What is a Microgrid


A microgrid is an on-site energy system that integrates several distributed energy technologies into a single controllable solution. It can operate by supplementing the utility company's power grid in "grid parallel mode", or completely autonomously in "island mode". By having this capability, we’re able to deliver our customers cleaner, cheaper, and more resilient energy.

A Microgrid Consists of Several Components

Simplified Microgrid Diagram

A microgrid ensures access to electricity at all times, even when the power company cannot generate enough energy to supply needs. Batteries or other stand-alone equipment (e.g., generator) are required for a fully functional microgrid solar system and adds to the costs as well as maintenance. 

Microgrid Benefits

Inspector Friendly
Cost Effective
Low Maintenance
Versatile Modular Design
Multi Power Source
Easy Installation
Minimal Attendance Required
Sustainability and Environmentally Friendly

​Microgrid Components


Solar PV

Captures the energy of the sun on-site - 100% renewable energy.


Battery Bank

  • This is essentially a group of batteries wired together. Combined with the solar PV, this allows you to maximize the impact of on-site renewables. 
  • Battery Storage units reserves energy for later consumption and is charged by a connected solar system. The stored electricity is consumed after sundown, during energy demand peaks, or during a power outage. 


Solar Charge Controller

  • Solar charge controllers are also known as charge regulators. It limits the rate of current being delivered to the battery bank and protect the batteries from overcharging.
  • They are crucial for keeping the batteries healthy, which ensures the lifetime of a battery bank is maximized.  If you have a battery-based inverter, chances are that the charge controller is integrated.


DC Disconnect

  • AC and DC safety disconnects are required for all solar systems.
  • For microgrid solar systems, one additional DC disconnect is installed between the battery bank and the off-grid inverter. It is used to switch off the current flowing between these components. This is important for maintenance, troubleshooting and protection against electrical fires.


Microgrid Inverter
There`s no need for an inverter if you`re only setting up solar panels for your boat, your RV, or something else that runs on DC current. You will need an inverter to convert DC to AC for all other electrical appliances.

Cogeneration
These highly efficient natural gas engines provide reliable and flexible power generation. These engines are an option to use as backup to the battery storage, especially if you need power 24 hour/7 days per week.


Cogeneration therefore offers energy savings ranging between 15-40% when compared against the supply of electricity and heat from conventional power stations and boilers. Cogeneration optimizes the energy supply to all types of consumers, with the following benefits for both users and society at large:


  • Increased efficiency of energy conversion and use. Cogeneration is the most effective and efficient form of power generation.
  • Lower emissions to the environment - primarily CO2 (the main greenhouse gas). Cogeneration is the single biggest solution to the Kyoto targets.
  • Large cost savings. Cogeneration provides additional competitiveness for industrial and commercial users.


Remote Monitoring

The remote monitoring system provides transparency to our users and engineers. Being able to remotely monitor PV systems is important to reducing time and costs associated with site visits. This is especially important for microgrid systems, which are often in even harder to reach or remote areas.


  • Reduce costs associated with remote site visits.
  • Receive quick notification and act quickly to eliminate power interruptions at a site.
  • Facilitates troubleshooting
  • Ability to customize program settings off-site
  • Update firmware remotely


Service / Maintenance
Ongoing service and maintenance may be included in pricing. It can include monthly inspections and service.

* Additional optional equipment may be required for special industries, e.g., climate control equipment for some farming applications.
