Start the 3000 SP storage inverter
Supply DC power to the inverter by correctly switching on the batteries:
In the case of Pylontech batteries, set the POWER switch of the battery, or (in the case of
multiple units) of all the batteries, to I (ON position), then press the red SW button of the master
battery for about one second; at this point the LEDs of all the batteries will light up in sequence,
and after a few seconds will turn off, except for the RUN indicating LED.
Figure 50 – Battery status after setting the POWER switch to ON and pressing the SW button
In the case of WeCo batteries, press the RUN button for about one second; after releasing it, wait
for the sound inside the battery indicating the closure of the relay. Repeat the operation for all
the subsequent batteries in the system.

c)
Supply AC power through the dedicated protection switch of the storage inverter. If there is
more than one switch protecting the inverter (e.g. a circuit breaker and differential switch), they
must all be set to ON to allow the inverter to be connected to the grid.
