I'm looking for an inverter that will combine AC input and solar/battery to reduce my electric bill without going to a grid tied inverter. After doing some research I found some post here about an EG4-6000EX back-feeding the grid, and a video of someone claiming their MPP LVX6048WP is back-feeding the grid with 250 watts when it was set to off-grid mode. I also read here that the LVX6048WP had an issue where the generator input was energized which is should not be. I'm trying to find a UL listed inverter for no more than $1500 maybe it's not possible. I can't afford to get into trouble with my utility back-feeding. I don't even know how you can test for that before you plug it in. I suppose have to look for voltage on the grid input side before connecting it while it's in off-grid mode.
Does this seem to be a problem with some hybrid inverters just by design is the grid input directly connected to the inverter output combining the two? When you set a hybrid to off grid only it's really just using internal CT clamps to keep it from back-feeding.
Video I found on YT poster says LVX6048WP is back-feeding his meter is going backwards with the inverter set to off-grid.
