Wish I seen your video before I bought growatt. My growatt never worked how it was supposed to out the box. I have PowMr and connected it and it immediately worked no issues

[@bobcole3852]

Sorry you've had troubles but thanks for sharing. Please give an update!

[@sergtod1352]

Of course, it's not going to work as expected. With only 3 panels each rated at 50 V, you won't reach the required 120-450 V MPPT voltage range. Under load, your voltage will drop to 100 V or even lower depending on the sunlight conditions outside. It's important to note that the type of battery you're using isn't the issue here. To achieve the necessary voltage, you should consider adding more solar panels to your setup and ensure that your PV voltage meets the minimum requirements. In your case, it might be beneficial to consult with someone who understands the specific requirements for proper functionality.

Thanks for the comment, however there are 2 sets of panels, each having 9 panels. Working to maximize the upto 500 volt maximum input from the Growatt.

@@byronyoung6759 If the voltage falls below 120 V or exceeds 450 V in a solar energy system using a Growatt MPPT inverter, it can lead to various issues, including reduced efficiency, inverter shutdown, and potential damage to the equipment. Here's a more detailed explanation of what can happen in these situations: Voltage Below 120 V: Inverter Shutdown: The Growatt MPPT inverter may not operate or generate AC power if the input voltage from the solar panels falls below the minimum specified range, which is 120 V in this case. In this scenario, the inverter's internal protections may prevent it from starting or functioning, as it's unable to operate within its designated parameters. Reduced Energy Production: Even if the inverter operates at lower voltages, it may not be able to efficiently convert the available solar energy into AC power. This results in reduced energy production and lower system efficiency, as the inverter may not operate at its optimal power point. Voltage Above 450 V: Inverter Shutdown or Damage: If the input voltage exceeds the maximum specified range, which is 450 V, the inverter may shut down automatically to protect itself from potential damage. This is a built-in safety feature to prevent overvoltage-related problems. Reduced Efficiency: Operating the inverter at higher voltages than its rating can reduce its efficiency. It may not be able to perform maximum power point tracking effectively, leading to energy loss and potential overheating. Inverter Damage: In extreme cases, if the overvoltage situation persists, it can lead to damage to the inverter's internal components, potentially rendering it inoperable. Repairs or replacements may be necessary, incurring additional costs. In both cases, it's crucial to maintain the voltage within the specified range (120-450 V in your case) to ensure the proper and safe operation of your solar energy system. Solar panels and other system components should be configured and designed to keep the voltage within this range. If the voltage goes outside these limits, it can result in reduced energy production, inefficient operation, inverter shutdown, or damage, all of which can impact the overall performance and longevity of your solar energy system. To prevent such issues, work with a qualified solar installer or electrician who can ensure that your system is correctly configured and that all components are operating within their specified voltage and current ratings.

My 48V inverter from Povmr burned out after 2 weeks of use. The fire did not happen only because it was the New Year holidays and I was at home. At the same time, solar cells were not connected to it, and the load was only 600 watts from the nominal value. Both the manufacturer and the seller are trying in every possible way to avoid liability and warranty repairs by ignoring requests. Now the reason is gradually becoming clear - devices under this brand seem to only look like Voltronic. The low price is apparently a consequence of the cheap element base and the reason for the lack of after-sales support.

[@geraldhenrickson7472]

What are you omitting here? Have you talked to POWmr? What exactly did they say? Have they requested you send the failed unit to them? Are you saying theydenied warranty? What is the current state of affairs?

What would be a good brand transformer to go with a 5500watt mr power

[@GregoryTarver-es8pr]

I have the same problem with growatt been using Powmr no problems

[@randylenart9674]

Ya need to look into a genatry solar 6k low frequency inverter designed in the states and made in china but repairable in michigan and there coming out with a 12k soon

[@loungelizard836]

PowMr also has a stackable version, it's about 350 usd less than the GroWatt. I'm looking at buying one, but haven't compared for quality yet. Watched David Poz's video on GroWatt, it looks pretty good but haven't seen any comparison. The 150V may not be enough to trigger MPPT on the GroWatt.

[@piterex7]

I guess sir you have the order version of growatt 3000 ?! So many peoper have the growatt se3500 or 5000 ans newer have problem ! Did you set up the right set for lit batter coś winy work with prąd Acid if not Settings sfllected !and in europ we us 240v and one more think IPhone is assembly in China doesn’t mean is cheap and crap

[@SiriusSolar]

So did the new inverter work well? It's been 5 months since you posted this video.

[@byronyoung6759]

New update, check out if it worked

[@williamkn621]

I tried to watch the whole video hoping to see covers off, connections or some technical items but all I say was talk complaining about them. I left disappointed with your video and not really thinking I'd watch another....

I have the same problem with growatt been useing Powmr useing no prbloms

[@springer-qb4dv]

Yes used solar panels are great deal. Just because it's 20 years old, doesn't mean they are no good. Old panels can keep running for another 20 years easily with good care.

[@Xxxcappie23]

Can you explain the transformer comment a little more? If you stay in Europe you need a transformer with this inverter ?

[@byronyoung6759]

The inverter is producing 240 volts. So here in the US we use the transformer to step it down to 110 volts

[@ilingwang1168]

Since u never mention the model number of the Growatt u are having problems with. I looked at the Growatt site to see what would match the one u have physically and the technical specs u described in this video. It looks to me that u purchased a SPF 5000 US. That model shows an AC output of 230VAC. That is an European voltage, not for the U.S. market.

[@timothymaggenti717]

I am so impressed that you deduced all of this a year ago? You are so right and the writing is on the wall right now. Rev 17 says they will all be of one mind, a one-world government. The 10 heads are the current leaders of this WEF etc.

[@odeywilliams7596]

You are sopose to plug in the batteries b4 you plug in the solar panels thats why it blew the inverter

[@byronyoung6759]

Well yes and no, the batteries need to have power before solar. So 5e order goes batteries, Solar, then grid power. That’s not what caused the failure of the inverter, but thank you for your input.

[@TheRenePirovano]

You use a transformer to get 110 volt, you're inverter sees a inductive load on its output. That's probably the problem of all your inverters. When your inverter output drops in voltage the transformer reacts by forcing a off fase higher voltage on your output. Normal grid doesn't behave like that. Buy an 110v inverter!!

can you reset audio?

You are dabbling in 220v. Perhaps that should be in the title.

[@sistemasrenovables]

Actually they are both made by the same Chinese factory. Voltronics the difference is on outputs connections and model not quality.

[@williamkn621]

Voltrinics or SRNE?

[@loungelizard836]

A coronal mass ejection (CME) will produce far more damage to grid and networks than any nuclear weapon! Just about anything with microchips will fry, so maybe a low-tech inverter as a backup would be useful!

GROWATT IS JUNK i got one that lasted 3 months. i have 2 MPP thats been working nearly 4 years

[@GreekSIMRACING]

So this dude plugged 3 panels with open SoC 50v which are on theory 150v DC and he expects to have a proper functioning unit 😂,ok i think 🤔 he needs at least 350v open circuit from 7 panels with actual 270v to get 230V for EU.

[@byronyoung6759]

Thank you for your comment, there are a total of 14 panel’s connected. 7 and 7, with a verity of 400 watt and 340 watt. Each run has about 1900 watts and 500 volts.

Hi Bryon, I feel your pain on growatt inverters. They're just an okay brand, not superb. Their distributors are ok to work with BUT growatt people are terrible, hard to work with, no service mind, and nothing I can do. I. am stop buying growatt products and buying others.
