A off-grid system may be practical for you if:
Being off-grid means you are not connected in any way to your grid’s power system or utility company. This is appealing because you are 100% self-sustaining your energy use.
Off-grid systems/hybrid systems, combine two or more modes of electricity generation together, using renewable technologies such as solar photovoltaic (PV) and wind turbines. The systems provide a high level of energy security through the mix of generation methods, and often will incorporate a storage battery system and/or small fueled generator to ensure maximum supply reliability and security. They combine the advantages of (PV) island systems and (PV) grid-tied systems, namely battery backup for essential appliances offered by island systems and lower installation and operations outlays offered by (PV) grid-tie systems. It also avoids the loss of unutilised green power by being grid-interactive whilst at the same time supplying power to both essential and non-essential appliances. Unlike with island systems, batteries will not be used when grid power is available, thereby maximising battery lifetimes.
Also, unlike with grid-tied systems the Hybrid system autonomously switches to island operation in cases of grid power failure, which means that your green power will be available even during power outages. The batteries are sized to maintain all the essential appliances in case of grid power failure.
