Ginlong (Solis) Technologies Co., Ltd. Reviews 

Needed information about the connector type for the inverter I have. They told me to contact the distributor. Because the actual manufacturer does not know what the connector type they use? Anyhow, poor service.

Amazing customer service , due to my own installation errors my system was working correctly,a few messages to solis had it sorted .
No fuss no bother just sorted , always responded quickly and professional
I would recommend them purely on the CS and the great build quality

I had Activ8 install my PV solar system in Portmarnock about 3 years ago, and unfortunately they took my accessory box away with them on completion, and I recently needed to use my AC Backup connection to add circuits using Batteries in the event of outage. Activ8 said they would contact me and deal with the missing part, and I had no part number, so they failed to follow up, so I contacted Solis (Ginlong directly and they were just great, and posted the correct part to me after I filled in a warranty form. Very Happy with their responsiveness, and after care. Thanks Solis!!

I have call customer service 4-5 time and tried to get through to an engineer to reconnect my Data logger and what a palaver, its like no one give a ****. even asked the guy via emails to escalate it as they don't works after 4pm, the hours I am on site. There YouTube videos only part look like what I see on my phone app and don't take me through to the same screen as what there show you.
whish I had took the quote from my energy and the installer Copper Solar never gets back to me and Solis says I have to get in contact with the install
DONT USE THERE OF THESE TWO!!!

Solis have sent me yet another useless email show me how to reset the data logger (muppets).

Better recourse buying a 2nd hand one from Facebook Marketplace, than buying an expensive reputable brand, from a supposedly reputable company.

Solis hybrid inverter developed a fault by the 2nd day. Refused warranty RMA due to unconfirmed battery compatibility in a non-storage situation. They are requiring I buy a compatible battery to proceed further, even though Solis officially states and designs its hybrid inverters so that they can operate as standard grid-tied solar inverters without a battery attached.

Always make sure to pay by credit card (or just buy 2nd hand elsewhere) as warranty means nothing these days.

Dear Benelux Service Centre,
I am very disappointed. The system is NOT working.
I have paid 7000 Euro (invoice included) for a system that does not work, except occupying some place in my home.Helpdesk also NOT reacted to my calls for help
Can I return/give back the entire system? In the invoice included is stated that I have 10 years of warranty.
I would like my money back. I am a father of 6 children and I can spend my money on more useful things...

Couldn’t be more disappointed. I’ve had 2 Solis Alpha batteries installed and only 1 is functional. Initially the faulty battery kept tripping the system so it was not working at all. Now the installers have taken the faulty battery out of the system so I have one working battery. Have been waiting months for a resolution for the faulty battery but it is not forthcoming, despite repeated requests for a replacement under warranty.

Dont change your WiFi, its impossible to connect to a new network.

Its 2026 and I cant use an app to see what's happening with my batteries and solar.

Their customer service is non-existent. I have not even received a reply on my ticket since the last 26 days. Power inverter is a critical piece of equipment currently disabled since 1 month. I have even tried escalating to their escalate email but no use. What should I do?

I recently allowed a 3rd party to connect to my Solis inverter to allow my system to be integrated into a nationwide virtual power plant - congratulations Solis for supporting this. The connection created some issues with the inverter data logging, the inverter continued to operate flawlessly. Solis European online support resolved the issue within a couple of hours (during a weekend) of contacting them and applied a firmware update seemlessy and remotely. The new firmware fixed the original issue and added extra functionality to the inverter, I needed to contact Solis support again as there was a discrepancy in the data being logged, again resolved in just a few hours remotely. To be honest, I don't think I have ever had such a good service from any company, ever.

I've had to open a few tickets with Solis Support for various reasons.
Each query was handled professionally and really quickly, I was super impressed.
I have come to really appreciate the product (S5 5K hybrid inverter) and how it can integrate with so many battery manufacturers and models.

