Hi Sungold,
I'm building a home, want to add your hybrid inverter for our 5 kW solar array. But we are not sure if your inverter complies with utility regulations? Is this inverter UL listed? Does this inverter run with solar/grid in parallel so that when there is not enough sun, it uses additional energy from the grid? Or does it just switch to grid? That is - say I need 4 kW, and there is 3000W coming in from my solar panels. Would the extra 1 kW come from the grid with 3 from the solar - or does it switch fully to grid so that 4 kW are coming from the grid? We need an inverter that does not switch to grid, but only tops off necessary power by using the grid.
We would like to get:

Would this meet our needs? Or do you have other inverters that could work for us?
Thanks, Marcin

Hi Marcin,
Thank you for your inquiry.
Sorry that this inverter is not UL listed. But if you do not need to use the grid feedback function, the inverter does not need to be UL listed. For 6000w 48v hybrid inverter, it has two working modes as the picture shown. The inverter can run with solar/grid in parallel. If you need 4kw, and there is 3000W coming in from your solar panels, the extra 1kw will come from the grid.
Or you can consider our 6500w 48v solar inverter, which is UL standard, but its AC input and AC output is 120v.
Here is the link and you can have a look.
