This energy controller is designed to manage solar charging and DC loads in a variety of offgrid and vehicle applications. Available in model options 80 and 100 with SYSLCD 80A listed as a product option, the unit supports automatic system voltage selection and combines MPPT and PWM charging algorithms to improve conversion efficiency. Key benefits Improves charging efficiency by combining MPPT and PWM modes to capture more available solar power under varying conditions. Automatically detects and supports 12V, 24V, 36V, and 48V systems, simplifying installation and ensuring compatibility with common battery banks. current capacity with selectable maximum current ratings of 80A or 100A to handle larger arrays and heavier loads. Dual 5V USB outputs for convenient charging of small devices directly from the controller. configuration to fit different system requirements and installation scenarios. Main features Rated voltage: 12V 24V 36V 48V AUTO for automatic voltage recognition and selection Charging model: MPPT plus PWM for optimized power conversion Maximum current: 80A or 100A depending on model choice USB output: Dual 5V ports for mobile device charging Applications supported: Charger controller, solar system controller, solar working station, lighting controller Practical applications Remote cabin or offgrid home: Manage solar panels and battery charging while powering LED lighting and small appliances, with automatic voltage selection to match the battery bank. Mobile power for RVs and boats: Regulate charging from roof or portable panels and provide USB charging for phones and small electronics. Temporary or remote work sites: Control solar arrays and lighting systems at a construction site or outdoor workstation, improving usable power through MPPT plus PWM control. Additional notes Model options 80 and 100 are available to match current requirements; the product supports where needed. Use the controller as the central management device for solar charging and DC load control in systems that require reliable voltage recognition and improved conversion performance.
