The reasons why Hybrid Inverter should be used?

31 Aug 2021

The Solar Inverter is an integral part of the entire power system. There are plenty of options available when it comes to selecting a solar inverter: these inverters vary in size, efficiency, performance, and capabilities. If you’re thinking about adding a battery to your solar panel system now or in the future, you may want to consider installing a hybrid inverter.

What is hybrid inverter:

An inverter is a critical component of any solar energy system. As all the home appliances run by alternating current (AC) and the solar generated energy is direct current (DC). So, to operate the home appliances easily, inverter plays a vital role. If you install a solar panel system with a traditional inverter and decide to add a battery system later on, you’ll need a separate battery-specific inverter to convert the electricity back and forth from AC to DC current for your battery to store and discharge. inverter’s efficiency is all about the power it takes from the solar panels, and converts into usable AC power. An efficient inverter reduces the loss of energy that usually happens while receiving DC from the solar panels. Usually many people choose to install a hybrid inverter preemptively in anticipation of adding batteries to their system in the future.

Why to use hybrid inverter:

In the old days, off-grid batteries were DC coupled. In domestic settings, more recent batteries are AC coupled, particularly when retrofitted to existing solar systems with AC inverters.

Conversion between AC and DC (or vice-versa) will result in some power loss. For comparison, here’s a DC coupled battery with a hybrid inverter:

And here’s an AC coupled battery with solar and battery inverters:

As you can see, energy going to the battery in the AC coupled example has to be converted twice (DC-AC then AC-DC), increasing the losses. Then when you come to use that energy, it has to be converted again (DC-AC), adding even more loss into the system. So in total, a DC coupled system has one conversion, while an AC coupled system has three. Which indicates, using hybrid inverter incurred less loss.

Other notable important features:

Helps to "centralized monitor" the system, which means the performance of both solar panel system and battery can be monitored with one single platform.

One of the biggest benefits of a hybrid inverter is that it combines the functionality of two separate pieces of equipment into one. This can mean an easier installation process for your solar installer.

Save money on your power bills by increasing the proportion of self-use electricity (also known as self consumption) generated by your solar system from 30% to more than 70%. Flexible settings for charge and discharge times allow you to tailor energy usage to your requirements and also charge your battery from the grid at off -peak periods.

Save money by becoming independent from ever increasing energy prices. With the advent of the 'smart grid' hybrid inverters, homeowners and businesses to take advantage of changes in utility electricity rates throughout the day. It'll be possible to draw upon deployed battery stored green electricity while electricity is expensive, then switch back to the grid when it is cheap.

Keeping all of those factors precisely, choosing hybrid inverter is the best solution for any solar solution. EverExceed EHCS series inverter can be a good friend of yours while deploying for a hybrid system solution.
