The solar inverter readings give you important info about the system’s performance and settings. In this guide, we will teach how to read a solar inverter display to help you optimize your PV setup.

How to Read Solar Inverter Display

Comprehending how to read your solar inverter display is essential for keeping a check on your energy usage. Here’s a simple guide to help you with the steps:

Step 1. Power Up

To begin, tap any of the four buttons located below the display to activate the backlighting and track the data.

Step 2. Access Main Menu

Press the MENU button to get to the main menu options.

Step 3. Check Total Energy Generated

Use the button on the right (second from the left) to access the Total option from the lists shown at the top of the inverter screen.

Step 4. Get Total Energy Output

Press the Enter button (far right on the screen) to view the entire energy generated or power output since the time of installation.

Solar Inverter Status Indications

Now, let us go through some statuses that may indicate issues with your solar inverter display:

1. Standby: The solar inverter display enters standby mode when it awaits enough solar radiation or battery charge to operate smoothly. This occurs when there is inadequate sunlight or the battery charge is relatively low.

2. Flash: The firmware of the inverter might be upgraded, causing the display to work in flash mode. This upgrade can be done remotely through a wireless communication system or performed locally through an RS485 communication connection.

3. Fault: In case of an inverter or system malfunction, it will display a fault message, and the inverter will stop its operation until the problem is resolved.

Moreover, in this guide to reading your solar inverter display, check out some additional indications to know how your inverter is operating.

  • PV Grid On: The inverter is working normally, and all the power produced by the solar panels is sent to the grid for general usage.
  • PV Charge: The inverter functions effectively, and all the power generated by the panels is utilized to charge the solar battery, with no extra power sent back to the grid.
  • PV Charge + Grid On: The inverter is functioning normally on-grid, and the surplus power is in stock to export to the grid while powering your connected devices.
  • AC Charge: The inverter is on-grid without solar input, and utilizes the grid power to recharge the battery, given this function is activated.
  • PV+AC Charge: The inverter is on-grid with limited solar input, with both these options available to recharge the battery- solar, and grid power.
  • Battery Grid On: The inverter runs on-grid with no solar input, hence relying on stored energy from the battery and sending power to your system through the grid.
  • PV+Battery Grid On: Here, exporting power occurs with both solar input and stored battery energy through the grid.
  • Battery Grid Off: The inverter works off-grid with no solar input, discharging the battery to power your devices through the UPS connection.
  • PV Battery Grid Off: Similar to the previous status, this refers to the indication only with limited solar input added to the battery discharge.
  • PV Charge Grid Off: The inverter functions off-grid with adequate solar input, recharging the battery with solar energy and sending extra energy through the UPS connection.

Thus, by understanding how to read solar inverter displays and inverter statuses, you can effectively monitor and optimize your solar energy consumption.

JAN23 How to Read Solar Inverter Display 1

When observing the display, you will see that the solar inverter readings alternate between positive and negative numbers. Here, the positive value refers to the amount of electricity you have drawn from the grid. However, inverter display meaning indicates information that describes your solar energy system. It talks about the amount of electricity your solar panels have been producing, measured in kilowatts (kW). You can also keep track of how many kilowatt-hours (kWh) of energy the system can generate on a regular basis since its installation.

There are some special inverters equipped with additional features, like displaying the total number of hours the system has been producing power. The display can be a single exclusive unit or accessible remotely through smartphones or computer systems. The solar inverter readings indicate valuable insights into the system’s performance and status. Thus the solar inverter display is very important as it shows numbers to denote wattage, voltage, feed-in current, and power generated as well. Moreover, when purchasing a solar inverter, consider its rating, which is given in terms of DC input and AC output. This rating helps you pick an inverter that suits your specific energy requirements.

Therefore, the inverter display provides you with vital information about your system’s performance, allowing you to monitor electricity generation and make informed decisions about energy consumption. Just make sure to buy the appropriate inverter based on its rating to meet your specific needs.

What Do the Lights Mean on My Solar Inverter?

Solar inverters usually have LED lights showing status and also come with an LCD display. These lights come in different colors (red, yellow, and green), to indicate the operating status of the system. Green light signifies that the system is operating, charging, or delivering power. In this way, LED lights allow you to monitor the performance without constant display checking.

However, if your solar inverter’s screen has no lights and is showing blank, there are two possible explanations for this:

1. No DC Power is Reaching the Inverter: First, make sure that the inverter is connected and turned on and that the DC isolator is in the ON position as well. If your inverter is equipped with switches for the DC (PV ARRAY MAIN SWITCH), ensure they are up, and check that the indicator lights below the breakers are red, not green.

2. The Inverter is Malfunctioning: If everything seems correct with the DC power, but the inverter remains inactive and unresponsive, it might be broken or have some faulty parts. In this scenario, try rebooting your system, but if the issue still exists, it is vital to seek guidance from a qualified and experienced solar technician. They have the necessary tools and expertise to detect and resolve the problems. They can also run a simple test to find out if there is DC power coming from the solar panels.

How to Restart a Solar Inverter Display?

Restarting a solar inverter is quite similar to restarting our smartphones. To restart the inverter safely, follow these steps:

  • Switch off the main switch (AC isolator) on the solar power distribution board.
  • Find the switch under the solar inverter display and power off the DC isolator. Hold for about 10 to 15 seconds until the system fully powers down.
  • Switch on the DC isolator first, and then turn on the AC isolator.
  • Allow a few minutes for the inverter to restart and start its operation.

In conclusion, reading the solar inverter display is a simple process. You can easily see the total power output produced since installation. By monitoring your system’s performance, you can make informed choices about your energy usage. For more interesting topics, feel free to explore our blogs.
