The Felicity Solar IVEM12048-II is a powerful 12kW low-voltage hybrid/off-grid inverter designed for large homes, offices, shops, commercial premises and high-demand solar installations.

It combines an inverter, MPPT solar charger and battery charger in one unit, with support for two solar PV strings, built-in Wi-Fi monitoring, generator compatibility, smart load control and parallel expansion. Felicity lists the IVEM12048-II as a 48V high-frequency off-grid inverter suitable for single-phase operation, with three-phase configuration possible using at least three units.

• 🏠 Single-phase operation
• ⚡ Three-phase configuration possible with at least 3 compatible units
• ☀️ Intelligent feed-in function for excess PV energy

☀️ Dual MPPT Solar Input

The IVEM12048-II supports two solar-input strings and up to 15kW total PV input.

This means the solar array can be divided into:

• ☀️ PV Input 1: Up to 7.5kW
• ☀️ PV Input 2: Up to 7.5kW
• 🔆 Total PV Capacity: Up to 15kW

The dual-input design provides greater flexibility where panels are installed on different roof sections or where two separate PV strings are required.

🔋 High-Power 48V Battery Charging

The inverter uses a 48V battery system and supports a maximum charging current of up to 240A, making it suitable for larger energy-storage installations.

Compatible battery systems may include:

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

The inverter also includes a lithium battery activation function, helping restore compatible lithium batteries whose BMS has entered a protection or low-power state.

📶 Built-In Wi-Fi Monitoring

The built-in Wi-Fi function allows system monitoring through Felicity Solar's supported mobile application.

Users can monitor information such as:

• ☀️ Solar generation
• 🔋 Battery condition
• ⚡ Inverter output
• 🔌 Grid or generator input
• 🔄 Charging and discharging status
• ⚠️ Operating warnings and faults

Built-in Wi-Fi is listed as standard for the IVEM 8–12kW-II series.

🔌 Generator & Smart Load Support

The IVEM12048-II is compatible with both utility power and generator input.

A useful feature is that the generator input port can be changed into a smart output port, allowing selected loads to be controlled independently. The operating duration of this smart output can also be customised.

☀️ Feed Excess Solar Power to Loads

Felicity also includes an intelligent feed-in function designed to make use of excess solar generation rather than wasting available PV energy.

Excess solar power can be redirected toward grid-side loads, improving overall solar utilisation.

🔗 Parallel Expansion

The IVEM12048-II supports up to 6 compatible inverter units in parallel.

This makes it suitable for systems that may need more output capacity in the future.

With at least 3 compatible units, the platform can also be configured for three-phase operation. 

🛡️ Built-In Protection

The inverter includes several protection and recovery functions:

• 🛡️ Overload protection
• 🌡️ Over-temperature protection
• ⚡ Short-circuit protection
• 🔄 Automatic restart after AC recovery
• ❄️ Cold-start function
• 🔋 Lithium battery activation
