SUNNY TOWER-US. SMA America, LLC

The UL certified, flexible solution for commercial PV systems

Designed with the installer in mind, SMA has combined ease of installation, a low cost per watt and high efficiency in the Sunny Tower-US. The UL and CSA compliant inverter system can be pre-configured in any combination between 30—48 kW. Its modular design eliminates the need for cost-prohibitive heavy machinery, as is required for large central inverters. It allows installers to apply their existing experience and tools in the residential market to attract commercial grade projects, all while benefiting from the Sunny Boy’s world-class efficiency and SMA’s industry-best reliability.
