Frequently Asked Questions
Yes. The 48V 12kW hybrid inverter supports parallel connection of up to 6 units, delivering a combined output of up to 72kW. This makes it easy to scale your system for larger residential or commercial energy demands.
The inverter offers plug-and-play compatibility with a wide range of 48V LiFePO₄ batteries via RS485 and CAN communication protocols. Supported brands include Pylontech, Dyness, Fox-ESS, Gotion, Sunwoda, Voltronic, BST, Aoguan, Oulite, CF, Pace, AEC, and many more– ensuring hassle-free integration.
It features 4 charging modes(Solar Only, Solar Priority, Grid Priority, and Hybrid) and 4 output modes(Solar Priority, Grid Priority, Battery Priority, and Hybrid Mode). Additionally, you can program 3 time-of-use (TOU) periodsto charge during off‑peak hours and discharge during peak hours – effectively reducing your electricity costs.
You can monitor real‑time data either locally via the built‑in LCD screenorremotely through the mobile app (WiFi connection). For cooling, the intelligent variable‑speed fan ensures efficient heat dissipation while operating at an ultra‑quiet ≤40 dB– so it won’t disturb your sleep or daily activities.
Customers praised this inverter system for being "quiet and easy to set up" with impressive build quality. The battery provides excellent backup time and handles heavy loads smoothly. However, some shoppers noted the inverter outputs 10kW rather than the advertised 12kW. Packaging and delivery received positive feedback.
Muy bueno funcionando en mi casa hace 5 meses y todo perfecto
very well package Well built
Es una buena compra tremenda calidad necesito comprar la batería de 48 v de la misma marca y no e podido pero poco a poco la consigo
Product is as advertised. I’ve only self checked the batteries for now as I building complete 8KW off grid system and not done yet.
Been working great. I have 2 and plan on getting 2 more
Been working great
I a. Impressed with these batteries. Great quality. And the company is amazing. Customer support is responsive and accommodating. Highly recommend. I will build out my entire battery bank with these.
I purchased two batteries,,the package is good the only thing is the terminal short out my battery . The wire groundout on the 4 screw that hold the terminal down
I am really impressed with the quality of the Humsienk 48v 100Ah 3UServer Rack Battery.
I have installed it on a Dolly or Hand Truck. I also posted a video on my Youtube channel. http://www.youtube.com/@RednekGeeks
I have only been workingthis battery for a few days. Seems to work as advertised. Packaging was good and it arrived quickly in fine condition. My only complaint
Is that the included wires were a bit on the short side.
I plan on expanding my system and will be ordering more soon.
Works great with my xw pro 6848 inverter charger.
Very nice quality, wish had a few more, nice price, fixed income trying to lower electric bill
So far the batteries have been holding up. My house has been off the grid for a few weeks now. I bought 2 batteries that are connected in parallel now. However, I noticed that the voltage vs state of charge doesn't match up for both batteries.
Explanation: Battery A is at 94% with a voltage of 53V and battery B is at 84% with a voltage of 53V. So the voltages of the batteries are normally close but the battery percentage is different. I am not sure if that will eventually cause any issues
Overall, I'm impressed with the build quality/value when compared with other server rack batteries. There are a few things that can be improved, but it integrates well with my other batteries. The raised screw heads on the terminals should be re-designed so that they are recessed, and can't be inadvertently contacted, potentially causing a short.
On my initial charge, the cell voltages differed by over 200mv at the top. I did a capacity test from the initial charge & got 100.365 ah, but I had it set to cut off at 44.5v, instead of letting the BMS take it out. On the subsequent charge, cell differential was over 250mv at the top. I let it sit overnight, so the active balancer had some time to work. Next morning I took the cells up to 3.6v+ with a bench power supply set at around .25a. All cells were within 6mv, which is impressive.
I've ditched the factory app for monitoring in favor of the TDT "BMS meta" app, which allows control of more of the battery parameters.
At this price point, it's a winner - just change those screw heads on the terminals!
Humsienk 48V 8kW Hybrid Inverter | 120/240V Split-Phase, 10ms UPS, Dual MPPT
8k Humsienk split phase inverter with 4 Humsienk 48 volt Batteries and 14ea. 200watt bifacial solar panels. They run 3 Large freezers, 2 refrigerators and my washer and gas dryer, and gas furnace and lights. Thru a ten breaker transfer switch. I can be on Grid or off Grid with Humsienk.
Everything worked as promised. It has good features. I would almost say it's excellent for a budget brand battery.
fue muy rápido la entrega
I like the cabinet. It seems well made. While it is not terribly confusing to figure it out if you study the images well, I did not find an instruction manual for assembly anywhere (online or in the box) and while I am near certain I assembled it correctly, it does seem like I have two few machine screws and too many corner brackets. Again, there was not ANY instructions telling me one way or the other included, but it is a nice product.
Todo excelente estoy muy contento, nada más q una de los dos baterías no traía el cable de Ethernet 1pc.
El paquete llegó en excelentes condiciones además bien protegido
Works perfectly, it's quiet and easy to set up, also the info on the screen is just what I want to know.
I have20 600watts panels. Can it handle it.
And does it sends power back to the grid??
Yes, the 12kW inverter can fully support your setup.
To properly connect your 20 x 600W solar panels (12,000W total), we recommend splitting them into 2 strings of 10 panels each.
