An energy management system (EMS, also energy manager) controls when which consumer receives solar electricity – hot water, heat pump, e-car, battery – and thus significantly raises self-consumption. In 2026, the Swiss Solar Manager is the best-selling manufacturer-independent solution; besides this, there are systems like my-PV (hot water focus), platforms like gridX, as well as the managers integrated into inverters from Fronius, SMA or Huawei. A separate EMS costs around CHF 800 as a device plus installation and is particularly worthwhile if you want to bring multiple controllable consumers from different manufacturers under one roof – it can be retrofitted to practically any system. Since 1 January 2026, the flexibility of your system legally belongs to you; an EMS makes it usable. (As of: September 2026)
Key points in brief
- An energy management system controls consumers – unlike the monitoring app, which only displays.
- Solar Manager (Swiss provider) is the best-known manufacturer-independent solution, in the medium price segment.
- my-PV is specialised in hot water (power-to-heat); gridX is the platform behind many brands.
- Fronius, SMA and Huawei bring their own energy managers – strong in their own ecosystem.
- A separate manager is particularly worthwhile for multiple controllable consumers from different manufacturers.
- Costs: integrated managers at no extra charge; a manufacturer-independent device like the Solar Manager Flux costs around CHF 760 to 850 in retail plus installation and subscription.
- New since 1 January 2026: your grid operator may curtail up to 3 % of your annual production without remuneration – more only by contract with remuneration (Art. 17c StromVG). An EMS brings the electricity into the house beforehand.
What is an energy management system – and what does it not do?
The law defines it soberly: intelligent control and regulation systems are devices with which the consumption, generation or storage of electricity is influenced remotely – «namely to optimise self-consumption» (Art. 17b StromVG). Swissolar summarises the four tasks of an EMS as follows: measuring energy flows, monitoring generation and consumption, controlling consumers (self-consumption, peak loads) and communicating with third parties, such as the utility. In a single-family home, this means: an energy management system is the control centre for your solar electricity. It knows how much the system is currently producing and how much the house is consuming, and distributes the surplus intelligently: first it covers the basic needs, then it heats up the hot water for example, charges the e-car or fills the battery – in an order that you determine. This way, more solar electricity ends up in your own house instead of in the grid for little money.
The distinction is important: an energy manager actively controls, a monitoring app only displays. Both are useful, but they are two different things. How to fundamentally increase self-consumption – with and without a manager – is dealt with in the article Optimise self-consumption.
Which energy management systems are relevant in 2026?
| Solution | Character (rough classification) |

How widespread the solutions are in Switzerland was surveyed by Swissolar for the first time in 2026: the Solar Manager is in first place – 64 percent of the member companies surveyed sell it –, around half each use the manufacturer's own systems from Fronius and Huawei. Often two solutions are combined: the integrated manager of the inverter for the system and battery, an overarching energy manager for the heat pump, wallbox and dynamic tariffs (Swissolar battery monitor 2026, as of: September 2026).
The great advantage of a manufacturer-independent solution like the Solar Manager: it brings devices of different brands together – inverter from A, heat pump from B, wallbox from C. The manufacturer's own managers from Fronius, SMA or Huawei, on the other hand, are strong if your components come from a single source anyway; then they often control their own ecosystem without additional costs. my-PV, in turn, is the obvious choice when it is primarily about hot water heating.
What does an energy management system cost in Switzerland?
