Awesome!

Great and very educational reply, Thanks!

I have heard conflicting statements from a number of sources. I have yet to get a clear answer, just personal preferences with no explanation.

1) Some say... Systems that have Wind Turbines and Solar modules (with blocking diodes) can use the same diversion controller if the diversion controller can handle the max current.

2) Some say... Oh no! You must use separate controllers.

I'm interested to see what this community has to say. It's helpful to explain why you feel the way you do so we all can benefit from this forum.

Thank You.

Thanks for the reply guys!

Thanks Ken.

Thanks for the reply!

Any idea on which inverters are full voltage inverters? I've done a search on altE and haven't come up with one that specifically says "full voltage inverter".

The trace I have has the ability to be hard wired, but it still has the hot neutral.

I guess the best bet is to get an inverter that has a 220 output and wire it code.

Thanks,

Does anyone know the best way to physically verify the AH capacity of flooded batteries?

This would be nice to check if the manufacture AH rating is accurate.

Thanks!

Please excuse my question if it sounds goofy, I am new to wiring ac inverters into isolated sub-panels but have never seen any real discussion on this subject...

As I understand all 110v inverters swing the AC at the ground point 0v on the inverter making 60v per side equaling 120v. I have verified this with a multi-meter and scope. I guess this is why you never attach the neutral to a point on the breaker box where it bonds with ground. Both sides (black and white) are hot.

I have 2 110 output inverters... a dinosaur Trace Model 810 and a modern Ames 1250. Both swing the output voltage 60v+/- hot/neutral from ground equaling 120v.

If a breaker or fuse was not on the neutral line at the box there would be no protection if the 60v neutral side would short to ground it would energize the chassis. Right? (hopefully the inverter would shut down, but...)

Here's would be a real world example:
If there was an inverter connected to a off-grid sub panel (/w neutral isolated from ground) wired as if we were using standard ac (1 breaker on the black wire), lets say the inverter was not turned off and you just flipped off the hot breaker to do some electrical maintenance, wouldn't you get a 60v AC shock on the neutral?

It's confusing to me and why I asked the original question.

Thanks for the reply!

Should an inverter feeding a lone subpanel feed both sides of the buss (as 220 would) then go though 2 breakers to the 110 outlet?

The fact that each side of the inverter has 60v seems that it should be protected at the panel on both legs... Right?
