  1. I think it is time to put the record straight. You only have to look at the wires at the back against the wall to realise this was a questionable installation. Fact is, it was originally one Sirius Energy module (3.55kWh) installed using 25mm sq Cable. Another Module was added (Total 7.1kWh) without changing the cable size. A third Module was added to the same 25mm sq cable. You now had potentially 221Amp at 48Volt available. The Setup of the inverters were also incorrect and the Low/High Voltage settings for the Modules were not done correctly. The end result was not pretty. The cables actually got too hot and shorted out. There was no protection installed between the Modules and the inverters. (Can anyone point out the Fuse Holders and Fuses?). This same installation was redone by a qualified and trained installer using exactly the same Modules with proper cabling and proper settings and the client is extremely happy. What is interesting though is that there was a DC Arc but no fire. If this was lead acid, oh boy, it would have been ugly.
