Battery Capacity is measured by WH. Learn by example: A 500 WH battery can run a 500W device, for an hour. When shopping for battery power stations, look for its Capacity. More capacity is better, but keep it mind it adds up weight. So, look for the weight as well.
Dust-off your physics knowledge. W=V*A. Learn by example: A 480W device will draw 10 Amps current, from a 48V battery. Solar panels are rated for maximum Wattage it can produce. Your battery power station will have a maximum amperes and maximum voltage limits, it can safely handle.
