Good to hear, questions are always welcome, just trying to offer other solutions.
My understanding is the bare transformer is the same as the one in the box with breakers etc.
I think the diagram is showing the wire nut to the L2 live. The caption referencing neutral is just showing 120v from L2 to neutral, not saying to connect L2 to neutral. If the second diagram added a wire nut to L1, it would be essentially the same as the first?
But why not wire that heater to 240V and spare a LOT of trouble? That heater is a huge imbalance and I'm surprised the inverter even tolerates it ...grainger has several 240V, 750 & 1,000 w elements, and then you could use a fairly smallish (lower losses) transformer,by
shifting the big 120v loads, to 240V. Maybe the microwave & blow
dryer would need a larger transformer to support them but how many hours
do they actually run, and is a $500 transformer worth $20 of
I'd send that element back to Grainger, it should have a +10 year lifetime

ewb, In XW inverter (NA) will not have this balance issue with most home loads because it is a large enough inverter/charger.The same with a 4kw radian from outback and its 8kw version.Think about it, most homes have a 100 to 200 amp service and you are either powering a 30A inverter/charger or a 60A.Which one will have issues?This is not a new problem because in the old days it was pretty common knowledge. I think it is great that folks have got this too work reasonably but, what a pain. It also looks somewhat unsafe to have all of these components laying there. It should be all in one box, in my opinion. A home insurance inspection would have issues with a complicated home power system. I have seen them fail for insurance.If I was not so busy right now before winter I would add this dilemma to the FAQ section in the forum here. It might help someone make the best decision for their situation.
