Introduction
At first glance, AC operated LED seem the perfect choice for AC off-grid systems. Their efficiency can reach 120-160 lumen per Watt (as per 2017), their life expectancy is claimed to be between 20'000h and 50'000h, largely exceeding in both regards any competing technology like fluorescent, sodium arc or metal halide. Compared to the latter two, LEDs also are much more scalable (from few Watts to stadium lighting) and demand less careful operations.
Issues with LED lights in AC off-grid applications
Any relatively small amount of LED lights in an inverter based off-grid system (small meaning total power consumption of the LED lights as compared to the total inverter power) poses normally no issues.
