Main technical parameters

2.1. Solar Panels

The solar panels are assembled in an array format, primarily using two (or more) small solar panels. They can be connected in parallel or in series, providing either high current or high voltage solar panel networking options.

• Maximum Output Power: 30W x 2 panels
• Open Circuit Voltage: 21.6V (parallel)
• Short Circuit Current: 2 x 1.66A (parallel)

2.2. Lux Meter

• Range: 0-225Lx, 200-2250Lx, 2000-22500Lx, and 20K-225KLx (225000Lx), with automatic range switching.

2.3. The system includes a voltmeter, ammeter, active power meter, reactive power meter, temperature meter, and hygrometer.

• 1 200V DC voltmeter, 1 5A DC ammeter
• 1 500V AC voltmeter, 1 5A AC ammeter
• 1 power meter
• Temperature and hygrometer: Temperature measurement range: -50°C to +70°C, Humidity measurement range: 20% to 90%

2.4. Environmental Monitoring Module Technical Specifications

• Includes a lux meter, thermometer, hygrometer, and a single-chip clock system for time display.

Solar Controller:
