20A PWM Solar Charge Controller 12/24V with USB
1 Year WarrantyUSB 2.0

Intelligent yet lightweight, this solar controller uses Pulse Width Modulation (PWM) to control battery charging. With total autonomy, its set-and-forget operation means you can get maximum charge into your batteries from your solar installation without having to worry about those things. Suitable for solar panels up to 320W, it provides all the important safety features such as overload, short-circuit, over-discharge, and reverse-polarity protection. A handy feature is also the USB port located on the front panel, to provide up to 1.2A charging. Very handy during power outages to keep your phone charged without any additional equipment. Charge modes include bulk, equalise, and float charging, and the unit automatically switches to the best charging mode. Suitable for sealed led acid, as well as Gel/flooded type cells.

Note: Solar panel nominal voltage must match battery voltage - eg. 12V solar panel on a 12V battery system.
