8kW Hybrid Solar Inverter with CT and Touchscreen Control for Installer-Focused Solar Projects

8kW Hybrid Solar Inverter with CT and Touchscreen Control

The Voltertech INV-8KW-51.2V-W is an 8kW single-phase hybrid solar inverter designed for solar installers, distributors and energy storage system integrators. It combines current transformer (CT) support, touchscreen operation, Wi-Fi connectivity and dual MPPT tracking within an IP65-rated enclosure.

With 8000W rated AC output, up to 13.5kW PV input and a nominal 48V battery connection, the inverter supports solar and battery system integration for residential and small commercial projects.

Current Transformer Integration for Solar Installations

The inverter's feature list includes a current transformer (CT) for electrical current measurement in supported system configurations. Proper CT installation is important when integrating the inverter with the site's AC electrical system.

Installers should verify the approved CT type, installation position, wiring direction and related inverter settings before commissioning. Specific functions such as export limitation or grid power control must be confirmed from the applicable installation manual.

Touchscreen Interface and Wi-Fi Connectivity

The built-in touchscreen provides a convenient local interface for viewing operating information and accessing supported inverter settings. This allows installers to perform on-site configuration without relying entirely on remote monitoring tools.

Wi-Fi connectivity is available for supported monitoring applications. RS485, CAN and dry contact interfaces are also provided for communication and integration with compatible battery and electrical equipment.

Dual MPPT Solar Input Configuration

The inverter supports up to 13,500W of PV input through two MPPT trackers. The specified maximum input currents are 18A and 36A, with an MPPT operating voltage range of 50–450Vdc.

This input arrangement gives installers options when designing PV strings with different current requirements. Solar module voltage, operating current, string configuration and environmental conditions must all be checked against the inverter limits.

48V Battery Integration and System Expansion

The inverter uses a nominal 48Vdc battery platform and supports a maximum charging current of 190A. Compatible 51.2V LiFePO4 batteries may be used when their operating voltage, charging limits and BMS communication protocols match the inverter.

The series specification also lists parallel operation for multi-inverter installations. Final parallel arrangements should be confirmed using the approved wiring instructions, communication settings and electrical protection requirements.

Technical Specifications

Applications for Solar Installers

The 8kW hybrid inverter can be considered for residential solar storage, small business installations and compatible hybrid or off-grid power systems. Its touchscreen, CT support and communication interfaces are useful considerations when installers need to configure and monitor different components within one electrical installation.

Frequently Asked Questions

1. What is the purpose of the CT in this hybrid inverter?

A current transformer measures electrical current for supported monitoring or control functions. Its exact application, wiring position and available inverter settings should be confirmed from the installation manual.

2. Can the inverter be configured without Wi-Fi?

The inverter includes a local touchscreen interface for supported settings and operating information. Wi-Fi is available for compatible remote monitoring functions.

3. Can I connect a 51.2V LiFePO4 battery?

The inverter uses a 48Vdc nominal battery system. Compatibility with a specific 51.2V LiFePO4 battery depends on its voltage range, charging limits and supported CAN or RS485 protocol.

4. Is the IP65 inverter suitable for outdoor installation?

IP65 provides dust protection and resistance to water jets under the applicable rating. Actual outdoor suitability must also consider mounting location, temperature, sunlight exposure and manufacturer installation requirements.

5. What details should installers provide before ordering?

Please provide the solar panel model, PV string configuration, battery specifications, grid voltage and required operating mode. For projects using CT measurement or multiple inverters, an electrical wiring diagram is also helpful.
