Felicity Solar 4kW 24V Off-Grid Solar Inverter

Felicity Solar 4kW 24V Off-Grid Solar Inverter

The Felicity Solar IVEM4024-II is a 4kW off-grid solar inverter designed for 24V battery systems. It combines a pure sine-wave inverter, built-in MPPT solar charge controller, utility or generator charging, Wi-Fi monitoring and programmable operating settings in a single unit.

With support for up to 6,000W of connected PV input, a 500V maximum PV open-circuit voltage and 120A maximum solar charging current, the inverter provides a capable foundation for household backup systems, cabins, workshops and other properties requiring an independent solar and battery solution.

4kW Pure Sine-Wave Output

• 4,000VA rated apparent output power
• 4,000W rated output power
• 230V nominal AC output
• Pure sine-wave output waveform
• 50Hz or 60Hz adjustable output frequency
• Electric-motor starting capability
• Output short-circuit protection
• Standalone operation only; parallel operation is not supported

High-Voltage MPPT Solar Input

• 6,000W maximum PV input power
• 500V maximum PV open-circuit voltage
• 60V to 500V PV operating range
• 60V minimum PV start-up voltage
• 27A maximum PV input current
• 120A maximum solar charging current

The connected solar-array voltage and current must remain within the inverter limits under all operating conditions. The installer must verify string voltage at the lowest expected site temperature before connecting the panels.

24V Battery Charging

• 24V nominal DC battery voltage
• 120A maximum combined charging current from PV and grid or generator
• Charging-current adjustment from 10A to 120A
• Lithium-battery activation function
• Solar plus grid or generator charging support
• Overcharge protection

The configured charging current must suit the connected battery capacity, battery-management system and cable protection. Battery compatibility must be confirmed before installation.

Generator and Smart-Load Port

The dedicated generator input can be reconfigured as a smart output port with a customisable operating duration. This provides flexible control for compatible generators or selected loads according to the completed system design.

Built-In Wi-Fi Monitoring

Built-in Wi-Fi enables supported mobile monitoring through the required Felicity Solar application. The LCD interface also allows important operating parameters such as charging current, input-voltage behaviour and charging priority to be configured at the inverter.

AC Input and Battery-Free Operation

• 230V nominal AC input
• 90V to 280V AC input range
• 280V maximum AC input voltage
• Automatic 50Hz or 60Hz frequency detection
• Pass-through operation without a battery
• Inverter operation without a battery
• Automatic restart when AC supply recovers
• Cold-start functionality

Protection Features

• Overload protection
• Overtemperature protection
• Short-circuit protection
• Battery overcharge protection

Dimensions and Operating Conditions

• Product dimensions: 430 x 310 x 120mm
• Package dimensions: 507 x 387 x 197mm
• Net weight: 10.4kg
• Operating-temperature range: -10°C to +50°C

Warranty and Installation

The inverter carries a two-year warranty, subject to the manufacturer’s applicable warranty policy and installation requirements. Installation, cabling, protection equipment and commissioning are not included in the product price.

The inverter must be installed by a qualified solar installer or electrician. Final suitability depends on the battery configuration, solar-array design, cable sizing, protection equipment, load profile and installation environment.
