Selectronic Managed AC Coupling

To utilise all of the possibilities of an SP PRO, it needs to work with a Selectronic Certified grid-tie inverter.

These inverters contain hardware and software to enable direct communication with the SP PRO. This means that the SP PRO has control of the flow of energy from the solar panels with as fine control as 0.1% steps. This is known as Managed AC Coupling technology which was developed by Selectronic in 2010, and cannot be achieved with a generic grid-tie inverter.

The Selectronic Certified grid-tie inverter can be considered as an AC MPPT. 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 multi-mode SP PRO to charge batteries or export to the grid.

A maximum of five (5) Selectronic Certified inverters can be controlled by any single SP PRO, but the total AC output of the combined grid-tie inverters must not exceed twice the continuous power rating of the SP PRO, or the SP PRO 30 second rating, whichever is smallest.

When using a Selectronic Certified grid-tie inverter, site consumption and generation data will be logged by the SP PRO including the AC coupled solar production.
