What is a Microgrid?

A Microgrid is a group of localized electricity sources controlled by a centralized system that operates to power a home or business. Microgrid systems operate autonomously either in tandem with the centralized grid and can form an autonomous Microgrid in the event of a grid power outage. When the power goes out, the Microgrid will continue to operate in a stand-alone or “islanded” mode until the power comes back online. In locations where no utility grid is present, a Microgrid will act full-time as an autonomous or self-contained grid.

What is the difference between a Switch Microgrid and Battery Backup System?

There are many important differences between a Switch Microgrid and a more common Battery Backup System. First, the Switch system can form a Microgrid in stand-alone or “islanded” mode. The Switch system will provide power to the building’s electricity loads and will efficiently manage the Microgrid’s inputs including solar and generator energy input. Additionally, the Switch Microgrid can be used as a fully functioning off-grid system.

The Switch system autonomously controls the Microgrid while monitoring the entire system including the battery, solar and generator status. For more information on monitoring click here.

Can the Switch Microgrid be used as an off-grid system for the entire home or building?

Yes, the Switch Microgrid can be used as a purely off grid system to power all of the building’s electrical loads. The system will optimize any solar and generator input to charge the battery during the day and discharge the battery to run the nighttime electrical loads.

Can a solar system be integrated into a Switch Microgrid?

Yes, solar can be an important input to the Switch Microgrid. Solar can charge the battery during daylight hours as an alternative to pulling power from the grid or from a fossil fuel generator. If solar is used to charge the battery, the Solar Incentive Tax Credit (ITC) can be used to offset 30% of the total cost of a combined solar system and Microgrid.

Can the Switch Microgrid make my generator more efficient – lowering fuel usage?

Yes, the Switch Microgrid controller commands the generator to run only when the battery needs to be charged. So rather than running day and night to meet all electrical needs large and small, the generator will run for only the time it takes to charge the battery.

If and when there’s a power outage, how many hours of autonomy will the Switch Microgrid provide to the building?

Unlike many Backup Battery Systems, the Switch system can be sized to meet all the electrical loads for as little as a couple of hours or indefinitely when coupled with a solar system or a generator. There are many variables to consider when choosing the battery size including the desired number of hours of grid autonomy, solar input, generator input, the type and amount of a building’s loads, and budget.

How are Microgrids typically installed? What are the installation advantages with a Switch Microgrid?

Historically, Microgrid systems have been assembled and installed indoors in the field. The Switch Microgrid was developed to standardize the installation in order to save contractors time and project costs. Assembling a Microgrid in the field invites complications that don’t exist for the factory assembled Switch Microgrid. Assembling and engineering a Microgrid in a factory controlled environment is superior to assembling and engineering complex Microgrids from scratch in the field. Permitting and maintenance is also more streamlined with a Switch Microgrid.

What components are typically included in a Switch Microgrid?

The main components included in the Switch Microgrid are a battery, a bi-directional storage inverter, the Microgrid control system, a climate control system, and a fire suppression system. There are many additional electrical components included in the Switch system enclosure necessary for a fully functioning Microgrid and may change slightly depending on the site needs.

Do the components come pre-wired?

Yes, one of the greatest cost and time savers with the Switch Microgrid is that the components ship pre-wired. Installing a Switch Microgrid can save weeks of field work.

Who performs the Microgrid engineering?

Switch performs the pre-engineering to the UL 9540 standard. However, just like a solar only system, there will be additional engineering necessary for the permitting process. Switch can provide as a service, engineering support and PE stamped drawings as needed. Switch is undergoing the testing necessary to achieve the full UL 9540 standard.

Does the Switch Microgrid come with an installation manual and/or user guide?

Yes, the Switch system ships with an installation manual for the contractor as well as an owner’s manual for the end-user. This is unique to the Switch Microgrid. Because other systems are one-offs, not standardized, and built onsite, an installation guide is not available.

Can a Switch Microgrid be installed both indoors and outdoors?

Yes, the Switch system ships in a NEMA 1 or 4 container and can either be installed outside (usually onto a concrete pad) or it can be placed indoors. Outdoor units ship with climate control to ensure the battery stays within the specified operating temperature range. The unit also ships with an automatic fire suppression system.

How long does it take to install a Switch Microgrid?

Because the Switch Microgrid is pre-assembled, it can be installed in a day or two depending on the site and the integration with the building’s other systems.

What is the footprint of the Switch Microgrid?

The footprint varies depending on which components are used as well as the size of the battery bank. However, a standard size is roughly 4’ deep and 7’ wide.

What is needed to maintain the Switch Microgrid?

Switch Microgrid maintenance is minor and can vary slightly depending on which components are incorporated into the system. There is no maintenance needed for the battery, the enclosure, or the controller. Depending on which inverter is used, there may be maintenance for the inverter. The HVAC and fire suppression systems may require periodic checks.

What is the difference between a Switch system and another brand name residential Li-Ion storage systems?

Switch uses commercial grade batteries racks for all its storage products. Our smallest battery rack is 34 kWh and our standard rack is 69kWh. Our racks can be paralleled for additional storage needs depending on the client’s application. Traditional residential Li-Ion battery are much smaller 8-12 kWh and have limitations on how many batteries can be run in parallel.

Does Switch offer single and 3-phase systems?

Yes, Switch offers single phase systems 120/240 from 18 kW to 200 kW. Our 3-phase system starts at 30 kW and goes up to 500 kWh.

How can I monitor my Switch microgrid system?

You can monitor your Switch system from any smart device or PC which is connected to the internet. Switch will soon offer a phone application to monitor your system. Switch also provides a local direct interface to the site controller thru an HMI touch screen to allow local monitoring and troubleshooting if needed.

What if I need to quickly shut down my storage system?

Each Switch system is provided with an E-Stop push button (Emergency Stop). When actuated the E-Stop opens the battery contactors located in the battery BPU to stop the flow of battery energy to the inverter.

How will I know if my system is performing correctly?

Your Switch system is being monitored by ELM FieldSight controller 24/7 thru an internet connection. If ELM sees a system fault or warning, you will receive a text and email on the notification. Many times ELM will remotely correct the fault eliminating the need for a field service call.

What if my utility changes my current rate structure or time of use charges?

Let’s say your utility changes your time of use charges from midday to early evening. If you have a building PV system you would now want to store the PV energy during the day and deploy it during high rate times during the evening. Switch can work with you to remotely change the charge-discharge parameters of your system to provide you with the best financial payback of your system.