Three items are decisive: the device, the installation by the specialist electrical company and any subscription fees. The range extends from «included for free» to a separate device in the distribution board:
| Solution | Device | Running costs | Installation |
|---|---|---|---|
| Integrated manager (Fronius Solar.web with Wattpilot/Ohmpilot, Huawei EMMA, SMA Home Manager) | included in the inverter ecosystem, sometimes accessories necessary (smart meter, heating element controller) | usually none | together with the solar system |
| Solar Manager Flux (CH, manufacturer-independent) | around CHF 760 to 850 (retail prices, September 2026) | Subscription CHF 44 (BASIC) or CHF 66 (PREMIUM) per year, first year included | Installation in the distributor, measuring point, cabling or relay to the consumers, configuration |
| my-PV (AC-THOR, hot water) | Controller plus heating element connection, price depending on power level | none | Specialist electrical company, usually together with the boiler |
As a guideline value for a retrofitted, manufacturer-independent EMS in a single-family home with two to three connected consumers, we reckon with around CHF 1,500 to 2,500 including device, installation and configuration – empirical value from our quotes, without obligation. Installed together with the solar system, the extra price is significantly lower because the measuring point and cabling are planned anyway. What the Solar Manager controls in detail and how we set it up is shown on the page Have Solar Manager installed.

What does it bring – and what has changed legally in 2026?
The Swiss Federal Office of Energy calculated it in the fact sheet «Photovoltaics self-consumption»: Without a battery and without controlled hot water, a solar system that produces 1.6 times the household demand typically reduces grid draw by slightly less than 40 %. If the hot water is targetedly charged via the heat pump in the early afternoon or PV-controlled, the grid draw drops considerably further – without additional investment. Exactly herein lies the conclusion of the SFOE: The most cost-effective measures use batteries that are present anyway – hot water cylinder, heat pump, e-car – and for this «a correspondingly intelligent regulation» is needed. The SFOE advises against electric heating elements that simply burn up surplus.
Since 1 January 2026, a second reason has been added. With the revised Electricity Supply Act, the flexibility – i.e. the controllability of draw, storage and feed-in – expressly belongs to you as the system operator (Art. 17c StromVG). The distribution grid operator may only curtail up to 3 % of the annual production at the connection point without your consent and without remuneration – in practice mostly as a fixed feed-in limitation to 70 % of the module power. Any further use requires a contract with remuneration; grid operators may continue to use existing ripple controls against remuneration until you prohibit this. For the EMS this means two things: it brings the midday surplus into the house before it is lost at the feed-in limit – and it is the technical prerequisite for marketing flexibility yourself later or using dynamic electricity tariffs. The marketing side is covered in Market battery flexibility; the data basis is provided by the smart meter, which the grid operators must have installed at 80 % of the measuring points by the end of 2027.

Can an energy management system be retrofitted?
Yes – with practically any existing solar system, and that is the most common case in our practice: the system is there, the heat pump or the e-car are added years later. Three things are needed: a measuring point for production and draw (interface of the inverter or a separate meter at the house connection), controllable consumers – heat pump with SG-Ready contact or manufacturer interface, wallbox with open interface, boiler via relay – and an internet connection. Old inverters without a data interface are no criterion for exclusion; then the EMS measures at the meter. It only becomes complex if neither cables nor radio links lead to a consumer. What can be achieved without a device – placing time windows for the boiler and heat pump in the midday hours – is described in Optimise self-consumption; that is the first, free stage, which the SFOE expressly recommends.
When is a separate energy management system worth it?
Not every system needs one. The honest rule of thumb:
A separate manager is worth it if you have multiple controllable consumers from different manufacturers – such as heat pump, e-car and battery, which do not all come from the same ecosystem. Then an independent control centre brings the greatest benefit because it orchestrates the interplay across brand boundaries. The interplay of battery and heat pump is dealt with in depth in the article Battery and heat pump.
A separate manager is worth it less often if your components already come from a single source (then the integrated manager is often sufficient) or if you only have a single controllable large consumer – for example just a wallbox. Then its own control is often sufficient; the distinction for this is drawn in the article Smart charging app.
The benefit is real: with good control, the proportion of self-used solar electricity can be noticeably raised – the magnitude from around a third to well over half is well documented. Whether the effort pays off for you depends on how many consumers you really coordinate.
