Battery Storage Solutions

The general philosophy of solar battery storage systems revolves around harnessing, storing, and efficiently utilising renewable energy generated from solar panels.

By incorporating these principles, solar battery storage systems offer a comprehensive solution for efficient, sustainable, and cost-effective energy management.

What type of battery storage solution is right for you?

There are essentially two types of solutions, each with its own set of advantages and disadvantages. Both options offer good reasons to be considered and can be beneficial depending on specific needs and circumstances.

AC Coupled PV Inverters

  • System Design and Flexibility: AC coupled PV systems use separate inverters for solar panels and battery storage, allowing easy integration with existing solar setups and offering flexibility in system sizing and future upgrades.
  • Compatibility and Benefits: These systems support the addition of battery storage to any brand of existing solar inverter, preserving benefits like Feed-in Tariff (FIT) payments, enabling emergency backup power, and facilitating participation in energy markets.
  • Considerations and Trade-offs: While offering significant advantages, AC coupled systems may involve higher installation costs, require more space, and experience some efficiency loss due to multiple power conversions.

 

While the example features a Tesla battery, we also work with a wide range of reputable battery brands such as Pylontech, Solax, and BYD. This flexibility allows us to tailor energy storage solutions to meet the specific requirements of our customers, ensuring compatibility with various system configurations and maximising performance.

DC-coupled Hybrid PV Inverters

  • Hybrid PV systems ensure continuous power supply by combining solar panels, a hybrid inverter, and battery storage, offering both grid-tied and off-grid benefits.
  • Hybrid inverters enhance energy independence and cost-efficiency by storing excess solar energy, reducing grid reliance, and integrating multiple functions into one device.
  • Intelligent energy management allows hybrid inverters to automatically switch between solar, battery, and grid power, optimising energy use and adapting to different needs.

 

The example system shown comprises of four Solax hybrid inverters, each with a capacity of 15 kW, delivering a total inverter output of 60 kW. Each inverter is connected to four Solax batteries, with each battery offering 5.8 kWh of storage. Altogether, the system provides a total battery storage capacity of 92.8 kWh. This configuration ensures efficient energy conversion, storage, and management, making it well-suited for medium to large-scale hybrid solar applications that demand high power output and significant energy storage.
