I will develop solar mppt charger controller prototype for off grid power system

I will develop a custom Solar MPPT Charge Controller Prototype for your off-grid power system. Maximize solar energy harvest with advanced Maximum Power Point Tracking (MPPT) technology, delivering superior efficiency compared to standard PWM controllers.

What You Get:

• High-efficiency synchronous buck converter (95-98% efficiency)
• ESP32/Arduino-based MPPT using Perturb & Observe algorithm
• Supports 12V/24V/48V batteries (Lead-Acid, LiFePO4, GEL)
• PV input up to 100V, scalable current 10-60A
• Voltage/current sensing, full protections (OV/UV, OC, reverse polarity, temp)
• Optional LCD display, WiFi monitoring, MQTT dashboard & data logging
• CC/CV charging stages for optimal battery life

Scalable from small off-grid setups (cabin, RV, boat) to larger systems. Professional, reliable, and cost-effective alternative to commercial units. Open-source friendly with full design files for future scaling or production

Perfect for cabins, RVs, boats, or remote solar setups. Scalable from prototype to production
