WHAT IS A HYBRID SOLAR SYSTEM?

EDUCATIONAL EXPLANATION WITH OUR INTEGRATION COEFFICIENT IC MODEL

What is a Hybrid Solar System?

In the same way as the traditional system connected to the grid (On-Grid or Self-consumption), the solar panels in a hybrid system collect and convert sunlight into DC energy. In the traditional On-Grid system, electricity converted to AC is returned to the grid through central inverters or microinverters, allowing the user to live without batteries, save on their electricity bills, and access electricity from the utility during cloudy days or at night.

But in a hybrid solar system, the electricity, both from the AC grid connection and the DC solar panels, is directed to a so-called hybrid inverter-charger, which in turn is connected to a very long-lasting LIFEPO4 battery bank to manage its load, both from DC, with the solar panels, and from AC converted to DC from the utility.

Once the battery is fully charged through this process, both, together and separately depending on how the advanced charging system that this inverter-charger has been programmed by software, the excess is channeled through a bidirectional smart meter via net-metering to the network's AC power lines.

This allows the user to retain in the batteries a good part of the electricity produced during the day from the sun via solar panels or also from the hybrid inverter-charger, from the AC grid when this is cheaper. This helps to power the AC loads of the place (home, business, or industry) not only during cloudy days or at night but also when there are power outages.

As a side note, hybrid solar systems that store energy in a battery while remaining connected to the grid should not be confused with systems that use both, solar and wind energy in parallel, which are also often referred to as solar hybrid systems.

It is important to highlight that the name “hybrid” comes, first of all, from the fact that the connected AC load takes energy on a shared basis from all three main elements of this system: the commercial grid, the solar panels, and the battery bank, depending on how the system's operation is set. That is why you can see in the picture attached the 3-color AC line on the side of the connected loads.

Secondly, it is also observed that the batteries can be charged from both, the AC energy coming from the utility and converted into DC by the hybrid inverter-charger, as well as from the solar panels. In this case, the arrows point toward the battery bank showing two colors red and green.

Finally, the inverter-charger is capable of returning AC energy to the utility in On-Grid mode, through the net metering process, taking DC energy from both, the battery bank and also the solar panels, as seen in the arrows, light and dark red colors, towards the AC external electric pole.
