Pedro Costas' Power Queen Emergency Power Backup System
I am a retired aircraft mechanic technician living in Puerto Rico.
I came across Power Queen batteries while searching on the internet.
I was looking for a battery with a 200A BMS and a 2560W max load, with a high life cycle, to run my solar power equipment—a 4000-watt inverter with several 400-watt solar panels.
Since I live on an island where frequent tropical storms and hurricanes occur, I needed a dependable battery to get me through hurricanes and power outages.
After doing research with my brother, an electrical engineer, we found out about Power Queen on the internet.
We decided on Power Queen batteries to run my solar power equipment at full load with a heavy-duty battery.
I needed a battery with a high cycle life and high BMS capacity for my emergency electrical power backup system.
Power Queen runs my equipment reliably.
Power Queen batteries meet 100% of my power requirements.
