Transparent Energy You Can Trust

WattConduit is an intelligent, modular solar energy conduction and battery storage platform designed to capture, regulate, and securely deliver electricity generated by photovoltaic panels into battery storage systems. By combining solar input management, maximum power point tracking (MPPT), advanced DC-to-DC power conversion, and intelligent charging management, WattConduit transforms variable solar electricity into controlled, battery-compatible energy. Its architecture is designed to support different solar configurations, battery chemistries, and storage capacities, making it adaptable to residential solar installations, off-grid systems, homesteads, and distributed energy infrastructure.

WattConduit features an extensive collection of intelligent energy management and battery protection capabilities, including real-time voltage and current monitoring, chemistry-specific charging profiles, battery temperature monitoring, state of charge estimation, charging cycle tracking, and automated charging regulation. Its electrical protection systems incorporate overvoltage, overcurrent, reverse polarity, short-circuit, and thermal protection, with independent hardware safeguards designed to maintain safe operating conditions even if the software encounters a failure. Advanced MPPT algorithms continuously optimize solar energy capture, while intelligent power conversion regulates electrical output to meet the requirements of connected battery storage systems.

The platform also incorporates comprehensive energy monitoring, diagnostics, and visualization capabilities through a local-first dashboard. Users can monitor solar production, charging activity, battery status, conversion efficiency, accumulated watt-hours, electrical losses, and system health. Connectivity options include MQTT, REST APIs, USB, serial communication, CAN bus, Modbus, and integrations with compatible battery management systems and home energy platforms. Optional extensions introduce predictive solar intelligence, AI-assisted energy optimization, advanced battery analytics, remote monitoring, automated reporting, and microgrid coordination, allowing users to expand functionality without compromising the independence of the core system.

WattConduit’s modular hardware and firmware architecture makes it possible to build, customize, repair, and expand individual system components rather than depend on an entirely proprietary energy management solution. Dedicated modules for solar input protection, MPPT, power conversion, battery charging, electrical safety, telemetry, system control, and diagnostics work together through documented interfaces. With an emphasis on transparent engineering, independently verifiable safety mechanisms, local operation, component-level repairability, and user-controlled energy data, WattConduit aims to make reliable solar-to-battery storage technology more accessible to individuals, communities, researchers, and independent energy developers.
