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

Thank you for the info so, sorry you wasted time and money to let the rest of us know to beware, I appreciate bad reviews way more than the good ones. Signature solar will NEVER get a dime from me sir, we need to starve out these companies that won't deliver on the promises they sell. You might want to call your credit card issuing bank when you have problems and see about disputing the charge, you will have to return the junk but in some situations you won't if the merchant won't respond. I use to process charge backs for a living, these people hate selling to me because I dispute the charge right away when I get shafted with junk, chase and citi have both been good at getting the results I deserved. I use to work for bank of america and I would never have any account with them, never, they hire felons in their call centers, I'd never trust the 3rd parties they hire to sub out their call center work, I worked with all kinds of people no one would trust with a pencil but BOA trusted them with your personal info and bank info. As far as that transformer goes I would just build my own for a few bucks, forget paying $300ish, there is no serious tech in there most anyone could learn to build their own. Im working on my own DC to AC system but I'm doing hydro generators not solar, but pretty much the same game just wet.

These are high frequency inverters which are known for problems and short lifespans. Low frequency is what you want. I agree about Chinese making junk... but I also see that these look to be outside., which is crazy. These are clearly only indoor rated, probably the reason they are only lasting 8 months.

have you try low frequency inverters? I read that they last longer than the HF ones

Who among these distributors has come the closest to meeting your customer and technical support expectations? Or have Chinese vendors all failed? Fact: tech support services cost. You can buy good, cheap, or fast. But only two at a time.

Can anybody tell me of an electronics shop that can fix hybrid inverters like the PowMr 10.2?

5 minutes in... uh - I was looking at purchasing (2) eg4 mppt-48v100 charge controllers...from signature solar....hmmm...

How many panels/watts production do you have in your solar array? You said you have never reached 5,000 watts, correct? What make of panel and wattage are you operating under? I only ask because we are putting together an off grid system (48volt) with 96kw battery bank... if I need more panels to have the charge controllers do their job - I would like to know now.

I was going to call Signature Solar to make a purchase tomorrow. Thank you for your information .

Sure they don't always make the best but they sure make it affordable and reliable good enough. Don't believe me go look at the Victron which is Dutch made and see what that will cost you. Less feature and way more money for certain. Cheap enough so why NOT just buy an extra one for back up. Most people don't know this that the always failed part of any electronic device (NOT MACHINE AS SAID HERE) is the high power and heat generated components. Well for all inverters, charge controllers always the power MOSFET. They are so cheap and easy to diagnose and replace if you incline to fix it. Now how do you think i know that???????? Please don't bash the Chinese without them would solar energy be more widely available for the rest of us. They commercialize the lithium phosphate battery which is fantastic affordable for home solar energy storage that lasts for decade and of course they make numerous brands of inverter, charge controller, solar panels. The West industrialized with dirty dinosaur fuel NOW the East particularly China has industrialized with clean sustainable energy from the sun with many discoveries and inventions that came from the West. Both are important but more importantly to commercialize it to be usable and that is exactly what China has accompished. Many people complains about Made in China when they can't afford the more expensive one from other countries. To me affordability, reasonable reliablity are good enough for solar use. They are cheap enough just to buy an extra one for back up. Most definitely i will not give Victron my money as i do not like their high price and less feature. Your money you spend how you please. This is my perspective and experience as i am no newbie in this. I had and have been doing solar for 6 years and I always build my own from battery to the whole system. There is not a day in any of our life that we don't use electricity so it is worthwhile to learn and to take up a fun and rewarding hobby as solar energy and storage hobby. With EV coming up it is even more important as we can use the solar power to charge the vehicle. For those that want to go solar this is my take. Go for the 220V 5kw with stackable feature. Use the auto transformer for 110V stuffs. More inveter, solar panel, battery can be added later if more power is needed. They are so easy to add on and most definitely cheaper than any other way. You don't believe me until you start doing and using it i now that. You think i am doing solar for 6 years and i don't know what i am talking about? Especially when i build my own battery and install everything myself from solar panel to charge controller and inverter. Go for it people. solar is the way to go and the future. BTW I am off grid 100% and will never do grid tie as there is NO reason to. I do not have an electric bill EVER!!!!!!!

HOWdy B-Y, ... Thanks COOP ...

Same problem with Growatt 3000w. New had issues. It's dead. Working on 2 months and no replacement board yet?

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.

get a mic mate

The split phase models are better models to choose. 220-230 throughput from a transformer causes a unbalance in the inverter output

Some texan hate rant towards china, and nothing else.

Thanks for sharing. I am planning to get the PowMR, do you have any update about it yet?

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.

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

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.

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

Iphones are made in china 😂

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.

Schneider inverter the best, no problems.

Sadly almost all solar related products are made in China one way or another, the only difference between US brands and Chinese Brands is QC procedure. Japan, S Korea, Taiwan ,China are all on the same track. In 5-10 years you will repeat same old stories about things made in India.

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....

Verry noisey video why??

Hi I started using the new PowerMr 5.5KW. Now it has been around 6 months. The issue I am facing is with the dust. I came up with a simple solution and made a video to share. hope you and the other members will enjoy this kzfaq.info/get/bejne/atlxi5mIqpamkY0.html

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

Cheers

Outback inverters are made in China and then rebranded in OZ/US like 95% of all US and EU-claimed Inverters SCC, Schneider Electric are UK/US but 90% of their own bulk parts are in fact made in China now. Also, PowMr is the owner of Growwatt. Victron is based in the Netherlands/UK where they assembled it, BUT most of the internals are still made in China, but you get EU/UK quality control, so much western electrical stuff that's claimed to be built in the west is only assembled there now, but you are really looking for is electricals like Mossfets, Caps type internals that are made in South Korea & Japan and sometimes US/EU/UK. There are zero electrical devices made anywhere in the world without China parts inside of them now.

I would not parallel the AC outputs of those two inverters. They would probably not be in phase.

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

Talk about what happened to the inverters

I’ve had a different experience entirely. I have 5 Growatt 5kES working in parallel without issue. Just to speak to the downgrading of Chinese manufacturing. It’s much better now than it has been because of experience. A huge portion of the Chinese work in manufacturing and have done so for most of their lives. Like you said everything is made there. They know what they’re doing. Respectfully.🎉

Similar experience with S/S. No one knew anything and call not returned.

Signature Solar is a piece of work when getting your money Back.

I rather American solar equipment

Awesome video really helped would love to see any updates you have!

E

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.

Greetings , I algo have a 240 volt inverter , you mentioned a transformer to step down for US household use. Do you have a squematic, for your set up and does it require a breaker?

Combiner box is unnecessary

Back the 1st string down y 50v will help

Why not run the 2nd string in parallel w/ 15a in-line fuses?

sungold are nice lvl6548

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

Sure makes me feel better of how it's going for me over here in Texas . Kinda patchy sun . . . T/C/E

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

Thank you for letting us know that GrowWat supprt is not good. I will make sure to calll them up and test their service before I buy anything from them.
