MPPT Solar Charge Controller 20A 30A 40A 50A Solar Regulator 12V 24V For Max 1320W Input Lithium Battery With BT-2 RM-6 LCD ,Safe to Use - WITH REMOTE DISPLAY_40A

1.Due to an advanced digital power technology, the circuit energy conversion efficiency is as high as 98%. 2.It provides an active charging voltage regulation feature. At battery open circuit or lithium battery BMS overcharge protection, the controller battery terminal will output the rated charging voltage value. 3.Available in multiple battery types and support charging procedures of various types of batteries such as lithium battery, colloidal battery, sealed battery, vented battery, lithium battery, etc. 4.A current-limited charging mode is available. When the power of solar panel is too large and the charging current is higher than the rated valve, the controller automatically reduces the charging power so that the solar panel can operate at the rated charging current. 5.Support automatic identification of lead-acid battery voltage. External LCD screen or module can be connected for viewing of equipment operating data and status, and modification of controller parameters is supported.
