Great solution. Thoroughly recommended.

I'm in the UK and I ordered a pre-configured Pi and cables from Solar Assistant in Pretoria. It arrived in a week and took only minutes to install. The user interface is clean and intuitive and is a HUGE improvement over the app provided by my inverter manufacturer. The range of batteries and inverters supported is impressive. Support requests have been addressed in a timely manner. For a TINY fraction of the cost of my solar PV system the usability has been improved immeasurably. Thank you!
