SRNE MC Off-Grid MPPT 20A 30A 40A 50A Solar Charge Controller 12V/24V Auto Max 100V Bluetooth Display Solar Battery Regulator System

US $60.30-148.50

Overview

This product adopts industry-leading Power Catcher MPPT technology,enables 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.

For installation safety, we recommend a wiring sequence as below,

Feature

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 Bluetooth module can be connected for viewing of equipment operating data and status, and modification of controller parameters is supported.

6.Support standard Modbus protocol to meet communication needs in different occasions.

7.Built-in over-temperature protection mechanism.

8.Temperature compensation and automatic adjustment of charge and discharge parameters help to improve battery life.

9.Solar panel short circuit protection, battery open circuit protection and TVS 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 but 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 recover.

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.

TVS lightning protection

Over-temperature protection: When temperature of the controller exceeds the set value, it will reduce charging power or stop charging.
