The PV solar charge controller is a smart device which designed for the large-scale photovoltaic off-grid power generation system. The controller can control multi-line solar arrays matrix and achieve the battery groups charging and discharging functions, in accordance with the trend of the battery terminal voltage automatic control PV arrays turn on or cut away, not only can take full advantage of the valuable resource of solar module, battery pack but also to ensure a safe and reliable work. The controller can control charging and discharging automatically by the advanced algorithm. This would optimize charging and discharging process to improve system performance and increase the battery’s service life. Meanwhile, the controller has multiple self-diagnosis and electronic protection function, such as under-voltage protection, over-voltage protection, thunder stroke protection, etc. All of these will extend the service life of the controller. Products are mainly used independent home PV system, telecommunications base stations, fishermen and herdsmen of electricity, as well as in remote mountainous and border posts PV power supply.
To meet different power stations’need, there are 24V、48V、96V、120V、192V、220V、240V、360V、
492V and other normal series voltage level base on different battery voltage of off-grid PV power station system project.
Digital design, modular structure, stable and reliable.
LCD panel (backlighting) show working parameters and the status.
High efficiency by PWM charging method.
Be able to offer DC power supply (optional).
Anti-reverse connection protection make there is no reversely charging in night. Also with over-charge, limited charging current &voltage protections for battery.
Users can adjust the working parameters, such as over-charge voltage, over-charge recovery voltage, delay time to cut off charging and delay time to recovery charging, etc.
With alarm function in system to tell the abnormal status.
Equipped with data communication function (optional).
Day and night double process mode.
Scientific cooling design which make the PCB board always work under best temperature environment. This will greatly increase the life of the controller.
