Blown up Deye inverter and my Chinese customer service experiences compared to the Europeans

We finally had an inverter fail. The steps the factory took and the service I got from them

[@williamjohnston3770]

I want to commend you on your videos. I'm a licensed Solar Contractor and have worked in the industry for over 10 years. I've installed systems from 2kw to over 1MW of almost every major brand through out the US and the Caribbean. I've watched a lot of solar videos on KZbin and I've truly enjoyed listening to you. I pray for your prosperity and continued success. Keep up the good work.

[@drsolar]

Merry Christmas and a happy new year. When I grow up I hope to do what you have done over the years. Thank you for the prayer and kind words. They inspire me to continue. Remain blessed and extend my love to your family

I was going to advice you to increase your PV array size but I'm glad you mentioned it. You're doing great Dr Solar.

[@drsolar]

Hello Bukola, thanks for watching and commenting. I am at 5 kwp and will be adding a PV inverter and more panels later. Thank you for your kind comments. Merry Christmas to you and your family

About to install a 12kW system on my home with a Deye inverter. I don't know anything about the various inverter brands and wanted to hear some reviews. This video was perfect. So helpful and useful. Thank you so much for sharing this info!!

[@drsolar]

Thank you so much. This means a lot. Good luck with your installation

[@saif080]

@@andred3199 Well first off I am not a native English speaker myself. English is my third language and still it is my only means to communicate with a person outside my country so if a person speaks clear english, it is a lot easier for me to understand them. The maker of this video has highlighted the features of the inverter and what he says, shows that he understands solar inverters in great detail and he is not someone new to this area. You are projecting your own thoughts on me and being offended with no reason because I didn't mean anything offensive.

[@andred3199]

@@saif080 thanks for your explanation, didn't know that about your history. Just that I've heard people tell me and friends they're impressed with our ability to speak good English and it's often coming from a position of condescension, like they expect us to speak in grunts like animals and here we are speaking English, and good too. Apologies for any offence, hope it's accepted.

[@Prince-wx5yy]

Hello Dr Solar. I was really disturbed when I read the title on your video. I am looking at buying this inverter, and was very relieved at the end after watching your video. Please interrogate further on this, and also will recommend type1 SPD as a first line of defence in any system hooked up with our unreliable grid system. Many thanks for sharing your experience.

[@drsolar]

Hello Prince. This customer likes to play with the settings. We are going to add additional protection on the AC side. He is is not the only installation in the estate he lives in. He is the only one that likes to change the settings. I wish he could tell us what happened. He refuses to come clean. The inverter has been very bullet proof and we might be the first such failure in a while. Please feel free to purchase one. They are well built

[@drsolar]

Thanks Frank. All is well. How are you folks in Canada?

[@EjitEnergy]

Hello Chris, hope the client has a good earthing system? The reason is, since its the SPD section of the inverter that got blown. I have seen the inside of Deye inverter, I most tell you, it's well made.

[@drsolar]

Thank you for watching and commenting. I am still in shock the inverter failed. The tech team in China knew about it before I reached out to them. They asked if I had tried to change settings. This customer like to adjust settings. We did earth on the DC side and the AC side is earthed. We will verify the AC side again. I am still scratching my head.

[@EjitEnergy]

@@drsolar If and only if the customer can come out clean, it will go a long way to diagonalized what went wrong. He should not be messing with settings he doesn't understand.

[@adon8672]

Nice video as usual Dr Solar. I can only say God bless the Chinese. They really can be very hard working and committed. Looks like you need a few more solar panels. LiFePO4 batteries have nearly the flattest discharge curves of all battery chemistries so voltage is not a very accurate indicator of capacity. It appears the inverter was using the voltage to guess or approximate the battery capacity, a method which will be rather innacurate with this chemistry. I was thinking that batteries of the BYD, Pylontech and Dyness class will have CAN/RS485 or other ports that communicate accurate values of their SOC to the inverter. Is it that you aren't using the battery communication cables to the inverter or the batteries are reporting misleading values to the inverter? Need to install a shunt?

[@drsolar]

Thank you for watching and commenting as usual. The inverter and battery communicate. However the battery needs to get to 100% for the BMS to calibrate.

[@tirivaenim]

Greetings Dr. solar, but would a shunt with a BMV not help as a secondary source of measure?

[@drsolar]

@@tirivaenim it would help. I have one already just need to connect it.

[@kalliebotha5242]

Good day, thank you for the good video. Have you stress tested the Deye 5kW in a off-grid scenario? Resistive, Capacitive and inductive load test: for example a continues mix load 4kW output from the Deye then add a 1kW inductive load to surges to 8kW then stabilize back to 5kW?

[@drsolar]

Thank you for watching and commenting. We have had two AC s a water pump and hot plate run at the same time with no problems. One 1 he inverter AC and a 1.5 he window unit. I hope this satisfies your request

[@marcoa.rosado4724]

Nice, let us know what actually cause the inverter failure. People tend to push them more. Also don't rely on SOC only, 49v is definently not 73%. I usally look at volts then SOC.

[@drsolar]

Hello Marco this customer does push and likes to play with settings. I have always known that the SOC can deceive. Dyness said to fully charge the batteries to allow the BMS to calibrate.
