No errors, just no charging provided to the personal batteries nor to the personal roboport. I have 4 plates installed in modular armor in a 2x2 grid giving +90% to the 4x 500w (2kw+90%=3.8kw).
it does not matter which type of pole/substation zone I am in nor is there any change when standing next to steam engines or turbines.

I thought the same first time using this but u will need to do some research and depending on the batteries it will take long. I know it works since i saw consumption in the power overview. (Also with all researched before infinity, i notice it now at night)
