Reproducible off-grid solar streetlight dimming-control framework with battery runtime forecasting and blackout severity metrics.
Two-Pi distributed dry-contact relay controller. Master handles logic, web UI, scheduling, notifications; remote slave drives the relay with an independent failsafe. Generic 2-wire input/output works for generator start/stop, pumps, valves, fans, irrigation, anything switched by a relay.
A complete engineering design of an off-grid solar PV system for a residential load in Al Ain, UAE. The project includes load analysis, PV sizing, inverter and battery selection, and uses real solar radiation data to ensure an efficient, reliable, and optimized system design.
Off-grid 4-channel PWM load controller with regulated 12 V output from any 12–32 V battery. Sunrise/sunset + RTC scheduling, LiFePO₄ battery protection, dimming pots and an OLED. ATtiny3216 firmware + KiCad hardware. No WiFi, no cloud, no app.
Free Windows ECO-WORTHY Bluetooth LiFePO4 battery monitor. Track multiple batteries' SOC in the system tray. No cloud or subscription.
Home Assistant YAML for a zero-export off-grid house: PV surplus heating rods, LiFePO4 voltage floor, per-phase grid emergency heating (3x Voltronic-type inverters, Solar Assistant)
