Morningstar's time-tested 600V, 60A MPPT charge controller has the widest PV input voltage range in the solar industry (100-525VDC).
This high-voltage charge controller utilizes TrakStar™ MPPT technology to maximize energy harvest and intelligently charge 48V batteries* in four stages with up to 60A from a PV array or wind turbine. The high-speed sweeping MPPT algorithm minimizes power loss and provides full visibility of the entire power curve - from open circuit to battery voltage.
This model of the Morningstar TriStar MPPT 600V Charge Controller includes a compact on-board DC Disconnect Box, which enables the controller to be used in either positively-grounded or negatively-grounded PV systems.
