Gavin wasn't on a grid connection but rather feeding power from another inverter.Excellent vid Gavin. I'm impressed with the idle consumption. I appreciate that you went over the pluses and minuses.
Sadly it looks like the same megarevo problems that plagued the old units are still there. Namely -it works well as an off-grid inverter but the grid interactive features don't seem to work.
Thanks for putting this out there, this unit remains on my list for my shop system. Good info.Call and chat with Ian maybe. I believe it functions well in that department also. That’s part of what they worked in the last year or so with firmware updates.
My grid options were limited. So testing would have been a bit complicated for time of use and other settings. In the next couple months I may try to work on ways to test options like this easier.
Shouldn't matter so for now I remain skepticalGavin wasn't on a grid connection but rather feeding power from another inverter.
I would not call that a fail for grid interactive features.

I'm not so sure I care for the electrical push in connections. That is a minus for me.
Not a fan of push connections as it seems sooner or later, the spring or some other component of the connector, becomes weak and creates a poor connection. Have a lot of issues at work from loose/failing push connections. Space wise, yeah, I get it.I think considering the space that was probably one of their only options. Once the wires are installed I actually liked the tight form factor. But while you’re wiring it you’re wishing for another 4 inches of wiring compartment height.
I think over time the heat generated weakens the spring, once it gets to a certain point, it compounds.Not a fan of push connections as it seems sooner or later, the spring or some other component of the connector, becomes weak and creates a poor connection.

I have to ask if you had any N-G bond in the breaker panel after the NDX when performing this test?I did try to zero out the 18kpv but the 2 units did not like playing together. It was like an echo between the two units. A very messy wave form. Lights were strobing.
So unfortunately I can’t speak to that.
I have to ask if you had any N-G bond in the breaker panel after the NDX when performing this test?
Did you have a bond in the sub panel?As in did I bond the sub panel myself? Or did I read a G/N bond?
Did you have a bond in the sub panel?
The reason I ask is the both inverters are of common neutral architecture and if there was a bond present in the subpanel at the time power was fed from the 18Kpv, then it ends up a parallel path. These inverters use ground as a zero reference point, any voltage on the ground can cause the light flicker you experienced.
So ... yeah ... the inverters have been sitting at UPS, in the next town over, for the weekend. Been welding up the next pole mount and PaTiEnTLY waiting for the man in brown.
yes but in negative numbers, so I'm wondering if the wires are passing through the sensors in the correct direction. with my clamp meter if I clamp backwards the numbers are negative forwards positive (just by reversing which way the wire goes through the clamp) just wondering if that could be the reason for the misbehavior?It was showing the watts the 18k/grid was using to supply loads.

Ok. Gotcha. I watched Ian's video again where he was pulling from the grid and it showed negative numbers as well so It looks like all is wellIt was showing the watts the 18k/grid was using to supply loads.
