Efficient. Flexible. Future-oriented.
Transformerless three-phase inverters Powador 30.0 TL3 to 39.0 TL3.
Since they are true three-phase units, the
Powador 30.0 TL3 to 39.0 TL3 provide
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-
telspannungsrichtlinie" and "Niederspan-
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-
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
operate at 95 % efficiency.
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. The Powador
36.0 TL3 replaces the Powador 37.5 TL3
and the Powador 33.0 TL3, available from
Q2 2012, complements the series.
