60A Waterproof MPPT Solar Charge Controller 12V 24V 48V With PC Monitoring
Features of SR-MT2410
1. Adopting double crest or multi crest tracing technique,used for the condition when a part of solar panel is under shadow or parts of panel isdammage
2. Built-in maximum power point tracking algorithm which could promote the energy utilization efficiency of pv system.The charging efficiency is 15%~20% higher than PWM mode
3. It can find out the best working point of I-V curve within 1 minuite,the MPPT efficiency could reach to 99.9%.
4. Adopting advanced digital power supply techniques which makes the energy conversion efficiency reach up to 97%
5. Four charging stages:MPPT-equalizing charge-boosting charge-floating charge
6. With current-limiting charging mode.When the power of solar panel is oversized,the controller will lower charging power automatically,which enable the system to work under the rated charging current
7. Have the fault code indication,it helps user confirm the rated charging current.
8. Various load control methods.could recognize day and night qutomatically.
9. Various system protection functions.including over-charge,over-discharge,over-dischage,over-load,over-heat,battery-reverse connection and short-circuit protection eyc.
Installation and use instruction of SR-MT2410
1. Fix the controller: Fix the controller onto the surface of the specific place. Keep a certain distance between the controller and fitting surface to assure heat dissipation
2. Wire preparation: Adopt the wire matching the current,plan the length of wire, strip 5mm insulation of one side of the controller terminal and try to decrease the length of the connected wire so that a reduction in electrical loss.
3. Connect to the battery: connect the battery wire to the controller firstly, Pay attention to the “+” and “–”, in case of reverse connection. If connected well, the indicator light will be on. Otherwise, please check the connection. If reverse connection, controller will not working but not damage the controller.
4. Connect to the solar panel: Pay attention to the “+” and “–”, not reverse connect. If ample sunshine, controller will show charging mode. Or should check the connection is right or wrong. If solar panel under the sunshine will produce voltage immediately. If use 24V or more than 24V system, the solar panel voltage will exceed to body safety voltage, when use please prevent you self from electric shock.
5. Connect Load:Connected the load to controller,make sure the current cannot over the rated current, and notice the positive and negative electrode. Prevent the system from reverse connect.

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.
