DC Power Optimizer

Category: infrastructure

A panel-mounted module that optimizes DC voltage before routing it to a centralized string inverter system.

A hybrid option between string and microinverters. Power optimizers execute panel-level MPPT adjustments locally, isolating underperforming shaded panels so they don't choke the rest of the series. The optimized DC power is then combined and sent to a standard, lower-cost central inverter.

Common Examples

• By deploying DC power optimizers beneath every panel, we secured the shade mitigation of microinverters with the durability of a central engine.
• The optimizers automatically step down voltage limits during an emergency, satisfying the strict NEC rapid shutdown security covenants.
