I've installed many inverters with total success. But SMA has been an extreme disappointment. Selling Sunny Boy inverters could be the biggest mistake I've made in this business. Not only are the features of the inverter inferior to any other brand I've used, but their lack of effective support for the diagnosing issues is an major let down.<br /><br />Expectations for a Sunny Boy should include: high-pitched inverter sound, problematic, complicated and expensive rapid shut down system, poor range for wireless connectivity, very long wait times for customer service, and an unhappy customer.
