With the "Wattster" energy management system, you as an installer can connect:in classic PV systems from 1kW to 70kW without interfering with the existing electrical system. This saves time and effort - for your customers too. In short: Plug & Play for PV professionals.
Are your customers unable or unwilling to lay an AC cable and signal cable from the inverter to the house connection? With the Wattster system, you save your customers having to make changes to their home electrics and integrate systems and home storage units into the existing AC grid in less than 30 minutes. Once the components (PV modules, inverter, Wattster, energy meter) have been physically installed and wired, it takes less than five minutes - and the system is ready for operation.
Wattster is an active energy management system that enables existing lines to be used for the feed-in. The Wattster connected to the inverter continuously protects the feed-in line used against overload and - if desired as a self-consumption system - also ensures that zero feed-in is maintained. This enables locally generated electricity to be fed into the grid safely and in compliance with standards, far beyond the previous limits of plug-in solar solutions.
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 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.
Wattster meets the electrotechnical specifications for potential overload in the house network.
Zero feed, netmetering and peak shaving - Wattster enables different feed-in profiles.
Fulfils country-specific specifications for a feeder behind the fuse.
"Wattster Home" for your customers offers a quick look at generation and consumption with the energy monitor
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).
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.
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.
Because it's easier and faster, installation companies can plan differently:
- less time for the electrician on site,
- put more customer systems into operation per day,
- or meet demand from new customer groups; for example, tenants, homeowners or tradespeople (for whom the effort for classic installation is too high or not possible).
Or: Setting up your own "plug-and-play" installation team? Clear! This is one of the many options that result from the simplified integration with Wattster.
Send us your e-mail address, an indication of your area of interest and we will inform you as soon as the Wattster is available or there are further news from Wattando.
