Hi Deon I am located in Honeydew Johannesburg...I'm not sure if you are familiar with the Solar MD range of batteries. They work in my opinion really well across most inverter/ solar platforms. I have my system hooked up to an axpert & together with the logger can monitor exactly what I yield etc.
Like I mentioned before, I am only selling the unit due to raising funds for another project. Covid has made the world a crazy place & hence one needs to advance some long awaited plans that were previously on the back burner.
