Sunny Boy Grid-Tie Inverter - 1800W (1800U)


The Sunny Boy 1800U grid-tie solar PV inverter offers more flexibility for small residential customers. Its 120VAC output is perfect for most homes and small businesses, and its lower total output power is ideal for smaller, more affordable systems.

Housed in a watertight, stainless steel enclosure, the Sunny Boy 1800U can operate in extreme conditions (ambient temperatures of -13°F to 140°F). It's designed to support PV modules in series, increasing efficiency and eliminating the need for expensive DC distribution systems and cabling, and can even be mounted right on the roof along with the modules.

State-of-the-art maximum power point tracking performance results in greater real-world energy capture than any other grid-tie inverter. Sunny Boy's safety and reliability record is also exceptional, due in part to their inverters' redundant grid monitoring and built-in ground fault detection and interruption protection.
