Quick Answer
Mount string inverters outdoors using a secure, weather-resistant mounting system that allows for easy access and maintenance. This typically involves a combination of wall or roof mounts and a sturdy enclosure.
Choosing a Mounting Location
When selecting a location for a string inverter, consider factors such as proximity to the solar array, accessibility for maintenance, and exposure to the elements. The ideal location is typically on a wall or roof facing east or west to minimize shading from nearby structures. It’s essential to ensure the inverter is at least 3 feet away from any walls, windows, or doors to prevent heat buildup and reduce the risk of overheating.
Mounting the Inverter
To mount the string inverter, use a sturdy bracket or clamp designed specifically for the inverter model. Secure the bracket to the wall or roof using lag screws or anchors rated for the weight of the inverter. When mounting multiple inverters, use a level to ensure they are aligned and evenly spaced. Consider using a single, large enclosure to house multiple inverters, which can help reduce the overall installation cost and improve aesthetics.
Additional Considerations
When mounting string inverters outdoors, it’s essential to consider additional factors such as temperature, humidity, and exposure to the elements. Use a weather-resistant enclosure or cover to protect the inverter from rain, snow, and extreme temperatures. Regularly inspect and maintain the mounting system to ensure it remains secure and functional. Consider using a UV-stable coating or paint to protect the inverter’s exterior from degradation caused by exposure to sunlight.
