Can you help me better understand the differences between the Fronius IG Plus 11.4-1 UNI inverter and the Fronius IG Plus 11.4-3 DELTA Inverter?
When would you use the 11.4-1 versus the 11.4-3?
Comments
The 11.4-1 UNI is a single phase inverter and can be connected line to line on 208 and 240V systems and line to neutral on 480V 3-phase systems. The 11.4-3 is a 3-phase inverter that can be connected to 208 and 240V 3-phase systems.
If you have a single phase system or a 480V 3-phase system use the 11.4-1. If you have a 208 or 240V 3-phase system use the 11.4-3.
