✅ Certifications & Standards:

💡 Pro Tips:

• 🔋 Battery Sizing: For optimal performance with the SCMKII-3K-24, use a 24V deep-cycle battery bank with capacity appropriate for your needs. A 200Ah battery bank provides approximately 2-3 hours of runtime at 1500W load -2.

• ☀️ Solar Array Sizing: The MPPT controller supports 30-80V DC input. For 24V systems, configure solar panels in series to achieve 60-80V VOC for optimal MPPT performance -2.

• ⚡ Load Management: The 6000W surge capacity handles startup surges from motors and compressors, but continuous loads must stay within 3000W rating -1.

• 📊 Efficiency Tip: The inverter achieves maximum efficiency (93%) at 50-80% load. Operating consistently at very light loads reduces overall system efficiency -2.

• 🔧 Battery Selection: The inverter supports multiple battery chemistries including LiFePO₄. Ensure battery settings are configured correctly for your specific battery type to maximize lifespan -2.

⚠️ Important Note: This high-frequency inverter is designed for off-grid and backup applications. For heavy industrial loads like large motors, welders, or pumps with high startup surges, consider a low-frequency inverter with higher surge capacity.
