A Grid-Tie inverter supplements your mains utility power with solar power. In order to achieve this the electricity produced by your solar panels is converted from direct current (DC) to alternating current (AC) by the grid-tie inverter. This system is ideal for businesses who use most of their electricity during the day. The system allows for self-use consumption when you use most of your electricity.
Grid-Tie systems are the most cost effective and easiest systems to install. However, in a pure grid tie system you will have no power supply if there is loadshedding. To solve this problem, you can connect the IG series PV inverter to the output of the TBB Kinergier Pro bi-directional inverter to compose an AC-Coupled system.
The TBB IG series inverters are designed especially for AC coupling, featuring great system stability and extraordinary dynamic response.
