The Top Three Reasons Why Installers Love the CORE1 Commercial Solution from SMA!

From Matt Marx (guest post) on 01/24/2019 in Category Company with 4 Comments

Since its introduction, SMA’s Sunny Tripower CORE1 has been taking the commercial market by storm. Now with expanded features and functions, installers have even more reasons to appreciate this truly unique commercial PV solution. We compiled the top three reasons that have installers shouting their praise from the rooftop. 

Sunny Tripower CORE1

 #1) Additional power classes and options for repowering

SMA has expanded the Sunny Tripower CORE1 product lineup, building on the successful 50 kW model, and now offers both larger and smaller options. With the 62 kW power class, installers can utilize higher Wp modules while achieving a lower installed cost- per watt in larger rooftop and ground mount installations. This unit produces more power in the same size form factor, so installers retain all the transportation, logistical and installation efficiencies that have become the hallmark of the CORE1 solution.

Many aging commercial systems suffer from underperformance due to a variety of issues. This opens up a new revenue stream for installers to repower these legacy systems and bring them back to full health. However, finding replacement inverters in a market that has gone almost entirely to 1,000 V equipment can be difficult. Have no fear, the CORE1 33 kW is here! This smaller power class operates at 600 V and is the ideal solution for repowering distressed commercial PV plants. Installers love being able to compete for new (old) business with this solution from SMA.

The entire CORE1 lineup still offers the fastest commercial installation with twelve direct string inputs, six independent MPPT channels and integrated AC and DC disconnects. All power classes also include advanced grid management functionality including compliance with California Rule 21.

#2) A cost-effective option to meet NEC 2017 requirements

There are various methods to achieve compliance with NEC 2017 690.12 rapid shutdown requirements. Once such method is to use power optimizers throughout the array. However, costly power optimizers scale poorly in commercial arrays and provide limited benefit beyond shutdown. SMA provides the most cost effective solution to this challenge with the TS4-R-F module-level shutdown device. This solution utilizes the power line based SunSpec communication signal for rapid shutdown, making it simple to implement with robust functionality. No additional communication hardware is needed because the shutdown transmitter is integrated within the CORE1, reducing cost and speeding installation.

#3) Smart service technology that saves time and money

Truck rolls can eat into an installer’s bottom line and should be minimized in order to focus on new business and other revenue generating activities. The CORE1 lineup features an innovative new technology called SMA Smart Connected that can cut service truck rolls in half. This proactive solution provides continuous system monitoring and automatically alerts an installer when an event is identified. What’s more, SMA Smart Connected will send the installer troubleshooting tips in order to expedite servicing. If a replacement inverter is needed, the RMA process is automatically initiated so the installer only needs to make one visit to the site. Alternatively, if there is simply an issue with one of the inverter control boards, that component can be shipped to the installer for replacement. This expedites the repair process and further speeds servicing onsite. SMA Smart Connected is powered by ennexOS, the Intersolar Award winning solution for cross sector energy management.

    I’d love to use this product, but I have an issue with running PV Source Circuit conductors in direct sunlight (even though they’re sunlight resistant). It doesn’t appear that there is any way to avoid this. Also, what if I want to mount the inverter to a wall inside? We cannot run the PVSC conductors exposed.

    Lastly, your installation video shows the PVSC conductors coming out of a conduit adjacent to the inverter without a bushing. Can’t do that. Another photo shows the inverters shading the array.

    Lastly lastly, why can’t you make a 208V version? A large percentage of rooftop installations in the US are on properties with 208V services. We could install a transformer, but that costs more time and money. SolarEdge makes multiple solutions, but we really want to say goodbye to that company.

      Doug – Of course actual installations should follow all required codes. Some customers faced requirements to cover all wiring and have constructed a shroud for the DC connection area and used a cable tray between array and inverter. SMA understands there are situations where a transformer has no space, or is a large percentage of the system cost, but the reduced energy losses transmitting off the roof at 480 VAC rather than 208VAC led to the decision on output voltage.
