☀️ High-Voltage Solar Input

The IVEM6048 II supports solar PV voltage of up to 500V DC, allowing multiple solar panels to be arranged in higher-voltage series strings.

Benefits of high-voltage PV input include:

• Lower solar-array current
• Reduced cable losses
• More flexible panel-string design
• Cleaner PV wiring
• Easier integration of larger solar arrays
• Better suitability for longer cable runs between panels and inverter

The exact MPPT operating range, maximum PV wattage and maximum PV input current should be confirmed from the official Felicity Solar datasheet before designing the solar array.

🔋 48V Battery System

The inverter operates on a 48V DC battery bank, making it suitable for medium-to-large solar installations.

Depending on the inverter configuration, compatible battery options may include:

• 🔋 51.2V LiFePO₄ lithium batteries
• 🔋 48V lithium battery banks
• 🔋 Gel batteries
• 🔋 AGM batteries
• 🔋 Deep-cycle lead-acid battery banks

Typical configurations may include:

• One compatible 48V / 51.2V lithium battery
• Four identical 12V batteries connected in series
• Larger 48V battery banks for extended backup

Battery charging parameters should always be configured for the exact battery chemistry and model.

🌊 Pure Sine Wave Output

The pure sine wave output provides clean and stable AC power suitable for sensitive electronics and many motor-driven appliances.

Benefits include:

• Stable output voltage
• Reduced electrical noise
• Better compatibility with electronics
• Suitable operation of refrigerators and selected pumps
• Improved performance of computers and communication equipment

✅ Why Choose a 48V 6kW System?

A 48V architecture is particularly suitable for higher-power installations because it reduces battery-side current compared with equivalent 12V or 24V systems.

This can provide:

• Improved system efficiency
• More manageable battery currents
• Better suitability for larger lithium batteries
• Reduced cable losses
• Easier expansion of energy-storage capacity
• Better support for higher household loads

⚠️ Solar Panel Configuration

Because this inverter supports PV input of up to 500V DC, the solar-panel string must be properly calculated before installation.

Always confirm:

• ☀️ Panel open-circuit voltage (Voc)
• 🔆 Panel maximum-power voltage (Vmp)
• ⚡ Maximum inverter PV current
• 📈 Inverter MPPT operating-voltage range
• 🔋 Maximum permitted PV array wattage
• 🌡️ Increase in panel Voc during colder conditions
• 🛡️ Required DC isolators and surge protection

The total open-circuit voltage of panels connected in series must never exceed the inverter's maximum permitted PV input voltage.
