To better support our customers across a wide range of inverter platforms—whether using domestic or non-domestic content—we are introducing new capabilities designed to enhance both performance and flexibility. These updates aim to ensure greater compatibility and more seamless integration across diverse project requirements.

Bottom Line:

  • Non-Domestic Synergy Managers are compatible with both non- and Domestic Synergy Units
  • Optimizer: Non-Domestic Synergy Managers and Three Phase Inverters are NOT compatible with C651U

Partial compatibility due to non-fused inverter. If using more than 2 strings per unit, then either:
1) Use inline fuses
2) Increase wire sizes

Full compatibility with DC Combiner box (external to inverter)

 

Bottom Line:

  • New Managers (DBL, TRI) are compatible with both non- and Domestic Synergy Units
  • Optimizer: New Synergy Managers and Three Phase Inverters are compatible with C651U and partially compatible with legacy Power Optimizers
  • Universal Solution: Single DC Input Synergy Manager (W4) with DC Combiner box is fully compatible with all SolarEdge Power Optimizers

Frequently Asked Questions

Can I mix domestic and non-domestic Synergy units in the same system?

Yes, they are completely interchangeable and have no installation differences. You
can even mix them within a single 4-box.

What if I have legacy Synergy Managers but no Synergy units, only P960s?

You can use either non-domestic or domestic content Synergy units with those
legacy Synergy Managers.

Do I need special equipment when using domestic content Managers with legacy Power Optimizers?

Depends on the Synergy Manager type:

  • Unfused Managers (DBL, TRI): Yes, these require inline fuses (Stäubli recommended) OR increased wire gauge, especially for three-string designs
  • With C651U Power Optimizers: No special requirements
  • Single DC input: Always requires DC combiner box (the same as before)
Will SolarEdge Designer support these compatibility scenarios?

Coming soon. Designer will be 100% updated with compatibility checking and warning messages for configurations requiring special attention.

Is there a recommended fusing kit?

Yes, Stäubli inline fuses are recommended and available through distributors.

What about using single DC input Synergy Managers?

This is the "universal solution". It works with both legacy and domestic content Power Optimizers when paired with a DC combiner box. It always requires the combiner box regardless of optimizer type.

Thank you for your partnership as we transition to wider domestic manufacturing.
