Overview

Solar power represents a multi-decade capital investment — one that only delivers its full financial return when every panel, string, and inverter performs exactly as designed. Without continuous, data-driven monitoring, inverter faults, string failures, soiling losses, and shading anomalies go undetected for days or weeks, silently eroding your energy yield and ROI. Our Solar Power Remote Monitoring solution is built on the Teltonika TRB140 industrial LTE IoT gateway — a field-proven, Modbus-native device trusted across energy and utility deployments worldwide. TRB140 gateways connect directly to your inverters and meters via Modbus TCP, reading panel output, string currents, DC voltage, AC export, fault codes, and alarm states in real time. Multiple inverters and panels are networked via Teltonika TSW210 industrial Ethernet switches, reducing gateway count and making the architecture cost-efficient at any scale — from a single commercial rooftop to a multi-site utility portfolio. All telemetry is transmitted over 4G LTE to Teltonika's RMS 5.0 platform — the industry's first true fusion of IoT data collection and remote device management — giving your operations team a live, unified view of every installation from any browser or mobile device, anywhere in the world, installed and supported end-to-end by our Nairobi-based team.

How It Works

From installation to insight — step by step

01

IoT Gateway & Network Installation

Teltonika TRB140 LTE IoT gateways are installed at each inverter cluster. Teltonika TSW210 industrial Ethernet switches network multiple panels and inverters to a single gateway — minimising hardware cost while maintaining full data granularity across every string.

02

Modbus TCP Data Acquisition

The TRB140 polls each inverter and smart meter via Modbus TCP at configurable intervals, extracting DC string voltages and currents, AC output power, total energy generation, fault registers, and device alarm states — all without proprietary vendor lock-in.

03

4G LTE Transmission to RMS & Cloud

Collected Modbus data is packaged and transmitted over 4G LTE via MQTT to Teltonika RMS 5.0 or directly to your solar ERP or SCADA platform. Onboard data buffering ensures zero data loss during intermittent connectivity, preserving a complete, uninterrupted performance record.

04

Live Dashboard, Alerts & Remote Management

Your operations team monitors live generation, string health, fault codes, and energy export on the RMS 5.0 dashboard. Custom alerts fire instantly via SMS or email on any fault condition. RMS Connect enables full remote access to gateway configuration — eliminating truck rolls for routine diagnostics.

Key Features

Everything you need in one solution

Live Generation & String Monitoring

Real-time visibility into DC string currents and voltages, AC output power, and total energy export per inverter — updated continuously via Modbus TCP polling, displayed on the RMS 5.0 live dashboard.

Modbus TCP & RTU Protocol Support

Native Modbus TCP client built into the TRB140 gateway enables direct, standards-based communication with all major inverter brands — SMA, Huawei, Fronius, SolarEdge, Growatt, and more — without proprietary middleware.

RMS 5.0 Unified IoT Platform

Teltonika RMS 5.0 combines real-time sensor data collection with full remote device management in a single platform — the first of its kind in the industry. Monitor data, configure gateways, and push firmware updates across your entire solar portfolio from one console.

Real-Time Fault & Performance Alerts

Custom alert rules trigger instant SMS and email notifications on inverter fault codes, string current imbalances, output deviations from expected baseline, communication loss, or gateway disconnection — enabling same-day fault response.

Secure Encrypted Remote Access

RMS Connect establishes encrypted SSH, HTTP, and VPN tunnels directly to any gateway or inverter interface — enabling remote diagnostics, parameter adjustments, and firmware updates without requiring a public IP address or firewall reconfiguration.

Performance Analytics & PR Calculation

Track daily, monthly, and annual energy generation per inverter and per site. Compare actual output against irradiance-adjusted expected generation to calculate Performance Ratio — the definitive metric for solar plant health and O&M accountability.

Scalable Multi-Site Architecture

A single RMS 5.0 account manages dozens of sites simultaneously — residential rooftops, commercial plants, and utility-scale farms — all visible on one network map with per-site drill-down. Scale from one gateway to hundreds without additional infrastructure.

Automated Energy & Compliance Reports

Scheduled daily and monthly reports deliver energy production totals, Performance Ratio trends, fault event logs, and uptime statistics — formatted for board reporting, offtake agreement compliance, utility grid submissions, and carbon credit documentation.
