How Long Can a Solar Generator Run?

A solar generator can run on a single charge for up to seven days if the battery storage capacity is large enough, depending on what a solar generator is used for. Most residential solar generators will have a battery that is measured in Watt-hours. This unit of measurement calculates the number of hours the generator can power a device of specific and known wattage.

For example, a solar generator that can charge to 400 Watt-hours could power a 100 Watt device for four hours or a 400 Watt device for one hour. Different generators will have varying size batteries and, thus, various capacities.

Larger solar generators may be able to power a full-size refrigerator for up to 36 hours, while smaller devices may only be able to power a television for a few hours. Solar generators can also charge devices like mobile phones, tablets, or laptops. Large solar generators can give a laptop up to 98 charges, while a smaller solar generator may only be able to charge a mobile phone up to 16 charges.

For most mid-sized solar generators, proper use and careful rationing can allow a fully charged lithium-ion battery to last up to seven days on a single charge. The solar generator may sustain one small appliance and occasional mobile device charges during this period.

Understand that even the most capable solar generator will have limitations and cannot fully support a single large-scale appliance long-term, let alone have enough power to support an entire home (find more info here: Can a Solar Generator Power a House?). Although lithium-ion batteries are powerful, they do have limitations.
