Grass Val­ley-based start­up Box­Pow­er deliv­ers ener­gy in a box

Box­Pow­er’s mod­u­lar sys­tems are plug-and-play solar solu­tions that start at 3.5 kilo­watts (which can run most devices in small homes with 2–4 res­i­dents). The refrac­to­ry and water­proof box­es include solar mod­ules, invert­ers, bat­tery stor­age and an emer­gency gen­er­a­tor (pow­ered by diesel or propane) with an option­al mon­i­tor­ing con­trol system.
