Power input options: Supports 12V solar panels or an 18 28V DC power supply, enabling flexible installation in homes, cabins, or vehicles. Battery compatibility: Designed to charge 12V lead acid batteries with capacities from 1 Ah to 1000 Ah, suitable for small to large battery banks. Solar panel compatibility: Compatible with 12V solar panels whose maximum power point voltage is 17.5 18.5V, ensuring proper operation within the MPPT range. MPPT technology: Photovoltaic cell Maximum Power Point Tracking to optimize energy harvest and improve charging efficiency. Benefits and why you need it: Increases charging efficiency by using MPPT to select the operating voltage, supports a wide range of battery sizes, and accommodates both solar and DC powered setups for versatile off grid power. Use scenario 1: Off grid cabin or shed power system. Connect 12V solar panels or a DC supply to charge a 12V lead acid battery bank (1 1000 Ah) for reliable daytime and backup power. Use scenario 2: Recreational vehicles and boats. Install on RVs or boats to maintain and charge 12V batteries from roof mounted solar panels or a DC source, ensuring readiness for lighting, electronics, and starting power. Use scenario 3: Remote monitoring or emergency backup sites. Provide solar or DC powered charging for 12V lead acid batteries in locations without mains power, improving system reliability.
