How to properly report a problem?

In the message or form, please provide:

  • the address of the installation,
  • the name and surname of the installation owner,
  • a contact phone number,
  • the date the problem occurred,
    a detailed description of the symptoms,
  • the name of the device affected, if visible,
  • the error message or error code,
  • screenshots from the app or photos of the inverter, meter, or switchboard,
  • information on whether the problem is persistent or intermittent.

A well-prepared report significantly shortens the time needed for verification. In many cases, based on the information provided, we can determine whether the problem requires remote diagnostics, a settings update, or an on-site technician visit.

Please describe the issue in as much detail as possible and attach photos or screenshots, if available. This will help our support team investigate your request more quickly.

Before you need help from a technician, check out these few steps that can help you fix the most common problems yourself.

What should you do before submitting a request?

Before contacting service, it’s worth checking whether:

  • there’s an error message displayed on the inverter or in the app,
  • the system has internet access if monitoring is online,
  • there hasn’t been a power outage or a temporary grid failure.

Please do not disassemble the devices or attempt to repair the system yourself. A photovoltaic system is an electrical installation, and all service work should be performed only by qualified personnel.
