I have a Sun Inverter 24 250VA 230V. It works all as expected. I have connected it through a Cerbo-S (overkill I know) but I specifically want to monitor performance. The problem is the VRM seems to be incorrect. It shows AC Input which is meaningless as the Sun Inverter has no AC Input. It doesn't show PV data ie voltage/yield which seems critical.
Any clues or is this product not designed to work with the VRM?
