This typically results in 20–30% more energy harvested compared to a PWM (Pulse Width Modulation) controller, especially when the panel voltage is significantly higher than the battery voltage.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this MPPT controller work with lithium (LiFePO4) batteries?\u003c\/h4\u003e\n\u003cp\u003eA: This controller supports common battery types including sealed lead-acid, gel, and flooded batteries. If you intend to use it with lithium batteries, please verify the charging voltage parameters are compatible with your specific battery pack's requirements before connecting, as lithium chemistries have strict voltage limits.\u003c\/p\u003e\n\u003ch4\u003eQ: What solar panel size do I need for the 30A model on a 12V system?\u003c\/h4\u003e\n\u003cp\u003eA: For the 30A model on a 12V system, the maximum supported PV input power is 360W. You can use one or more panels wired in series or parallel as long as the total wattage stays at or below 360W and the open-circuit voltage (VOC) does not exceed 100V.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I monitor and control this controller remotely using my smartphone?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This controller features built-in WiFi connectivity. After downloading the companion app and pairing the device to your home or site WiFi network, you can monitor real-time charging data, battery status, and adjust settings from your smartphone — iOS or Android — from anywhere with internet access.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this controller suitable for use in an RV or camper van solar setup?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
