Always select the correct battery type and verify charging voltages with the battery manufacturer.\u003c\/p\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eCan I connect a 75V solar array?\u003c\/summary\u003e\u003cp\u003eNo. The array open-circuit voltage must remain below 75V, including the voltage increase that occurs in cold weather. Leave an appropriate safety margin.\u003c\/p\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eCan I connect an inverter to the LOAD output?\u003c\/summary\u003e\u003cp\u003eNo. An inverter must connect directly to the battery through properly sized cables and dedicated overcurrent protection. The controller’s LOAD output is for compatible DC loads up to its 20A rating.\u003c\/p\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eCan this controller be installed outside?\u003c\/summary\u003e\u003cp\u003eNo. Its IP30 protection class has no water-protection rating. Install it indoors in a dry, ventilated location with adequate clearance for heat dissipation.\u003c\/p\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eWhy can charging behavior change near the high-voltage disconnect point?\u003c\/summary\u003e\u003cp\u003eThe controller may limit voltage using PWM behavior near the high-voltage disconnect point to protect the battery.
