Solar Charge Controller PWM step-controller manufacturers

Off-grid controller temperature compensation function off-grid solar power system is normally provided by solar panels, PV combiner box, solar charge controller, battery, off-grid inverter and other components. Sunlight through solar panels is converted to electrical energy, through the controller to charge the battery, and then through the off-grid inverter direct current into alternating current batteries for electric devices. Traffic areas, such as beacon lights, traffic / railway signal lights, traffic warning / marker lights, street lamps, high-altitude obstacle light, highway / railway wireless telephone booths, etc. unattended Road class for power. For communication / communication field: Solar unattended microwave relay stations, cable maintenance stations. Lighting Power: as garden lights, street lamps. PV power plant: independent photovoltaic power plants, scenery (CHAI) complementary power plants, various large parking lot charging stations, small home power plants, factories and other small-scale power stations. Solar Architecture: solar power generation and construction materials combined make future large-scale construction to achieve self-sufficiency in electricity is a major future development direction. For remote areas without electricity, such as highland, island, pastoral, border posts and other military and civilian life electricity. LCD display, easy operation, good operating performance, and can automatically control the solar cells connected and disconnected the battery voltage changes. The controller makes full use of solar resources and keep the battery safe and reliable. ? In order to meet the different needs of photovoltaic power plants, there are 24V, 48V, 96V, 120V, 192V, 220V, 240V, 360V, 480V and other voltage models, depending on the battery voltage off-grid PV power plant system project. Using PWM step-limiting step by step method of charging, based on trends in the auto battery terminal voltage control multiple solar battery phalanx turn on or off. An array of multi-channel multi-charging control control loop, each equipped with a circuit breaker switch, independent, easy to operate, safe and reliable. Has a battery overcharge, short circuit electronics, anti-reverse protection to prevent battery at night to charge and discharge the anti-solar panels and other automatic protection. ? Large-screen LCD display. Solar panels, batteries, controller working status (solar panel voltage, current, power, display, battery voltage, charge current, charge power display). ? Power switch driver circuit and the sampling circuit is completely electrically isolated optocoupler isolation control signal transmission, so that with a very high anti-interference ability and stability. ?? The internal controller has mine. The solar panels fleeing transient over voltage limit within the device or system can withstand voltage range, or the powerful lightning current into the ground, to protect equipment from lightning strikes and damage. ? All control all adopt industrial-grade chips, to the cold, hot, humid environment running. ? Temperature compensation. Depending on the temperature compensation can be affected by temperature for various types of batteries. ? A variety of communication RS-232, RS-485, USB, GPRS, Ethernet, etc. to maximize meet the needs of different occasions.