We answer «Do I need an energy manager?» with a counter-question: How many large consumers do you want to control with the sun? Those who only have a wallbox often manage with its own function. But as soon as a heat pump, e-car and battery come together – and moreover from different manufacturers –, an independent control centre like the Solar Manager is worth its weight in gold. We like it because it works across brand boundaries; that fits our philosophy of choosing the best component for each task instead of taking everything from one brand. Where everything comes from one ecosystem, we consciously omit the additional manager – nobody has to pay twice for the same function.
Frequently asked questions
What is the difference between an energy manager and a monitoring app?
The energy manager actively controls which consumer gets solar electricity when – hot water, heat pump, e-car, battery. The monitoring app only displays what the system produces and consumes. The manager changes what happens, the app observes it. For a higher self-consumption, control is needed, not just viewing.
Is the Solar Manager a good choice?
For systems spanning different manufacturers, yes. The Solar Manager is a Swiss, manufacturer-independent energy manager in the medium price segment, which brings together inverters, heat pumps, wallboxes and batteries of various brands. Its advantage is exactly this independence – where everything comes from a single source, the integrated manager is often sufficient.
What alternatives to the Solar Manager are there?
Three directions: the manufacturer's own managers from Fronius, Huawei or SMA, if your components come from an ecosystem anyway; specialised solutions like my-PV for hot water; and open or platform-based systems like gridX, evcc or the OpenEMS integrated in Fenecon batteries. Which one fits is determined by the origin of your consumers and whether you want to control variable tariffs or a ZEV.
Does ecoEn install the Solar Manager?
Yes. We set up the Solar Manager across manufacturers – typically where a heat pump, wallbox and battery from different brands are to interact – and use the integrated managers in Fronius and Huawei systems if they are sufficient. Which variant is sensible for your house is clarified in the planning; what the installation includes is stated on the page Have Solar Manager installed, the introduction can be found on the page Smart Home & Energy management.
Do I even need a separate energy manager?
Not necessarily. It is particularly worthwhile if you want to coordinate multiple controllable large consumers from different manufacturers. If you only have a single consumer or a closed ecosystem, the built-in control is often sufficient. The honest answer depends on the number and origin of your consumers.
How much more self-consumption does an energy manager bring?
With good control, the self-used proportion of solar electricity can be noticeably raised – from roughly a third without control to well over half. The exact value depends on your consumers and your everyday life; a manager makes the sequence plannable, but does not replace the correct system dimensioning.
What does an energy management system cost?
Integrated managers from Fronius, SMA or Huawei are included in the inverter ecosystem. A manufacturer-independent device like the Solar Manager Flux costs around CHF 760 to 850 in Swiss retail, plus a subscription of CHF 44 or 66 per year (first year included) and installation by the specialist electrical company. Retrofitted, we expect around CHF 1,500 to 2,500 as a guideline value in a single-family home completely; together with the solar system significantly less.
Is an energy management system sensible?
As soon as you have at least two large, controllable consumers – heat pump, e-car, boiler, battery –, yes: the SFOE designates the controlled use of batteries that are present anyway, such as hot water and car battery, as the most cost-effective self-consumption measure. With just one wallbox, its own surplus function is usually sufficient. Since 2026, there is the addition that the grid operator may curtail up to 3 % of your production – electricity that an EMS can utilise in the house beforehand.
Can I retrofit an energy management system?
Yes, with practically any existing system. Needed are a measuring point for production and draw (inverter interface or meter at the house connection), controllable consumers (SG-Ready heat pump, wallbox with open interface, boiler via relay) and internet. The effort depends on whether cables or a radio connection have to be laid to the consumers.
Which energy management system is the best?
There is no single best one – the choice depends on your components. If the inverter, wallbox and battery come from one ecosystem, the integrated manager is often the best choice because it costs nothing extra. With mixed manufacturers, an independent system like the Solar Manager is at an advantage; important are open interfaces (SG-Ready, Modbus, OCPP), suitability for dynamic tariffs and Swiss support.
