Weight: 2.65 lb Item Description ?RV dedicated MPPT controller?: Negative ground designed for RV. Better protection of LCD readings while protecting the controller, and modification of controller parameters is supported. ?Charge Smarter?:Due to an advanced digital power technology,the circuiit energy conversion effciency is as high as 98%.Automatically detects 12V or 24V DC system voltages. Compatible with various Deep Cycle battery options: Sealed, Gel, Flooded, and Lithium. ?Efficient MPPT Weather resistance?:Rated charging current:40A Operating temperature:-35??+45?. It has a big heatsink on the back, but even in 45 degree weather it hasn't become warm, which is a great indicator of its high efficiency. The charger is efficient in charging your battery. It helps that battery can be charged up quickly,even when the weather isn't ideal (ie cloudy rainy days). ?Electronic protection?:Electronic protection against reverse polarity, overcharging, over-discharging, overload, short-circuiting, and reverse current. ?Electrical Parameters?:System voltage:12V/24V Auto Battery voltage:9V?35V Wire specifications:20-6AWG Size:183*127*65mm Max.PV input power:520W/12V 1040W/24V Product Description Solar charge controller your RV, for easier life Based on negative ground design and advanced MPPT control algorithm, designed for RV, with LCD displaying running status. Improving the MPPT control algorithm further, BougeRV charge controller can minimize the maximum power point loss rate and loss time, quickly track the maximum power point of the PV array and obtain the maximum energy from solar modules under any conditions; and can increase the ratio of energy utilization in the solar system by 10%-30% compared with a PWM charging method. The limitation function of the charging power and current and reducing charging power function automatic improve the stability which works even connecting oversize PV modules and in high temperature, and increase the professional protection chip for the communication port, further improving the reliability and meeting the different application requirements. Independent LCD Display Displaying system operating information and error codes. Better protection of LCD readings while protecting the controller, and modification of controller parameters is supported.
