7.3 AC OUTPUT
The WPC has an continuous AC output “Gen/Grid/Inv”. It also has an switched AC output which is
named Gen/Grid both located at the output board. This Gen/Grid output is switched on only when
there is a valid AC input available. Figure 4 shows the AC output state when no AC input is
available.
Figure 4 – AC out with no AC input available
Figure 5 shows the situation when there is AC input available, note that both the GGI and GG
output are now active.
Figure 5 - AC out with AC input available
Connect devices which should not be powered by the batteries to the Gen/Grid output, such as
boilers, battery chargers etc.. In case of an AC input loss, these devices will not drain the batteries
because they are switched off automatically.
The state of the Gen/Grid output can be overruled by parameter [1311] “Operating mode AUX 2”,
it can be set to Off, On, Automatic and Reversed Automatic. The default setting is automatic.

Operating mode (Aux 2)
Automatic
If this parameter is set to On, then the Gen/Grid output will always be on, just like the
Gen/Grid/Inverter output. If it is set to ‘Off’, there will never be AC output on the Gen/Grid AC
output. If set to ‘Reversed Automatic’ then the Gen/Grid AC output will be on when there is no AC
input(!) and Off when there is AC input.
