MPPT type Solar Controller
This product is designed for solar off-grid system (independent system), solar power plants and other systems. The new generation of MPPT controller selection 16-bit digital signal processing chip. It adopts advanced all-digital intelligent tracking algorithm to obtain the maximum power point of solar modules, and real-time output current, voltage detection, to ensure the normal battery charging and improve the utilization of components. At the same time the system has short-circuit, overload, and a unique battery automatic shutdown, recovery and other full-featured protection measures.
Features
● All-digital intelligent tracking algorithm, the fastest access to solar modules maximum power point, the conversion efficiency up to 95%, high utilization of PV modules.
● Increase the charging strategy (first constant current, then constant pressure, the last float), protect the battery and extend its service life.
● All-digital intelligent control, with remote control.
● Standard MODBUS communication protocol to facilitate background detection.
● With overcharge, overload, short circuit and other sound protection, so that the machine is running more reliable.
● Wide input voltage range, to solve the problem of components should not be matched, selection more convenient.
● With lightning protection, solar anti-reverse charge, battery reverse, open circuit protection.
● Small size, light weight, rack design.
● Small power and DC power distribution cabinet group screen, high power can be more than a parallel group counters, easy maintenance.
● Single maximum 100A, can be expanded according to demand.
● Touch screen display, beautiful atmosphere.
