Where does my inverter data go?


It can be useful to understand how data gets from your inverter to the outside world. Let's take a look at the steps involved:

  1. First, a measurement is made by the inverter, and this data is sent to the logger to be transmitted.
  2. The logger communicates with a cloud-based server*. Your logger needs to be connected to the internet for this to work, typically via a Wi-Fi connection to a Wi-Fi router.
  3. Data remains stored in the cloud to be accessed by you via Versofy HOME (alternatively Sunsynk or Solarman app). It is also used by Versofy's automated systems, and made available to our support and monitoring personnel.


What is meant by inverter data?

Inverter data includes any measurement that is made by the inverter, or devices connected to it. Examples of this are:
  1. Battery state-of-charge (battery percentage)
  2. Battery charging or discharging power
  3. Inverter temperature
  4. Grid information (power, phase, etc.)
  5. And many other metrics.

Where does inverter data eventually get used?

There are three main places where your inverter data is used.
  1. Monitoring via the Versofy HOME app (alternatively the Sunsynk or Solarman apps). This is what allows you to keep an eye on the performance and operation of your system in real time from anywhere.
  2. Support and technical personnel at the Versofy HQ. For example, when you report an issue with your system, this data is used to help analyse and diagnose the problem.
  3. Automated monitoring and optimisation. One example here is the "Smart Automatic" feature of Versofy HOME, which makes use of historical inverter data to determine production and consumption patterns.

Troubleshooting

Occasionally, things can go wrong with the process of transmitting inverter data. If this happens, your monitoring app will report that your site is offline, or simply show no data, and Versofy will be unable to remotely monitor your solar system.

Internet connection

Make sure that the internet connection of your router itself is working. This can be confirmed by trying to access the internet from any device connected to the same Wi-Fi network.

Connection between logger and inverter

Make sure the logger is properly connected to the inverter. The picture below shows an example of a powered logger, with LEDs lighting up. If there are no lights, this could mean that your logger was somehow disconnected.




Wi-Fi connection between logger and router

During installation, your logger will have been set up to connect to a Wi-Fi network. However, this connection can be broken if:
  1. Your Wi-Fi password is changed.
  2. Your Wi-Fi network name (SSID) is changed.
  3. A logger is replaced with a new one.
  4. Your Wi-Fi router is upgraded or replaced.
  5. Something went wrong during a firmware update on the logger or inverter.
If you suspect any of the above might have happened, you can follow the instructions below, depending on your inverter brand:
  1. App Offline (Sunsynk System) - How to reconnect
  2. App Offline (Deye System) - How to reconnect
Connecting your logger to a Wi-Fi network can be complicated. The Versofy support team can assist with this if needed.

*A number of servers may be involved in this process, including those operated by equipment manufacturers like Sunsynk or Solarman, or servers run by Versofy ourselves.
