MPPT solar controller is designed for solar off-grid system, solar power station 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:
1. 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.
2. Increase the charging strategy (first constant current, then constant pressure, the last float), protect the battery and extend its service life.
3. All-digital intelligent control, with remote control.
4. Standard MODBUS communication protocol to facilitate background detection.
5. With overcharge, overload, short circuit and other sound protection, so that the machine is running more reliable.
6. Wide input voltage range, to solve the problem of components should not be matched, selection more convenient.
7. With lightning protection, solar anti-reverse charge, battery reverse, open circuit protection.
8. Small size, light weight, rack design.
9. Small power and DC power distribution cabinet group screen, high power can be more than a parallel group counters, easy maintenance.
10. Single maximum 100A, can be expanded according to demand.
11. Touch screen display, beautiful atmosphere.
