Featuring a built-in industrial microcontroller and LCD display, it offers real-time monitoring and user-friendly controls. With multiple safety protections and efficient power management, it extends battery life and simplifies solar energy management for home and commercial use. Note: Best suited for lead-acid batteries; some users report build quality limitations requiring technical tweaks. ## Description desertcart.com : Cxztcl PWM Solar Charge Controller 20A Solar Panel Controller 12V/24V Auto Adjustable LCD Display Solar Panel Battery Regulator with USB Port : Patio, Lawn & Garden Review: I don’t regret buying this! - Works as it should! Easy to use, and have an easy to read display. Review: You get what you pay for. it’s cheap, it works, but it’s inaccurate and low build quality - It was inexpensive. It claims it can work on lithium battery type. It does have adjustable voltage limits , however The Voltage measurement was way off, it would have damaged batteries if used as is. I was able to identify the resistors making the voltage divider internally on the board and modify them to fix voltage accuracy. It Shows only voltage, not charge currents. Switching is all done on the negative side with positive all bussed together internal between solar, battery and load. This limits what can be the load, as it’s common negative terminal must route to the controller. Back thin metal cover is a heat sink, but just slightly presses against internal fets with no proper mounting and poor thermal contact area. I modified my unit to have a real heat sink plate and better thermal transfer. Unless you have the engineering knowledge and time to fix this unit up, I suggest looking at a higher quality unit. ## Features - 【UPGRADED SOLAR CONTROLLER】This solar charge controller automatically manages the operation of solar panels and batteries in solar systems using a built-in industrial microcontroller. It retains user-set parameters, eliminating the need for resetting when the battery is depleted - 【 AUTOMATIC ADAPTATION】Compatible with both 12V and 24V systems, this device automatically adapts to your system's voltage, requiring no manual adjustments. Minor voltage fluctuations are normal - 【COMPATIBLE BATTERY TYPE】This solar controller is designed exclusively for lead-acid batteries, including open, sealed, and gel types. It features auto-battery voltage recognition to prevent misuse and optimize charging. Ensure the battery is fully charged before initial installation - 【SAFE TO USE】This solar charge controller offers intelligent protection against overcurrent, short-circuit, open-circuit, inverse, low voltage, and overcharge with automatic recovery. Features include a dual MOS anti-backflow circuit, low heat generation, improved system efficiency, and extended battery life. Install on a flat, well-ventilated surface - 【LCD DISPLAY】This device features an LCD display for status and data updates, load time control, and manual setting functions for convenient mode switching and parameter configuration. Suitable for home, industrial, and commercial use.
