I purchased a EG4 18Kw pv inverter about 7 months ago and it's been in operation for about 6 months now. I'm not the type of person to usually comment publicly on a product or vender, but I believe I have to in this case. In my opinion the EG4 18Kw pv inverter is great. So easy to pickup and set...

High Voltage is nice, lower current, heat, less chance for connection failure. BUT lots of obstacles. Building your own with code changes may not be legal. Inverter availability, probably an obstacle. I'm in the process of completing high voltage hybrid battery installation. Been at it for...

Glad to hear you're taken care of. Also it's good you gave SS positive input. I personally don't think SS deserves any of the negativity that's on the Internet.

Hi SS Jess Thanks for your concern. I know your technical staff are busy , but my problem has been ignored. So I believe my problem now will be addressed and also we can share results to help other forum members. Thanks JJB

Hi Lighthouse Beacan Follow up, I had my defective inverter replaced with a new one for free in a reasonable time frame. In my mind problem may have been caused me. The manual has a startup and shutdown procedure that I did not follow which may have caused DC buss to short out. Hope that helps...

I will be away from home til next week. Will update then

Need help please, probably something I'm doing wrong. Signature Solar stopped communicating with me and I don't know where to go from here. So I've had my EG4 18kw pv inverter functioning for about 9 months. Been happy with it! I am trying to connect a Generact ecogen 6000 kw generator to...

Hi Thanks for taking time to explain and educating me. I now understand how to set inverter parameters to get generator and inverter to work together. Thing is I see now how inverter system works with generator and no way I want to use their system. Future problems is all I see, not being able...

Hi You do have some interesting input. For me input about SolArk educated me, good to know. To answer some of your questions. I am feeding generator directly into generator terminal in inverter. This generator has a little bit of history. At one time before my solar, generator was used only...

Hi Good idea!

Basic problem seems to be software that isn't fully developed. Some things that support this. I received only one CT and the manual shows only one CT being installed. In the US a split phase system is used, with 120 v loads (the neutral) carries unbalanced current making L1 and L2 unequal. With...

Yes we do have the same. I am on grid and have a bypass. It helped. It's not going happen over night. Main thing for me I got a new one. I believe I caused the inverter problem by not following startup and shutdown of inverter per manual.

I would be interested in sharing information on hybrid high voltage inverters. I will be taking down my Megarveo inverters and replacing them. A couple of thoughts are SOLIS S6 generation and new Growatt Hybrid coming out in second quarter. I want to go high voltage 192 nominal battery voltage...

Thanks for sharing this information. It is a little reassuring to see it will operate. Also having someone to now communicate with. One thing, I wonder how Megarveo was given UL certification when they only have one CT for 240 V installation? US standard is 120/240 V split phase.

Hi Filter guy The fault appears on my generator. Thanks also for resource notes. JJB

Thanks for educating me more. Best thing is wait a bit, it's getting better. I'll be back home next week and firmware update will be first on my list.

Am I understanding correctly from your previous posts that you are having problems locating a Megarevo inverter?

The pictures you are viewing is my battery rack and a UPS battery controller Less Batteries. Rack I found on craigslist, battery shelves I fabricated, UPS controller I bought, wire connectors and wire I bought separately. I'm holding back buying batteries until I make a decision on these...

Hi Quattro head Thanks will check that

Interesting, learned a new word genny,

Hi SS Jess Is it possible for your technical staff to also share conversation with Diy forum?

Ok, I was just fishing, thought Megarevo may have taken that model off the market. Not real familiar with GoodWe. Is that what GE uses, or is that a GE inverter?

I have everything ready for battery, but no battery. I've put a significant amount of labor, investment, and thought into this. I am a retired electrician/contractor, I should know everything about code, not so especially with so many changes to NEC PV articles. I involved our state (Mi)...

Sure I can do that.

Signature Solar is marketing a Megarevo 8k 48V copy. You may be interested Will Prouse on YouTube tested it.

Hi My generator noload voltage is 242 volts. My generac Ecogen 6000 also worked fine on an old Schneider system. Yes I do realize a chargeverter would solve my problems, but shouldn't EG4 be addressing this problem? After all we did buy a 18kpv so we could have a all in one system. The old...

My thoughts exactly. My Generac Ecogen 6000 monitors voltage and frequency very closely. It will not change voltage to match inverter. 18kpv has to match my generator or igenerator will fault out

Thought you may be interested in this. GCE on Alibaba has UPS controllers. Some use them for high voltage batteries to make them safe. Has BMS, Main breaker, Fast acting short circuit trip and more. For a fee they will take your protocol and change their protocol to match so your inverter will...

I purchased two Megarveo R12KH1NA inverters from Bluesun solar In June of 2022. I had and still have a lot of problems with these inverters. I'm at the point of pulling these inverters off the wall and starting over with another brand. Either one of these company's (Megarveo or Bluesun solar)...

Yes, a couple of interesting points. High voltage is hard, but a desirable installation when finished. I had all my ducks in a row and my inspector was happy. THEN Megarevo failed me. So here I am, looking for plan two. Getting late, so tomorrow I will share my previous plans and history of this...

Well I've viewed voltage previously with grid voltage on. Inverter will match grid voltage and is usually between 245 - 250 volts. I haven't been able to note voltage when grid is off and generator is running. I'm reluctant to try generator any more til this problem is fixed, back feed may...
