To safely charge a 12V LiFePO4 battery, use a LiFePO4-compatible charger with a voltage of 14.2V–14.6V and a CC-CV charging profile. Charge at 0.2C–0.5C (e.g., 20A–50A for a 100Ah battery) and stop when the current drops below 0.05C. Avoid overcharging, deep discharging, and charging below 0°C (32°F) unless the battery supports low-temp charging. For solar charging, use an MPPT controller, and for alternators, use a DC-DC charger. Always monitor temperature and voltage for safety.

To install a pure sine wave inverter, begin by selecting a suitable location with good ventilation and secure mounting. Connect the inverter to the battery (for off-grid systems), ensuring correct polarity and fuse protection. For grid-tied systems, connect the AC output to your electrical panel, ensuring proper grounding. Test the system by checking voltages and verifying pure sine wave output, and adjust settings as needed. Always prioritize safety by using the correct tools and safety equipment, and consult a professional if you are unfamiliar with electrical installations. Regular maintenance is also essential to ensure the system’s longevity and performance.
