Paul Oosthuizen got a reaction from Jaco De Jongh in Houston we have a problemSo this morning walked into the garage where the inverter setup is and smelled something burning.
Killed the power and discovered the attached cable burn. It is where cable from busbar connects into inverter
Setup
Multiplus II 5000
Smart solar 150/85 with 12 by 280w panels in 4 strings
2 by pylontech us3000b.
Using 35mm cable between battery and busbar, busbar to inverter.
Got mersen 100A DC fuses on both poles of battery
Was drawing around 4000w two 2kw kettle, 2kw geyser, 2000w from battery and 2000w from panels. Installation about 2 months old. Dishwasher was on may have kicked into heating at same time as kettle (still training Mrs but she may have checked power and dishwasher element off). Have got software limiter of 4500w on inverter to limit battery draw.
I have a bad crimp, bad connection to board?
