SRNE Split Phase Hybrid Solar lnverter ASF Series 10Kw

Looks as though Y&H is selling a rebadged 10kW split-phase SNRE inverter for $1700: https://www.amazon.com/Inverter-Spl...9Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=

Free shipping, no tax, delivery within 2 days and a 30-day Amazon-backed full-refund window.

Probably worth the (minuscule) premium over buying from China through Alibaba or AliExpress…

As I scan the market, I’m not finding any other 10kW split-phase options (2xHF or otherwise) close to this pricepoint.

MPP Solar has a 2-box split-phase (LVX6048) but each of those is $1400 and wiring up two boxes takes up more space and is more trouble than wiring up only one…

I’m going to track you early owners for a few more months to comfort myself that any launch issues / bugs have been addressed, but if these inverters appear to match the quality of MPP’s LVX6048, I’m likely to follow in your (early adopter) footsteps…

I hear ‘ya.

You probably heard that California’s initial proposal for NEM 3 included a monthly tax for each Watt of solar panels you had on your roof whether they were producing any power or not.

That tax would have amounted to more than half my monthly electrical bills before I installed solar.

I don’t want to give my utility any reason to come out and ‘inspect’ my meter ;).

I can see why people leave that state. Bunch of authoritarian money grabbing fascists in charge by the sound of it.

May you forever fly under the radar dude.

There are a few rebadged versions of this 5+5kW SRNE split-phase inverter available now:

PowerMr: https://www.amazon.com/PowMr-Inverter-AC-240V-Off-Grid-Controller/dp/B0BM9G8WPW

Y&H: https://www.amazon.com/PowMr-Inverter-AC-240V-Off-Grid-Controller/dp/B0BM9G8WPW

Hope we get a few more new owners reporting on their assessment as the back half of the year unfolds…

(and any update from natehawkv8 would be greatly appreciated…)

No news from natehawkv8 - hopefully that means all is well with his inverter :).

I’m curious about how he found SRNE.

I only learned about SRNE because I reviewed an email from Sunpal informing me about the new 10kW split-phase inverter they were offering including UL1741 certification.

When I read the certificate, it stated ‘SRNE’ so I knew they were the manufacturer.

Y&H is already offering their rebadge of this inverter on eBay for $1670 ‘or best offer’ so I think we’re headed toward sale pricing of $1500 delivered…

I am unsure whether the power drawn from the grid, approximately 45-50W, is being wasted or used for the inverter output. At times, I manually switch off the AC input breaker to completely eliminate grid consumption, resulting in 0W usage.

I have not been able to find any spec on idle consumption but there is a ‘Power Saving Mode that switches off the inverter when load is under 50W and inverter is on-grid…

QBear said:
As for the actual utilization of the 40-50W grid consumption by the inverter, I have yet to investigate this matter. I plan to delve into it further tonight.

If you have a few minutes to perform this test, a few interested members are asking about idle consumption and here is a simple test to measure it:

-take inverter off grid (AC input not connected to grid by opening breaker controlling AC input) at night when there is no solar power and the battery is charged.

-turn off all critical loads except an AC load of 50-100W and using a clamp meter, measure both AC output current/power from the inverter as well as DC input current / power into the inverter.

That difference between DC power in and AC power out at such low output levels is dominated by idle consumption but there is also a component of I^2R losses which will grow with increasing output levels.

So for bonus points, if you can make a second similar measurement powering a higher-power load of 500-1000W, we can know how much power is consumed when the inverter is on but not powering any loads as well as how much power is lost to I^2R as output levels increase…

I'm also curious if they're actually stackable. The "/" I'm finding in the spec sheet of the SRNE and the PowMr rebadge is concerning. I have no idea what that's supposed to mean. I have an email in to a supplier to see what they say.

I’d take that to read they will eventually have some capability to synchronize / communicate between multiple inverters, so hopefully eventually but not in this first release.

The fact that there is a RS485 port, a second RS485/CAN port and a USB port should mean it is just a matter of software /firmware…

This is ground control to major @natehawkv8, I hope your circuits aren't shorted, can you give any updates on the ASF48100U200-H?

I assume his inverter is working so we’ll for him that he no longer pays much attention to it…

At least that’s what I hope (but would appreciate an update as well :)).

