SR-RM Series LCD Unit SR-RM-5 is a state-of-the-art advanced MPPT solar controller that excels in optimizing solar energy systems. This unit utilizes advanced dual-peak and multi-peak tracking technology, allowing it to effectively manage solar panels even under challenging conditions, such as partial shading. By intelligently tracking the maximum power point, the controller improves energy efficiency significantly, boasting up to a 99.9% tracking efficiency and enhancing overall energy conversion to 98%.

Features:

◆With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.

◆A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.

◆ A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time

◆ The product boasts an optimum MPPT tracking efficiency of up to 99.9%

◆ Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%

◆ Different charging program options including those for gel batteries, sealed batteries and open batteries, customized ones, etc. are available

◆ The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.

◆ Instantaneous large current startup of capacitive loads is supported

◆ Automatic recognition of battery voltage is supported.

◆ LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.

◆ Historical data storage function is available, and data can be stored for up to a year.

◆ The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.

◆ The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.

Designed with user convenience in mind, the SR-RM-5 features an LCD screen that displays real-time operational data and alerts users to system abnormalities through LED indicators. With historical data storage for up to a year, users can monitor performance over time. The controller supports various charging modes for different battery types, ensuring versatility and adaptability to user needs.
