I wanted to build a versatile yet mobile power station that I could use around my house, so I built it on a hand truck. One of the main reasons I built this power station is because I wanted to have backup power that did not rely on fuel.
The system can power AC appliances from the inverter and, at the same time, power USB devices directly from the battery without using the inverter.
The power station can produce around 8kWh of power on average per day and is based on the MPP Solar PIP LV2424 MSD all-in-one inverter/charger (PDF Manual).
The DC side uses buck converters to convert 24V to 12V DC that powers a USB panel. This lets me power any USB device. This system is connected to 2000 watts of solar panels. It includes two 200AH Ampere Time 24V batteries connected in parallel.
I have include a detailed schematic of the entire system below.
