Inverters & Battery Storage

Compare the main systems we can discuss

There is no single “best” inverter or battery for every property. Roof layout, energy use, backup requirements, available space and future plans all affect which system makes the most sense, so we talk through the right manufacturer for the individual job.

Hybrid inverter + battery

SolaX

Best for flexibility

A strong all-round option for domestic solar and battery installs, especially where future expansion and backup power are important.

Pros

  • Good range of hybrid inverter sizes for typical domestic installs
  • Modular battery options make it easier to size a system properly
  • Strong monitoring and smart control features
  • Good option where backup and future expansion matter

Considerations

  • Best results usually come from keeping the system within the SolaX ecosystem
  • The larger feature set means setup and design should be planned properly
  • Expansion still depends on using the correct compatible battery modules

String inverter + hybrid options

Solis

Best for straightforward systems

A well-known inverter brand that suits simple solar installs as well as many hybrid battery-ready systems, often at a sensible price point.

Pros

  • Strong reputation in the inverter market
  • Good value for straightforward solar and solar-plus-storage systems
  • Wide choice of single-phase options
  • Often a practical choice where customers want solid performance without overcomplicating things

Considerations

  • Battery offering is less of a single closed ecosystem than some rival brands
  • Monitoring and smart-home feel can seem simpler than premium systems
  • Compatibility needs checking carefully if mixing with third-party storage

Battery storage + home energy system

EcoFlow

Best for app-led storage

EcoFlow is attractive where the customer wants a modern, app-focused battery system with a strong emphasis on storage, backup and home energy control.

Pros

  • Clean, modern battery-led product range
  • Good focus on backup power and smart control
  • App experience is a big selling point
  • Can appeal to customers who want a more lifestyle-led energy product

Considerations

  • Not always the first choice for every traditional roof-mounted solar job
  • System design and compatibility should be checked carefully around the full install
  • Some customers may prefer a longer-established solar-specific ecosystem

Optimised solar + battery ecosystem

SolarEdge

Best for complex roofs

A strong option where shading, different roof elevations or panel-level monitoring are important, with the inverter and optimisers working as one system.

Pros

  • Panel-level optimisation helps with shading and roof complexity
  • Detailed monitoring down to panel level
  • Strong single-ecosystem energy management
  • Often a good fit for more awkward roof layouts

Considerations

  • Requires additional roof-mounted optimisers
  • Usually makes most sense when kept within the SolarEdge ecosystem
  • Can work out more premium in cost than straightforward string systems

All-in-one inverter + battery platform

Sigenergy

Best for premium smart systems

Sigenergy is a more premium, design-led option aimed at customers who want a sleek all-in-one system with advanced energy management and future-ready features.

Pros

  • Very clean all-in-one appearance
  • Strong smart-home and app control feel
  • Designed with expansion and advanced energy management in mind
  • Appeals to customers wanting a modern premium system

Considerations

  • Generally a more premium option
  • Best suited where the customer values the full ecosystem rather than just lowest cost
  • Final design needs careful planning to get the most from the platform

Best for storage-focused homes

AlphaESS suits customers who are mainly focused on battery storage and home energy control, with solar forming part of a broader storage-led system.

Pros

  • Strong focus on home battery storage
  • Suitable for customers who want more than just a basic solar install
  • Integrated monitoring and energy management
  • Can work well where self-consumption and storage are the main priority

Considerations

  • Needs the right application to show its strengths
  • Product selection and compatibility still need checking carefully
  • May not be the simplest route for very straightforward solar-only installs

Pros
