MPPT Solar Charge Controller NMH-50A high-efficiency
The NMH-50A MPPT Solar Charge Controller is a high-efficiency, multi-voltage solar energy management solution designed to optimize power harvesting and battery performance across diverse applications. Compatible with 12V/24V/36V/48V systems, it automatically adapts to voltage configurations and supports parallel setups for scalable energy storage. Featuring advanced MPPT technology with >99.5% tracking efficiency and 97.5% peak conversion efficiency, it delivers up to 30% more solar energy than traditional PWM controllers, even under variable input conditions .
Product Introduction
The controller supports Gel, AGM, Flooded, Sealed lead-acid, and Lithium batteries, utilizing a 4-stage charging algorithm (Bulk, Absorption, Float, Equalize) with customizable voltage settings to extend battery life. Real-time monitoring is enabled via an LCD+LED display and optional RS485/Ethernet/RS232 communication, allowing users to track solar harvest status remotely.
Built for reliability, it integrates dual-fan cooling for quiet operation, comprehensive protections (short-circuit, reverse polarity, overcharge), and robust IP20-rated housing. With a wide operating temperature range and temperature compensation, it ensures stable performance in harsh environments. Ideal for off-grid and hybrid systems, its compact design and 63A load capacity make it a versatile, user-friendly choice for maximizing solar energy utilization.
● At least 30% higher solar harvest for power compare with PWM controller.
● Wide range Solar PV voltage input 18V～150Vdc.
● LCD+LED display, you can see each second solar harvest status.
