Caution

Working with high voltage is dangerous. Always follow local laws and regulations regarding high voltage work. If you are unsure about the rules in your country, consult a licensed electrician for more information.

Compatible SMA Sunny Island inverters

  • Sunny Island 4.4M (Testers wanted!)
  • Sunny Island 6.0H (Testers wanted!)
  • Sunny Island 8.0H (Testers wanted!)

Important

The Sunny Island inverters are rated for 48V. Make sure the battery you intend to use matches the voltage requirement!

Compiling the software for SMA Sunny Island inverters

Make sure that the settings in the "USER_SETTINGS.h" file are correct. The line:

#define SMA_LV_CAN //Enable this line to emulate a "SMA Sunny Island 48V battery" over CAN bus

Needs to be uncommented for the software to emulate the SMA specific LV protocol over CAN. Next step is then to select the battery that you intend to use, for instance if you use the 48V Renault Twizy battery, make sure the following line is uncommented:

#define RENAULT_TWIZY_BATTERY

After setting this up, flash the board!
