HUAWEI - 4G Dongle

Le Smart Dongle 4G Huawei est un module de communication cellulaire qui connecte les onduleurs Huawei à la plateforme de monitoring FusionSolar via les réseaux mobiles 2G, 3G et 4G. Il se destine aux installations photovoltaïques où aucune connexion internet fixe (Ethernet ou Wi-Fi) n'est accessible à proximité de l'onduleur.

The module connects via plug-and-play to the USB port of a compatible inverter . Once the mini-SIM card (15 x 25 mm) is inserted and the dongle is powered by the inverter, a cellular connection is automatically established to the FusionSolar servers. Production and consumption data (if a DTSU666 meter is connected), as well as system alerts, are then transmitted in real time to the FusionSolar web portal and mobile app.

The dongle supports 4G FDD-LTE and TDD-LTE, 3G WCDMA/HSDPA/HSUPA/HSPA+, and 2G GSM/GPRS/EDGE standards , ensuring connectivity in areas with uneven network coverage. The automatic reconnection mechanism restores the connection after a temporary signal interruption, without manual intervention.

With an IP65 protection rating, dimensions of 130 x 48 x 33 mm, and a weight of 90 g, the Smart Dongle 4G remains attached to the UPS without altering the footprint of the electrical box or cabinet. Its typical power consumption of 3.5 W is drawn directly from the UPS's USB power supply.

The Smart Dongle 4G is compatible with the following inverters:

• SUN2000-(2KTL-6KTL)-L1

• SUN2000-(3KTL-20KTL)-M0

• SUN2000-(3KTL-12KTL)-M1

• SUN2000-(8KTL-20KTL)-M2

• SUN2000-(20KTL -40KTL)-M3

• SUN2000-50KTL/60KTL/65KTL-M0

It also supports third-party monitoring systems, subject to protocol compatibility with the SmartDongle. Huawei .

RECOMMENDED APPLICATIONS

• Residential installations where the home Wi-Fi network does not cover the location of the inverter (isolated garage, remote technical room, unserviced attic).

• Commercial and industrial rooftops without local network infrastructure near the inverter or connection box.

• Ground -mounted power plants and photovoltaic canopies where the deployment of a wired or Wi-Fi network would be disproportionate to the cost of a 4G connection.

• Agrivoltaic projects in rural areas with mobile coverage but no fixed internet connection.

• Sites under operation and maintenance (O&M) contract requiring real-time alert reporting to a monitoring portal.

• Replacement or supplement of a Smart Dongle WLAN on a site where the Wi-Fi connection is unstable or has insufficient range.
