The Enerdrive 40Amp Solar Charge Controller is a premium high capacity solar management solution designed for demanding off-grid power systems in caravans, motorhomes, 4WDs, marine vessels and remote installations. Featuring advanced Maximum Power Point Tracking (MPPT) technology, the controller continuously monitors and adjusts to the optimal solar operating point, maximising solar harvest and delivering up to 20–30% greater charging efficiency compared to conventional PWM regulators.\u003cbr\u003eEngineered for larger solar arrays, the EN43540 supports both 12V and 24V battery systems with automatic voltage detection and is compatible with lithium (LiFePO₄), AGM, gel, sealed and flooded batteries. Its intelligent multi stage charging algorithm helps optimise battery performance, improve charging consistency and extend overall battery lifespan.\u003cbr\u003eThe integrated LCD display provides real time monitoring of solar input, charging current, battery voltage, load status and energy statistics, while comprehensive electronic protections safeguard your system against reverse polarity, overheating, overcharging and short circuits. With ultra fast MPPT tracking efficiency and robust Australian ready construction, the EN43540 is ideal for high performance mobile and off-grid solar systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures and Benefits:\u003c\/strong\u003e\u003cbr\u003eAdvanced MPPT technology delivers up to 20–30% more charging efficiency compared to PWM controllers\u003cbr\u003eAutomatic 12V \/ 24V system voltage detection\u003cbr\u003eSupports lithium (LiFePO₄), AGM, gel, sealed and flooded lead acid batteries\u003cbr\u003eIntelligent multi stage charging improves battery health and lifespan\u003cbr\u003eUltra fast MPPT tracking efficiency up to 99.5%\u003cbr\u003eHigh DC\/DC conversion efficiency up to 98.6%\u003cbr\u003eLCD display provides real time system monitoring and energy statistics\u003cbr\u003eComprehensive electronic protection against overcharge, reverse polarity, overheating and short circuits\u003cbr\u003eWide PV input voltage range supports modern high voltage solar panels\u003cbr\u003eFanless cooling design for quiet and reliable operation\u003cbr\u003eRS485 communications port included for future monitoring and integration options\u003cbr\u003eCompact and durable design ideal for caravans, RVs, boats and remote solar installations\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eController Type: MPPT (Maximum Power Point Tracking)\u003cbr\u003eSystem Voltage: 12V \/ 24V Auto Select\u003cbr\u003eBattery Voltage Range: 8V – 32V\u003cbr\u003eRated Charge Current: 40A\u003cbr\u003eMaximum Load Output Current: 40A\u003cbr\u003eMaximum PV Open Circuit Voltage: 100V (92V @ 25°C)\u003cbr\u003eMPPT Operating Voltage Range: Battery Voltage +2V to 72V\u003cbr\u003eRecommended PV Array Size: 600W (12V) \/ 1200W (24V)\u003cbr\u003eMaximum PV Array Size (Overdrive): 720W (12V) \/ 1440W (24V)\u003cbr\u003eEfficiency (Maximum): 98.60%\u003cbr\u003eSelf Consumption: ≤30mA (12V) \/ ≤16mA (24V)\u003cbr\u003eCharging Stages: MPPT \/ Bulk \/ Absorption \/ Float\u003cbr\u003eSupported Battery Types: Lithium (LiFePO₄), AGM, Gel, Flooded, Sealed\u003cbr\u003eRS485 Interface: (RJ45)\u003cbr\u003eGrounding: Common Negative\u003cbr\u003eProtection Rating: IP33\u003cbr\u003eOperating Temperature: -25°C to +50°C\u003cbr\u003eStorage Temperature: -20°C to +70°C\u003cbr\u003eRelative Humidity: ≤95% Non-Condensing\u003cbr\u003eDimensions: 255mm (L) × 185mm (W) × 67.8mm (H)\u003cbr\u003eMounting Hole Size: Ø5mm\u003cbr\u003eMaximum Cable Size: 13.2mm² (6AWG)\u003cbr\u003eWarranty: 2 Years\u003cbr\u003eUser Manual, click here\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is Included:\u003c\/strong\u003e\u003cbr\u003e1 x Enerdrive EN43540 MPPT 40Amp Solar Charge Controller\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImportant Information:\u003c\/strong\u003e\u003cbr\u003eNot what you are looking for?
