What is the difference between the firmware of a Sako inverter and the firmware of a Voltronic inverter, and how do you know which firmware can work with which model?

There are so many brands with products that look like Voltronic inverters. Some are legitimately rebranded but genuine Voltronic inverters, others are clones using illegal copies of Voltronic firmware, still others use illegal but modified or patched Voltronic firmware. Still others again are Voltronic-like but run their own firmware series, heavily influenced by Voltronic firmware, but not compatible.

Best to post the firmware versions that you have now, and someone like myself may recognise it, or alternatively declare it non-compatible.

Also, please post a photo of the sticker on the side (if any) with the barcode on it. It contains important clues about whether the inverter is a clone or not.

Well, I will send you all the pictures etc. in the morning,

This model vii 6kw twin
