  • Sun 2000 GTIL and 3 phase power.

    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...
  • Sun 2KW GTIL. Why would it back off power production?

    Bottom line. My device will produce 2-3x as much power, albeit briefly, if I unplug it from the house for a moment, and then plug it back in. Getting too hot? Device itself is goofed? Scenario. Bright sunny day and 3KW of panels pointed in various directions. The GTIL is producing only half the...
  • Sun 2KW GTIL 110 vs. 220VAC

    The device is available in these two voltages. Does anyone have the 110VAC version and actually plugged it into 110VAC? I ordered the 110VAC version. It didn't work at first, but I read that I needed to cut the plug it came with and connect a different plug so it would connect to 220VAC. That...
  • Charge controller charging/sensing duty cycle: Charge all the time?

    https://diysolarforum.com/threads/how-control-isunergy-controller-batt-charge-state-sensing-time.41180/#post-520916 Talk to me pls about charger behavior. My charge controller spends a lot of time not charging, even tho panel voltage is high. My guess is that it's sensing batt V. This strikes...
  • How control iSunergy controller batt charge state sensing time?

    My iSunergy controller is supporting 16s LiFePO4 with a nice BMS. The controller spends a lot of time "not charging," call it maybe 1/3rd of the time. So it will charge for maybe 10min, then not charge for 5, even tho the panels voltage is plenty high enough. My guess is that the charge...
