The Benefits of Add-ons for Your Solar System

Investing in solar panels in Northern Ireland is a fantastic step towards reducing your energy costs and lowering your carbon footprint. However, to truly maximise the benefits of your solar installation, consider incorporating add-ons like an immersion heater controller, a battery storage system, and an EV charger. These additions can significantly enhance your system's efficiency and savings. Let's delve into the specifics of each add-on and how they can benefit homeowners in Northern Ireland.


1. Immersion Heater Controller: MyEnergi Eddi

An immersion heater controller, such as the MyEnergi Eddi, is an excellent addition to your solar system. This device redirects excess solar power to heat the water in your tank, ensuring that no energy goes to waste. Here are the key benefits:


·         Energy Efficiency: By using surplus solar energy to heat your water, you reduce the need for electricity or oil to do the same job. This increases the overall efficiency of your solar system.

·         Cost Savings: Heating water can account for a significant portion of your energy bill. With the Eddi, you can utilise free solar power, leading to substantial savings.

·         Year-Round Benefits: The Eddi works all year round, but you will see the most benefit from March to October due to longer daylight hours. During these months, there is more excess energy to divert to heating water. In winter your water will already be warm due to your central heating being switch on.

·         Compatibility: The Eddi works with most homes that have an immersion heater and a water tank, particularly those with oil central heating systems.


At an additional cost of £600 (with 0% VAT), the MyEnergi Eddi is a valuable investment for enhancing your solar system's performance.


2. Battery Storage: SolarEdge and Duracell Options

Home storage batteries allow you to store excess solar energy for use during times when your panels aren't generating power, such as dull days or at night. We offer two robust options:


SolarEdge 10kw battery

SolarEdge Energy Bank (10kW)

·         Cost: £6,800 (with 0% VAT)

·         Compatibility: This DC battery is compatible only with a SolarEdge HD wave, contact us for more details. 

·         Benefits: Storing energy in a high-capacity battery ensures that you can use your solar power whenever you need it, reducing reliance on the grid and increasing energy independence.


Duracell Energy Home Battery (5kW)

Duracell Energy solar battery

·         Cost: £2,150 - £3,950 (with 0% VAT), depending on system amendments.

·         Scalability: Add another 5kW battery for an additional £1,800, making it a 10kW system.

·         Benefits: The Duracell solar battery is compatible with the Solis hybrid inverter, which can be implemented as a DC coupled or AC coupled storage system (depending on your existing solar set up, contact us to discuss).


Both options provide significant benefits, including enhanced energy independence, increased savings, and better utilisation of your solar system. Additionally, you can charge from the grid during the winter on an economy tariff to save even more.


 3. EV Charger: MyEnergi Zappi

For electric vehicle owners, the MyEnergi Zappi car charger is an ideal addition. It offers several advantages over standard EV chargers:

Zappi car charger

·         Flexible Charging Modes: The Zappi car charger allows you to trickle charge your car using only excess solar energy, or switch to fast charging using grid power when needed.

·         Cost Savings: By utilising surplus solar power, you reduce the cost of charging your vehicle.

·         Eco-Friendly: Charging your EV with solar energy further reduces your carbon footprint, making your transportation as green as your home energy use.

·         Pricing: The MyEnergi Zappi car charger is priced at £1,150 plus 20% VAT.



Boost your solar system with these add-ons:

  • MyEnergi Eddi Hot Water Diverter: Use excess solar energy to heat water.

  • SolarEdge and Duracell Solar Battery: Store surplus energy for later use.

  • MyEnergi Zappi EV Charger: Power your electric vehicle with solar energy.

These add-ons ensure that you make the most of the solar energy you generate, reducing reliance on the grid and maximising your investment.
