So Fault 90 pops up on my Mppsolar lv6548. The unit is fully legit and bought on eBay from the only mppolar seller that has %100 feedback with 6860 sold. I understand this is some type of bullet that shows up after 60 days that disables your serial number and it needs to be reflashed with some GitHub python code. What kind of BS is this? What other timebombs or bullets are built into this mppsolar hardware? Some secret fault code that isn't even listed in the manual. Maybe mppsolar detected the Sungold power 6548 unit it is split phased to? again what kind of BS is this? What happens after 6 months or a year another bullet and the hardware goes down again? My power went out for 24 hrs because of this and I had to rewire everything back into my main panel in the middle of the night. I am off solar right now. I wonder how many weeks of back in forth with mppsolar this is going to take. Anyone have any ideas, fault 90 will not clear.,

Sorry to hear about your problem.
Is there anything that we can read that tells us more about this disabling code and why it happens.
 
That code is not in my book either.
To restart, did you turn it off, take away ALL power, PV, Battery and Line(if connected) and wait at least 5 minutes? Use a resistor to recharge the inverters before you close the DC. Check that you have DC to both inverters. Now push both start buttons and reconfirm to have same voltage at both inverters.
One thing you may have working against you is, thou you have two Voltronic family 6548 inverters, however they may have different software editions. That sometimes doesn’t play well within the same rebranded model I hear.

Some good info here: MPP Solar LV2424 Hybrid Inverter Error 90 Fix same vs software...worked fine The only reason why I bought the Sungold was the extended waiting time for the unit I got the Sungold in 3 days while still waiting an additional month for mpp solar.. the units are exactly the same...clearly made in the same factory.fr_13_size880.jpg

The LV6548 is available on Watts247 and has been in stock every time I look. Better pricing, and better customer support. No BS.

The different firmware from different suppliers definitely could be throwing it off.
 
wasn't in stock when I was buying. theses units are all made in the same factory. if u buy a container u can put your name on it also. it's the stupid in fighting between chinese companies that is a big part of the problem. With this thought process you would have to call signature solars version of the 6548 a clone.. sungold worked out a deal with the mfg to also bump pv input in the next version like sig solars. I just dont like that fact it has any type of bullet. I can pair that inverter with a key and a kite if I want to its none of mppsolars business. now maybe in retaliation sungold with send a bullet to their unit in the next version to get even.

Just imagine how Ian must feel. He not only delivers proper service on these Inverters, figures out issues and solves them and then promotes them to the point where the MPP brand is trusted in America and then as a reward he gets thrown under the bus by them putting a flashy paint job on the units and selling them to another distributor.
Absolutely zero loyalty when dealing with these companies.

And then the other distributors giving the LV6548 (and other models) a bad name, simply because the distributor sucks.
 
Google search came up with this. It might be result of a distributor re-flashing firmware.

Error 90 (fault code 90) results from a mismatch between what is in the bootloader and what is in the rest of the firmware. Believe it was designed to catch clones who copied the firmware but not the bootloader.

Also found a YouTube video on how to fix it but it is in Spanish. "code 90 error SOLVED inverter solar mppsolar"

How do you guys feel about MPPsolar having an unlisted fault (90) that disables your machine just because you used it with a different brand same exact unit? Having it work for 2 months (to trick you into thinking it's another problem) and poof power goes out on the hottest day of the year.

you got screwed by your seller, who sold you a "fake" or otherwise not valid machine
full stop
take your complains to him.
There are plenty of warning everywhere to be careful and only purchase from original manufactorer of distri's

They are an established distributor for MPPSolar with over 6064 sold units with 100% Feedback. They were the ones that gave me the info on how to contact MPP solar. So what you are saying the clones are taking out other clones not MPP solar (mfg). Sungold power 6548 is running fine. I wouldn't have this problem if I had 2 sungoldpower units... The problem is the MPP solar lv6548 taking itself out once it detected the Sungold. The lv6548 is legit and the one with the problem. Not sure what you are talking about, lol Full Send. I wasn't taking my complaints to anyone. Is this your forum? Don't tell me to take my complaints anywhere! If reading this thread is causing you to much stress, I would suggest not reading it.solar.JPG

I understand that English may not be your 1st language and you seem to have gotten off track by jumping on a few trigger words which clearly have clouded your ability to understand what is happening here! So let me help you out with some hints. If you had to pick the clone, (not saying it is, in actuality it is another distributor) but let's just say an evil clone. The Sungold 6548 would be the suspect. Once you put both units in split-phase the100% real MPP solar 6548 detects the big bad evil clone (another legit distributor, Sungold who also had the unit modified for higher PV input((like the other big bad evil clone from signature solar) ...detects and then disables itself. I hope that helps you clearly understand what is happening here!

what i understand ...

you wanted a second inverter
you weren't patient, and bought a similar inverter with different specs
you expected them to work together, which they didnt.

now you're pissed at the manufactorer of your first inverter, blaming them for incompatibility with a clone

that sums it up a bit ?

you took a chance, it didnt work out, talk to yourself and next time control you patients
 
and, to stay a bit constructive..

what you try do is upgrade both inverter's firmware and frontpanel's firmware to the same .
ian has released firmware, so i suppose you could ask your seller for it.
take a chance on the sp accepting the mpp firmware

well you are getting there....let me help you out some more. Sungoldpower makes sp6548 (recently had the mfg modify their model to handle pv input 399v (I think they couldn't go to 500v because of the exclusive deal with signature solar) signature solar makes 6.5kW Off-Grid - EG4 6500EX-48 Inverter (upgraded pv 500v) and MPP Solar makes lv6548. All 3 are distributors of this product. if you call the Sungold version a clone you need to call the signature solar a clone also! (neither are clones) MPP Solar warns you about clones of this device (which there are many) but fails to mention that there are other legit distributors out there ! Mpp solar does not have exclusive rights to the inverter! The mppsolar version has the fault90 code (must have had the mfg modify the unit just as sungold and signature solar had the pv input upgraded). The MPP solar version is the only one with this disabling feature
 
Technically they are all clones of the Voltronic MAX inverter. So yes the EG4 is a clone.
