SRNE ML4860: 60A MPPT Charging Up To 48V Systems
A 48V off-grid system needs a controller that can keep up with a serious array. The SRNE ML4860 (ML4860N15) is a 60A MPPT solar charge controller that works with 12V, 24V, 36V and 48V battery banks and accepts up to 150V of PV input. On a 48V bank it can take up to 3,200W of solar.
Why You'll Love The SRNE ML4860 Controller
Big array capacity. Up to 3,200W of PV at 48V means a single controller can handle a full roof of panels on a cabin or off-grid home.
Higher PV voltage. 150V max open circuit voltage at 25°C lets you run longer series strings and thinner wire.
Scale with parallel units. The datasheet supports 1 to 10 units in parallel as your system grows.
Smart and protected. MPPT tracking above 99%, multiple load control modes and complete charge and discharge protection, with silent natural cooling.
Your life, with the SRNE ML4860 Controller
Your off-grid workshop runs on a 48V battery bank. The ML4860 pulls everything it can from the array each morning, and by afternoon the bank is full and ready for the evening's tools and lights. No generator, no fuss.
