What is hybrid inverter?
An inverter is a critical element of any solar system, and you need it to convert the direct current (DC) electricity generated by your solar panels into distributed current (AC) electricity for your equipment. However, you’ll need a separate battery-specific inverter to convert power back and forth from AC to DC for battery storage and discharge if you install a solar panel system with a traditional inverter and decide to add it later battery system. Hybrid inverters, also known as hybrid grid-tied inverters or battery-grounded inverters, combine two separate elements (solar inverter and battery inverter) into one device.
However, there is no need for a separate battery inverter when you pair a solar panel system with a hybrid inverter, which acts as both an inverter for solar panel power and a solar battery. Importantly, while hybrid inverters are designed to be integrated into warehouses, you can install the technology without batteries; in fact, many choose to recommend installing a hybrid inverter in case a battery is added to the system in the future.
Benefits of Hybrid Inverters
Hybrid inverters have many advantages – here are some key ones to consider when comparing inverter solutions:
Elasticity
A common misconception about solar power is that if you install a system, you will always have power during an outage. In most cases, this is not the case: Traditional grid-tied solar inverters automatically shut down during a power outage, cutting off the generation of electricity from the solar panel system, as a safety precaution. Still, a hybrid inverter paired with a battery is an excellent result if you want to keep your property running on backup solar power during grid outages. Some hybrid inverters have both on-grid and off-grid capabilities, allowing you to keep using solar power when the grid goes dark.
Monitor
With a hybrid inverter, all of your solar power—whether fed into the grid, used for your own use on your property or stored in your batteries—is converted by a single element. This allows for “centralized monitoring”, meaning you can cover your solar panel system and battery performance from one platform.
Retrofitting Battery Storage Units
One of the greatest benefits of a hybrid inverter is that it combines the functions of two separate biases into one. This could mean an easier installation process for your solar installers. Depending on individual component prices and labor costs, you can save by installing a hybrid inverter at launch rather than paying for a solar inverter and a battery-specific inverter separately. However, if you are not planning to add a battery bank to your system, compare hybrid inverter solutions with traditional grid-tied solar inverters as they are less costly.
Disadvantages of Hybrid Inverters
A hybrid inverter is not the right solution for every solar panel system; here are some disadvantages to keep in mind:
Application of Existing Solar Panel Systems
The easiest way to do this though is to install an AC-coupled battery with an inverter if you previously had a good solar panel system and want to add the battery. Since your solar panel system previously had its own grid-tied inverter, swapping out this element for hybrid results would require rewiring and labor, adding to the cost of the solar-plus-storage system.
Equipment cost
Adding a mongrel inverter and battery to your system has an advanced outspoken cost than installing a separate grid-tied result. This redundant cost is worth it if you witness frequent outages or want to use batteries for electricity bill arbitrage; still, if your mileage company has favorable net metering impulses and the grid in your area is dependable, traditional grid-tie The outspoken cost of a solar panel system will be lower.
Future Design Flexibility
Not all hybrid inverters are battery agnostic. Some energy storage systems, such as Sonnen eco, already have an inverter built in, eliminating the need for a hybrid inverter. If you preemptively install a hybrid inverter, keep in mind that your options may be limited when it comes to future storage technologies.
