Production introduction

The DC-50 family of charge controllers is the latest innovation in maximum power point Tracking(MPPT) charge controllers from DUCHY power systems.The MPPT software algorithm is both continuous and active,increasing your photovoltaic array power yield up to 30% compared to non-MPPT controllers.Thanks to active colling and intelligent management colling, charge controllers can operate at their full maximum current rating,100Amps respectively,in ambient temperatures as 50°C.

Included in all of the DC-50 charge controllers are the revolutionary features fist developed by Power,including support for a wide range of nominal battery voltages and the obility to step-down a higher voltage solar array to recharge a lower voltage battery bank.

DC-50 MPPT charge controllers are the only choice when you demand a high performance,efficient and versatile charge controller for your advanced power system.

DC-50 series includes two types of desktop and modular products, desktop-type including narrow range and the wide range, the main difference is the input voltage range. Desktop maximum current of solar charge controller is 100A, mainly for small and medium sized off-grid solar power system. Combined solar charge controller input wide range, single charge current to 100A can be combined for the 800A, and has a power distribution unit and monitoring unit, mainly for medium and large-sized off-grid solar power system.
