Our modular electricity storage solutions are as diverse and varied as the needs of our customers.

No two systems are the same - the only and at the same time most important thing they have in common is that they all produce their own electricity - store it - and increase their own demand quota and degree of independence.

We take pleasure in designing, selling and installing our systems - with the customer's benefit always at the centre of our efforts.

Project AB from Möriken AG

With the realisation of its own solar storage system, AB from Möriken used every m2 of its two roof surfaces to achieve a total rated output of 17.01kWp.

A total of 42 monocrystalline panels with 405W each were installed, as well as 2 x 10kWh electricity storage units - a total of 20kWh.

We assume that family AB will produce approx. 16`783kWh of solar electricity. This corresponds to about 1.2 times their own electricity needs.

Of course, the system does not produce in a linear fashion to consumption in relation to the seasons and hours of sunshine - but with the Swaytronic electricity storage system, the production curve can be smoothed considerably and in this case a self-consumption rate of almost 60% can be achieved.

Between April and October, we assume a degree of independence of approx. 70-80%.

Our SMART hybrid inverter with emergency power function

In this project, we used our 12kW SMART hybrid inverter, which optimally coordinates the three orientations east-west and south and distributes the power 3-phase and bidirectionally.

In this case, the setup provides for the following priorities with regard to electricity production and its distribution:

1. the solar power covers the current consumption

2. the excess production is stored in the battery

3. the excess production is fed back into the grid.

As soon as the solar electricity production no longer covers the consumption, as well as in the evening at night and early in the morning - or in bad weather, the electricity demand is covered as follows:

1. the battery supplies the entire household load up to the defined state of charge

2. mains electricity is only switched on when the battery is exhausted - and no solar electricity is available.

The inverter perfectly coordinates the production, storage, sale and purchase of grid electricity.

The Swaytronic Wall – Power Storage

In this project, 2 10 kWh wall-mounted storage batteries were used, which were connected in parallel. Each battery module has its own BMS, i.e. there is permanent cell and battery pack monitoring.

The wall storage modules can be expanded modularly by up to a total of 16 units. These are permanently connected to each other and to the SMART Hybrid Inverter.

The BA family can thus significantly flatten the solar power production curve and noticeably reduce the amount of electricity drawn from the grid.

The two modules are in permanent emergency power mode, i.e. if the mains power fails and no solar power is being produced, the battery modules switch on within 4ms to guarantee an uninterrupted power supply.

The modules each provide up to 4.8kW of permanent discharge, which means that we have up to 9.6kW available in parallel mode.

This means that there is enough energy available for emergency power operation as well as for the daily discharge of the solar storage unit to supply all or selected consumers in the house.

Installation of the solar system

The system was installed in cooperation with the company WYSolar GmbH from Muhen. WYSolar took over the planning, implementation and commissioning of the solar modules.

A total of 42 modules of 405W each were installed. Three strings were created, one string for each orientation (east-west-south).

Electrical adaptations AC

The electrical adaptations were realised in cooperation with the company Elektro Würgler AG from Niederlenz.

The electricians adapted the house installation in such a way that the AC line runs directly through our inverter after the regenerative meter in order to be able to switch the house over to emergency power in the event of a mains failure.

Layout - Wiring diagram

By means of a layout or active circuit diagram, we depict the function and configuration of the system in combination with the solar modules, the fuses and the connectivity.

The customer thus has a clear overview of the planned or installed modules. The solar installer as well as we thus create a clear basis of responsibilities and ensure the function in advance by means of the active circuit diagram.

Project JS from Staufen AG

In this no less exciting project, we were allowed to "upgrade" an existing solar system, so to speak.

JS had already had a solar system with almost 11kWp installed 10 years ago. So it was time to add a battery storage system and make his house "emergency power-proof".

Thanks to the good cooperation and support of the customer JS, the solution was quickly designed and installed. It took less than 8 weeks from placing the order to installation and commissioning.

With this grateful reference example, we would like to go into more detail about the installed "upgrade".

System description – Solar/inverter

The existing SMA inverter was replaced with a SWAYTRONIC 10KW SMART-Hybrid Inverter 3PH - an all-in-one device with emergency power function.

The three PV strings were taken over and additionally protected against overvoltage and overcurrent by means of our PV combiner box.

The bi-directional and hybrid inverter used with a PV input power of 13kWp perfectly covers the performance of the 11kWp system and still has room for improvement - so that the unit is not also operated at full power.

