Conclusion of YC600 vs. YC500i:
The YC600 and YC500i have similar output, but if you are looking at panels with a wattage of over 330W, the YC600 is recommended for your project with its higher peak output power and efficiency. Furthermore, the YC600 is recommended for installations requiring module-level rapid shutdown or compliance with California’s Rule 21.
