Gas Generator Info

Most off-grid solar systems are paired with a generator. Without utility power as a fallback, off-grid setups need a backup plan in case their solar system can’t produce enough to meet the property’s needs.

Gas generators are used in off-grid systems as a backup charging source to recharge the battery bank when solar can’t keep up with demand. They are also used for backup power in case equipment fails and the inverter system needs to be bypassed.

As a general rule, the generator should be around 2x the size of the inverter’s continuous output. For example, a 4,000-watt inverter should be paired with an 8,000-watt generator. This allows the generator to power appliances and charge the battery bank at the same time.

Generators can also be used as a backup power source to supply power to grid-tie properties during an outage.
