⭐⭐⭐MPPT Solar Charge Controller 200W/400W Step-up/down Input 17V-55V Output 10V-85V Real-time Tracking Adjustable Recharging

Step-upFeatures:With the LED display for you to see the input and output voltage and current, you can check it easily.The output voltage can be adjusted between 24~85V.Overheating protections function: When the internal ambient temperature exceeds 100°C, it will reduce the output power. If the internal ambient temperature continues to rise to 110°C, it will automatically turn off the output. When the internal ambient temperature is lower than 85°C, it will automatically resume work.Short circuit protections function: When an accidental short circuit occurs in the output of the controller, the controller automatically turns off the output, and automatically returns to normal after the short circuit is eliminated.Input undervoltage protections function: When the input direct current voltage of the controller is lower than 15V, it will shut down protectively and automatically resume work after the input voltage is normal.It has a high efficiency real-time tracking function and a high-efficiency synchronous rectification solution. It also has the IP66 waterproof and dustproof grade.Specifications:Material: aluminumPhotovoltaic input power:400WSuitable photovoltaic panel:Open circuit voltage: 18~55VMaximum power voltage: 17~55VPhotovoltaic input starting voltage: 18~55VPhotovoltaic input tracking voltage: 17V~55Voutput to the battery voltage: 24~85V (adjustable)No-load loss: 0.35WVoltage adjustment rate: 1%Load adjustment rate: 1%Efficiency: 99%Working temperature: -40℃~65℃Install line length: 50mmItem size: 120 * 80 * 40mm / 4.7 * 3.1 * 1.6inItem weight: 450g / 1.0lbPackage size: 160 * 90 * 50mm / 6.3 * 3.5 * 2.0inPackage weight: 500g / 1.1lbPacking list:1 * 200W/300W/400W Battery Recharging ControllerStep-downThis MPPT step-down real-time tracking solar battery recharging controller with the LED display, and the output voltage can be adjusted, and suitable for le-ad-acid, lithium-ion and other batteries in line with 10~30V recharging voltage. Come on and try it, it will not let you down.Features:With the LED display to show the input and output current and voltage, you can see the data more clearly.The output voltage can be adjust between 10~30V, you can choose the suitable for your needs.Suitabe for the le-ad-acid, lithium-ion and other batteries in line with 10~30V recharging voltage.Efficient MPPT real-time tracking function, give you a better using experience.Overheat pro-tection function: When the internal ambient temperature of the MPPT controller exceeds 100℃, the output power of the MPPT controller will be reduced. If the internal ambient temperature continues to rise to 110℃, the output of the MPPT controller will be automatically turned off. When the internal ambient temperature of the MPPT controller falls below 85℃, the MPPT controller will automatically resume operation.Short circuit pro-tection function: when the MPPT controller output comes unexpected short circuit, MPPT controller will automatically close the output, the short circuit will automatically return to normal after elimination.Input under-voltage pro-tection: when the MPPT controller input direct current voltage is lower than 15V, MPPT will protective shutdown, the input voltage is normal automatically resume work.Specifications:Material: aluminumSuitable for: the battery of recharging voltage between 10~30VSuitable solar panel:The open circuit voltage: 18V~55VMaximum power voltage: 17V~55VOutput power: 400WPhotovoltaic input starting voltage: 18V~55VPhotovoltaic input tracking voltage: 17V~55VOutput to the battery voltage: 10~30V (adjustable)Output to the battery current: Max.25ANo-load loss: 0.35wThe pi-tch of the installation: 110mm * 70mmInstallation hole diameter: 5mmVoltage adjustment rate: 1%Load adjustment rate: 1%MPPT efficiency: 99%Working temperature: -40℃~65℃Install line length: 50mmItem size: 130 * 80 * 40mm / 5.1 * 3.1 * 1.6inItem weight: 450g / 1.0lbPackage size: 160 * 90 * 50mm / 6.3 * 3.5 * 2.0inPackage weight: 500g / 1.1lbPacking list:1 * 200W/300w/400W Solar Recharge Controller
