USE OF FRONIUS INVERTERS WITH THE
APID PID RECOVERY SYSTEM (ANTI-PID-SYSTEM)

Fronius International GmbH

hereby confirms that the below listed inverters (table 1) may be used together with the above mentioned device
without voiding our commitments as stipulated in our Fronius warranty terms and conditions, provided that:

/ the described settings are fulfilled (see table 1) and
/ by following all relevant instructions (Installation Instructions, Operating Instructions, Safety Instructions, ….).

This authorization relies on tests, carried out and documented by Elettrograf s.r.l. (manufacturer of APID).

When using the accelerated regeneration (APID manual, top of page 10 - To speed up the regeneration ….) the
DC disconnector (from the inverter) has to stay switched off the whole time!

Fronius declines any responsibility for any direct or indirect damage, injury or losses, arising or resulting from
any malfunction, misuse, wrong setting or defect, apart of the scope of our warranty terms and conditions.

Fronius reserves the right, to resign this approval at any time, with immediate effect and without any
information, for example if the technology or device shows disadvantageous effects for inverters or other parts
of the system, or if new features interfere in any way.
