The DP3 is only compatible with the Delta Pro extra battery -- not the other unit nor the Smart Home Panel v1 which is a shame. They have seemed to abandoned the loyal fan base of Delta Pro originally. Also the DP3 is still limiting to 150V (1800 watts) just like the DP --- why is that when the all in one units can get 450-600volts? I think they missed the mark.
Most other portable power units that I know of have only 1 product line that works with their home panels. I don’t know of any other portable power units that accept more than 150v from pv. What units are you referring to?
If in fact there are 2 separate inverters a 120 ans a 240 split phase then allowing both to be on at the same time would effect the 4000 watt output. Most like otger problems arose gaving both on too, so they just turn off the other when the button us pressed.
I own 7 EcoFlow pros, 4 smart batteries and a new delta pro 3 running my well. I have been living off the grid to Summers now with EcoFlow batteries. 36000 watts of solar. Have you tested your previous model Delta pros with your vault meter. Like I said in the first thread I’m getting 55 V on each hot leg and a ground. It should be a ground a neutral with no power to it and 120 bolts on the other hot leg. This is how a 30 amp RV is set up to run. I’m sure you’re well aware of this.
My five Delta pros only put 53 V at each leg of the RV plug, which is incorrect. Why no one has covered this. I don’t understand it should be a ground neutral and 120 V. Delta Pro has not been helpful. Speak English terribly and are very uneducated. You also cannot use Delta Pro as a slave battery. Cannot charge while you’re using them in your drawing a lot of wattage. Solar AC charging while using a lot of water with the battery cut it out. I don’t know why people think this is a good back up system for their house when you have to store them at 30% so don’t ruin them. Internet hype
