The sonnenPro EMS automatically optimizes
PV and storage are a strong start. You get the most benefit when generation, storage, and consumers work together intelligently – and you actively manage peak loads. The sonnenPro EMS automatically optimizes the sonnenPro Compact and gets the most out of your energy: reduce peak loads, make better use of PV power, control consumers, and procure energy at optimized prices.
For the smartest use of your energy.


sonnen's Experience in Commercial & Industrial
Frequently Asked Questions
No. PV self-consumption is often the most effective lever. However, depending on the load profile and electricity tariff model, sonnenPro Compact can also be beneficial without PV – for example, to relieve the grid connection (e.g., for charging infrastructure) or to reduce grid fees through, for example, atypical grid usage.
Yes. The sonnenPro Compact is suitable for indoor and outdoor installation with an IP55 protection rating. Prerequisites include a solid, suitable surface and good accessibility for installation and service. No additional roofing is required.
The design depends on your generation and load profile, the application (e.g., peak shaving, PV self-consumption optimization, load management), and the grid situation. After a non-binding initial consultation, our experts can determine the best and most economical battery storage size for you through a thorough simulation, based on your individual data (e.g., load profile data and electricity price information, etc.).
Yes. With the optional sonnenPro Backup (Backup Box), the sonnenPro Compact is emergency-power capable. In the event of a power outage, the system automatically switches to emergency power mode – with a switchover time of ≤ 20 ms.
For the sonnenPro Compact, you receive a 10-year product warranty on all components and a 5-year warranty on the inverter. The guaranteed storage capacity of the modules is at least 60 percent after 10 years or 8,000 charging cycles. Detailed information can be found in our sonnenPro Manufacturer's Warranty.
No. The sonnenPro Compact is a fully pre-configured system available in one unit size. For more capacity and power, up to 10 systems can be cascaded – including at a later date, so the system grows with your needs. The emergency power function with sonnenPro Backup is only available for a single system, not for a cascade.
Unfortunately, a general statement about the profitability of battery storage systems is not possible, as this depends heavily on individual circumstances (load profile, electricity tariff, etc.). Typically, the payback period for most customers is between 3 and 8 years. We can provide a precise assessment for your individual situation through a thorough economic viability calculation, including simulation. Please get in touch with us for more information.
