The SMA Sunny Boy Storage offers an AC coupled architecture, enabling installation at any point in time. This provides greater flexibility and gives installers the opportunity to generate new business with existing customers. Davis Electric experienced this first-hand with one of their customers in Wichita Falls, Texas.
In 2017, a homeowner contacted Davis Electric asking for a grid-tied ground mount PV system for net metering. At that point, Davis Electric installed a 15kW solar array composed of JA 330W modules and two SMA Sunny Boy 7kW inverters.
Changes in the rate structure motivated the customer to call the installer again, this time for a retrofit with zero-export capacity. Davis Electric contacted CivicSolar asking for the most cost-effective, versatile and innovative residential storage solution available. The SMA Sunny Boy Storage was the perfect fit for this task.
In late 2018, Davis Electric paired an SMA Sunny Boy Storage inverter along with an LG Chem battery to reduce the export on nights and weekends.
The AC coupled design architecture for new PV systems or retrofitting existing ones is one of many benefits of the SMA Sunny Boy Storage. The quick and easy installation is also a huge help, especially for installers. ” We could install one in a half-day,” explained Davis Electric Director of Solar Nick Gilleland.
Other great features include multiple configuration options and the ability to expand. This client, for example, installed one battery but could ultimately install up to two more batteries for a total of three. This would allow for more power and energy capacity.
A high level of system integration provides unmatched monitoring and control and the energy management functions for many different applications are additional advantages of this SMA residential storage solution.
