Kaco Inverters

Kaco3002 inverter pictureBy installing a KACO 02 series inverter as part of your grid-tie solar system you have the reliability and performance of a German-made inverter but have the ability to upgrade at a later time to a fully functional Solar Hybrid or Grid Support power system. Using the Selectronic / KACO AC coupling system the KACO 02 series inverter integrates seamlessly with the Selectronic SP PLUS energy centre to form a highly sophisticated, fully managed Solar Hybrid energy storage system. System sizes range from 3kW to 20kW single phase (with up to 30kW of PV solar), 6kW to 40kW split phase (with up to 60kW of PV solar) and 9kW to 60kW three phase (with up to 90kW of PV solar).

The KACO Powador 02 series of inverters range from outputs of 1650 W to 5000 W and feature a totally convection cooled thermal profile on all models below 5000 W, meaning there are no fans to break down or draw dirty air into the sealed IP54 rated enclosure.

Other features include:

Suitable for AC Coupling to SP PRO in ON Grid or OFF Grid Continuing to advance the highly acclaimed SP PRO technology, Selectronic in co-operation with KACO Germany are pleased to release a further development to our AC Coupling methodology, now appropriate for Off Grid and Diesel Grid use as well as Solar Hybrid (Grid Backup). By connecting up to 5 KACO Grid Tie inverters to the AC Load side (output) of any single phase SP PRO system, it is now possible to utilise efficient high voltage PV arrays that are located remotely from the battery bank. This allows you to continue to use a wide choice of PV installers and common components; no need to be concerned about cable loss in long, expensive low voltage cable runs. By creating an AC Bus, an AC Coupled system will allow PV energy to be efficiently used directly by the load with excess PV energy going back through the bi-directional SP PRO to charge batteries or export to the grid. PV energy will continue to be utilised at all times, regardless of generator or grid availability. The battery charging system in the SP PRO has proven unmatched in control and stability. This has now been extended into PV based AC Coupled systems.

The SP PRO/KACO RS485 link provides the same precise control over the AC Coupled PV. Regardless of the charging source, your batteries will enjoy maximum life with SP PRO charging. The KACO grid inverter can be considered as an AC MPPT. A maximum of 5 KACO inverters can be controlled by any SP PRO, but the total AC Output of the combined KACO inverters must not exceed twice the continuous power rating of the SP PRO or the SP PRO surge rating, whichever is smallest. Presently, the KACO Powador 02 series supplied by Selectronic are suitable for AC Coupling. The 02 series range from 1.65kW to 5kW AC output. Site consumption and generation data continues to be logged by the SP PRO including the AC Coupled solar production.
