Got the new inverter on Monday and have been testing it extensively. I am running directly into my house using a manual lock out switch. Both phases are being used. Here are some testing results and other notes thus far.
The updated inverter uses a larger Torroid. Even larger than the first one that was sent to me. I attached a picture on the label on the transformer. It is nearly 6 inches tall and has a diameter of 8.5 inches. It is about 20 pounds heavier than the previous transformer. So Power Jack did beef up the single transformer even further
Based on this graph the inverter actually stay cool up until 5K which is where I stopped. I plan to go further when I install larger wire running from the inverter to the main breaker panel.
The next graph shows voltage per phase. They are pretty much equal but what is impressive to me is the fact that the voltage stays near 115 the entire run whereas before it would drop well below 110. I had complained about the low voltage even under no load.
Based on the testing so far this inverter is turning out to be a beast. It had no issue starting any appliance I had around the house. I did not start my central air or my dryer. I want to beef up the wiring running to the panel before then.
Realistically, unless you have a huge battery bank or a very large solar/wind array you will not be driving this inverter to 50 percent on a regular basis. Short stints of 50 percent will happen when certain items around the home startup such as refrigerators or window air conditioners. I will of course test it to my limits but it is showing great potential as being an out of the box whole house inverter.
