Alternatively, it might be a good idea to invest in a backup generator. If you live in a place that doesn’t always have sunlight throughout the year, you’ll need more battery banks to prepare for consecutive days of lack of sun exposure. This electricity undergoes a conversion process into AC current using an off-grid inverter to bring power to your home.īy storing electricity in its battery bank, this system allows your home to run exclusively on energy from the sun even during the nighttime or on cloudy days. The charge controller limits the electricity stored in the battery bank and protects it from overcharging. Off-grid solar system works by taking energy from solar panels and using it to charge a solar battery via a charge controller. This system is more complicated, and therefore more expensive, compared to its grid-tied counterpart, and is made up of the following components: Off-grid systems are completely disconnected from your power utility grid relying solely on sunlight as its main energy source and making your system entirely self-sufficient. Grid-tied systems are also the more budget-friendly option since you don’t have to buy an expensive battery backup system to store excess energy. In case of insufficient solar energy, such as during nighttime or cloudy days, the inverter switches back to its grid power source. Lastly, the power meter measures the power to efficiently calculate the electricity generated by both the grid and solar system. The inverter turns DC into AC (alternating current), which runs through a switchboard to power your home and appliances. The system starts with its solar panels that harvest and turn sunlight into DC (direct current).

Grid-tie inverter (GTI) or microinverters.This system is made up of these components:

Its intelligent design allows it to know when power is available and when it’s not – synchronizing power delivery with grid power. Grid-tied solar systems work with your home’s power supply to deliver as much energy as possible. Sometimes called on-grid or grid-feed, this system is the most popular and common in both homes and businesses.Īs its name suggests, a grid-tied solar system is linked to your local utility grid.
