GoodWe – 4G Module Kit – 10-GOO-0801

The GoodWe 4G Module Kit is a compact, plug-and-play communication accessory designed for solar inverter systems that enables 4G cellular connectivity in places where Wi-Fi or wired networking may be unreliable or unavailable. It allows the connected inverter (and thereby the monitoring system) to report operational data via mobile networks. With a rugged IP65 rated enclosure and low self-consumption, it suits outdoor or remote locations. According to GoodWe, “the 4G Module is easy to install with a plug & play design and can support several carriers worldwide. The 4G Module offers customers convenience and reliability, especially in remote areas without access to Wi-Fi.

Features & Benefits

• Plug-and-Play Installation: The unit is designed for quick connection (via USB or compatible interface) to a GoodWe inverter or monitoring interface, requiring minimal setup.
• Carrier Flexibility: Supports multiple cellular operators globally (subject to local frequency band compatibility and SIM-card provisioning). This enables remote monitoring even when Wi-Fi is unavailable.
• Outdoor-Ready Design: IP65 rating ensures resistance to dust ingress and water jets—this suits installations in exposed environments, e.g., rooftop or outdoor enclosures.
• Low Power Draw: With consumption under 4 W, it imposes minimal overhead on the system.
• Wide Operating Temperature: Can function reliably in harsh climates (from –30 °C cold to +60 °C hot), making it suitable for diverse environments.
• Compact Form-Factor: Small size facilitates installation in tight inverter compartments or enclosure spaces.
• Compatible with Monitoring Systems: Works in tandem with GoodWe’s monitoring platforms (for example, SEMS portal) enabling remote performance data, alerts, diagnostics.

Use Cases

• Remote Solar Installations: In Tanzania or other areas with sparse or unreliable Wi-Fi/internet networks, this module enables solar systems to report performance data via the cellular network.
• Off-Grid or Hybrid Systems: Even in grid-tied systems where Wi-Fi is not feasible (e.g., solar farms, large rooftop arrays), the 4G Module ensures continuous connectivity for monitoring.
• Commercial & Residential Solar Projects: From a single-phase rooftop system to small commercial installs, the module gives a simple way to add cellular connectivity.
• System Maintenance & Monitoring: Installers and system owners can receive remote alerts, fault notifications and performance reports without site visits.
• Hard-to-Reach Installations: Locations such as rural homes, lodges, remote camps, off-grid resorts where network connectivity infrastructure is weak benefit significantly.

Value Propositions

• Bridging Connectivity Gaps: In many parts of Tanzania, stable Wi-Fi/internet access may not be guaranteed, particularly in rural or semi-urban solar installations. Using 4G connectivity via this module ensures the solar system remains connected and monitored.
• Resilience in Harsh Conditions: With its IP65 rating and wide temperature tolerance, the module is suitable for Tanzania’s varied climate (hot, dusty, sometimes humid).
• Ease of Installation: For local solar installers, the plug-and-play nature reduces commissioning time and complexity—important in markets where specialist labour may be limited.
• Support for Multiple Carriers: Tanzania has various mobile network operators; the module’s worldwide carrier support means that local SIM cards can be used, enabling local connectivity plans rather than only Wi-Fi.
• Cost-Effective Monitoring Enhancement: By enabling cellular connectivity without full Wi-Fi infrastructure, it helps system owners and EPCs (engineering, procurement & construction firms) enhance monitoring and service capability at a modest incremental cost.
• Added Value for System Owners: For homeowners, commercial installations (shops, lodges, farms) or small-scale developers, the ability to monitor energy production, system health and get alerts adds significant peace of mind and operational visibility.
• Future-Proofing: As Tanzania’s networks mature, the module ensures the system remains connected and compatible with newer monitoring standards.

Local Market Positioning in Tanzania

• Check local network bands: Although the module supports many global LTE/WCDMA bands, ensure the specific variant (e.g., 4G Kit-EC/AU/US) is compatible with the carrier bands used by Tanzanian mobile operators (such as Vodacom, Airtel, Tigo) before order.
• SIM card & data plan: Local installation will need a SIM card with an appropriate data plan (likely low-data usage for telemetry). Ensure local EPCs/owners budget for this.
• Installation environment: While IP65 rated, ensure it is mounted in a location with mobile signal strength—rooftop or near inverter location may need checking.
• Retrofitting older systems: If installing in existing GoodWe inverter installations, verify compatibility with the firmware version and monitoring platform.
• Supply chain & warranty: Confirm local distributor support, warranty service and spare availability in Tanzania or East Africa region.
• Promote monitoring value: Emphasise to customers that connectivity allows real-time insights, helps detect faults early, ensures optimal performance and maintenance—thereby long-term value.
