Noobie, have you taken any monitoring data while you were testing solar? If so, please share the data. Two solar controllers failing at the same site is extremely rare. Typically it points to some problem at the site.

This is a new setting to avoid floating neutral. Basically there is an addon accessory called grounding box that would be connected to dry contact of the inverter and it would avoid the floating neutral problem. You should not enable this option if you do not have grounding box connected to the system.

@Jaco de Jongh Do you mean using SolarPower, you are not able to record data? or are you talking about another software?

This model is like Infini but some differences exist. Infini model can work with or without batteries. In this model, batteries are compulsory just like Axpert inverters. In this model, you can connect up to 6 inverters in parallel. So effectively you can expand 4kW model to 24kW system. Jaco, what is the maximum load you have given to this inverter. Any other issues you faced apart from tripping with prepaid meter?

Great installation Mike! Nice to know that you can now parallel this model too.

I don't think InfiniSolar 5kW Plus model can be connected in parallel. The manual clearly says the following: "This inverter is not allowed to operate in parallel. Please do NOT parallel connect more than one unit in AC output connector. Otherwise, it will damage this inverter." The three phase InfiniSolar 10kW can be connected in parallel but that too only up to three inverters.
