.
MyEnlighten displays the amount of energy generated by your microinverter system in watt-hours. For example, an REA Solar microinverter system might generate 400 kWh (amount) in the month of September (period of time). A kilowatt-hour (kWh) is 1,000 Wh, so 400 kWh is 400,000 Wh. In some cases, MyEnlighten will display energy as megawatt-hours (MWh), which is one million watt-hours.
SO WHAT IS THE DIFFERENCE?
In a nutshell, watt-hours measure amounts of energy for a specific period of time, and watts measure rates of power at a moment in time.
A common analogy for watts and watt-hours is speed and distance. Speed is the rate of how fast you drive at an instant in time (watts); distance is the length, or amount that you drive over a period of time (watt-hours). For example, if you drive at a constant rate of 60 miles per hour for one hour, then you will have traveled 60 miles.
Similarly, if a 60 W light bulb is on for one hour, then that light bulb will have used 60 Wh of energy. If left on for two hours, then the 60 W light bulb will have used 120Wh of energy.
SO WHAT?
Knowing about watts and watt-hours can give you a greater appreciation of the energy savings on your utility bills. You can compare the electric bills you received before you installed your REA Solar Microinverter system to your current bills and calculate your energy savings, and in turn your monetary savings. Keep in mind that your utility will only bill and credit you for energy that runs through your electric meter. Solar generation that is consumed by your home will not be measured by your utility.
It is common for panels on the same roof to vary in energy generation. Many factors can cause these variations, such as panel direction, shading from chimneys or trees, and other obstructions.
Solar panels are “mismatched” directly from the factory and can vary. This is normal.
The solar panels that are being compared may not be on the same roof. In this case, they won’t receive the same amount of sun each day.
One of the panels may be obstructed or shaded for a part of the day. For example, a neighbor’s roof may shade lower panels for part of a day, or one panel may have the shadow from a vent stack come across it each day.
If one of your microinverters has been replaced, only the new unit’s production will be displayed. Data will be correct from when the new microinverter was installed, but you will no longer be able to see energy production from before the microinverter was replaced.
A solar panel in your array will be grey if no energy has been reported for the period you are viewing. The panel may not have woken up for the day; perhaps it is the last to receive the sun. Or the panel may be experiencing a communication disruption in reporting its data to your Envoy. When communications are restored, all the data from the period of the communication disruption will be reported and displayed. Snow cover will affect energy production and communication of microinverters.
