I recently installed an 18k PV Inverter. The system has no batteries and is set up as a grid-tied system with a back-fed breaker. I installed it this way for easy future expansion.
When I turn the inverter on, the inverter is not communicating with the rooftop Tigo RSD devices and voltage is not flowing.
I must have the setting set up incorrectly for my configuration. I have been unable to get ahold of anybody at EG4 to double check my settings. Can somebody give me a hand? Thanks.
