GoodWe – Ezlogger Pro Remote Monitoring Device – 10-GOO-0800

The EzLogger Pro is a dedicated monitoring accessory developed in-house by GOODWE, designed for use in conjunction with GOODWE solar inverters.It reads and records key operational data from your PV (photovoltaic) system and transmits that data continuously to the GOODWE cloud portal for monitoring, analysis and reporting.In short: it enables you to keep track of performance, diagnose issues, control multiple inverters and maintain visibility regardless of location.

Features & Benefits

• Data acquisition & logging: It aggregates data from connected inverters, environmental monitors or meters via RS485, and stores it locally for upload.
• Remote monitoring & portal integration: The data is uploaded to GOODWE’s monitoring portal (SEMS or other platform) where users can view performance, trends, alerts and historical data.
• Multiple communication modes: Supports wired Ethernet, RS485, and optionally WiFi or GPRS, offering flexibility depending on site connectivity.
• Large system support: One unit supports up to 60 inverters, making it suitable for medium-sized commercial or distributed installations rather than only small residential ones.
• Long-distance RS485 support: RS485 wiring can reach ~1,000 m, making it suitable for installations with widely spaced inverters.
• Secure, reliable data transmission: Includes features like data breakpoint resume (i.e., if connection is lost, data is cached and then resumed) and encrypted transmission process.
• Flexible installation methods: Supports wall-mounting, rail mounting, table placement.
• LED indicators and commissioning software: Provides visual status feedback and a PC software (ProMate) for setup or configuration, e.g., static/DHCP IP switching, inverter quantity settings.

Use Cases

• Commercial rooftop or ground-mounted PV systems: A business in Tanzania with multiple inverters (say 5–20) can centralize monitoring via one logger, making it easier to oversee production, spot underperformance, and reduce downtime.
• Distributed sites or remote installations: For installations in remote or rural Tanzanian locations with limited on-site staffing, EzLogger Pro enables remote monitoring, allowing technicians to see system metrics without frequent physical visits.
• Solar fleet management: For solar installers or asset-managers operating multiple sites, the device supports integration into a broader monitoring platform, enabling trend analysis across sites.
• Energy-yield optimisation & maintenance: By continuously logging generation data, system owners or service providers can identify when an inverter is under-producing, investigate potential shading or soiling, and schedule maintenance batches proactively.
• Compliance and reporting: In markets where regulatory or feed-in-tariff monitoring requires system performance reporting, the EzLogger Pro provides the data backbone for accurate reporting and audit trails.

Value Propositions

• Improving system visibility and performance: In Tanzania, where solar installations may face challenges like grid instability, shading, dust/soiling, or limited technical oversight, having continuous monitoring significantly improves uptime and yield. The EzLogger Pro offers a robust way to gather that data.
• Scalability for growing solar portfolios: As solar uptake grows in Tanzania—commercial rooftops, off-grid or grid-connected systems—the ability to monitor up to 60 inverters from one device offers cost-effective scaling rather than deploying one logger per inverter.
• Connectivity flexibility: Given variable internet infrastructure in Tanzania, the flexibility of Ethernet, RS485 wiring for long runs, WiFi or GPRS (optional) helps address sites where connectivity may be intermittent or non-standard.
• Reduced maintenance costs: Remote monitoring means fewer site visits, quicker fault detection, and better preventive maintenance—especially important in areas with high travel/transport cost or remote installations.
• Global brand backed solution: GOODWE is a recognized global brand with experience in inverter and monitoring systems. That gives confidence in reliability, service and spare-part availability.

• Suitable for commercial/industrial (C&I) installations: Although residential systems may suffice with simpler monitoring, the EzLogger Pro is well-suited to C&I or multi-inverter installations which are increasingly relevant in Tanzania (e.g., offices, warehouses, agricultural operations, mini-grid).
• Data-driven asset management: For Tanzanian investors or EPC firms, asset performance matters. With the logger, they can report real yield to financiers or potential buyers, optimize ROI, and justify maintenance budgets.
• Compliance & grid-integration readiness: With increasing regulation of feed-in, net-metering or grid-export in Tanzania, being able to show accurate logs helps with compliance and may anticipate future grid-management requirements (e.g., reactive power, export limits).

Local Market Positioning in Tanzania

• Installation environment: Given that the unit is rated IP20 (i.e., not weatherproof), it must be installed indoors or in an adequately protected enclosure. In Tanzania’s climate (heat, dust, humidity) this means ensuring a suitably ventilated, shaded indoor mounting for durability.
• Internet/network connectivity: The monitoring capability depends on internet or network connection. In some Tanzanian sites, connectivity may be limited or unstable; therefore, plan for reliable router, data SIM (if using GPRS/WiFi) or offline caching until connectivity restores.
• Spare/maintenance support: Ensure local supply chain or access to GOODWE service/support in East Africa, to handle firmware updates, configuration, and potential hardware issues.
• Training and commissioning: Proper setup (e.g., configuring RS485 wiring, IP settings, device quantity) requires competent installers. Providing training to local technicians will ensure the full benefit of the logger is realized.
• Cost-benefit for small systems: For very small PV systems (single inverter, <5 kW) the cost of the logger and its installation may not justify the benefit compared to simpler monitoring options. It is most cost-effective when multiple inverters or multiple sites are involved.
• Connectivity to non-GOODWE equipment: The logger is designed primarily for GOODWE inverters and ecosystem. If a site uses inverters from other brands, compatibility should be verified.
