Adding, Removing, or Replacing Power Optimizers

1.

Turn OFF the inverter ON/OFF switch, and wait until the LCD indicates that the DC

voltage is safe (<50V), or wait five minutes before continuing to the next step.

WARNING!

If you cannot see the inverter panel, or if a malfunction is indicated on the

LCD panel, wait five minutes for the input capacitors of the inverter to

discharge.

AVERTISSEMENT!

Si vous ne pouvez pas voir l'écran de l'onduleur ou si un dysfonctionnement

est indiqué sur l'écran LCD, attendez cinq minutes pour que les

condensateurs d'entrée de l'onduleur soient déchargés.

2. Turn OFF the Safety Switch .

3. Disconnect and connect the necessary power optimizers.

4. Perform pairing and other procedures described in

Commissioning the Installation

on page 52 on all inverters to which power optimizers were added or from which

power optimizers were removed.

5. In the monitoring platform, use the Replace button in the logical

layout tab (in site Admin). Replace the serial number of the removed

power optimizer with the serial number of the newly installed power

optimizer. Refer to https://www.solaredge.com/sites/default/files/se-
