Dual Output MPPT Solar Charge Controllers
A dual output MPPT (Maximum Power Point Tracking) solar charge controller is a device that allows you to charge two separate battery banks using power from a single solar array. This type of charge controller offers several advantages over a traditional single-output MPPT charge controller:
-
Increased flexibility: With a dual output MPPT charge controller, you can charge two separate battery banks using the same solar array. This allows you to separate your power storage for different applications or usage, such as one bank for lighting, another for propulsion, etc.
-
Improved system efficiency: By using a dual output MPPT charge controller, you can optimize the charging of each battery bank separately. This can result in a more efficient overall system, as the charge controller can optimize the charging of each bank individually, rather than trying to charge both banks at the same time.
-
Safety and balance: Dual output MPPT charge controllers are useful when you have different types of battery with different characteristics, like one lead-acid and one lithium-ion battery bank. By having separate charging channels, it will prevent mismatches in voltage and charging current, which can be a safety hazard for the system.
-Advanced monitoring and control: dual output MPPT charge controller also offer advanced monitoring and control, you can monitor and adjust settings for each battery bank separately, this allows you to keep track of the charge status and power usage of each bank and respond accordingly.
- Cost-effective solution: With a dual output MPPT charge controller, you can charge two battery banks with a single solar array, rather than having to purchase and install separate arrays for each bank. This can result in significant cost savings.
Overall, a dual-output MPPT solar charge controller offers several advantages over a traditional single-output controller, including increased flexibility, improved system efficiency, and cost savings. Its ability to charge two separate battery banks separately can be particularly useful in off-grid or grid-tie solar power systems, or in applications where multiple battery banks are used, like RV or boat, where you can separate power usage and keep the balance of the battery banks.
These dual-battery solar controller uses advanced MPPT technology to charge two independent batteries or battery banks. The main battery is charged at high power, while a secondary battery is given a trickle charge of up to 1A. This makes it a perfect solar controller for a campervan, motorhome, boat or any other system with 2 batteries (e.g. engine and leisure battery). The main battery will be charged with a majority of the power, whilst the second battery will be trickle-charged to keep it topped up and ready for use.

High Efficiency 20A Dual Battery Mppt Solar Charge Controller With Lcd Display For Solar Panels Up To 260W (12V Battery System) / 520W (24V Battery System)
Dual Battery ChargingThis advanced 20A 12V/24V dual battery solar controller uses advanced MPPT technology to charge two independent batteries or battery banks. The main battery is charged at high power, while a secondary battery is given a trickle charge of up to 1A. This makes it a perfect solar controller for a campervan, motorhome, boat or any other system with 2 batteries (e.g. engine and leisure battery). The main battery will be charged with a majority of the power, whilst the second battery will be trickle charged to keep it topped up and ready for use.Maximum Power Point Tracking (MPPT) TechnologyMPPT technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers. Another benefit of MPPT technology is the wide solar input voltage range - this controller can work not only with standard off-grid 12/24V solar panels, but also with multiple panels with voltage up to 100V. The maximum combined solar input power allowed for this controller is 260W for a 12V battery system or 520W for a 24V system. In particular, this controller will significantly increase efficiency of a solar system where the solar panel voltage is much higher than the battery voltage (e.g. charging a 12V battery with a 36V solar panel).Full Range of Protection Functions:This charge controller features a comprehensive set of electronic protection functions to prevent reverse current at night (from the battery back to the solar panel), over-charging, short circuit, reverse polarity and more. The solar controller case is water resistant to a rating of IP33 when installed, for protection against sprays of water at up to 60 degrees from vertical.Advanced Battery Compatibility:Unlike many other less advanced solar charge controllers, this model is 100% compatible with a broad range of battery types for the main battery, such as Gel, AGM, Lead-Acid Flooded, and Lithium (LiFePO4 or Li-NiCoMn) batteries.Advanced System Functionality:The controller automatically recognises 12/24V battery systems (note a battery should always be connected to the controller first before connecting a solar panel, system voltage recognition based on secondary battery)Built-in LCD screen shows real-time charging parameters such as voltage, current (separately for the solar panel and each battery), battery state of charge, and accumulated charging energyEasy to use buttons allow the user to manually select the battery type (sealed, flooded, gel or Lithium), change the temperature units, and reset the in-built counters (charging energy, min/max voltages)When not in use, the system automatically goes into a low power mode, reducing standby consumption when there is no solar power available, such as when the vehicle is parked in a garageCurrent limiting function (20A) allows the possibility of adding more solar panels to your solar system in the future This model is also compatible with a remote meter MT11 with an LCD screen, which displays system performance information and allows the user to manually adjust parameters and load settings from an easy to use and install remote screen.In addition to the built-in temperature sensor and intelligent heat-dissipating design of this controller, there is also a socket for connecting a remote temperature sensor, which can be attached directly to the battery to measure the battery temperature more precisely. This allows the system to optimise the charging process for lead acid batteries or provide low temperature protection for lithium batteries.
