Smart Solar Water Heating System

Convert your existing geyser to run on solar power with the Apollo NeoPV Mppt system.

A smart solar water heating solution that maximizes energy efficiency through Maximum Power Point Tracking (MPPT) technology, converting sunlight directly into hot water while providing real-time monitoring capabilities.

It performs the following functions:

  • Converts direct current (DC) from solar panels into alternating current (AC) suitable for standard electric heaters.
  • Transfers solar energy to the heating element as efficiently as possible.
  • Automatically switches between solar and grid electricity when solar power is insufficient.
  • Smart Monitoring Option (mobile app) for live tracking of performance.

Live Monitoring

  • Alerts for low temp or faults
  • Energy used today (kWh)
  • Heating time duration
  • View from phone or PC
  • Water temperature
  • Solar power input

How it operates

  1. Sunlight hits the solar panels
  2. MPPT converts output to maximize power
  3. Energy goes to heat the geyser
  4. Sensors measure temperature & energy
  5. ESP32 sends data to the cloud
  6. User views live data on dashboard