System description – battery storage

The customer opted for a SWAYTRONIC 10kWh wall-mounted M electricity storage unit. Our wall-mounted electricity storage units can be extended to 16 modules in parallel operation.

In this project, it was already planned to simply add an additional battery module if required. The installation can accommodate this with only minor adjustments, as the back-up fuse and cabling already provide for this.

The battery module operates with 51.2V DC and delivers up to 7.68kW power from the battery. The module monitors all relevant battery data in live mode and transmits it to the inverter to monitor the function and safety at any time.

Increasing self-consumption and the degree of independence...

With the new solar storage system from Swaytronic, the customer JS consumes significantly more of the electricity he produces himself, feeds less back into the grid - and no longer buys electricity on many days between April and October. The battery storage system flattens the curve production VS. Consumption, so that a maximum of self-consumption is achieved. In the event of a grid failure, the battery automatically switches on within 4ms and guarantees an uninterrupted power supply.

Eine Wandvoll Speicher

Bei dieser Anlage handelt es sich um einen Hausspeicher mit einer Kapazität von 85.98kWh. Erreicht wird dies mit 6Stk. Swaytronic Wandspeicher Module, modular verschaltet - die Leistungsaufnahme erfolgt im parallelen Betrieb aller Module. Es handelt sich ausserdem um ein Low-Voltage System.

Steuerung ab bereits einem SSHWR

Bereits ab einem SMART-Hybrid WR lassen sich bis zu 16 Batteriemodule steuern. In diesem Fall und Projekt 6Stk. mit insgesamt 85.98kWh Speicher.

Kompakt und Plug & Play

Eine Hausspeicher-Anlage mit 10.14kWp Solar - und 15kWh Solarspeicher mit Notstromfunktion.

Im Cabinet

Wir haben 4-Rackmodule à je 5kWh verbaut. Die Cabinet-Lösung bietet einen IP65-Schutz mit Air-Condition System und eignet sich vor allem für Firmen und Anwender mit Standorte in kalten, warmen oder wechselnder Umgebung. Der Speicherinhalt je Cabinet kann auf bis zu 40kWh inkl. Wechselrichter ausgebaut werden.

Modularität ist der Schlüssel

Auch die Cabinets können aufbauen und in paralleler Verschaltung fast beliebig erweitert werden. Hermetisch abgeriegelt und klimatisiert sorgen die vollautomatischen Systeme stets für den besten Wirkungsgrad.

20kWh - der Hausstandart

Die meist gewählte Speicherkapazität liegt aktuell bei 20kWh, hier umgesetzt mit unseren Pro-Module à je 5kWh. Die Solaranlage umfasst 13.2kWp.

30kWh - Mehr Speicher

Wir sind flexibel und modular - die Wunschgrösse der Speicherkapazität kann auf 3 verschieden Arten erreicht werden. In dieser Kundenlösung haben wir 3 Wandmodule mit 10kWh verbaut. Die Batteriespeicher befinden sich bei diesem Kunden in einem anderen Raum.

Unsere Rackmodule 4.8kWh

Einen Speicher-Turm, oder anders gesagt - einen Turm von einem Speicher durften wir in Ehrendingen AG bauen. Der Kunde wünschte eine modulare und platzsparende Lösung, welche auf bis zu 16 Batteriemodule erweiterbar ist.

20kWh - der Klassiker

Auch hier durften wir 20kWh verbauen, die Kapazität der Solaranlage beträgt 15.1kWp. Bis zu 15.6kWp Solar und bis zu 16 - Batteriemodule können wir mit nur einem SMART-Hybrid WR realisieren.

30kWh - passgenau

Mit unserem flexiblen Systemen fügen wir uns nahtlos in bestehende Technikräume ein, die Batterien können sowohl an der Wand oder wie bei diesem Projekt auch gestapelt werden.

Kompakt und sauber

Ein Hoch auf unsere Partner im AC- und DC Bereich, wir freuen uns unseren Kunden saubere und funktionelle Installationen zu übergeben - in diesem Fall mit 20kWh Speicher und 11.34kWp Solaranlage.

Zwei und Zwei

Hie und da erfordern die Solaranlagen, in diesem Bsp. mit 24.6kWp, die modulare Erweiterung mit Wechselrichtern - der Vorteil, mit jedem zusätzlichen WR verdoppeln sich auch die entsprechenden Leistungen. Das System kann im "Parallelmodus" als ein System betrieben werden, damit die Solarproduktion und der Speicher als Kumulation zur Verfügung stehen.
