Excellent service, fast delivery and top quality.
Markus E.
I am happy with the Queen
Alexander W.
Thanks to Ian for help with the order
Norbert N.
Super fast delivery - well packaged - flawless workmanship - I can't say anything about the performance and durability yet - I I haven't used my two batteries yet.
Thomas S.
Like the other two orders, delivered within two days and great batteries
Knut K.
Everything works great, delivery went very well.
Matthias O.
Use as storage for excess PV energy, which is later used as night feed-in. Optimization of own consumption. Works reliably, no problems so far. I'm very satisfied!
Werner S.
Delivery: quickly without any problems
Operation: 2 hours in parallel without any problems
I'm happy so far
Norbert v.
Everything's great!!
Jäkel-Behringer M.
Everything's great!
Marcel B.
am very satisfied with the overall package, order delivery and quality
Christian B.
This is supposed to be a storage facility for our PV.
2x 25.6v a 100Ah connected in parallel for 200Ah.
This storage should only be charged with excess and will be discharged again at night.
The first battery was purchased at the end of December last year to test the system. A second one was added at the beginning of this year.
Everything fine.
Maybe the system will be built again to catch more overnight.
I am very satisfied.
Karl-Heinz B.
Order and shipping flawless.
Communication okay, questions were answered quickly.
So far, of course, no "long-term experience", but the batteries are well processed, BMS works, no abnormalities so far (2x 25.6V/100Ah in series, as solar storage).
Reinhold E.
Everything's great! The complaint was also handled without any problems.
Thomas S.
Battery was well packaged, German instructions with wiring examples and pre-charged to over 26V.
Bernd R.
The dimensions and performance are great.
Alexander K.
Super fast delivery and the battery is great and the quality is great would definitely buy again.
Dieter S.
fast delivery, everything is fine
Ralf O.
The batteries are quite OK. But customer service still has a lot of room for improvement. I would have liked more anger and accommodation in my "Delivery Crime". They always want the money immediately, only the customer can wait, I don't like that.
Maybe I'll order somewhere else next time.
Rüdiger B.
I'm still setting it up, good and clean workmanship.
Christian Z.
Good product at a good price :)
Peter K.
The battery has already been in operation for a month. I'm very satisfied. Excellent.
Michael W.
The battery was delivered very quickly, corresponds to the description, was charged, installed, connected and does its job absolutely perfectly, just as I imagined it would.
I'll buy one or two more soon when there's money left.
Holger H.
I really like batteries.
I have 3 of them in parallel.
Resulting in 25.6 V x 300 A = 7.68 kW
Gerhard G.
Warranty and returns very good
Herbert C.
Quick delivery. Battery well packaged. I can't say anything about the battery itself yet. Looks pretty good so far
Tim M.
Excellent customer service as you would expect! Quality and price performance top! Only recommended!
Viktor S.
So far I am completely satisfied, great product.
A battery has 0.3 full less displayed after one charge. I'll keep an eye on it, otherwise there's nothing to complain about.
Markus B.
Ordering process was great, I clarified many details via the chat and always received a quick response
Dieter B.
Very fast delivery, everything well packaged.
Viktor S.
I'm very happy satisfied. Would buy again.
Hans W.
Fast delivery, neat packaging, good documentation and technical description. A great product at a fair offer price. I'm thinking about buying a second one to expand capacity.
Karlheinz G.
I am very satisfied, but I would have liked the option of a BlueTooth connection to the BMS
Harald L.
Very fast delivery, very good and short instructions with the essentials. Battery does what it promises. Find it a top product at an acceptable price
Patrick E.
Top service, fast delivery and can do what was promised.
Adrian S.
Top goods and delivered super quickly.
Rainer M.
Great battery, does what the capacity information promises.
Harald B.
I am very satisfied, delivery was very quick, the price was very affordable due to discounts. Works without errors.
Jürgen L.
I built a storage unit for a balcony power plant with the Power Queen 25.6V 100Ah. So far the battery has delivered what it promises.
Dirk L.
The battery has now been in operation as a storage unit on a 1.7KWp solar system for about 3 weeks , and does what it's supposed to do.
Norbert v.
The battery works perfectly. Use it for night power supply with Hoymiles HM-400 (adjustable via OpenDTU) and as an emergency power supply with a UPS island inverter (ECTIVE TSI 15). Everything works wonderfully. Feed-in via solar controller is planned.
If you could query the charge status of the BMS, it would be optimal.
Tobias M.
The quality of the battery is very, very good. If you still have questions, you will receive great support from support.
Walter H.
Very good batteries.
Fast delivery.
Harald L.
Everything was uncomplicated. Description very good.
Mirko T.
Today my 24 volt storage device went online for the first time. The battery is charged using a cheap 60A charge controller and fuels an HM-600 which is limited to 120 watts for night power. See YouTube for video. I will now test the system first and then upgrade it to 48 volts.
Michael W.
Works perfectly and the price is good.
Jens B.
It's a good battery.
It works perfectly and does what it's supposed to do. Delivery was quick, all the necessary parts were included, and the product was well padded.
I will probably order again soon to expand my system.
Benjamin Z.
The shipping was fast and the battery is doing what it is supposed to so far.
Peter U.
I will use this battery for my night power supply
Marlies v.
Everything is OK !!!!
Armin G.
The two 25.6V 100Ah batteries were delivered individually and extremely well packaged 3 days after ordering.
An English and a German operating manual were included in the scope of delivery.
The majority of the nomenclature used in the English operating instructions can also be found in the instructions for the solar controller and the inverter.
