Product Description:

SMA - Highpower Peak3-US, SHP125-US-20

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. PEAK 3 stands for pure power. With its compact design, the inverter offers maximum power density at minimum weight. This results in less expensive transportation and simplified installation. In combination with the project-specific DC Combiner Boxes, the PV array can be oversized up to 150 %.

  • »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.

SMA Smart Connected

Investment security included

With SMA Smart Connected, SMA offers free and automatic inverter monitoring that helps installers to provide customers with a quick, targeted service. If an inverter fails, SMA proactively informs the PV system owner and the installer. In this way, PV system owners and installers benefit from minimized diagnosis and downtime. If it is necessary to replace the inverter, SMA sends a replacement device fast and free of charge.
  • Frequently Asked Questions

How does the SMA inverter work?

The SMA inverter is the core of SMA Energy Systems for your home. It converts the direct current generated by the roof-mounted PV system into alternating current as required in your home and the utility grid.

How do I know if my SMA inverter is working?

If there are no error codes, take a look at the LEDs. They should all be lit up green if the inverter is working properly. A green light on the outside of an older SMA inverter indicates that there is more than 90% output (which is excellent). A light flashes if it's below 90%

How do I add an inverter in the Sunny Portal?

1. Log into Sunny Portal. 
2. Select system. 
3. Select the menu Configuration. 
4. Select [Device management] in the context menu. 
5. Select the button. 
6. The system setup assistant opens. 
7. Select SMA device and confirm with [Next]. 8. Enter the PIC and RID of the new device and confirm with [Identify]. 
9. Select new device from the list and confirm with [Save].

Can I leave my inverter on all the time?

Once the batteries are fully charged they consume power less than 1% of their capacity. Hence keeping the inverter ON won't make any difference in your electricity bills. On the other hand, if you are leaving your home for 1 to 2 months you can switch off your inverter.

How much can you oversize an SMA inverter?

SMA takes the effect of short-term solar irradiation increase (mirror cloud effect) into account with a high short circuit capability on the DC side of the inverter. This corresponds also to an outstanding oversizing possibility of up to 250 % (peak PV array power in relation to the maximum AC inverter output power).

What is the minimum voltage required for SMA inverter?

The SMA Sunny Boy inverters' minimum DC voltage is 100V , however it requires 125V to start up.

What is the efficiency of the SMA inverter?

SMA Sunny Boy Inverters have average maximum efficiencies of 97%. Renowned for their high quality, installing a SMA inverter is a very safe bet.

Is the SMA inverter hybrid?

The three-phase hybrid inverter for homeownersWith this, SMA has combined smart technology and integrated services to create a space-saving compact system, drawing on more than 30 years of experience in storage. With Sunny Tripower Smart Energy, users can easily and conveniently generate, use and store solar power.

Is SMA battery ready?

Battery ready anytime with SMA's intelligent AC-coupled technology, your Sunny Boy PV system is battery ready at anytime.

Is SMA a string inverter?

SMA is almost unique in the PV industry as manufacturers of the full range of inverter technologies (micro, string & central). SMA's main goal in this regard is to ensure systems are designed using the most appropriate inverter technology.

What is the design life of SMA inverter?

The 25-year design life projection has been confirmed by rigorous design validation and reliability testing, including climate chamber testing, extensive field testing, and accelerated lifetime tests.

Are SMA inverters made in USA?

Our inverters call Colorado home. At SMA America, we're continually investing in American craftsmanship. With our Denver-based production facility, SMA operates the Western Hemisphere's largest PV inverter assembly line.

Do SMA inverters have rapid shutdown?

SMA residential solutions feature our proprietary ShadeFix technology paired with a SunSpec certified shutdown device, which third party testing has shown produces more power. It's also the fastest, simplest installation of any residential PV solution on the market.
How do you read a SMA inverter display?
To read the LCD display of your SMA Sunny Boy inverter, tap the face of your inverter near the display. The LCD screen will illuminate and begin displaying information. Most models display only two lines of text at a time and scroll through several informational messages.