Systemic Helpline Failure in Pakistan – Ignoring Tier-1 B2B Installers

Review Body:
As an established solar professional and installer in Pakistan (Org Code: A30106 , I am deeply disappointed by the drastic decline in Solis’s after-sales support. I have historically trusted and deployed numerous Solis inverters across major commercial projects—including dual 125 kW installations—leaving a major tier-1 competitor because of Solis's previously excellent customer service reputation.

Unfortunately, their helpline infrastructure has completely collapsed. Today, I spent nearly 20 minutes in a queue on my cellular phone waiting for technical support, only for the inexperienced personnel to pick up, talk in the background, and abruptly hang up the phone without addressing my query. Operating a single-line helpline with untrained staff is unacceptable for a global brand.

I have urgent client issues pending on-site, and this lack of accountability is causing direct friction for my business. I have already issued a formal 48-hour notice to their regional and China HQ escalation desks

If a senior representative from the Pakistan team does not contact me directly to resolve this immediately, I will be taking this matter directly to the District Consumer Protection Court in Pakistan for deficiency of service, while permanently shifting all my future commercial clients to alternative inverter brands.

Solis will not survive in this market if they continue to treat their registered installation partners with this level of neglect.

My installer unknowingly fitted a Solis inverter that was "old stock" (held by the distributor for 13 months). Because of this, Solis initially short-changed my warranty, calculating it from the manufacture date instead of the installation date.It took a long dispute just to get them to honour the basic 5-year warranty from installation. When I wanted to buy the 10-year upgrade, Solis and their distributor were incredibly unhelpful, passing the buck back and forth.

Warning to homeowners:
Solis does not care about end-users; they only care about their distributors. If you are trapped in this "old stock" warranty loop, bypass their customer service entirely. Go to a third-party solar parts site and purchase the "Solis 5 Year Extension" directly using your serial number. It works instantly and saves you months of stressful emails.

We have a Solis Inverter and PureDrive battery.

We were let down by PureDrive, who made false marketing promises before we bought and had a scheduling algorithm that simply did not work.

We found out that we can ask Solis to control when our battery charges from the grid, which has been working perfectly now for a couple of months.

Solis are super responsive to email, answering questions and getting the job done.

5/5 stars, would Solis again

I bought my solis inverter just over a year ago. It was find until a week ago were it started to mess up. Their service team in IRAQ are a joke! They don't do anything, they just make you trying playing with it and hope that the problem will go away. I would NOT recommend anyone to purchase this inverter, because the company is not their to support you when there is a fault!

Tried to get them to change settings for my Inverter, what followed was a [Comedy of errors] i was given a second job no' & then told my changes would cause problems but they went ahead anyway & then gave a reel of possible problems. So unprofessional i did the job manually in 2 minutes. Email given does not recieve my emails.

I have always received great service from Solis. My industrial solar inverters have a 5 year warranty. Solis always reply promptly and very helpful. Solis have replaced 2 faulty inverters after 2 &3.5 years operation. No quibble. They even arranged the delivery and collection of the inverters by their own courier. That is how a warranty should work and great after sales by Solis.

Absolutely rubbish. con artists. Never worked from day one no support from company avoid at all costs. They will just take your money and you wont get any help from them again. Faulty systems breaking down catching fire. Stay away from these people

Problems with accessing the inverter. Company not interested. Fault with inverter but company expect end user to cover the cost of labour running in to hundreds of pounds even though fault with design and reliability of inverter. Will be replacing with a brand that back up there products
Avoid installing this brand

Avoid,
My inverter just started to charge and discharge all day for months costing a lot.
I called the help desk and nothing was achieved. I can only think that they did a firmware upgrade and all my settings did not retain. They did another update as per my request but that made no difference. Just powered and dumped to the grid all day long. I was away for work and came back to a massive bill. Not the first time it’s done what it wants so I think the updates can drop your settings.
I set to self use and disabled export but it still exports. I then just set export limit to 30w to stop the draining of the battery.
Shocking logic, some settings just don’t respond.i have the evidence and considering a claim.
