PAC Field Outdoor
High power string inverter rack
OELMAIER PAC Field 3 and 6 for high reliability
with above-average yield
Quick installation
The compact string inverter racks of the PACField series are featured by their extreme compact and robust
design, their very fast “on site” installation and their reliability in outdoor surroundings. By using our
approved PAC and PAC-S string inverter family we can guarantee an above-average yield performance as
well as a very good system availability.
OELMAIER Power packs
The integrated, very efficient cooling system provides a constant high power output with no derating due
to overheating, and also dramatically increases the device lifetime. All electrical connections of the string
inverters are performed in the approved plug in technology and ensure that „in case of emergencies“
a very quick and easy exchange of individual devices without additional assembly tools such as cranes,
forklifts, etc.
The PACField racks are completely electrically and mechanically pre-fitted and can be supplied with an
optional integrated data monitoring system.
Thin film suitable
OELMAIER Technology offers the PAC Field system optional with a high efficient and integrated central
transformer. This allows the integrated and transformerless PAC devices a conjunction with all available
thin film modules on the market. As a standard design, we actual offer the model PACField 3 with 21 kW
rated output and PAC Field 6 with up to 42 kW rated output.
Other string inverter combinations in the PAC Field systems are feasible by adequate selection and application of our PAC string inverters. The rack offers a compact space from 1 up to 6 PAC (S) string inverters
and is electrically completely prepared.
