Hybrid Solar System
Best of On-grid and off-grid. Get full control over your electric power, while keeping you grid-connected just in case of emergency.
On-grid or grid-tie solar UPS are by far the most common and widely used by for homes and commercial purpose. These UPS do not require batteries and use solar inverters and are connected to the electricity grid. Whatever excess solar power is generated is exported to the electricity grid and owner get paid a feed-in-tariff (FiT) or credits for the energy you export.
But there is a challenge, On-grid solar UPS or Grid Tied UPS are unable to work or generate electricity during a blackout due to safety reasons. Since blackouts usually occur when the power grid malfunctions; If the solar UPS was still feeding electricity into a damaged grid it would risk the safety of the people repairing the fault/s in the network. It also stops working during voltage fluctuation. In both the cases there will be wastage of Solar Energy.
Off-grid UPS are not connected to the power grid that is why they require batteries for power storage. Off-grid solar systems must be designed such a way that they generate enough power throughout the year and have enough battery capacity to meet the home’s requirements, even in winters and monsoon when there is less sunlight.
High cost of batteries and off-grid UPS means off-grid systems are much more expensive compared to on-grid systems and so are usually only needed in places which are in remote areas and are far from power grid like vacation homes, resorts, farm houses etc.
A hybrid solar system has best of both On grid and off grid. It combine solar and battery storage in one and are now available in many different sizes and configurations.
Due to the decreasing cost of battery storage, systems that are already connected to the power grid can start taking advantage of battery storage as well. This means storing solar energy which is generated during the day and it at night.
When the stored energy is less, the grid is there as a back-up, allowing consumers to have the best of both worlds. Hybrid Solar System allow full control over your power, while keeping you
grid-connected in case of emergency. Hybrid Solar System generate power similar to a normal grid-tie solar system but use special hybrid inverters and batteries to store power for later use.
This quality to store energy enables most hybrid systems to also operate as a backup power supply during a power outage like UPS.
If there is a power failure or the grid becomes unstable the unit will automatically switch over to battery supply immediately and continue to operate independently from the electricity grid.
