MPPT 40A Programmable Solar Charge Controller 12/24V for RV & Marine MC2440

• Small unit - no onboard display.
• may be paired with a BT2 Bluetooth unit to see display on your smart phone (not included)
• may be paired with a RM6 remote display unit (not included)
• Can be used with lead acid, gel, flooded, SiO2, carbon foam, lithium ion batteries (many presets. custom settings using BT2 or RM6)

With industry-leading PowerCatcher MPPT technology, the MC series solar charge controller enables maximum energy tracking for solar panel. This technology allows the controller to quickly and accurately track the maximum power point of PV array in any environment, obtain the maximum energy of solar panel in real time, and significantly increase energy utilization efficiency of the solar energy system.

40A Charge Controller - compact size for RV use - Maximum PV input: 520W/12V 1040W/24V

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. The user can look up various parameters and can modify the control parameters as needed to suit different system requirements.

The controller adopts standard Modbus communication protocol, which is convenient for the user to view and modify the parameters of the system. Meanwhile, the company provides free monitoring software that can maximize the convenience for users to meet different needs of remote monitoring.

The controller provides overall electronic fault self-test and powerful electronic protection functions which minimize components damage due to installation error and system failure.

◆ A built-in maximum power point tracking (MPPT) algorithm can significantly increase energy utilization efficiency of the photovoltaic system, which is about 15% to 20%higher than traditional PWM charging.
◆ 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.
◆ MPPT tracking efficiency is up to 99.9%.
◆ Due to an advanced digital power technology, the circuit energy conversion efficiency is as high as 98%.
◆ 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.
◆ 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.
◆ 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.
◆ Support standard Modbus protocol to meet communication needs in different occasions.
◆ Built-in over-temperature protection mechanism ensures that when temperature exceeds the set value of the device, the charging current decreases linearly with the temperature, thereby reducing the temperature rise of controller and avoiding high temperature damage.
◆ Temperature compensation and automatic adjustment of charge and discharge parameters help to improve battery life.
◆ Solar panel short circuit protection, battery open circuit protection and TVS lightening protection etc.

Remote Meter (RM6) and Bluetooth (BT-2) Available but not included.

The controller setting for the type of battery can be changed without the use of a Bluetooth meter (BT-2) or the remote display (RM-6). Use a paperclip to hold in the set button until the battery light starts to flash, then press the set button until the colour indicates the type of battery you are using. For custom charge settings, you need to use the BT-2 or the RM6, but the basic battery type choice does not require the remote. This controller will sense if your battery bank is 12 or 24V.
