Grid connected solar inverters send the power from your solar panels to the power grid. Since these systems don’t have a battery to store the power, you will lose power to your house when the power goes out. Hybrid inverters are capable of adding a battery, so keep this in mind when choosing your new solar power system.
Hybrid Solar Inverter
Hybrid solar inverters connect to the power grid, but they can also have a battery system. Some systems, such as Redback, are modular. This means you can add the amount of batteries you require into a compact, elegantly designed unit. Software can be used to determine the most efficient energy use if you have a battery.
Off grid solar inverters allow you to run your home completely on renewable energy, because they have a solar battery system. Your batteries need to have enough capacity to store enough power to get you through those winter days with very little sunlight. Careful planning is required when you design an off grid solar system.
