Solar String Inverters
BREK Electronics has redesigned grid-tied Solar String Inverters using novel composite architecture optimized for Silicon Carbide (SiC) components. This enables industry leading 4 x power density in a lighter and more compact system.
Silicon Carbide is 300X better at thermal conductivity vs traditional silicon, which lowers the operating temperatures, leading to fewer failures. Lab tests showed a 10X improvement in the mean time to failure vs conventional silicon.
Silicon Carbide can withstand higher temperatures and handle more energy than silicon. These benefits are paving the way for Silicon Carbide to ultimately slash the cost of solar string inverters.
Why Use a BREK Inverter?
4x Power Density
At 4 kW/kg, BREK’s inverters deliver more power in a lighter, more compact system than other string inverters.
Longer inverter life
Lab tests showed an improvement in the mean time to failure vs conventional silicon, projected to last 2X longer than current models
40% lower maintenance costs
40% lower capital and operations
costs projected over the life
of the inverter
Power curtailment functions
Power curtailment functions built are into our inverter control firmware for active grid monitoring.
BREK uses lightweight planar magnetics and ceramic capacitors, enabling automated manufacturing leading to lower cost per watt.

The Advantages of BREK's Solar String Inverters
"[Brek’s] technology aligns with improvements the commercial solar industry would value. String inverters represent a significant, and ever growing percentage of the equipment deployed on projects across the country. The proposed reduction in inverter form factor and weight along with increased power and heat dissipation would add value to any inverter, and distinguish a given manufacturer over what is currently available in the market."
