Produktbeschreibung

20A PWM Solar charging controller: automatic detection of the 12 V 24 V system, maximum PV input voltage 50V volts, max. Input power: 260W(12V)-520W(24V); built-in dual USB output 5V/2.5A (max), charging for your mobile phone, tablet, PCs. FULLY 3-STAGE PWM TECHNOLOGY The controller is furnished with advanced and intelligent PWM technology, ensuring high charging efficiency. Through three charging modes (Bulk, Boost, Float), it enables fast, efficient, and safe battery charging, effectively prolonging the battery's lifespan. Moreover, it combines solar light control and time control, allowing for the free adjustment of the load activation duration. This regulator is ONLY suitable for various Lead-acid batteries (including open, sealed, colloid, etc.) Please DO NOT charge to lithium or nickel-metal hydride batteries, etc. Auto-recognizing battery voltage function can protect the battery from misuse and battery control the charging process. Make sure your battery has enough voltage for the controller to recognize the battery type before first installation. Large-screen LCD display,charging and discharging current display,cumulative power generation and discharge power query,temperature display,light control+delay cantrol；adjustable charge and discharge parameters,with power-off memory and other functions. Comprehensive protection function: Build-in short-circuit protection,open-circuit protection,reverse protection,over-load protection，Reverse current protection,low heat production.This solar charge controller will help you improve the system efficiency and prolong the battery life. But still note to install the controller on a flat, well-ventilated surface.
