eBean250 Energy Storage System 250W 314Ah Cell

The eBean250 is a compact energy storage system rather than a lighting kit: a sealed 250W unit that charges from a solar array or from the mains and gives back 220V AC at 50Hz. It appeals to households riding out outages, traders keeping tills and lights on, and field teams needing power away from a socket.

Its battery is a LiFePO4 cell rated at 314Ah and 3.2V, and this is the figure to compare against other backup units, since it sets how much energy the box holds. Charging is flexible: PV input is rated at 200W within a 12 to 36V window and up to 10A, while AC charging runs at 250W with a 176 to 264VAC input range and a 500W maximum input power. Output is capped at the 250W rated power, so it is sized for lighting, phones, routers, laptops and similar loads rather than heavy appliances. The unit measures 310 x 194 x 137.5mm and weighs 10.1kg.

Operating temperature is rated from -10 to +50C. The manufacturer states a 3 year warranty.
