Renewables Distribution Boards for Solar, EV and Heat Pump Systems

Integrated, Compliant and Installer-Ready Electrical Distribution Solutions

Eco-ESS Renewables Distribution Boards deliver power distribution for solar PV systems, EV charge points and heat pump installations in a single, integrated panel. By combining all these functions, installers can simplify circuit separation and reduce on-site wiring. At the same time, the boards improve electrical safety and help installers follow current wiring regulations for multi-technology, renewable systems.

Whether the project includes one renewable technology or a combination of PV, EV charging and heat pumps, these boards provide a clear and organised system layout. As a result, installers get defined circuit allocation, better load management, and easier inspection and testing. Moreover, the pre-configured design reduces installation time, lowers the risk of wiring errors, and speeds up commissioning.

In the end, Eco-ESS boards give installers a practical and compliant solution, allowing them to deliver safe, neat, and future-ready renewable energy systems while keeping the installation process simple and efficient.


What Is a Renewables Distribution Board?

A Renewables Distribution Board (RDB) is a purpose-built electrical assembly that manages and protects renewable energy installations. It not only distributes incoming supply power efficiently to all connected renewable loads but also houses essential protective devices, including MCBs, RCDs, RCBOs and isolators.

In addition, the RDB provides surge protection and maintains proper circuit segregation, while streamlining wiring for solar PV systems, EV charge points and heat pump circuits. As a result, the RDB acts as the central hub for electrical protection and distribution, helping installers deliver safe, compliant and well-organised systems across multiple renewable technologies.

One board. Three systems. Zero hassle.

Why Choose a Combined Renewables Distribution Board?

Traditionally, installers use separate distribution boards for different renewable technologies. For example, they install:

  • Solar PV protection and array isolation
  • EV charger circuits with RCD protection
  • Heat pump distribution with correctly configured RCDs and MCBs

However, this approach quickly increases complexity and installation time. In contrast, a combined Renewables Distribution Board (RDB) brings all these systems together into a single enclosure and simplifies the entire process.

As a result, installers can:

  • Complete installations faster and reduce labour, since circuits come pre-organised
  • Manage cables more effectively, creating a safer and tidier setup
  • Apply integrated RCD and MCB protection tailored to each technology
  • Allow for future upgrades, keeping installations flexible
  • Achieve a cleaner, more professional on-site appearance
  • Reduce overall project costs compared to multiple separate units

Furthermore, this integrated solution suits modern renewable installations perfectly. For instance, installers can combine solar PV, battery storage, EV charging and heat pumps within one streamlined system.

Consequently, installers deliver a more efficient, compliant and inspection-ready setup while reducing both installation time and complexity.

Frequently Asked Questions

Yes — combined distribution boards are engineered with segregated ways and protective device slots to safely distribute power and isolate each technology independently. 

Yes. Boards are typically configured with Type 2 SPD accommodation to protect against transient surges on renewables and EV circuits. 

Heat pumps and EV chargers require correct RCD protection (Type A minimum, Type B where DC leakage may be present).

Yes — option boards can be supplied in IP-rated enclosures suitable for garages, utility spaces or external locations. Compliance with external installation standards (e.g., IP and mechanical protection) is determined on a per-model basis.
