Single-Phase Hybrid Inverters

Single-Phase Hybrid Inverters include hybrid inverter solutions designed for single-phase electrical systems typically used in residential and small commercial installations. This collection focuses on inverter models that combine solar input, battery storage integration, and grid interaction within a single unit.

The range is intended for solar PV systems where energy storage, backup functionality, and flexible power management are required. Single-phase hybrid inverters support integration with compatible lithium battery systems and may operate in on-grid, off-grid, or hybrid modes depending on the specific model and system configuration.

All products are supplied by established manufacturers and are intended for integration with compatible solar panels, battery storage systems, and electrical installations.

Frequently Asked Questions: Single-Phase Hybrid Inverters

What is a single-phase hybrid inverter?
A single-phase hybrid inverter is an all-in-one energy management system designed specifically for homes and small commercial properties connected to a standard UK single-phase electrical grid. Unlike traditional inverters that only convert solar power, a hybrid unit combines solar input, battery storage integration, and grid interaction into one device. It cleverly directs solar energy to power your home, charges your battery with any excess, and interacts with the National Grid when necessary.

Is a single-phase hybrid inverter right for my home?
The vast majority of UK residential properties have a single-phase electrical supply. If you are looking to install a new solar PV system with battery storage, or you want to upgrade your current setup to include battery storage, a single-phase hybrid inverter is the ideal choice. We stock highly capable models, such as the industry-leading Sunsynk Ecco range, which is perfect for maximizing self-consumption and lowering your energy bills.

What size single-phase inverter do I need?
The right size depends on the size of your solar panel array and your household's peak energy demands. We offer a wide range of capacities to suit any project:

  • 3.6kW to 5.0kW Inverters: (e.g., Sunsynk Ecco 3.6kW / 5.0kW) Excellent for standard UK homes with typical energy usage and a standard roof-sized solar array.
  • 7.0kW to 8.8kW Inverters: Ideal for larger homes or households with higher energy demands, such as those running EV chargers or heat pumps.
  • 10.0kW to 16.0kW Inverters: (e.g., Sunsynk Max 16.0kW) Perfect for large domestic properties or small commercial installations that require substantial energy flow and heavy battery charging capabilities.

Do these hybrid inverters work with battery storage?
Yes, battery integration is the primary feature of a hybrid inverter. All single-phase hybrid inverters in this collection are built to seamlessly integrate with compatible lithium battery storage systems. This allows you to store the free solar energy you generate during the day and use it during the evening or peak-rate hours, drastically reducing your reliance on the grid.

Can a single-phase hybrid inverter provide backup power during a power cut?
Yes, many of the models in this collection, notably the Sunsynk range, offer excellent backup functionality. Depending on the system configuration and wiring, these inverters can operate in off-grid or hybrid modes. In the event of a UK grid failure, a correctly installed hybrid inverter can isolate your home from the grid and continue to power your essential circuits using the energy stored in your batteries and generated by your solar panels.

Do I need permission from the DNO (Distribution Network Operator) to install one?
In the UK, if you are installing an inverter with a capacity of 3.68kW or under (like the Sunsynk Ecco 3.6kW), you can generally install it under the "G98" process, which only requires you to notify the DNO after installation. However, for inverters larger than 3.68kW per phase (such as 5.0kW, 8.8kW, or larger models), you must apply for "G99" permission from your local DNO before proceeding with the installation. Your certified solar installer will usually handle this application for you.
