Data sheet Efficient. Flexible. Future-oriented. Transformerless three-phase inverters Powador 30.0 TL3 to 39.0 TL3. Since they are true three-phase units, the high-quality, sinusoidal alternating cur- rent with a 120-degree phase shift - a dream come true for all grid operators. It goes without saying that they meet all of the requirements of Germany's Medium Voltage and Low Voltage Directives ("Mit- These transformerless inverters give you extreme flexibility in designing your PV system. They operate with three separate MPP trackers that can handle symmetric as well as asymmetric loads to allow for optimum adjustment. Each tracker is able to process 20 kW. This allows for all ty- pical requirements of complex designs to be fulfilled; on the one hand, for example, full configuration of an east/west-facing roof (symmetrical load) or, on the other hand, the regular configuration of a sou- th-facing roof without having to dispense with the solar yield of a dormer (asymme- trical load). 1 or 4 strings can be connected for each MPP controller depending on the version, therefore 3 or 12 strings for each device. The nominal input voltage range is extre- mely wide: 350 to 800 V. The inverters connect to the grid from 250 V upwards. Once in operation they can feed in with as little as 200 V thus ensuring that even so- lar yields of comparatively small areas like dormers or carports are reaped. The peak efficiency is an impressive 98%. Thanks to the innovative solution for the design and control of the inverter bridge, the devices also realise a very high parti- al load peak efficiency in the lower power ranges: Even at just 5 % rated power they It is easy to achieve perfect communi- cation with these units. In addition to the normal RS485 interface, which ena- bles you to query yield data using the Powador-proLOG, they offer highly con- venient innovations: an integrated web server for uninterrupted monitoring via Ethernet, a USB connection for installing software updates and a graphic display to view operating data. The latest software updates are available for free in the down- load area at www.kaco-newenergy.de/ A number of country-specific default set- tings are programmed into the inverters. These are easy to select during on-site in- stallation. Your choice of operating langu- age is independent of these settings. You save money because the separate connec- tion box makes installation extremely easy. Our three-phase units can of course be combined with each other and are there- fore also suitable for significantly higher power ratings. You can operate the units with an integrated generator junction box (GJB) that accommodates string fuses and overvoltage protection as well as the ex- ternal combiner box Powador Mini-Argus. The market received the series very well. This prompted us to enhance and rear- range it so that it is now available in even finer power increments.
