I only have two taiwan type inverters; Mpp-lv5048 and Eco-Worthy 3500 watt. Both are three-in-one types. Disconnecting AC utility input eliminates all flicker. Amazing!
I mean what the hell ! Monitoring the inverter sine wave output on my oscillascope NOW looks great. One of my most flickering led lamps (from the 99 cent store) has no flicker at all NOW.
There seems to be a design flaw (taiwan 3in one systems ?) with the AC Powered 48 volt DC chargers. My mpp-lv5048 in the night time hours after i've switched to utility priority AC output And charger priority source switches to utility-charging. My mpp-lv5048 is pulling and additional load of 250 to 350 watts (battery fullly charged) When in should be pulling an additional 50 watts (battery full charged). Watchpower monitor pc program shows apparent and real power output from both L1 and L2 branches. With the AC charging enabled. The additional 250-350 watts loss is showing up in the real and apparent output readings. L1 and L2 output differences can be seen. And there is a difference of about 250-350watts. With the 48volt charger disabled (AC input breaker switched off or disabled via softwewe settings (charger out priorty = "solar only" )) . Power apparent and real power L1 and L2 readings are nearly equal .
The Eco-Worthy 3500watt (looks exactly like RENOLGY 3500 Watt except it is yellow) is a new one I bought on ebay and just fired up earlier this week some of my findings my be a little premature. The inverter in night time mode AC 48 volt DC charger running batteries fully charged is pulling an additional 100 to 200 watts when it should be pulling only 50 watts (battery fully charged). When 48 volt charger is on there is massive flicker on all house lighting. Sign wave output very bad. Sign wave output with 48 volt charger disabled = sign wave is excellant (none better).
