How to install, configure and use the EPEVER PC software (2023)

There are many popular solar charge controllers from EPEver/EPSolar in the market, but the configuration and monitoring options are limited and complicated out-of-the-box. However, by connecting the charge controller to a PC, you get a lot of options.

EPEver / EPSolar charge controllers are usually just plug-and-play, and some, like the Tracer-BN series, comes without a display altogether. Although you can buy the MT50, a display with buttons that gives status and configuration options, it is quite cumbersome to work with.

How to install, configure and use the EPEVER PC software (1)

Luckily, you can connect most EPEver / EPSolar charge controllers to your PC (Windows only), and use EPEver's downloadable software to both do the configuration and monitoring. You don't have to keep the PC connected after configuration is done unless you want to monitor your solar charger(s) continuously. All you need to connect the charge controller to your PC is an RS485 to USB cable. This can usually be purchased from the same stores that sell the controller.

What does the charge controller monitoring data say?

First, congratulations, you have managed to connect your EPEver / EPSolar charge controller to your PC and is now able to both configure and monitor your solar power system easily.

To get some more space for the monitoring data, you may hide some not so useful sections.

How to install, configure and use the EPEVER PC software (6)

Select View(V) from the top menu, and uncheck both Tool Bar(T), Station Explorer and Message Window.

How to install, configure and use the EPEVER PC software (7)

The Solar Station Monitor "live" data

In the upper section, you have all the "live" data from the charge controller. Well, it's actually not completely live but is downloaded every few seconds from the charge controller. You can actually change how often the information should be refreshed, by changing the interval(s) value. The default value is every 30 seconds, which is just fine for most people.

The information is divided into four sub-sections:

(Video) Communicating with charge controller via your Pc

  • Solar Information
    • Solar Current (A): This shows how many Amps are currently coming from your solar panel or solar array (solar panels that are connected together). If you compare with the short circuit current or rated current on the back of your solar panel, you can get an impression on how much of the total capasity you're getting out of it at any given time.

      How to install, configure and use the EPEVER PC software (8)

    • Solar Voltage (V): The voltage that is coming from the solar panel.
    • Solar Power (W): To get the solar power in Watt, the software multiply Amps with Voltage; (A)*(V) = (W)
    • Solar Status
  • Battery information
    • Battery Voltage (V): The voltage of the battery. Normally a little above 12V when idle, up to 13.x when charging, but it should not drop below 10.8. However, the charge controller will turn off the load if the battery voltage drops too low, in order to protect the battery.
    • Battery Current (A)
    • Max Voltage (V): The highest voltage since the monitoring started.
    • Min Voltage (V): The lowest voltage since the monitoring started.
    • Battery Temp.: If you have connected a temperature sensor to your charge controller and placed in on the battery, this will show the current temperature of your battery. Should normally be around the same temperature as the surrounding air. A very hot battery can be a sign of a short circuit.
    • Battery SOC(%): State of charge. This percentage value has to be taken with a grain of salt. It's better to look at the battery voltage and the load wattage; It the load is low and the battery voltage is low, then the SOC is actually low. However, you might have a heavy low (also directly on the battery). If so, the battery voltage might drop as well.
    • Charging Status: Float charge, boost charge, or equalizing charge.
    • Battery Status: Notifies if something is wrong with the battery, but you might take it with a grain of salt. If you get an error, you may try disconnecting the battery from the solar charge controller, and put it on an "intelligent" 12V battery charger for a while to see if it takes charge.
  • DC Load Information
    • Load Current (A): The amount of current that is drawn through the load output of the solar charging controller.
    • Load Voltage (V): The voltage on the load output.
    • Load Power (W): Load Amp times load Voltage; (A)*(V) = (W)
    • Load Status
  • Controller Information
    • Device Temp.: The temperature of the charger. Under high charge and/or load, the solar charge controller will heat up, so make sure it has some airflow around it.
    • Device Status: Notifies you if the charge controller is okay, or if there is an error. In case of an error, try disconnecting both the solar panel and the battery connections, then reconnect to see if the error is gone.

In addition, you have the Load Control, where you can manually turn the power output from the charge controller on and off.

The solar station monitor graphs and statistics

In the lower section, you have some statistics and charts available. The charts are incremented as long as the monitoring is active, and you might want to clear the charts once in a while. You can do so by right-clicking on the chart, then select Clear.

In the left column, you have some key numbers of how much power your solar setup has generated; daily, monthly, annual, and in total. You also have the same numbers for power consumption through the controller load.

In the Real Time Curve sub-section, you have access to 3 different charts; Voltage, Current, and Power.

How to install, configure and use the EPEVER PC software (9)

The voltage chart shows the voltage development over time for both the solar panel, the battery, and the load. For some unknown reason, the battery curve does not show up in our setup.

How to install, configure and use the EPEVER PC software (10)

The current chart shows the Amperage curves for the solar panel, the battery (the current going from the controller and into the battery), and the load.

(Video) How to download and install "Solar Station" software

How to install, configure and use the EPEVER PC software (11)

The power chart is the most useful, in our opinion. It shows the wattage development for the solar panel and the load. Here, you get an impression of how well your solar panel setup is performing. In our setup, we use a 200W panel, but it's rear to have the wattage above 180W.

Changing the settings for the EPEver solar charge controller with the software

It's possible to do some tweaking of the settings on the charge controller with the solar station monitor as well.

How to install, configure and use the EPEVER PC software (12)

To enter the settings panel, select Parameters (P) > Control Parameter > Control Parameter from the top menu.

How to install, configure and use the EPEVER PC software (13)

Before you can change anything, you have to fetch the current settings from your charge controller. Click the Read button in the bottom left corner to download the current settings.

From here, you can change most of the parameters. However, be careful and know what you're doing; altering the settings can potentially damage the battery and equipment connected to the charge controller.

We have found that most of the default settings are just fine. But you might want to alter the battery type and battery capacity according to what you have connected to your solar setup.

Different load resistance is considered for maximum power point tracking (MPPT) with different converter topologies, and it has been observed that buck-boost converter is suitable for any load resistance connected in the PV system.

Which is the best MPPT technique? ›

In summary the best algorithms are those designed using the SASV-MPPT approach and Lyapunov de- sign method considering that the PV system can move from one characteristic to another. The proposed al- gorithms are the most efficient despite using low fre- quency commutation. They are the faster converging.

Can I connect a MPPT directly to inverter? ›

MPPT charge controllers help to flow the current efficiently into a depleted battery. If we connect an MPPT charge controller directly to the inverter, your system can get damaged, but if not damaged, there will be zero input in the inverter. So connecting MPPTs directly to the inverter is a bad idea!

Is higher voltage better for MPPT? ›

With MPPT, the total array voltage needs to be greater than the battery bank voltage, but it also uses that extra voltage to boost the amperage going to your battery.

What can damage solar battery? ›

About 80% of failures are caused by sulfation, a process where sulfur crystals form on the battery's lead plates and prevent chemical reactions from happening. Sulfation occurs when the battery has a low charge or electrolyte level.
