Was wondering if anyone has a EASUNpower inverter, this is a new seller10/08/2017 on ebay. Not sure if I believe the feedback good or bad. they have a few models for the North American market.
most seem to be clones of the MPPsolar inverters
https://www.ebay.com/itm/110V-Solar...Charge-/322836768642?var=&hash=item77337a03b2
easunpower001 (18 ) does seem to have a better feedback than maximumsolar_us (0 ) 3/04, 2011


The only advantage of this one over the MPP solar units seem to be that it is available in 48 volt. price wise the MPP units are a better price. should say supposably available in 48 volt.

hmm they might be the same as voltronic and mppsolar, but it seems Easunpower has the inverters we've been looking for. 48v and capable of 2 in parallel for split phase. I emailed them to find out if their site has the correct info and prices.
 
Inverter newbie here <--

Am I correct in assuming that if I only use 1 inverter (and thus one on one phase) only my 120v small appliances will be able to take advantage of solar and NOT my 240v things (like central AC's, Dryers, Stoves, etc)?
 
Crosscheck that. Because if they say they have split possibillity they either dont know or they arent voltronic based...

This is correct. In the above listed inverter, it will only output on 110-120V, or for US market, 1 hot leg. You would need a second unit to be able to supply power to the other hot leg to get your full 220-240V. And, they would need to be able to be synced. Some inverters can't be synced with each other in this manner. For resistive loads, syncing may not be absolutely req'd, just the device won't heat as efficiently. But any electronics or motors will need to be synced. So, the electric water heater would be fine, the electric stove would be ok, but the dryer would not.

On their web site,EA Sunpower, they don't say whether those units can be connected for synced 240V. They do say you can connect up to 6 in parallel (which would increase your Wattage output, not voltage). When in doubt, call them up
 
If its voltronic based unit they wont be able to sync to split phase. Only 3phase.

Yeah, on their official site (which is hard to navigate; some broken links and misplaced products), it shows that it can do "per phase" on AC output for the "IGrid SS Plus 10KW" model only. So, I would gather that that is split phase operation. Although, they don't show on the web site how that is hooked up to accomplish that.

Yeah, wonder why these aren't listed on their web site!?!? On the datasheet listed towards the bottom, it shows the IGrid TT 10kW as being the split phase. The others aren't shown to be phased.

That's where it gets confusing, at times. One part of the listing says one thing, and another part says something else. Which part do you believe?

However, reading over it again, at the very top of the listing (can't believe I missed this):
MODEL -- IGrid-SS 2KW
Phase -- 1-phase in / 1-phase out

So the 2kW model, listed, is only 1 phase

Addendum:
The IGrid TT 10kW is listed as a 3-Phase unit
 
A split-phase or single-phase three-wire system is a type of single-phase electric power distribution.
perhaps this is the explanation. They need to hire someone that understands us electricity and who can write technical manuals in English.
Just needs to be synced since they are hybrid inverters one inverter would be synced to L1 and the other inverter would be synced to L2.
 
3-Phase inverter will not work on Split-Phase power. Not properly, at least. The only way to get a 240V Single Phase EU inverter to output 120V Split Phase is go through a Transformer with a center tap. And to have a transformer that can handle the loads the inverter can dish out isn't cheap. It'd be better to find an inverter than can do true Split-Phase to begin with.

You can't take the 2 Hots from the inverter and hook it to split phase. It won't work.

Now, if you have the ability to build a transformer with center tap, that's a different story.

Now, if you are referring to the manufacturer hiring someone who understand US electric and what not, they already have that. They just decided to not build a unit that can do split-phase. They have several that can 120V just fine.
And yeah, they need better English as it is the language of Commerce

That was posted by the seller of the unit on eBay. That is not listed on the manufacturers or the distributors web site. I personally would not hook them up that way myself or encourage anyone else to do that. Not until I see documentation from the manufacturer and distributor that they can be hooked up that way.

The manufacturer and distributor both state that the unit can be connected parallel, and mention nothing about that type of connection.

The reason why that is bad, is because if one unit is slightly out of phase with the other, it will being to reek havoc on motors that require 240V (dryers, for example). The two units MUST be in correct phase and Hz and timing to be used properly in that configuration.
They may work like that in Grid-Powered mode. But when the grid goes down, and running off DC power, they could drift.

Daromer (I think it was him) has contacted them several times and I believe he stated that they weren't going to build or support 240V 60Hz split-phase for the US.

Addendum: I wanted to add. If these were cheap units, or ones salvaged or bought from someone else and little or no money was put into them, then I could see someone hooking these up and doing tests to see what they could do to get these to work for US mains. But, being new, I would not recommend it. They are too expensive to test out that way.
 
If it sounds too good it probably doesn't exist in real life :(

Yeah this is the interesting part because nor MPP or voltronic say its possible and I find no reference of it. Of course its just a matter of software to allow it to be "split phase" instead of 3 phase. Have they released it or not?

Who dares to buy them and test and crosscheck it?
 
I emailed easun power and asked if the seller on EBAY and the one on AliExpress are Offical EAsun stores
Hope they are reaally connected to the manufactor and not folks looking to make a fast buck selling products that don't work or are vaporware.

Dunno if this guy is an "official seller" but I did just buy one of these from this exact seller and it appears to work fine.

I am currently running my computer on it as I type this (though on AC bypass right now since the sun went down, but was on solar earlier). Also have my fridge on it, but when I put my 1700w microwave on it I get overload warning (still delivers the power tho).


So would I be correct in assuming that these "off grid" inverters sync with one of your house's 120v bus when you plug it in (depending on which you plug it into)? Otherwise how are they doing the bypass?
