SMA External WLAN Antenna

The SMA External WLAN Antenna is built to help you boost the wireless connectivity of your solar power system. This complete antenna and accessory kit gives your inverter a more reliable link to your existing Wi-Fi network. This helps improve reliability and ensures you can monitor and optimize your solar power system using connected apps and website portals. While this might sound like a frivolous addition, being able to monitor your system can help you build a more efficient and powerful solar power system, so it’s not a feature you should skip in your system’s design.

The SMA External WLAN Antenna kit is an accessory that’s made specifically for SMA inverters that already have established Wi-Fi communication and an existing WLAN interface. So what’s the point of the antenna? If your inverter is tucked away in your garage, an enclosed room, or another spot on your property where signals struggle to reach—common for inverter installations—the built-in antenna may not be reaching far enough. This kit gives you a dedicated external antenna with a nearly 10-foot-long cable so you can mount it wherever it gets the best signal. The kit also comes with a mounting bracket so you can place it on a wall, pole, or exterior location to maximize reception.

Here are a few benefits of adding a WLAN antenna to your inverter:

This kit includes the SMA External WLAN Antenna itself, along with a mounting bracket that can be anchored to a wall or mounted on a suitable surface. You’ll also get an antenna cable that’s nearly 10 feet long and ready for a quick and easy connection. A weather-sealed cable gland is included for routing the cable into your inverter if needed. And of course, you’ll get a detailed guide for mounting and connecting your WLAN antenna.

Before you buy, make sure your inverter is one of the supported SMA models, as this antenna does not work with inverters from other manufacturers or incompatible SMA series. You should also evaluate the area where you plan to mount the antenna to ensure minimal obstructions and a good line of sight; the better the placement, the better the connection. If the antenna is mounted outdoors, confirm that the cable and mounting are sealed and secured properly so they stay protected from the elements.

If you have an SMA inverter with a weak Wi-Fi connection—whether it’s installed in a basement, metal-covered structure, or an area with interference—the SMA External WLAN Antenna is the practical upgrade your system needs. It gives you the flexibility to position your inverter wherever it’s most convenient while still maintaining a reliable Wi-Fi link. Installation is simple and once the antenna is in place, monitoring and optimizing your solar system from your phone, computer, or other smart device becomes much easier.