I put the two batteries into operation according to the operating instructions and finally connected them in parallel.
I read the current data (PV, battery and load output) from the solar controller with a Raspberry Pi and write it into a time series database.
This means I can perfectly monitor the charge and discharge values.
I adopted the recommended battery parameters from the operating instructions for the solar controller settings.
I feed the inverter via the programmable load output of the solar controller.
So far the batteries are behaving as expected.
Frank W.
Visually attractive battery. Packaging was secure and therefore arrived without damage. Test and experiences later.
Knut K.
As you can see from the outside, the batteries are of good quality. The documentation is great. I've had it online for a week, so far everything's ok.
Martin R.
Unfortunately my project isn't finished yet. But ordering and delivery worked. Gladly again.
Christian F.
Very satisfied with the service.
Dirk W.
I charged the battery with 10 A. With a set maximum voltage of 28.8 V. The BMS switched off at just 28.2 V. I then applied 30 A (3 heating elements 25 V / 10 A) for about 3.5 hours. Even in the last 30 minutes, the battery voltage remained above 25 volts. All I can say is: Great! Hopefully I won't be able to report on the number of charge-discharge cycles until 10 years from now.
Heiko E.
I now have the 2nd battery 25 a few weeks apart Bought .6 V 100Ah and connected in parallel. The batteries are evenly charged with electricity, which indicates a balanced internal resistance. At night it supports my balcony power plant and everything runs great. I can't say much about large current draws from the batteries, as I use 100 watts for 12 hours a day. The price-performance ratio is top for me.
Matthias D.
Great service
Good advice
very good article 5.50 kW (pure off-grid inverter).
The system supplies permanent consumers in the house (freezers, refrigerators) and is intended purely as a PV charging station for our Dacia Spring. The car is charged with the mobile charging device (for Schuko sockets)
If the lipos are not enough, the inverter switches to mains.
This is how the electric car makes sense and it works.
Jörg W.
I'm very happy with the service and the battery so far
Gerhard D.
I've had the battery for a few weeks for "night power supply " in use and am very satisfied with it so far.
Juergen S.
Battery works perfectly
Ken B.
Everything was great from the order to delivery to the goods were great
Always happy again
Wolf-Dieter E.
Works perfectly on a DIY night feed system with a Hoymiles HM-300 inverter.
Patrick Alexander S.
Impeccable quality! Ordered a second one today.
A few more detailed information about gentler charging via MPPT controller would be nice. 30V charging limit and 21.6V discharging are pretty borderline ;-)
Heiko E.
I bought the battery to power my balcony power plant in less sunny places days to support. Excess PV power is used to charge the battery. The battery has a stable voltage and charging is also problem-free. I tend to work with lower powers (up to 200W) and therefore can't notice any drops in performance or heating of the battery. All attempts to cover these things with old lead batteries were short-lived and just wasted time. I'm already thinking about connecting a second battery in parallel...
Heiko M.
It does what it's supposed to. I am very satisfied.
Jörg W.
Highly recommended
Stefan A.
Delivery was fast and the battery works.
Björn H.
The device is charged via solar using a 20A charge controller and fed into the grid at night with a constant feed of 300W via an inverter .
The solar modules are so oversized that the process should work well even in winter.
Since the basic power consumption of the house is around 330W, no electricity is actually fed into the grid.
Joachim M.
Top product - everything works like me
I imagined it...
Sebastian F.
This is now the 3rd battery. I am very pleased.
Gerhard P.
Quick response from the consultant, fast processing and delivery, all OK
Günter N.
Hassle-free and quick ordering process.
The delivery time also corresponded to the information given when ordering.
Emails with questions after delivery were answered promptly.
The battery is working perfectly so far.
Harald R.
Does what it's supposed to and not bad.
helmut H.
I would have liked to give you 5 stars.
When I tried to buy a second battery I received no response. I have uploaded the completed form for the 0% VAT...
Please provide a short response!
Greetings
Björn B.
Use in a PV island system with another 25.6V battery.
It runs just fine and the specified capacity is achieved with ease.
Klaus H.
Fast delivery and good quality
Helmut R.
Very fast delivery and safe packaging! The battery has a high performance!
God S.
Everything is great
Reinhard B.
Everything's great, 100 Ah accurate and also measured! Daily function 100% accurate, discharge daily and so far no problem, thank you!
Sven R.
everything worked great.
good job!
keep it up
Christian K.
Super great product. The delivery worked perfectly.
Gladly again
Robert N.
So far everything is working perfectly. I used the battery to build a small storage unit with a plug-in solar system.
Ralf K.
Very good price-performance ratio. Absolute recommendation and I would buy again.
Klaus H.
Fast delivery, so far I can only say positive things about this battery.
Hans G.
The battery makes a valuable impression. It has been working without any problems for a week. The manual is good.

I am very satisfied.
Holger H.
Super fast delivery, in sturdy packaging. Everything looks valuable.
Works as planned.
Already my second battery 25.6/100AH.
Gladly again.
Joris M.
More than the promised performance, does not get warm when used, is well made and can be used continuously. I now have two to get to 5 KW.
Holger H.
The delivery was very quick and in very good packaging. Product does what it promises. I bought it for the second time.
Thomas S.
The battery does what it promises and there is nothing negative to report. The price-performance ratio is unbeatable!!! A very clear purchase recommendation!!!
Walter W.
I now use four LiFePo4 batteries from Powerqueen. So far there are no problems. They simply do what they are supposed to do.
Thomas P.
Works very well in my solar system :-)
