6kW Hybrid Solar Inverter with Dual AC Inputs and Outputs and Touchscreen Control for Installers

6kW Hybrid Solar Inverter with Dual AC Inputs and Outputs

The Voltertech INV-6KW-51.2V-W is a 6kW single-phase hybrid solar inverter designed for solar installers and energy storage system integrators. Its configuration includes two independent AC inputs, two outputs, a current transformer (CT), touchscreen control and Wi-Fi connectivity. These features make it a practical choice for projects requiring coordinated solar, battery and AC power connections.

With 6000W rated AC output, up to 9000W PV input and a nominal 48V battery platform, the inverter supports grid-tied, hybrid and off-grid system configurations.

Dual AC Inputs and Outputs for System Integration

The inverter features two independent AC inputs and two outputs, giving installers additional connection options when planning an integrated solar power system.

Before installation, the AC wiring diagram should identify the available power sources, connected load circuits, electrical protection and required operating mode. The function of each input and output must follow the approved inverter wiring diagram and configuration instructions.

This is particularly important for projects involving multiple AC connections, where the exact switching and load management behavior must be verified before commissioning.

Touchscreen Control, CT and Wi-Fi Connectivity

A built-in touchscreen provides a local interface for inverter settings and operating information. Wi-Fi connectivity supports remote access and monitoring through the compatible monitoring system.

The feature list also includes a current transformer (CT), while RS485, CAN and dry contact interfaces are available for system communication and integration.

Installers should confirm CT placement, communication wiring and the supported monitoring functions according to the actual electrical design.

9kW PV Input and 48V Battery Integration

The inverter supports a maximum PV input power of 9000W with two MPPT trackers. Its MPPT voltage range is 50–450Vdc, allowing installers to configure solar strings according to the selected PV modules and electrical limits.

The nominal battery voltage is 48Vdc, with a maximum charging current of 135A. Compatible 51.2V LiFePO4 batteries may be used when their operating voltage, charging requirements and BMS communication protocols match the inverter.

Battery capacity should be selected according to the project's energy demand, required backup duration and available charging conditions.

Single-Phase Operation and System Expansion

The inverter provides 220/230/240VAC single-phase output for compatible electrical systems. Its specification also supports parallel operation of up to six units for single-phase supply.

For larger installations, installers should confirm the approved parallel wiring, communication connections, battery configuration and protection requirements before combining multiple inverter units.

Technical Specifications

Applications for Solar Installers

This 6kW hybrid inverter can be considered for residential solar installations, small office energy storage systems and compatible solar battery backup projects. Its AC connection arrangement, communication interfaces and touchscreen make it relevant for installers who need to plan and commission multiple components within one solar energy system.

Project suitability depends on the connected electrical loads, solar array configuration, battery specifications and local electrical installation requirements.

Frequently Asked Questions

1. What is the advantage of having two AC inputs and two outputs?

The configuration provides additional AC connection options for system design. The permitted power sources, output functions and operating logic must be confirmed using the manufacturer's wiring documentation.

2. Can one AC input be connected to a generator?

Generator compatibility and automatic switching functions must be verified from the installation manual and supported operating modes. Two AC inputs alone do not confirm generator compatibility.

3. Can the inverter work with a 51.2V LiFePO4 battery?

It uses a nominal 48V battery platform. A 51.2V LiFePO4 battery may be compatible if its operating voltage, charging current and BMS communication protocol meet the inverter requirements.

4. Can multiple 6kW inverters operate together?

The specification supports up to six units in parallel for single-phase supply. The installation must follow the approved parallel communication, AC wiring and battery connection requirements.

5. What information is needed before ordering?

Please provide the PV module specifications, battery model, AC supply details, expected loads and required operating mode. An electrical connection diagram is also helpful when the project involves multiple AC inputs or outputs.
