RS232 Remote Meter RM 5 MPPT Solar Charge Controller 20A 30A 40A 60A

Remote meter RM-5 for ML series MPPT solar charge controller 20/30/40/60A

Product Overview

The SRNE RM-5 Tracer meter is the remote digital display used for the 20A/30A/40A/60A ML series MPPT Charge Controllers. It is a self-diagnostics meter ideal for monitoring and displaying the current solar system status information and any error indications the system might be experiencing. The information is displayed on a backlit LCD display and is easily navigated using the large buttons on the meter. The MT-5 Tracer meter could also be flush mounted on a wall or flat surface using the mounting frame provided. The RM-5 is supplied with a 1.5 meter long cable and is connected using the RJ12(6-PIN) port.

Electric Parameters

FAQ:
Q: How many charging mode does the controller have?
A: There are two charging modes. There are PWM and MPPT. MPPT is the most advanced. Srne have already developed MTTP charge controller with high performance, reliability, efficiency and fast tracking speed.

Q: What's the difference of the PWM charge controller and MPPT charge controller?
A: 1. MPPT controller uses maximum power tracking technology, compared to the PWM controller, the MPPT can generate more electricity with the same solar panels.
2. MPPT controller has low requirement of solar power system voltage, if the line or component parts damage the voltage, using MPPT controller does not affect the system generating.
3. MPPT controller can detect the temperature of the battery, then adjust the temperature by itself, the solar panel can charge the battery more efficiency.

Q: Why should the controller have temperature compensation function?
A: As temperature rises, electrochemical activity in the battery increases. Similarly, as temperature falls, electrochemical activity decreases. Therefore, as temperature rises, charging voltage should be reduced to prevent overcharge, as temperature falls, charging voltage should be increase to avoid undercharge. In general, to assure optimum service life, use of a temperature compensated charger is recommended.

Q: How does your factory carry out quality control?
A: Quality is our priority. Our QC always attached great importance to quality control from the very beginning to the end of the production. Each product will be fully assembled and carefully tested before packed.
