RV Special MPPT Solar Charge Controller 30A 50A Generator Charge Controller Dual Battery PV Generator Intelligent Charger For Vehicle Boat Ship Solar Power System


Product Overview

NVMD Series DC/DC&MPPT solar charging controller is based on multi-phase synchronous rectifier technology and advanced MPPT control algorithm, adopting 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 vehicle or ship system. Applied in the dual-battery system, the system integrates the respective merits of 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 lof the dual-battery system is sufficient al 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.
