OpenEMS - Open Source Energy Management System
time-of-use (tou) tariff based solar and grid energy management platform
Compare Ontario electricity plans (Tiered, TOU, ULO) — editable rates, kWh calculator, Docker + Traefik PWA.
A physics-based EV route planner and energy simulator. Predicts battery drain using topography, weather, and aerodynamics, while optimizing charging costs via Time-of-Day tariffs.
Autonomous Sigen inverter controller for home solar and battery systems. Very lightweight (can run on RPi), making mode decisions every 5 minutes based on solar forecasts and live battery SOC — optimising between, self-consumption, grid export, and overnight TOU charging. Using Irish ESB Solar forecasts but portable to other providers.
Simulate battery energy storage systems for load response, arbitrage, backup, and solar dispatch in your browser.
