I use two Power Queen 48V/100Ah batteries as an off-grid “mega power pack”. I charge the batteries with two chargers (5A and 20A) via smart sockets. I charge the batteries exclusively with solar power (which would otherwise be fed into the grid). I am using a 3000W inverter to convert the 48V DC to 230V AC. I use the battery power (via the inverter) to run my washing machine, dryer, iron and charge my electric car. I connect it directly to the inverter.

For the emergency power supply of my house, I set up a solar island system with 2x12V200Ah Plus and 4x12V100Ah Power Queen batteries (manually switchable).

Everything went perfectly. The battery is great and I received it within a few days of ordering.

Everything great! They fit perfectly in my closet and take up little space.

With IAN's help I was able to install everything perfectly. Delivery was quick and hassle-free and everything was well packaged.

Great app and battery as expected. Please note that it comes with BMS disabled and requires charging to unlock

My 12V island system supplies the circulation pump of the hot water solar system with the necessary electricity. 270W panels on the roof and in the trowel, two Power Queen batteries and the electricity for the pump is now free.

Top quality for a good price. The battery is working perfectly so far. Hassle-free and quick ordering process. The delivery time also corresponded to the information given when ordering.

I gradually expanded my capacity and bought one every month. I now have three Power Queen batteries. Honestly, they made my life a lot easier!

After two years of use, I am completely satisfied with the function and quality.

Excellent products at very competitive prices. With the appropriate Power Queen charger, everything is currently working perfectly.

The battery runs quietly at home and collects solar energy on sunny days to meet all my electricity needs.
