How to Read Solar Inverter Display?

Solar inverters are becoming more and more common in our lives, especially today when we tend to live off the grid and clean energy.

The main function of a solar inverter is to convert the (direct current) DC electricity stored in the solar battery into AC electricity for household appliances use.

Advanced solar inverters and controller inverters are widely used in homes, RVs and camping solar power system.

Solar inverters usually come with an advanced multi-function screen to help us understand how the system works and its current status, as well as to set system parameters and identify current system faults.

If the display is turned off, you can turn it back on by pressing the HOME/Power button on the dashboard.

This topic will help you get the most out of the information that appears on the solar inverter display.

The display will light up for a period of time after the system is turned on or operated, and then the display will automatically turn off.

If the display is turned off, you can turn it back on by pressing the HOME/Power button on the dashboard.

The Solar Inverter Display

The solar inverter display refers to an LCD screen on the device body.

The solar inverter display gives you some insight into whether the solar inverter is working and its working status.

Due to the limited size of the inverter screen, the display requires several screen/page levels to show all the information,

The first screen shows the two main operating parameters of the system: battery voltage and output voltage, and is the information displayed when the inverter is switched on.

the display is very simplified and hides a lot of the interesting complexities of the solar inverting. nevertheless, you know what the display is telling you.

The first thing you will see on a solar inverter screen is the battery voltage and the system output voltage, which are located at the top.

The glowing “battery” symbol reminds you of the battery voltage and the 110V/220V output voltage reminds you of the output voltage.

Below the battery and output you will find the whole system diagram with flowing arrows, which tells you the real time working status of component in the solar system.

some premium solar inverters support remote display, you can control and settings via APP or PC software.

How to Read Solar Inverter Display?

system’s performance and settings are what we use with the LCD display.

In the first screen you will find the battery icon with voltages and the power output icon with voltages (115V/220V).

Below the battery and the outputs you will find the operating diagrams of the whole solar pv system, including the solar panel, the solar inverter, the solar battery and the loads.

Use the up and down buttons and the ‘Enter’ option to access the various components to view their detailed status and set their parameters.

Solar Panel

Once inside, you can view the parameters of the currently connected solar panel. These include wattage, real-time voltage, how much energy has been generated (in kilowatt-hours) and real-time current.

You will also be able to see whether the panel is charging or not.

Solar Inverter

Solar inverters are used to convert DC power to ac power in a solar system.

There are two types of solar inverter, a stand-alone inverter and an all-in-one solar charge controller inverter with integrated controller function.

The stand-alone inverter displays the current operating status of the inverter’s inputs and outputs, including real-time voltage and current.

all-in-one solar charge controller inverter both working as a charge controller to charge the solar battery, and convert the Solar energy and battery energy to power home appliance.

in the hybrid solar inverter display, you will see both the charging and discharging status of the inverter.

Solar Charging

Solar inverter with mppt charge, also with charge settings and status page.

The charge settings are the same as for the mppt solar controller, setting the battery type and volts, charge voltage and full cut-off voltage.

The charge status shows the total power generated, the charge voltage and current and whether the battery is being charged.

Solar Battery

Once on the solar cell page, you will see the current battery level, voltage status and the amount of electricity that has been charged.


Loads refers to the device connected to the current inverter, go to the loads page and you will see the daily total energy consumption (kwh) and usage time of the current device.

Faults/Error Codes

error codes are short terms to indicate an error or malfunction.

error messages helping the user with intuitive troubleshooting.

If you have a solar PV system, it is important to be aware of the various faults and error codes that may occur.

The solar inverter will give an indication in the display when something goes wrong. For example, if there is a problem with either the solar panel or with your wiring, you will see an error code such as ‘PCF’. This indicates that power has not been able to reach the load due to some kind of obstruction. In this instance, it might be necessary to consult a professional installer or electrician in order for them to rectify the issue

Once you have finished viewing or setting up, you can exit the current screen using the “ESC” button.

What do the numbers mean on an inverter?

There are many numbers on the solar inverter, usually near an icon such as Panel, Battery, Inverter or Load.

The numbers near the panel or at the panel interface are usually the watt of the solar panel, the voltage,feed-in current and amount of power generated.

The numbers near the battery or on the battery interface are usually the voltage, current and state of charge of the battery.

The number near the inverter or on the interface is the output voltage.

The numbers near the load are the wattage and voltage of the current load.

How do I read solar inverter specifications?

There is no one definitive answer to this question since solar inverter specifications can vary depending on the particular model and size. However, Almost all of the parameters are common, although they are placed in different places..

For example, many inverters use a power factor correction (PFC) algorithm in order to improve your output voltage while reducing AC noise or ripple. You may also see a module voltage, current or wattage rating listed. This indicates the maximum possible output power that the inverter can produce under specified conditions.

To read more specific information about an inverter specifications, consult to an user manual by the inverter manufacturer.

How do you check an inverter reading?

you can check an inverter reading by the LCD screen or by a remote monitor.

almost all inverters have a an “Info” button or screen that will show detailed information about the output voltage, power consumption and voltage regulation of the inverter.

What do the lights mean on my solar inverter?

In addition to the LCD display, almost all solar inverters have LED status Lights, which usually have several states, such as red, yellow and green, to indicate the operating status of the system.

This allows you to see how the system is performing without having to look at the display,

For example, a green light usually means that the system is operating, charging or that the inverter is delivering power.

The lights on your solar inverter will indicate how much power the inverter is currently generating (wattage), how much power your current load is drawing and whether or not the system is within tolerance parameters.

How often should I read my solar inverter display to make sure everything’s working correctly in my house?

You should usually read the solar inverter display every 2-4 weeks to make sure everything is working correctly.

Which type of solar inverter display should I get for my home?

If it is not convenient to view the current solar inverter display, you can purchase a remote screen, Bluetooth component or Wifi component and use the app to view it via Bluetooth or the internet.
