Install and Operation of the SUNGOLD 10KW 48V SPLIT PHASE SOLAR INVERTER

[mciholas]

Looks like Sungold has a new inverter listed:

They seem to have two units that are 10 KW split phase 48 VDC hybrid inverters.

The unit above is SG10KHB-48 and priced at $2400.

10KW Hybrid Inverter 48V Split Phase

Highlight: ★ Hybrid Split Phase Inverter: 10KW Pure sine Wave Inverter 48V DC to AC 120V/240V, built in 4 MPPT Max 500VDC input each total Max 13000W PV input. ★ Multiple Charging Modes: Off Grid Solar Inverter have 4 charging modes: Only Solar, Mains First, Solar First and Mains & Solar hybrid...

Another unit is SPH10K48SP and priced at $1670.

10KW 48V Split Phase Solar Inverter

Highlight: ★ All in one unit: 10KW Pure Sine Wave Solar Inverter Combined with Max 200A battery charging, 2 MPPT Solar controller inbuilt, Max.Voltage of Open Circuit : 500VDC, Split phase (120V/240V) or Single phase (120v) output. Wifi module is included, which allows the user to view the...

The price difference seems large for what appear to be minor differences in specs.

SG has 4 MPPT and 15 KW PV, SPH has 2 MPPT and 11 KW.

Other than that, I can't really see anything significantly different. What am I missing?

The SG unit says cooling is convection, but it clearly has fans depicted in the user manual. UL 1741 isn't listed either.

Is this a Deye 10k rebrand? @42OhmsPA So this is a poor man’s SolArk basically?

I believe that's a rebranded megarevo based off a post I saw from @G00SE .
I'd stay away from it based on past megacrappo feedback here.

Yea. I posted it in an old thread of yours about senergy. I really thought it was that one
Then I downloaded the manual and compared with Senergy, mpp, and megarevo and it’s definitely the megarevo.
So they went that route and powmr went the mpp route. I guess we will see how it pans out

Imo the SRNE rebrand (the cheaper one) is still the benchmark. It has ONE shortcoming, but I’d rather 2 sub panels than equipment that doesn’t function but is stackable.
They (Megarevo and mpp) probably stack nicely in the trash too.

I love this forum! Thank you guys!!!

Thanks for looking into this @G00SE that makes sense. I know a lot of the guys in Europe and Africa love these Deye 10k, but they’re hard to get into the USA.
It does look also like a Megarevo

I’m not sure what factories are spitting these out. I’ve watched some Deye main board replacement videos on YouTube and I know the boards are harder to get down into and they usually have a heat sink on the backs of the power boards on the low sides. I know I’ve seen alot of posts of guys who love this build design, but I also remember the Megarevo drama so… something to watch I guess.

My SG 10k has been running wonderfully I can’t complain, do wish I could parallel another one tho

There’s a couple of people in here that seem to flip the deye stuff from time to time.
You can find the 12k version (9k output) for around 2500 on eBay.
Seems like a fair deal to be honest if one is interested in that route.

100% my sentiment!

2nd best choice is a second unit on its own battery bank with full communications, right?

Probably the same as the new inverter Watts247 is selling.

Maybe the issues are fixed but I'm not into experimentation when it comes to inverters..........

I think SRNE has April release for stacked 10Kw units. That could be a huge game changer.

I think the watts247 is a different oem, I really like they have been putting them through the paces before releasing them into the wild...
I agree they should work out of the box with no firmware updates, remote logins, support Solar Assistant, etc.

Yeah I’m in a few groups with alot if signature Solar fan boys and they are constantly wrestling with firmware

Just got my February Xcel bill.... just about half of last year... temp was on average just a bit more so that helped, but saved 50% .. excellent...

This bill $97.... last year $183
Electric this year $25 last year $83
Gas this year $73 Last year $101

Yes! This thing is working.

Damn....just had a #12 comm error....third or fourth time since this thing came up... no idea what causes it (or if it's preventable) and only way it seems to clear is by completely restarting the inverter.... i.e. AC off, PV disconnected, Battery disconnected, inverter off --- then power back up... battery....AC input...Solar... Seems fine now though... Arrrgh.. I guess I shouldn't complain... it did keep running even with the error...I came home to find it erroring....not sure how long it was like that... I was gone about an hour or so... had to do the shutdown and restart...and then had to reset the clock on my Microwave.

 

[marionw]

Can you fire up the iPower software and look at the "History" for the inverter?

Maybe I can try in a bit. I didn't think/know there was a history... Log...

Th easiest is the Inverter USB C connection to your computer although the Wifi RS485 connection will also work

Yeah I've seen that ..but doesn't seem very useful other than time...

 

[Kenny_]

No go....this software is so fuckin' flakey can't get it to connect properly or if it did gawd knows... no history to be seen...

I really have no stomach for this so we'll just let it sit.

Thanks anyway @marionw !

I periodically see “Master-slave chip SPI communication failure” but it always clears itself. I had 1 time it didn’t and I rebooted system. I feel like it happens more when you’ve got a lot of demand on a single leg of your output and not a lot of draw on your other L2 leg. Make sure L1s not getting a bigger work out. I moved more over to my L2 to balance my surging and it only happens maybe once a month now if even that, never requires reboot usually blinks fault then instantly clears, maybe try shuffling some breakers if you’re concerned

 

[CaliSunHarvester]

when you’ve got a lot of demand on a single leg of your output

How much imbalance is acceptable by general opinion? E.g. occasionally 5A vs 7A is ok, but 5A vs 30A is not?
