☀️ High-Voltage Dual MPPT Solar Input

The IVEM8048 accepts solar-array voltages between approximately 90V and 450V DC, with a maximum PV open-circuit voltage of 500V DC.

Its two solar-input strings provide greater flexibility when configuring a larger PV array. The inverter supports up to 8000W of PV input, with the available documentation indicating a 5000W limit for a single PV input.

High-voltage PV operation can help:

• Reduce solar-side current
• Reduce cable losses
• Allow longer panel strings
• Simplify larger PV-array layouts
• Reduce the number of parallel solar strings

🔋 48V Battery Compatibility

The inverter operates with a 48V battery bank and is suitable for compatible:

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

Felicity specifically includes a lithium battery activation function, helping support compatible lithium energy-storage systems.

Battery charging parameters and communication requirements should always be matched to the specific battery model being installed.

📶 Built-In Wi-Fi Monitoring

Built-in Wi-Fi allows system monitoring through the supported Felicity mobile application.

Depending on system configuration, users can monitor information such as:

• Solar generation
• Battery status
• Grid input
• Inverter output
• Charging and discharging
• Operating status
• System warnings

🔗 Parallel Expansion

The IVEM8048 supports up to 6 compatible inverter units operating in parallel, provided the required battery and parallel configuration are installed.

This gives the system room to expand for larger residential or commercial power requirements.

🔌 Battery-Free Operation

A useful feature of the IVEM8048 is support for battery-free operation using PV and utility power.

This allows the inverter to operate selected loads without a connected battery when sufficient solar or grid power is available.

A battery is still required for stored-energy backup and certain parallel configurations.

🛡️ Built-In Protection

The IVEM8048 includes protection features designed to improve operating safety, including:

• Overload protection
• Over-temperature protection
• Output short-circuit protection
• Overcharge protection
• Automatic restart following AC recovery
