Product Name: 12V 24V 36V 48V 85A 100A MPPT Solar Charge Controller Model NO.: MC-4885/48100 Rated Voltage: 48V Application: Solar System Controller, Charger Controller, Lighting Controller, Solar Working Station Certification: ISO, CE Condition: New Trademark: PUGU Transport Package: Carton Origin: China Product Description Product features:1, PowerCatcher maximal power Tracking technology can still trace the maximal power point of solar battery in the complicated environment. Compared with traditional MPPT Tracking technology, it enjoys higher response speed and higher Tracking efficiency.2, MPPT charge efficiency is greater than traditional PWM charge efficiency by about 15% ~20%.3, MPPT Tracking efficiency can be as much as 99.9%.4, Adopting advanced digital power technology, the circuit energy conversion efficiency can be as much as 98%.5, The products support lithium batteries, charging output has active voltage stabilization function. In case of open circuit of lithium batteries or BMS overcharging protection, the storage battery end of the controller shall output stable target voltages in time, thereby possessing good lithium electric activation function.6, Preset a variety of battery types: lithium batteries, sealed batteries, colloidal batteries, open batteries and self definition.7, Lead-acid batteries support temperature compensation function.8, With charging line loss compensation, the voltage of the battery terminal can be accurately controlled.9, With current-limiting charging, in case of too much battery panel power (charging current is greater than rated current), the controller automatically reduces the charging power so that it can operate within the rated charging current.10, With built-in over temperature protection mechanism, when the temperature exceeds the set temperature value, the charging power shall decline in a linear way with the temperature.11, It supports parallel function and breaks through the power limit of single unit. Therefore, combination of several units can meet greater charging power.12, With built-in bluetooth 4.0BLE module, it can achieve mobilephone APP data interaction.13, Supporting standard Modbus protocol, it provides protocol technology support to facilitate secondary development and application by users.14, Programmable relay output
