Morningstar TriStar TS-45 PWM Solar Charge Controller (45A / 12-48V)

The Morningstar TriStar TS-45 is a heavy-duty, 3-in-1 solar charge controller, DC load controller, or diversion regulator rated for 45 Amps in 12V, 24V, 36V, or 48V DC battery systems. Built with an oversized heatsink for maximum thermal management, the TS-45 operates at 100% rated capacity up to 60°C ambient without thermal derating. It delivers 4-stage constant-voltage series PWM charging for Lead-Acid, Lithium, and NiCd battery chemistries in remote industrial, SCADA, and telecom power systems.
