After completing the initial settings, switch off the 3000SP inverter by disconnecting the
connection line to the electrical grid, and bring the battery switches to the OFF position.
Switch the 3000SP back on again by carefully following the steps described below for correct
calibration of the current sensors.
IMPORTANT: CAREFULLY FOLLOW THE PROCEDURE BELOW.
1)
Switch off the photovoltaic inverter. Make sure that no power is being generated on the AC line.
2)
Switch on some domestic loads; make sure (using a current sensor, if necessary) that the electrical
consumption of the utilities is greater than 200 W.
3)
Set the switches of all the batteries installed to ON; if Pylontech batteries are used, the green LED
located under the switch will light up.
4)
For Pylontech batteries, press the red SW button on only one of the batteries installed for one
second; the row of green LEDs underneath the word SOC will light up and then go off. Repeat this
for all the batteries connected in parallel.
5)
Close the DC circuit breaker, if any, positioned between the battery and 3000SP inverter.
6)
Close the AC circuit breaker between the 3000SP inverter and grid. The display will light up and
the 3000SP inverter will start operating.
7)
It should now be possible to read the power imported from the grid on the display; make sure that
the power imported from the grid coincides with the power consumed by the household loads.
8)
At the end of the 300-second countdown (if the country code is set to 01 according to CEI 201) if
the batteries are sufficiently charged, they will start to deliver power and supply energy to the
loads, reducing or cancelling the energy being withdrawn from the grid. Check the display to see
whether the sum of the power flows entering and exiting from the inverter are the same.
9)
Start the photovoltaic inverter. If the current sensors have been correctly positioned, the
photovoltaic output shown on the display of the storage inverter must be the same as that shown
on the display of the production inverter.
