  • 【RV dedicated MPPT controller】:The MPPT Solar Charge Controller and LCD Screen can be set separately, giving you a better choice of monitoring position. The MPPT Controller has the TVS lightning protection. The external LCD screen can be connected for viewing of equipment operating data and status, and modification of controller parameters is supported.
  • 【Charge Smarter】:Due to advanced digital power technology, the circuit energy conversion efficiency 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℃~+60℃. 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.
  • 【Low loss】: The charge controller can further improve the MPPT control algorithm to minimize the maximum power point loss rate and loss time, and in any case, can quickly track the maximum power point of the photovoltaic array and obtain it from it The energy solar cell module gets the most energy.
  • 【High energy efficiency】:the MPPT control can increase the ratio of energy utilization in the solar system by 10%-30% compared with a PWM charging method. 
  • 【Stability and reliability】:The limitation function of the charging power and current and reducing charging power function automatically improves the stability which works even connecting oversize PV modules and at high temperatures.
