Seems MPP dropped a new inverter...a split phase 10KW

I wouldn't hesitate to buy an LV6048 or first gen LV6548.
I'm also keeping an eye on this new unit but won't consider it until it's proven.

Powmr appears to have it for a jacked up price, at least they call it a 10Kw...

Why would it not "last"
I have five MPP inverters, (3x 6048 main system, 1x 2724 mobile, and 1x1012 super mobile) they all work.
My First MPP 6048 was put online in Feb 2021 and has run every day since then.
The second went online 2022, and the third 2023.
Together the 6048's run my business, and most of my home next door. This year with expansion of the PV I will be able to run 100% of my home and business from the system.
They take a charge from my entry level Champion generator without any issues. (I don't own a chargeverter)
I have at times pushed the 6048 inverters to the max.
Five days a week they routinely start and run motors 3hp to 6hp, shop tools including welding equipment and saws.
For low cost inverters, they just work. - down side is they run higher than average idle current. More PV being installed this month!
For the guys with the twin 6548's (original ones with the 250v PV inputs) we never hear of any issues, they say "these run like a tank".
So, I ask, why would the 10k not "last" ?

My voltronic sungold tp6048 is still going strong with zero issues. Powering my 4000 sqft house quite nicely.

Plan on adding more of them.

For how long? years?
My first MPP 6048 is now more than 3 years, 365/24/7 - is this the exception or the norm?

Edit: I am curious about the new MPP 10k (that is what I call it) I have sent MPP a question on the idle current - see what they say.

Mine has been powering my home since around march first of last year. 10 days or so to go to being on for 1 year. Even when I messed up the display on it and they had to send me a new one it kept powering the house even with the display messed up :)

If it wasn't for the forum I'd forget its even out there.

For every one that just works I see two here with blown parts, error codes and problems. Confirmation bias maybe but going from the chatter on this board no one is buying them any longer

Anecdotal evidence at best then,
Did @Will Prowse blow any parts, or have any error codes or problems? IIRC Will ran his pair of MPP 6548's for a long time before his new place.

Will prowse is one person. How many 6500ex posts did we see where the unit failed within a matter of months? Countless

With just the one model or multiple models?
Was the cause anything to do with the waterproof enclosure? (ie heat build up?)

Seemed like the one model from what I remember. I never followed along to see the “why”
Although I’m sure they’ve discovered and adjusted by now (at least one would hope)

I don't like to rely on 'hope'
I like to understand the root problem and what (or if) they did about it.

I have seen a number of posts on the EG 6500ex's
although those are not sold by MPP.
Is the New EG 18kPV built by Luxpower?
Click to expand...
Yeah that's why I didn't single out mpp solar and just said voltronics. Although mpp is not without issues either.


18kpv is luxpower brand but nobody knows who builds it but it's certainly not voltronics
 
I think they are an OEM manufacturer (I’ve always understood that voltronics, SRNE, megarevo, deye, and luxpower (surely others still) were all unique entities with most rebrands based off any number of these)

What is the WP variant mean?
Ok found it online, WP is the weather proof variant

Water proof. More outdoor friendly. Mine are in a three sided enclosure with a roof, but out in the elements with wind and rain. The problem with the WP units were they shipped with bad firmware, which defaulted to 240V OUTPUT LIVE on the GEN INPUT connections( very dangerous). A firmware update fixed it, but made the fans spin at max speed all the time( they were whisper quiet with the original firmware).
They also could not share a generator in parallel mode.

MPP came out with a version 2 of the units with some hardware changes, including new firmware, but those of us who purchased the V1 units in 2021 were just out of luck. Pissed me off.

The software and front panels also suck, and the parameters on mine sometimes change by themselves. The Android app only shows parameters when it wants. The solar power software requires you to register the units, and input your wireless passwords. I assume they talk with a server in Taiwan or China, so security is also a concern.

Other than that, they seem to work OK, and I have them charging my batteries with power from my SMA Sunny Boys during the day. They run my HVAC, saws, pool pumps, water heaters, oven, dryer, lights, and workshop just fine, but i rarely go over 10KW load at one time.

The SMA inverters have been running non-stop since 2008. Damn good hardware in the SMA units, but they are very simple compared to the features in the MPP LVX6048WP units.
