myenergi Eddi Solar Diverter & Immersion Controller — Ireland 2026
Ireland's most popular solar diverter — intelligent, app-controlled and myenergi ecosystem aware
Ireland's most popular solar diverter. Can manage two heating loads in priority order — surplus goes to immersion first, remainder to a secondary load. Works with standard 3-pin Irish immersion thermostats. When combined with the myenergi Hub, shares real-time generation data with Zappi (EV charger) for whole-home solar coordination.

Key highlights
🇮🇪
Ireland's most popular diverter
The most widely installed solar diverter in Irish homes — proven in Irish conditions at scale, supported by most installers.
🔀
Two outputs — two heating loads
First priority goes to the immersion, then any remaining surplus goes to a secondary load (e.g. a heat pump element or underfloor heating).
📱
App control + boost schedule
Set timed boost to ensure hot water is ready when you need it — regardless of solar availability. Fully programmable via the myenergi app.

Turn your EV charger into a bookable Charging Hub. Set energy mode to Pure Solar — EV drivers can book your charger and charge on your renewable energy. No extra hardware.
The Eddi Solar Diverter & Immersion Controller is Step 4 of a complete Irish home energy system. You need solar panels, an inverter and a battery before it — and a heat pump or hot water cylinder after it to get the maximum return from every unit of solar energy generated.
Most popular Irish combination in 2026: LONGi or JinkoSolar panels + Huawei SUN2000 hybrid inverter + Huawei Luna2000 battery + FusionHome smart energy controller — installed by a SEAI-registered contractor.
🚗 Add an electric car — managed by your smart energy system
Smart energy management and an EV are made for each other. Your system already coordinates energy across your home — an EV adds a large flexible load that charges at exactly the right time: solar surplus, lowest tariff, or when your battery is full. See all 205+ EVs in the EV Vehicle Directory.

❓ Questions about the Eddi Solar Diverter & Immersion Controller
The myenergi Eddi Solar Diverter & Immersion Controller is available in Ireland for approximately €260 (Payback typically under 18 months for a 4kWp Irish home). Widely available — most Irish solar installers. For a typical Irish home with a 4kWp solar system, a solar diverter typically pays back within 10–18 months. Surplus solar that would be exported at the Clean Export Guarantee rate of €0.12–0.19/kWh is instead used for hot water — effectively saving €0.30–0.35/kWh (your avoided grid import rate). For a 4kWp system diverting ~1,400 kWh/year to the immersion, annual hot water savings are €420–490.
Widely available — most Irish solar installers. Always confirm the installer is familiar with the myenergi product and can provide full commissioning and after-sales support in Ireland.
Yes — the myenergi Eddi Solar Diverter & Immersion Controller works with any standard Irish hot water cylinder with an immersion heater element, regardless of whether it uses a 1kW, 2kW or 3kW element. It is compatible with all common Irish cylinder types — copper indirect cylinders, stainless steel cylinders, and thermal store cylinders — provided they have a standard 1¾" BSP immersion boss. If you have a combi boiler with no separate cylinder, a solar diverter is not applicable — you would need a hot water cylinder installed first. See the Hot Water Cylinder Directory →
Yes — the myenergi Eddi Solar Diverter & Immersion Controller uses a CT (current transformer) clamp sensor to detect surplus solar export and does not need to communicate with your inverter. It works with every inverter brand installed in Ireland — Huawei, Fronius, SolarEdge, Sungrow, SMA, Growatt, GoodWe and all others. There is no inverter compatibility concern; the diverter reads the electrical signal on your supply cable directly.
A solar diverter redirects surplus solar electricity — which would otherwise be exported at the CEG rate of €0.12–0.19/kWh — to your immersion heater. Since heating water electrically costs approximately €0.30–0.35/kWh from the grid, each unit of diverted solar effectively saves €0.30/kWh rather than earning €0.12–0.19/kWh on export. For a typical Irish home with a 4kWp solar system generating approximately 3,600 kWh/year, with around 1,200–1,800 kWh going to the immersion, annual hot water savings are €360–540. At €260 installed, payback is typically 12–18 months.
The Eddi itself is not directly grant-eligible, but it is frequently installed as part of a wider solar installation that includes the SEAI Solar PV Home Grant of up to €1,800. Some Irish solar installers include an Eddi in their system package quotes — the grant applies to the solar panels, inverter, mounting and labour (the system cost), and the Eddi can be added to the package. Ask your installer to include the Eddi in the system quote if you want the most seamless integration.
Yes — the Eddi works as a standalone solar diverter without any other myenergi products. It reads surplus solar via a wireless CT clamp sensor and diverts automatically. The myenergi Hub and Zappi are optional additions. The Hub simply adds whole-home coordination — so that Eddi and Zappi don't compete for the same surplus solar.
Smart energy management and heat pumps are complementary parts of the same home energy system. A heat pump heats your home and hot water; a HEMS controller (myenergi Hub, Huawei FusionHome or GivHub) decides when it runs based on solar generation, battery state and electricity tariff — reducing running costs by 15–30%. A smart thermostat (Tado V3+, Honeywell T6R) adds geofencing and room scheduling on top. The complete system flow: ☀️ solar panels generate electricity → ⚡ inverter converts it → 🔋 battery stores surplus → 🧠 HEMS schedules the heat pump → 🌡️ heat pump heats the home → 💧 hot water cylinder stores the heat. On a smart tariff the HEMS can also charge the battery at night rate (€0.08–0.12/kWh) to power the heat pump at off-peak hours rather than expensive peak rate — a significant additional saving on top of solar self-consumption. See the Heat Pump Directory →
The fastest wins in order of payback speed: (1) a solar diverter (€120–260, payback 10–18 months for any Irish home with solar panels), (2) a smart thermostat (€120–160, payback 4–6 months from heating savings), (3) an energy monitor (€35–95, often pays back from a single behavioural change identified). Together these three products can be installed for €300–500 and generate combined annual savings of €600–900 in a typical Irish home.
The SEAI Solar PV Home Grant (up to €1,800) covers the whole solar installation cost — panels, inverter, mounting and labour. Smart energy products like diverters and HEMS controllers are not separately grant-eligible, but they can be included in a solar system quote and the grant applied to the combined installation. Smart thermostats — Tado V3+ and Honeywell T6R — are SEAI registered products, which can be included in wider home energy upgrade grant applications. See seai.ie for current grant conditions.
