The SolarEdge USE-SIN-USR0IBNS8 becomes an SE10KUS or SE17.3KUS on 208 V grids, or an SE30KUS or SE40KUS on 480 V grids. The installer selects the class in SolarEdge SetApp at commissioning; SolarEdge notes the selection is permanent.

50–120 kW Synergy inverters, built from components
A SolarEdge Synergy inverter is one SE-TRI-US00IBNS4 Synergy Manager plus three USESUK-USR0INNN8 Synergy Units, with C651U optimizers on the array. SolarEdge configures the manager as SE50KUS (208 V) or SE100KUS, SE110KUS or SE120KUS (480 V). Complete systems are quoted per project; component prices are shown individually and are not system prices.

*Per SolarEdge, USESUK-USR0INNN8 Synergy Units are compatible only with the SE-DBL-US00IBNS4/W4 and SE-TRI-US00IBNS4/W4 Synergy Managers, and are domestic content eligible when installed with C651U optimizers. The Synergy Manager is not manufactured in the USA. Servicing an older Synergy installation? Send CSE the part numbers on your installed equipment before ordering.
C651U for SolarEdge commercial inverters
The USA-manufactured C651U pairs with SolarEdge three-phase commercial inverters (SIN) and Synergy systems (DBL and TRI) for module-level optimization and built-in PV rapid shutdown.
SolarEdge C651U Commercial Power Optimizer
Design rules from SolarEdge
- For commercial three-phase inverters with part numbers xSE-SIN-US…, SE-DBL-US… and SE-TRI-US… only.
- C651U cannot be mixed with any other power optimizer model in the same string.
- 208 V inverters: 13–57 optimizers per string. 480 V inverters: 18–57 optimizers per string.
- Not for SolarEdge TerraMax inverters.
- Previous-generation SolarEdge P-series commercial optimizers remain listed in the full catalog below for reference and service.
Which SolarEdge commercial components are domestic content eligible
As published by SolarEdge. Eligibility of a project for any domestic content bonus depends on the whole project; confirm with your tax advisor.
| Component | Per SolarEdge |
|---|---|
| USE-SIN-USR0IBNS8 three-phase inverter | Domestic content eligible when installed with C651U |
| USESUK-USR0INNN8 Synergy Unit | Domestic content eligible when installed with C651U |
| C651U commercial power optimizer | Domestic content eligible; manufactured in Tampa, Florida |

Frequently asked questions
What is the difference between the three-phase inverter and a Synergy inverter?
The USE-SIN-USR0IBNS8 is a single-enclosure three-phase inverter that is set to 10, 17.3, 30 or 40 kW at commissioning. Synergy inverters are modular: one SE-TRI-US00IBNS4 Synergy Manager plus three USESUK-USR0INNN8 Synergy Units form a 50 kW (208 V) or 100, 110 or 120 kW (480 V) inverter.
Does the SE-TRI-US00IBNS4 price include the Synergy Units?
No. The SE-TRI-US00IBNS4 listing is the Synergy Manager only. Each inverter also needs three USESUK-USR0INNN8 Synergy Units, which are priced per unit. CSE quotes complete Synergy systems per project.
Can C651U optimizers be mixed with other SolarEdge optimizers?
No. SolarEdge states that the C651U cannot be mixed with any other power optimizer model in the same string, and that it is for SIN, DBL and TRI commercial three-phase inverters.
Why do these products show Call for Availability instead of Add to Cart?
Commercial SolarEdge equipment is confirmed per project. CSE checks current availability, lead time and freight to your site before an order is placed, so the listed price is shown with a Check Availability button.
What happened to the SE100K-US08IBNZ4 and SE120K-US08IBNZ4 listings?
Those older Synergy Manager part numbers are no longer offered by CSE. The same pages now describe the current SE100KUS and SE120KUS Synergy systems and link to the current components.
