Connecting two EG4 3000EHV and running 120v only?

[DustyDesertDweller]

Hi, I have a couple questions. Someone near me is selling two 3000EHV-48 for a total of $1k and I'm interested in using them to power an off grid property. I'd like the option of powering two separate mini splits, and two fridges at the same time. I figure a 6000w inverter should do the trick but will two 3000EHV's connected together give me 6000w of inverter power? Ive read the EG4 6000XP is unable to do 6000w of 120v so it makes me curious if two 3000EHV's suffer the same flaw. I'm also curious if I can set up the two 3000EHV's to operate in 120v only and not split phase as I have no use for 240v. If so I wonder if my 120v inverter generator would be able to charge my batteries via the two 3000EHV's. I have read recently that a 120v inverter generator can only charge batteries via the 3000EHV if it is not split phase but I'm unsure if it is possible to get 6000w of 120v out of a pair of them without setting them up split phase/240v. Any help would be appreciated. Thanks

Yes. 2X give you 6000W @ 120V in one phase.

The 6000XP is a split phase inverter providing 6000W @ 240V and up to 3000W on each 120V leg. So you can get 6000W of 120V power, but you have to balance it between the legs.

Generator should work fine. Note that these are sensitive to generator power quality. They generally respond well to quality grid power or inverter generators that output quality power. Standard generators are often rejected by them.

Perfect, thank you!
