Frequently asked questions

General

Can I use SolarAssistant without a Raspberry Pi?

No. The software is designed only to run on a Raspberry PI. Once it's running on a Raspberry PI it can be accessed from Windows, Mac, Android, iPhone, etc.

Can I plug a screen into the PI or install additional apps?

No. Some users expect that when they plug a screen into the PI they will get a desktop such as the Raspberry Pi OS desktop. Our SD card image is a very minimal image that does not output anything to a screen. SolarAssistant is only intended to be used as a network device similar to your internet router. It is designed to be a robust monitoring system instead of a general computing device. It is optimized to run continuously for years while using the SD card very sparingly so that it can last for a decade.

Can I monitor multiple inverters with a single PI?

Yes, but only if the inverters are installed as a parallel installation.

Licensing

Can I use multiple PIs with a single license?

No. The license is a single device license aimed at monitoring a single solar installation.

Do I loose my license if I reflash the SD card?

No. If you reflash the SD card and insert it into a previously activated PI it will activate again without requiring a new license. It will also restore the URL you entered during registration (example my-solar.xx.solar-assistant.io) with all previous user access.

Can I move my SD card to a new PI to move the license and site registration?

No. When the SD card is inserted into a new PI it will show as unactivated. Additionally it won't move the URL you registered or user access to the new PI. For a new PI you have to reflash the SD card and perform a new registration/activation.

I have a hardware problem with my PI board and want to transfer the license to a new PI

Although our license is a single device license, the system will allow you to transfer your license to a new PI once. PI boards are extremely reliable and it's very unlikely that you would ever need more than one transfer. If you need to transfer your license, please contact us.
