The unit accepts PV input voltages up to 100V and supports a wide range of battery chemistries (Flooded, AGM, GEL, Lead-Acid, LiFePO4 and other lithium types), letting you tailor charge parameters on the LCD. Installation follows the recommended sequence—battery, solar panel, then load—to prevent configuration errors.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the controller adapt to different system voltages and solar array sizes?\u003c\/h3\u003e\n\u003cp\u003eThe PowMr 30A automatically senses the connected battery system and configures itself for 12V, 24V, 36V, or 48V operation.
