Photovoltaics: make the most of solar energy
More self-consumption, lower costs with intelligent energy management.
How to get the most out of your PV system
LOXONE measures generation and consumption, decides with foresight what pays off right now – using, storing or feeding in – and controls your consumers on this basis, from the heat pump to the electric car.
PV system with energy management: the benefits
Your investment pays off faster
Large consumers run automatically when there’s enough of your own solar power. This lowers your electricity costs and gets more out of your system.
Surplus is put to good use
Instead of flowing inefficiently into the grid, your surplus automatically goes where you need it – to devices and batteries, according to your priorities and the PV production forecast.
No overload, no costly peaks
When several large consumers run at the same time, LOXONE regulates the load automatically. At home, this protects against overload; in a business, it prevents costly consumption peaks.
Your electric car charges automatically with solar power
The LOXONE Wallbox charges with your PV surplus or with cheap electricity from your dynamic electricity tariff. This makes driving cheaper and makes optimal use of your PV system.
Everything at a glance
In the App, you can see generation, consumption and storage in real time and set your own priorities. You are notified immediately of any deviations or technical problems – increasing safety and reliability.
What you need
PV energy management also works with your existing system. The Miniserver integrates common inverters, batteries and devices – all you need are a few LOXONE components and setup by a certified LOXONE Partner.
Miniserver
The control center for your entire building: from lighting and shading to energy management.
Energy Meter & software meter blocks
Record all energy flows in real time – the basis for any control.
Wallbox
Charges your electric car specifically with your solar surplus or with cheap electricity from your dynamic electricity tariff.
Modbus Extension (optional)
Only needed for devices connected via Modbus RTU. The Miniserver already reaches many inverters and meters directly via Modbus TCP.
Retrofit e-mobility
Everything for charging your electric car: from the control to the Wallbox – retrofitted wirelessly, without any alterations.
An open system for your PV technology.
Inverters and batteries from common manufacturers such as Fronius, SMA, Kostal or Huawei can be integrated easily. You can find the complete, up-to-date list in the LOXONE Library.
FAQs
What is an energy management system for photovoltaics?
An energy management system for photovoltaics is a control system that automatically directs self-generated solar power to where it can be used most sensibly – instead of feeding it unused into the grid. It continuously measures how much power is generated and consumed, and switches consumers such as the heat pump, hot water or Wallbox exactly when solar power is available. This increases self-consumption and lowers electricity costs.
Photovoltaics is only one part of it: LOXONE controls energy management throughout the building and connects it with the entire building automation.
Does it work with my existing PV system?
Yes, it can easily be retrofitted. You can also integrate a PV system that is already installed – so you don’t need to have planned LOXONE in from the start. The Miniserver and the necessary components are added afterwards, and your system keeps running in the meantime. A certified LOXONE Partner checks in advance whether your inverter supports a suitable protocol and sets everything up.
Which inverters is LOXONE compatible with?
With most common models. Some, such as those from Fronius, are supported directly; many others like SMA, Kostal, Huawei or SolarEdge can be integrated via the open Modbus standard. You can see whether your model is included and how it is connected in the LOXONE Library.
Can I charge my electric car with my PV system?
Yes, with the LOXONE Wallbox you can charge your electric car specifically with your PV surplus (from as little as 1.38 kW) or with cheap electricity from your dynamic electricity tariff. Based on the presets, LOXONE automatically decides whether the solar power is better used for the car, other consumers or the battery.
Is solar energy management worth it even without a battery?
Yes, even without a battery you use more of your solar power, because the heat pump, hot water or Wallbox run automatically when the sun is shining. Without a battery, however, you can only use the power that is needed at that moment – the rest goes into the grid. A battery closes exactly this gap: it stores the surplus until you need it.
Is PV control also worthwhile in winter?
Yes, even though the yield is lower. A PV system still delivers a relevant share of its annual yield in winter, and that’s exactly when LOXONE uses every kilowatt hour specifically for heating and hot water.Â
How does LOXONE know the weather forecast?
Via the LOXONE Weather Service and the PV production forecast: the Weather Service delivers location-specific forecast data for up to 66 hours in advance directly to your Miniserver. Based on this, the PV production forecast calculates how much power your system is expected to produce over the next 72 hours. This way, the system knows when storing or using directly pays off. The Miniserver needs an internet connection for this.
