Stable Waterproof MPPT Solar Charge Controller MPPT Tracking Technology
Product Overview
Maximum Power Point Tracking (MPPT) is an advanced charging technology that enables thesolar panel to output more power by adjusting the electric module's operating status. Due to the nonlinearity of solar arrays, there exists a maximum energy output point (maximum power point) on their curves. Unable to continuously lock onto this point to charge the battery,
conventional controllers (employing switching and PWM charging technologies) can't get the
most of the power from the solar panel. But a solar charge controller featuring MPPT technology can continuously track arrays' maximum power point so as to get the maximum amount of power to charge the battery.
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.
