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.\u003c\/p\u003e\n\u003cp\u003eMaximum Power Point Tracking (MPPT) Technology MPPT technology ensures the maximum efficiency of your solar system and significantly outperforms standard PWM solar controllers.\u003c\/p\u003e\n\u003cp\u003eAnother 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.\u003c\/p\u003e\n\u003cp\u003eThe 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\u003c\/p\u003e\n\u003cp\u003eFunctions: 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.\u003c\/p\u003e\n\u003cp\u003eThe 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. \u003c\/p\u003e\n\u003cp\u003eAdvanced 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.\u003c\/p\u003e\n\u003cp\u003eAdvanced 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) \u003c\/p\u003e\n\u003cp\u003eBuilt-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 energy\u003c\/p\u003e\n\u003cp\u003eEasy 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)\u003c\/p\u003e\n\u003cp\u003eWhen 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 garage\u003c\/p\u003e\n\u003cp\u003eCurrent limiting function (20A) allows the possibility of adding more solar panels to your solar system in the future\u003c\/p\u003e\n\u003cp\u003eDimensions\u003cspan\u003e: 243.7 x 158 x 63 mm\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptional Extra \u003c\/strong\u003eMT11 remote display for Dual Battery MPPT \u003c\/p\u003e\n\u003cp\u003eThis high quality, brand new remote display \/ monitor can be used with 10A - 30A dual battery MPPT solar charge controllers\/regulators (DM series).
