A Bi-Directional System combines the best of both worlds. It is a combination of a Hybrid System and Grid-Tied System. Bi-Directional systems allow the user to reduce electricity cost and still have backup when the power goes out.

Unlike a traditional Grid-Tied system a Bi-Directional system will still function even if there is no power from Eskom. Batteries will be installed to provide backup in case of an interruption in the Eskom feed. Two inverters will be installed, one dealing with the batteries and one dealing with the Grid-Tied component.

A Bi-Directional system is ideal for both commercial and residential clients who need to reduce cost but still be able to function during load shedding.

Bi-Directional Systems have 2 components. They consist of a Hybrid component and Grid-Tied component.

The Hybrid component is responsible of making sure the batteries stay charged. Power generated from the solar panels is usually stored inside the batteries. DC power from the batteries and solar panels will then be converted to AC power for the system to distribute. Eskom will be used as a secondary power supply. When the power goes out the system will start to drain the batteries. This will provide backup power.

The Grid-Tied component will be used to reduce electricity drawn from Eskom. During the day power generated by the solar panels will be distributed. If the load needed exceeds the power that can be generated be the solar panels Eskom will be used to supplement the system providing the needed power. This means that during the day less power is drawn from Eskom and this will reduce your electricity cost.
