Compact PWM Solar Controller for 12V and 24V Systems Overview This solar controller offers basic, reliable solar charge and load control for small off grid solar setups. It uses intelligent PWM charging and automatic system voltage recognition to manage charging and protect the battery. The unit is housed in ABS, features a clear digital display, and includes user controls for easy parameter adjustment. Key benefits Reliable charging control: Intelligent PWM charging adapts to system voltage for stable battery charging. Clear system information: Large digital display shows voltage, current, load status, battery power level, and charging status for quick monitoring. Practical protection features: Builtin protections reduce the risk of reverse discharge, reverse connection, undervoltage, overload, and short circuit conditions. Simple setup and adjustment: Double button design makes parameter changes straightforward without complex menus. Compact and durable: ABS housing, compact footprint, and a working temperature range suitable for many outdoor conditions.
