    PowMr 50A MPPT Solar & Generator DC Charge Controller MD1250N05

    Product Overview:

    MD Series DC/DC MPPT solar charge controller is based on multi-phase synchronous rectifier technology and advanced MPPT control algorithm, adopting an all-digital intelligent design, which has fast response speed, high reliability, and high industrialized standard. Polyphase synchronous rectifier technology can ensure high conversion efficiency under any charging power, and greatly improve the energy utilization of the system; the industry-leading PowerCatcher MPPT technology realizes the maximum energy tracking of solar panels so that it can quickly and accurately track the maximum power point of solar panels in any environment and obtain the maximum energy of solar panels in real-time. 

    This Product is a DC/DC intelligent charger for a vehicle or ship system. Applied in the dual-battery system, the system integrates the respective merits of the generator's power generation and photovoltaic power generation, and a variety of charging methods are ingeniously designed and combined to effectively ensure that the power of the dual-battery system is sufficient all the time. Solar energy and generator can charge the backup battery simultaneously and can charge the backup battery independently. In addition, solar energy can charge the starting battery under specific conditions.

    Product Features:

    • PowerCatcher MPPT technology is still available for tracking the maximum power point of solar cells in a complex environment; and compared with conventional MPPT technology, PowerCatcher has a faster response speed and higher tracking efficiency, which can reach 99.9%.
    • The design of the polyphase synchronous rectifier Buck-Boost circuit makes it have high DC/DC conversion efficiency of up to 98% in both high and low power ranges
    • The backup battery supports a wide variety of batteries such as sealed, colloidal, open-type, lithium batteries, and custom batteries.
    • Support a wide variety of generators such as intelligent generators and conventional generators, and automatically identify generator types through ignition signals.
    • With a variety of charging modes, such as photovoltaic charging backup battery alone, generator charging backup battery alone, photovoltaic and generator's charging the backup battery at the same time, photovoltaic charging startup battery, and soon.
    • The function of line loss compensation of backup battery charging voltage, which makes the battery charging voltage control more accurate.
    • With a backup battery temperature sampling function, a lead-acid battery supports temperature compensation and effectively prolongs battery life.
    • With automatic derating function for high-temperature charging.
    • TTL communication can provide technical support for communication protocol to facilitate
    • users' secondary development and application.
    • Support external remote switch to control charging. 
    • Parameters can be monitored and set through mobile apps and PC monitoring and setting software.
    • A high-quality aluminum radiator and high-temperature derating processing can ensure reliable 
    • and efficient operation in each work environment.
