MPPT Solar Charge Controller 20A/30A/40A/50A 12V/24V — Home System Lithium Battery Regulator with Short-Circuit & Multi Safety Protection

High-efficiency MPPT charge controller for 12V/24V home solar systems, offered in 20A, 30A, 40A and 50A models. Built with advanced digital power technology, the circuit energy conversion efficiency is as high as 98%. The unit provides short-circuit protection and multiple safety protections for reliable operation. Active charging and voltage-stabilization are supported: if the battery is open or the lithium battery BMS indicates overcharge, the controller’s battery terminal outputs the rated charging voltage value. A current-limiting charging mode is included — when the solar panel array produces more power and the charging current exceeds the rated value, the controller automatically reduces charging power so the solar panel works at the rated charging current. This controller supports a variety of battery types and charging procedures, including lithium batteries, gel batteries, sealed batteries, exhaust batteries, and lithium batteries. It also supports automatic identification of -acid battery voltage. You can connect an LCD screen or a Bluetooth module to monitor operating data and device status, and to modify controller parameters as needed.
