- System configuration page. A SolarEdge SE120KUS inverter is built from 1 × SE-TRI-US00IBNS4 Synergy Manager (configured to 120 kW) plus 3 × USESUK-USR0INNN8 Synergy Units, with C651U power optimizers on the array.
- 120,000 W rated AC power on 480V three-phase grids; 98.5% CEC weighted efficiency (SolarEdge datasheet).
- System pricing is quoted per project (components, quantities and freight). Each component page shows its own price.
- This page previously listed the older SE120K-US08IBNZ4 Synergy Manager, which CSE no longer offers.
What makes a SolarEdge SE120KUS (120 kW) inverter
SolarEdge Three Phase Inverters with Synergy Technology are modular: a Synergy Manager plus three Synergy Units form one 120 kW inverter for 480V three-phase grids. There is no single part number for the complete SE120KUS; it is ordered as components and configured by SolarEdge SetApp at commissioning.
Pricing note: the price of a Synergy Manager is not the price of a complete 120 kW inverter. CSE quotes SE120KUS systems per project, including the manager, three Synergy Units, C651U optimizer quantities and freight.

Domestic content
Per SolarEdge, the USESUK-USR0INNN8 Synergy Units and C651U optimizers are USA Domestic Content Eligible; the SE-TRI-US00IBNS4 Synergy Manager is not manufactured in the USA and is not counted. Project qualification depends on the whole project; confirm with your tax advisor.
Looking for SE120K-US08IBNZ4?
SE120K-US08IBNZ4 is an older-generation SolarEdge Synergy Manager part number that this page used to list. CSE no longer offers it. The current Synergy Manager for SE120KUS is SE-TRI-US00IBNS4. If you are servicing or expanding an existing Synergy installation, send CSE the part numbers on your installed manager and units so compatibility can be confirmed before ordering.
