![]() Typical ranges are 500W to 3000W for home use and smaller generators. More wattage means more power but at a higher cost and size/weight. Power output (wattage) - Determine how many watts of power you need to power your essential loads. ![]() Important considerations when buying home backup generators Inversion and power output - An inverter converts the stored DC power to alternating current (AC) that is used to power loads or supplement grid power at typical home voltage levels (120/240 volts).The more battery capacity, the longer the run time. Energy storage - Large lithium-ion batteries store the DC power generated from the solar panels during the day to use at night or during an outage.At night or in poor weather, solar generation stops and the system relies on stored battery power. Solar generation - Uses photovoltaic solar panels to generate direct current (DC) electricity from sunlight during the day.Home backup generators operate in essentially the same three stages as standard power supply chains, but have some key differences: A home backup generator provides this backup power. May be required for medical needs - Some people rely on equipment like CPAP machines, oxygen concentrators, refrigerated medications or other life-sustaining power sources during an outage. ![]()
