SMA Energy System Large Scale

Store solar power and use it broadly

Sustainable investing and maximum profit

With the SMA Energy System Large Scale, you can store solar power. This enables you to manage peaks in demand, stabilize grid voltage and reduce energy costs considerably.

Secure investment in emerging technology

The SMA Sunny Central Storage UP battery storage system will increase the efficiency of your PV power plant. At the same time, battery storage systems perform important grid management functions. Grid frequency fluctuations are avoided thanks to smart plant control with the Power Plant Manager and grid voltage is restored in seconds. Sudden, costly increases in power consumption are prevented by means of load shifting. At night, the energy storage system is charged cost-effectively to cover consumption during the day. SMA storage solutions offer you further potential for maximizing the profit from your sustainable investment.

Benefits

Supplies renewable energy 24/7

Compensates for load peaks with stored power

High flexibility through extremely fast charging/discharging

Additional profit maximization

AC-coupled systems

AC-coupled systems are ideal when existing PV power plants are retrofitted with battery-storage systems. But the AC-coupled battery-storage system also optimizes load management in new installations. It stores excess energy and makes it available again within milliseconds.

The system in detail

The SMA Energy System Large Scale allows you to store electricity that you can then sell as needed.

PV modules
The PV modules generate direct current from incoming sunlight.
Sunny Central UP
The SMA Sunny Central UP central inverter is the core of your SMA Energy System Large Scale with a centralized system layout. It converts the direct current generated by the PV system into alternating current to be able to feed this into the grid.
Sunny Central Storage UP
The SMA Sunny Central Storage UP battery inverter temporarily stores the surplus solar power in the battery. It performs various grid support functions including frequency, voltage and reactive power control, and it can carry out a black start in the event that the grid collapses.
SMA Power Plant Manager
The SMA Power Plant Manager monitors and manages the energy flows between producers, consumers and the utility grid. It secures need-based energy generation, helps stabilize the utility grid and contributes to optimal energy marketing.
Battery
The battery efficiently stores the solar power temporarily and makes it available again as required. This means that you can use solar power around the clock and feed it into the grid as necessary.
SMA Monitoring
With SMA Sunny Portal powered by ennexOS, you can keep track of current and historical system data at all times. This also enables you to see exactly how much electricity you could still sell.

How it works

The SMA Power Plant Manager ensures that surplus solar energy is stored in the battery-storage system via the SMA Sunny Central Storage UP battery inverter. Alternating current is converted into direct current.

DC-coupled systems

DC-coupled systems are ideally suited for the new installation of large PV power plants with Sunny Central 1,500 V technology. Here, the battery and PV array are connected to the central inverter on the DC side, and excess solar energy is fed directly into the battery in a particularly efficient manner.
