The further wind and solar generation pockets are from synchronous generation, the “weaker” the grid. The signal is then easily perturbed by power injection from wind and solar resources, making it hard for inverters . . In a solar + storage system, the inverter is the brain — but communication is the nervous system. When communication errors occur between the hybrid inverter, battery, BMS, or monitoring platform, even the best hardware becomes unreliable.
