Achieve Superior Economics in Ground-Mount Projects with 480 VAC Interconnections

Sunny Highpower PEAK3 125 kW

1,500 VDC modular inverter solutions change the game for PV professionals

Opportunities abound for integrators to improve their bottom line with the Sunny Highpower PEAK3 125 kW from SMA—the only 1,500 VDC inverter with the ability to connect to the grid at 480 VAC. For large ground mount projects, SMA’s PEAK3 delivers the most cost-effective solution and highest energy production.

For PV Integrators

Reduced installation costs, faster project completion

In many instances, there is a utility supplied 480 VAC interconnection, which dramatically reduces system cost by eliminating the need to purchase a transformer.
Only SMA PEAK3 with 480 VAC output requires no additional stepdown transformer versus any other 1,500 VDC inverter.
SMA’s centralized, modular system architecture reduces balance of system costs, and speeds installation and commissioning.

For PV System Owners

Increased energy production, reduced O&M and service costs

SMA PEAK3 delivers the highest energy production by eliminating additional step-down transformer losses versus any other 1,500 VDC inverter.
DC line losses are recoverable thanks to class-leading DC:AC ratio of up to 150%.
The absence of a step down transformer reduces service costs and eliminates a potential point of failure.
The PEAK3 enables a centralized modular plant architecture which simplifies O&M.
SMA Smart Connected proactive service technology reduces costly truck rolls and on-site diagnosis of events, while simultaneously increasing uptime and energy production.

What about other 1,500 VDC inverters @ 600 VAC and 800 VAC?

Require an additional step-down transformer to interconnect at 480 VAC
Needs additional engineering, installation and O&M costs
Lower energy yield due to additional transformer losses

What about 1,000 VDC inverters @ 480 VAC?

Require twice as many inverters at higher cost per watt
Higher installation and O&M costs
Lower energy yield due to:
1. Lower conversion efficiency
2. Higher AC line losses
