Dual Battery Charging

10A 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).

Using the most advanced Maximum Power Point Tracking (MPPT) technology to track the maximum power voltage point of solar panels as it varies depending on sunlight exposure and temperature. This 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 input solar power allowed for this controller is 130W for a 12V battery system or 260W 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).

Featuring a comprehensive set of electronic protection functions to ensure the maximum possible efficiency of your solar system. Including: reverse current prevention at night (from the battery back to the solar panel), automatic cut off to prevent over-charging and deep discharge, solar panel over voltage, over load, short circuit and reverse polarity protection. The controller also has self-diagnostic capability and highlights any system errors using advanced fault-targeting technology.

• The controller automatically recognises 12/24V battery systems (note a battery should always be connected to the controller first before connecting a solar panel)
• Built-in LCD screen shows real-time charging parameters such as voltage, current (separately for solar panel / load), battery state of charge, accumulated charge and discharge energy
• Easy to use buttons allow the user to manually select the battery type (sealed, flooded or gel) and program load settings (e.g. set timers for lighting, fans, pumps etc).
• When not in use, the system automatically goes into a low power mode, reducing standby consumption when there is no solar power available.
• Current limiting function (10A) allows the possibility of adding more solar panels to your solar system in the future.
• Suitable for panels up to 130W (12V)
• Maximum solar panel voltage: 100V
• Temperature sensor for automatic compensation
• 3 pairs of terminals (solar panel, battery 1, battery 2) for wire up to 4mm², load terminals for connecting 12V loads (such as lights) if desired
• Pre-programmed charging parameters for Sealed, Gel, Flooded batteries, optional User-defined and Lithium battery types
• Dimensions: 227.2 x 143 x 58.1 mm
