The Bottom Line

The DELTA 2 makes sense for buyers who want capable 1800W output in a slightly lighter package and have no need for high-surge appliance starts. The DELTA 3 Plus suits users who prioritize longer cycle life, stronger surge capacity, and broader device compatibility, especially with its 1000W solar input ceiling that doubles what the DELTA 2 accepts. Our pick is the DELTA 3 Plus for its measurable advantages across durability, solar flexibility, and real-world device support.
