The module that gives a Huawei inverter internet through a SIM card, where the fixed network does not reach. It plugs into the USB port, serves up to 10 inverters, IP65.
This is the part that connects the solar inverter to the internet using a mobile telephony signal, exactly like a phone with a SIM card. It is inserted into the inverter's USB port, without additional cables, and from there it sends the data about production and consumption to the manufacturer's app. It is the solution for places where there is no fixed internet: an isolated house, a hall, a farm, a plot of land. It also creates a local wireless network to which the installer connects with a phone in order to commission and configure the installation.
It uses an ordinary Mini-SIM card, of 15 x 25 mm, which has to be obtained separately, with a data plan; the traffic needed for monitoring is small. A single module can serve up to 10 devices, that is up to 10 inverters connected in cascade, so there is no need for one for each device. It normally consumes 3.5 W, that is less than an LED table lamp consumes, and works between -30 and +65 °C, so it withstands both the frost and the inverter heated up in summer. The 162 x 48 x 28 mm housing has IP65 protection and an LED that shows at a glance whether the link is active; maintenance amounts to checking the validity of the SIM card.
Model SDongleB-06, plug-and-play USB interface on the SUN2000 inverters, with cascading on the RS485 bus for a maximum of 10 devices. The European variant covers LTE-FDD B1/B3/B7/B8/B20/B28, LTE-TDD B38/B40/B41 and GSM 850/900/1800/1900 MHz; AP-type WLAN module for local commissioning from the FusionSolar app. The data is transmitted to FusionSolar Smart PVMS or to third-party monitoring systems. Humidity 5-95% RH, storage -40...+70 °C, maximum operating altitude 4000 m, CE, RCM and TELEC certifications.
Suitable for any installation with a Huawei SUN2000 inverter located where there is no fixed internet or where the house's Wi-Fi signal does not reach the inverter.

Specifications confirmed from the manufacturer's datasheet
The Huawei Smart Dongle-4G (SDongleB-06) is the cellular communication module for Huawei SUN2000 inverters. It is inserted into the inverter's USB port, without additional cables, and ensures data transmission to the FusionSolar Smart PVMS platform or to a third-party monitoring system, where there is no fixed internet connection. A single dongle can serve up to 10 devices, respectively up to 10 inverters connected in cascade on the RS485 bus.
The module uses a Mini-SIM card (15 x 25 mm). The European variant covers LTE-FDD B1/B3/B7/B8/B20/B28, LTE-TDD B38/B40/B41 and GSM 850/900/1800/1900 MHz. Besides the cellular link, the dongle provides a WLAN access point (AP mode) used by the installer for local commissioning and for configuration from the FusionSolar app on the phone.
The housing has dimensions of 162 x 48 x 28 mm, an IP65 protection rating and a status LED. The typical power drawn is 3.5 W. The operating range is -30 °C ... +65 °C, with humidity 5–95% RH, storage temperature -40 °C ... +70 °C and a maximum operating altitude of 4000 m. The product has CE, RCM and TELEC certifications.
The meter that tells the Huawei inverter how much the building consumes, so that it does not send current into the grid. Three-phase, up to 250 A per phase, through the included current transformers.
The single-phase meter that measures at the connection point what comes in and what goes out, so that the Huawei inverter can limit the injection into the grid. Direct connection up to 100 A, consumption below 1 W.
It shows in real time how much energy enters and leaves the house, so that the installation can regulate itself. Indirect measurement with 3 clamps of 100 A, accuracy ±1%, DIN rail mounting.
See exactly how much energy comes into the house and how much goes out to the grid: a single-phase panel meter, as wide as two fuses, measuring directly up to 100 A and sending the data over Modbus.
