Product Description

NOVA NEW DC/DC&MPPT Solar Charge Controller 30A 50A For RV Boat, universal for PV and generator charging battery

-- Applied to dual battery system, Lithium lead-acid battery used at the same time.

-- The PV/generator charges the backup battery separately.

-- The PV and generator charge the backup battery simultaneously.
-- PV to charge the starter battery.
-- Supports multiple generator types such as smart generators (Euro VI) and traditional generators.
-- Loss compensation/temperature compensation for backup battery charging voltage line.
-- High temperature charging automatic derating / low temperature prohibit charging.

-- 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 faster response speed and higher tracking efficiency, which can reach 99.9%.

-- The design of polyphase synchronous rectifier Buck-Boost circuit makes it have high DC/DC conversion efficiency 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 battery and custom battery.

-- Support a wide variety of generators such as intelligent generator and conventional generator, 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 backup battery at the same time, photovoltaic charging startup battery and soon.


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. Poly phase synchronous rectifier technology can ensure high conversion efficiency under any charging power, and greatly improve the energy utilization of the system; the industry-leading Power Catcher 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 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.
