This series controller is a PWM charge controller with a built-in LCD that adopts the most advanced digital technique. The multiple load control modes enable it can be widely used on solar off-grid systems, traffic signals, solar street lights, etc.
please note: 20A is corresponding to 12V 24V System; 30A 60A 80A iscorresponding to 12V 24V 36V 48V System
Product Features:
System voltage of battery 12V/24V or 12V/24V/36V/48V automatic recognition;
Intelligent 4 stages PWM charging: Bulk, Absorption, Equalize, Float;
LCD display with Back-lighting shows device’s operating data and working condition;
Humanized simple button operation; Adjustable charge-discharge control parameters;
Support more kinds of battery: Lead-acid battery (Sealed, Gel, Flooded) and Lithium battery (LiCoMnNiO2, LiFePO4);
Multiple load control modes: 24Hours Working Control, Light Control, Light and Dual Time Control;
Automatic temperature compensation and accumulated function of charge and discharge KWH;
Double USB output 5V/2A;
Perfect electronic protections.

NOTE for using the Solar charge controller
Equalizing charge will be after every 90 times Floating charge, or one charge in three months;
Default maximum charging current of Lithium battery is 5A, but it can be adjusted by users within the rated current range.
Under the interface of Accumulated KWH, long press button “+” to clear the value;
When no operation 30s, the interface will be back to main interface, and back-light will be turned off.
Never wire your solar panel to controller when controller doesn’t connect battery.

Thought 20A TB was 48V and came 12/24V. When choose before buy never appeared to say anything.

Excellent charge controller, although not MPPT your performance and very good, have other 2 same model working more than 1 year without any problem.

Works well in an rv for 1 380 watt pv cell
Tired of poor quality –
This inexpensive controller fit my needs on a 200 watt solar install. I bought because it was recommend for the terminals. They hold 8 gauge wire well. Unlike a lot of others including the industry leader.

I love this charge controller. It does 12v, 24v, 36v and 48v batteries of all major types. It auto detects the voltage then you just select what type of battery you are using. Attach solar panels and you are set. It does great charging my 36v Li-Ion ebike battery and a 12v SLA. Great well built device.

29,03 ordered, 15.04 received. Very fast. I liked the controller. The menu is clear. Exposed custom mode, lead. Float – 13,5 V, absorb – 14,2 v, equi-14, 8 v. He immediately got into absorb mode and now switched to float. Panel 100 W, AKB-auto 60ah. Test Kit. Voltage and current shows exactly. I can not understand how to manually connect the load. Turns on if you choose in menyu-24hours. T. E. only through the menu. Put the system voltage 12 V instead of auto. In general, I’m happy!
