Datouboss Reviews 

It was cheap and fast shipping, but that's where the good experience ends.
After 5 months of light use, the battery terminal melted internally and the controller started charging the battery at a reduced rate (no errors).
I contacted the support, which replied in a few hours asking for more info.
Upon providing the required info, I'm sitting 2 weeks with equipment I can't use on my off grid setup, and they haven't replied.
No matter how cheap, I would not buy again or recommend :/

Hello,

I bought a 6200W hybrid Inverter inverter and a 16KW battery. When I tried to commission the inverter with the battery, the inverter went into fault mode with fault code 08. The battery is also in alarm mode, with the red LED on the battery lit.
I have sent several emails to DATOUBOSS customer service since 3 weeks, they ignore my emails, no reply till now.

I will like a replacement of the Inverter.

Give me a reply regarding my emails
Thanks

I purchased a 12k split phase inverter months ago. It worked so well that I decided to expand my system to cover the whole home, so I purchased a 2nd unit. I had it over a month before getting around to the install. Unfortunately, I found shipping damage which caused the screen to only display on one side. After contacting Datouboss customer service & providing pics, they shipped me a replacement screen at no cost. The process did take some time (as the screen was shipped from China), but the repair was quite simple to perform. My system is working flawlessly now. I will purchase from these guys again, and recommend others do the same. You can't beat their bang for the buck, and they stand behind their products!

After Jiri Bekr presentation I was motivated to buy your inverter fkr cost effective and quality off grid cottage system.

DatouBoss Will NOT Service Your Warranty Claims. I bought 3 x DatouBoss DT-3U-48V 100A-A which is 51.2V 100Ah LiFePO4 Battery in a 3RU Rack. DatouBoss no longer seems to sell my battery and have remove all references and information from their own website. However, the same company who needed to service my battery will need to service you if there are problems with their products and I'm here to warn you that you may get similar results as me on these expensive items.

I bought it from Temu and in 4 months with about 60 cycles, one of the battery packs was discharging quickly and had Cell Under Voltage (CUV) error and shutdown. My battery pack is built with 16 x 3.2V 100Ah prismatic LiFePo4 cells in series. One of the cells started to fail and had lower voltage and less capacity than the rest of the cells. For battery packs in series, if one battery cell fails, the whole pack fails.

Over the next two months (the time is mostly my delay) we exchange e-mail to diagnose the problem including opening the unit up and possibly soldier a connection. Personally, I don't think a company should ever ask you to open a battery up and probe with a multimeter and soldier, but I'm quite handy in this area so I did it. The connection was fine so no soldier was needed and using a multimeter, I was able to verify that one cell's voltage was low. Eventually, we concluded the battery was faulty, though they never stated so, and told go back to Temu for after sales support (6 months after I purchased it). Of course Temu is not going to handle a purchase 6 months ago. Multiple message back to DatouBoss resulted to no more replies.

Bought a 48v 314ah battery, 11kw hybrid inverter and wifi module on 27th September off the Datouboss official website. All items were despatched separately. The inverter arrived damaged so I contacted customer service with photos. It looked like the unit had been dropped and the main control board and power supply had completely sheared from the case and had been rolling around inside the metal case. The unit also had other UK customers names and addresses so had been returned previously and also looked like it had been fitted previously. They suggested I plugged the unit in but due to safely concerns and the fact the battery hadn't arrived and equally wouldn't want to damage it I asked for a replacement. They then tried offering a partial refund but due to the damage and safely concerns around the internal electrics being damaged I asked for a replacement inverter so they sent a returns label and the unit was returned to them and arrived on 5th October. I contacted them on 7th, 12th and 14th October asking for a replacement or refund but they have ignored my emails and messages.

I appreciate parcels can get damaged by couriers but all Datouboss needed to do was send another unit or refund instead they chose to ignore all my emails. Very poor customer service.

The battery arrived a few days later and the wifi module arrived after a week. I now have an expensive battery that I cannot use and non existant customer service. They have my money but I don't have the system that I ordered.

I am now operating my AIO JC6016 off grid since Feb 26 and i couldn't be more satified. Quick delivery, product matches its description, easy to install and connect. Wi fi dongle took a little to setup but once is up and running is working fine. With some effort you can find all settings description on the web and easily manage peak shaving, time of use and other functions. Great value for money.

Just ordered something
So far , so good

Defective batteries with severed wires, poor soldering between the cells, and generally very poor quality. You could very easily lose your money.

purchased a 12V 300Ah LiFePO4 battery and charger from this seller.
The battery cannot properly support a normal fridge load, and the supplied charger failed to charge it properly.
I sent multiple videos and requested a replacement, but the seller has not provided a satisfactory solution or explained why their charger does not charge the battery.
Very disappointing product and customer service. I cannot recommend this seller.

It took a long time for the order to be dispatched. I started enquiring as to why it was taking so long, and it turned out the item was out of stock. It also took a long time to get a refund; I had to cancel the payment through my bank.

Unfortunately, when the Inverter Grid fails, it does not switch over within 10-20ms, but waits 1-2 seconds. Until then, there is no Load voltage.
The product works well other than that.

good products, bought battery and inverter, both work well. I would have just preferred the inverter connection cable to be thicker.

Good product, reasonable price.

6 months ago i buy a DT4862L 48V/6200W inverter from Datouboss.com. Good service and powerfull inverter. Package nice, robust construction and now with sunny day can charge ev and run home apliances together. Satisfied

Their batteries almost always arrive damaged.
If you ask for a replacement, they tell you to contact the website you bought them from.
If you bought them from their own website, they treat you with irony, telling you that their batteries are not compatible with your device, while they have previously assured you of this and are ignoring you.
If you want to lose your money, you are in the right place.
The response to my review is a complete mockery. Bear in mind that I made the purchase from their own official online store. I emailed them, and they replied claiming they bore no responsibility for the product; I even sent them a video, but from that moment on, they stopped communicating with me. They have all my details and try to put on a friendly front while constantly lying. Stay away from this store.
Anyone interested can have me send them the entire correspondence with this store, so they can see for themselves why they should stay away from them.

We are currently unable to process orders from Amazon, eBay, TEMU, and SHEIN platforms. If your order is not from datouboss.com, you will need to contact the platform you purchased from. We apologize that we cannot provide assistance beyond this. We recommend that you place your order through the official DATOUBOSS website.

The product is as specified.
16KWh 54V
It came inside a nice box and very quick.
Connecting two devices is as described in the manual.

I wasn't sure how equal they should be to connect them together, so a guessed <0.1V would be ok. That seemed to work. Whne i connected 2 of them they exchanged some amps but that was ok within a few minutes.

The build is a box on wheels that are ruggit.
The added cables and assaseries are also nice quality.

I connected them via a Deye inverter via RS485 (can-bus was not possible not sure why)
