915 Generation MPPT Solar Charge Controller Solar Regulator for 12V 24V Lithium Battery With BT20A

Functional characteristics1Due to an advanced digital power technology the circuit energy conversion efficiency is as high as 98% 2It 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
3Available in multiple battery types and support charging procedures of various types of batteries such as lithium battery battery sealed battery vented battery lithium battery etc 4A current-limited charging mode is available When the power of solar panel is too 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
5Support automatic identification of lead-acid battery voltage External LCD screen or Bluetooth module can be connected for viewing of equipment operating data and status and modification of controller parameters is supported 6Support standard Modbus protocol to meet communication needs in different occasions 7Built-in over-temperature protection mechanism 8Temperature compensation and automatic adjustment of charge and discharge parameters help to battery life
9Solar panel short circuit protection battery open circuit protection and lightening protection etc Protection Waterproofing protection Rating IP32 Input power limited protection When the power of solar panel is higher than the rated value the controller will limit the power of solar panel within the rated power range to prevent damage by over current and the controller enter the current-limiting charge
Battery reverse polarity protection If the battery polarity is reversed the system will not work it will not burn out the controller PV input end voltage is too high If the voltage at the PV array input end is too high the controller will automatically shut off the PV input PV input end short circuit protection If the voltage at the PV array input end is short circuited the controller will turn off charging after short circuit is removed charging will automatically

Introduction
MPPT technologyenables maximum energy tracking for solar panel and llows the controller to quickly and accurately track the maximum power point of PV array in any environment
This product can be connected to an external LCD screen or Bluetooth communication module and PC Upper Computer for dynamic display of operating status operating parameters controller logs control parameters etc Adopting standard Modbus communication protocol and providing overall electronic fault self-test and powerful electronic protection functions which minimize components damage due to installation error and system failure
PV input reverse polarity protection When the polarity of PV array is reversed the controller will not be damaged and normal operation will continue after wiring error is corrected
Night reverse charging protection Prevent battery discharge through the solar panel at night
-protection
Over-temperature protection When temperature of the controller exceeds the set value it will reduce charging power or stop charging
