Integrate PV systems more quickly and easily into the AC home grid

As an installer, you can use the "Wattster" energy management system to connect classic PV systems from 1kW to 70kW to existing lines. Without interfering with the existing electrical system. This saves time and effort. Including your customers. In short: Plug & Play for PV professionals.

Half hour instead of half day

As an installer, do you want to integrate classic solar systems into the AC grid in less than 30 minutes? With Wattster, it's possible. The power management ensures non-invasive integration into the existing AC final circuit. The Wattster connected to the inverter continuously provides protection against an overload of the feed-in line and – if desired as a self-consumption system – also ensures that the zero feed-in is maintained. In this way, it will be possible to feed locally generated electricity far beyond the previous limits of plug-in solar solutions in a safe and standard-compliant manner.

There is no need to lay the AC and RS485 cables to the grid feed-in point, which is often very time-consuming and sometimes impossible, and – as a rule – also to replace the meter (only in the case of zero feed-in).

Smart IoT for green energy

Connected to the inverter, Wattster regulates the feed into an existing line thanks to SIMPLUG technology. This ensures overload protection at all times in the event of a feed behind the fuse.

The AC connection to the domestic grid can be implemented either with CE plugs (1- or 3-phase) or as wiring in sub-distribution boxes or directly at the grid feed-in point.

There is no need to lay an AC cable from the inverter to the grid feed-in point or RS485 cabling to the energy meter. The bridge, a wireless energy monitor developed by Wattando, provides the necessary data from the domestic grid.

The abstract sketch schematically illustrates how Wattando's Wattster energy management system works. The solar modules are connected to the inverter. A battery storage can optionally be added to the inverter. The Wattster box is simply inserted non-invasively between the inverter and the house circuit. This allows the electricity to enter the house circuit without having to convert the electricity meter or lay new cables.

Wattster makes it easy

The SIMPLUG feed-in technology developed by Wattando is the guarantor for safe feed-in into existing lines downstream of the overload protection: Wattster continuously evaluates the load profile of the domestic grid for this purpose and regulates the feed-in according to relevant parameters.

Wattster will be available in three variants: The first provides for single-phase feed-in from 1 kW to 7 kW, the second variant for three-phase feed-in from 3 kW up to 11 kW. The third planned version, Wattster 3XL, enables a feed-in of 11 kW up to 70 kW.

And off to the customer's network

Single phase from 1 to 7 kW

For the solar system on the garden shed, on the carport or on the roof: the existing household socket is replaced by an energy supply socket. This is a matter of five minutes for a skilled person. Apart from the noninvasive attachment of the bridge to the house network, there is no need for further intervention in the electrical installation. (In Germany, the feed into one phase is limited to a maximum of 4.6kW).

Three-phase from 3 kW to 70 kW

As soon as a three-phase power connection (CEE plug) is available or planned, Wattster enables the pluggable integration of solar systems from 3 kW to 70 kW. For outputs above 11 kW, there will be the WATTSTER XL solution. Interesting for private households but also especially for commercial properties.

Inform about delivery capability

Glad you want to check on the availability of new Wattster systems. Currently, the systems from the first production are sold out. But the production of new systems is already underway!

As a business customer: As soon as systems are available again, we will inform you about the sources where you can purchase Wattster products.

As a private person: We also welcome reservations from private persons. It is true that we sell Wattster exclusively to commercial dealers at first. But we will be happy to inform you as soon as Wattster systems are available for installers.

You can revoke your consent to be contacted at any time. You can find further information in our privacy policy.

Thank you for your interest!
You will get a message when the availability is fixed.
