Bottom line: How might I make the grid tie inverter aware of the power feeding the house thru all 3 phases?
Details. I'm a month into a total DIY effort. I source used panels cheap and put 3KW on the roof. The GTIL sensor is on only one of the 3 legs feeding the house, so it only sees about a third of the house's power consumption at any moment. I'm reasonably competent at electricity but I never noticed that the house gets 3 phase power from the pole. The issue just never came up. I contacted the seller but their tech spt is just a couple script readers that don't understand 3 phase from a hole in the ground.
So here's what I'm thinking. You guys have any additional ideas?
No way the Sun 2000 GTIL is going to talk to 3 sensors. That will never work.
I could just suck it up. The house uses a lot of power. The 3KW of panels, oriented in various directions to get sun thru-out the day, rarely produce enough power that the GTIL backs off because it's producing as much power as it's sensed leg wants. That makes the whole problem kinda small. Yet, every time I do see the GTIL back off a bit because it only senses 1/3rd of the power consumed, it makes me grind my teeth.
I could get 2 more Sun GTILs. They can be found pretty cheap. Seems like a kinda inelegant solution tho.
I could swap out for an inexpensive GTIL that is aware of 3 phase that someone is going to mention in this thread.
