Hi guys, I am on my second unit of Masterpower inverters UM v4. The first one I had was a 5.6 kW Version and I exchanged it for the 3.6 kW version hence I thought the bigger one had an error. But it seems this is a system flaw, hence my second has the same error. I am using this system off-grid with AC IN - PV IN - No Battery (still checking which one to get) - AC Out. Now the issue is that all works fine as it should but the PV INput doesn't show any AMP for the PV array and only volts, therefore also no watt. The same for the AC output. No AMP is showing but volt and every attached load seem to work just fine. I bought now two separate current measurement devices, which should measure AC IN and AC Out so I can subtract AC In from the AC Out number and should know how much KW/h the PV did. however, i found this odd that both units have the same no-show for the AMPS. I wonder if this might have something to do with the not connected battery? I also saw in the box of the inverter this extra DC fuse (blade) and wondered what this is for hence nothing is written in the manual.
I hope someone can help me out here. Would be really appreciated.