Please don't use NEC requirements to comment on the internal wiring of manufactured items, it does not apply to manufacturers. Their rules are different. We see this a lot with generators, electricians don't believe alternator ratings because the internal wiring is smaller than they expected. However, manufacturers will use higher temperature rated wiring and take length into account.

Split Phase Residential Storage lnverter 8KW-10KW - SRNE Solar

ASF series All-in-one Solar Charger Inverter Rated Output Power 8,000W/10,000W Rated Output Voltage 120/240Vac Rated Battery Voltage 48Vdc
www.srnesolar.com

So far no problems. I made a quick video:

It was looking for a single all-in-one that was able to do split phase and 10kw or more. I also wanted MPPT that could accept high power arrays. This model was the best fit I could find. Each MPPT in this unit can accept up to 5500 watts of solar and up to 22amps. MPPT voltage range is 125-425 with a max VOC of 500 Vdc.

I wish there was an option to parallel it to a second unit in case I add more arrays, but there is no option for that.

Hi Nate , so now it's about a year later. What do you think of this inverter now ? I was going to get a Midnight Rosie but got hit with an unexpected LARGE tax bill $$$ ...so Rosie went on hold. Then i noticed Midnight DiY series ...which led me to SNRE , which i believe is a rebranded SNRE . What's your thoughts after a year ? My setup is an 100% off grid cabin on very remote land, currently running a Samlex PST-3000 , four AmperTime 12v-200AH at 12v . My consumption is pretty conservative except that i like to run a 3 monitor PC , Ham radio gear during contests and occasionally weld, which my Samlex did run up to about half the welders capacity. Thanks Sir !

We have another member, 420OhmsPA, who just purchased one direct from SRNE through Alibaba for $1380 delivered.

Not sure when his is expected to arrive but that is another datapoint you might want to track.

I don’t know whether it is in this thread or somewhere else, but the primary DIY tech at Midnight Solar has been using / testing this SRNE inverter for over a year now and has been impressed with both capability versus specifications as well as quality.

So unless you have some specific requirement you are concerned about, I believe we’re past the point of worrying this inverter is a piece of garbage and a huge mistake.

Not having tested any of these inverters myself, my sense is that this inverter delivers at least the performance and quality / reliability of any Signature Solar EG4 or MPP Solar offering.

Lack of updates from Nate or any other early owners is much more likely due to the fact that the inverter is performing so well they are paying little / no attention to it and enjoying their lives as opposed to having issues they have not taken the time to post about here on the Forum…

It’s not quite as cheap as the $1380 that 420OhmsPA negotiated directly with SRNE through Alibaba, but here us an AliExpress add for $1421 with shipping: https://www.aliexpress.us/item/3256...p4p_id=202308202247014807714119942333892443_4

Saves the hassle of negotiating through Alibaba if you’ve never done so but you would want to confirm that there are no duty included within ‘taxes’ and that it is just the standard sales taxes you’d pay on any online order…

But confirmation that $1400 is the market price for these 10kW HF 5+5 SRNE inverters (direct from SRNE in China).

SRNE ASF48100U200-H 10Kw.

Slowly making progress. Note to self, go with at least a 6x6 gutter next time. ? What a pita a small size is.
diysolarforum.com diysolarforum.com

Definitely not as advertised based on my readings when I first fired it up but I'm going to kill all loads in the next couple days and clamp it again because my pack isn't dropping anywhere close to what it did with the TP6048 /LVX6048 /EG4 6K overnight(with the same loads). I can't find the spec in the manual but remember a sales rep saying ~70w, I asked again and will share a screenshot of they reply and set them straight if they are wrong (not that it will help).

We, for starters, that inverter is only 5kW (2.5+2.5?) while the 10kW model is 10kW (5+5kW).

I’m unable to download the manual but if you can post a working link here, I’ll have a look…

Ah, from the details below I see this is a single-phase 5kW inverter.

You need two of these to make split-phase (and unclear whether they can do 240VAC / 120VAC split-phase).

At best, one of these is only half of what the single 10kW / 5+5kW split-phase model has is.

That inverter is (the u model anyways) is 5kw single phase, but is parallelable so 2 of them would equal the asf, whereas the asf is not parallelable (the u version).

That is correct (and you’ve answered your own question).

The 5kW model can be paralleled to get more than 10kW of split-phase power while the 10kW / 5+5kW model can not (limited to 5+5 kW maximum).
