Battery storage - S³ SmartSolarStorage

Make your home or SME self-sufficient with the S³ Smart Solar Storage. Store up your extra solar energy during the day, then use it in the evening.

  • Energy storage in innovative lithium battery or environment-friendly salt water battery
  • Intelligent and automatic
  • Easy installation and integration (plug & play)
  • Increases your independence in case of power failure (back-up)
  • 230V AC-coupled
  • Modular: Expand the S³ with extra modules to a maximum storage capacity of ±18kWh. Still not enough? Then just install an extra S³
  • Easily monitoring online or via your smartphone.

From 30% to 70% own energy supply

The S³ Smart Solar Storage buffers your solar electricity in a battery  instead of injecting your surplus solar energy into the distribution grid. As soon as your self-generated energy is no longer enough to power your devices, the S³ jumps in. The energy stored in the battery is then fed back into your own electricity grid via the integrated converter. If your battery is empty, the distribution grid will still help out until the next sunny day. Battery storage increases your private energy supply from 30% to 70%. 

With the S³ you also increase your independence in the event of a power outage.
Freezer, refrigerator, PC, CH pump, ... continue to function via the integrated emergency power functionality (No-Break).

How much autonomy do I have with a 6.4kWh battery capacity?
In the winter mode (battery always fully charged) and 500W of consumption (e.g. freezer, CH pump and several energy-saving lamps), you’ll have an autonomy of around 10 hours.

Batteries

A battery is an essential part of a self-consumption system and we recommend choosing a lithium battery for this. Alternatively, you could opt for an environment-friendly salt water battery. Studies have shown that for an average home (consumption ± 5000kWh) a ratio of battery storage/consumption of 1.25kWh/1MWh is regarded as optimal.  

The modular lithium battery from Pylontech is the ideal solution for this; each module has a nominal capacity of 2.4 kWh and up to a maximum of 8 modules can be connected in parallel (useful capacity 17.6 kWh). 

Greenrock salt water batteries have a nominal capacity of 2.7kWh and available energy of 2.5kWh at a charge and discharge current of 5A (240W). The stacks can be connected in parallel almost without any limit.

Various systems

With our years of experience, we have devised a number of standard battery storage systems for our customers. Of course, we can develop a custom system in collaboration with the customer.

All our standard systems work in parallel with your home system, and a single-phase (1P) system can be connected to a single-phase or three-phase mains connection.

  • 3kVA (1P) inverter including a lithium battery of 4.8kWh or 7.2kWh 
  • 5kVA (1P) inverter with MPPT solar charger of 5.8kWp including a lithium battery of 9.6kWh 

You can download more information and prices for each of these systems below.
