HQRP Solar Charge Controllers are high quality, efficient and reliable Solar Power Regulators. They are perfect for rural electrification system. They offer a lot of possibilities and benefits. Regulations point: 14.4 Volts; Low voltage Disconnect: 11.1V Volts; Low voltage Reconnect: 13.1 Volts; Microcontroller digital accuracy; Type of Charging: Series PWM & stat of charge(SOC); 4 Stages: equalization, PWM, Boost and Float, temperature compensated charging; Electronic protections: Short circuit and over current-solar and load; Reverse current at night; Limits high voltage to protect loads; Lighting protection; Tropicalization: Conformal coated printed circuit board; Self-consumption: 6mA maximum. Solar Controller supports up to 300W of 12V Solar panels and up to 600W of 24V Solar panels. For 12V solar panels, please, use battery and load for 12V solar systems (For 24V solar panels, please, use battery and load for 24V solar systems). HQRP UV Chain / UV Radiation Tester: To know the Solar UV Index, it is enough to compare the colorchange with the 4 standard colors around. Very light purple: low intensity, UV index 1-2. Sun-protection not necessary. Light purple: medium intensity, UV index 3-5. Sun-protection is recommended. Purple: strong intensity, UV index 6-7. Sun-protection is necessary. Dark purple: very strong intensity, UV index 8-11. This tester shows you the level of UV radiation and helps you protect your eyes and skin from negative sunlight effect, but this meter doesn't show sunlight intensity for solar panels.
