Off Grid - Green Cubes Technology | Lithium-ion Power Systems Manufacturer

Off Grid

Microgrids provide power to locations that can’t connect to the grid due to distance or other limitations, operating off grid. Combining the energy generation of solar, wind, and fossil fuel generators with modular energy storage solutions and advanced controls create a hybrid off grid power solution. Off grid solutions power applications such as remote monitoring, telecommunication towers, border security, field research and others.

Solar and wind power generation fluctuates every moment and often don’t match the load demand. An energy storage device is required to smooth out the generation and demand functions of a microgrid. Lithium Ion batteries are an excellent choice for modular energy storage on a microgrid for many reasons.

Lithium Ion batteries can charge and discharge partially to smooth the difference in demand and generation. This allows excess energy during sunny or windy times of day to be stored for use later. Also, partial cycles don’t have any negative effect on the life of a lithium ion battery, as there is no memory effect. Lithium Ion batteries can be charged and discharged thousands of times, which is perfect for wind and solar generation!

Lithium Ion batteries are the critical pillar in a fossil fuel-free economy and their use in electric vehicles and stationary energy storage have grown exponentially in recent years, due to technological advances and significant price declines. This is making Lithium Ion batteries a cost-effective solution for modular energy storage and backup applications over the incumbent lead acid solutions.

Lithium Ion batteries are 98% efficient storing energy. This high efficiency reduces the total power generation demand on a hybrid or microgrid application. If you must run a diesel generator to provide power, you can capture more energy from that diesel and turn off the generator sooner. Diesel generators run most efficiently when loaded to near 100% rated capacity. Once the batteries fully charge the generator can be turned off allowing the load to run on silent, efficient Lithium Ion battery stored energy. This reduces the refueling requirements and lowers the cost of fuel.

Green Cubes manufactures and supplies all the components you need to build an off-grid power system that fits your needs. Green Cubes Battery Backup Units (BBUs) can also be used as modular building blocks of a BESS. Green Cubes Lithium-Ion Systems provide the following benefits over diesel generators:

  • Carbon Footprint
    Lithium Ion battery microgrids with solar and wind offer a clean environment friendly option over diesel generators and their harmful CO2 emissions.
  • High efficiency
    Lithium Ion batteries in an energy storage rack paired with diesel generators improve the efficiency of the system by 30-50%.
  • Less maintenance
    Lithium Ion batteries do not require maintenance like diesel generators or lead acid batteries.
  • Higher energy density
    Lithium Ion batteries packed in an energy storage rack offer the highest energy density storing more energy in less space.
  • Lower Operating Costs
    Lithium Ion microgrid systems require less fuel and maintenance, lowering operating costs significantly.

Customer Ratings and Reviews

Green Cubes is a great company, great engineers, great product. That’s been kind of my number one go to [lithium] battery.

President, Industrial Power Company

The thing I like about Green Cubes is that they have other lines of business outside of material handling batteries, they have been in the lithium world for a long time. I can trust they will likely stay in business

VP, Industrial Battery Company

Green Cubes [differentiates] on its capability to custom design for things like the hardware, the firmware, and inverters. They also have economies of scale because they make battery systems for things like forklifts.

VP, Powered Cart OEM

I am doing some work with them right now. We’re learning their products, and looking at demos. They have good people. They seem like they know the technology well – they say they’re a technology company. I like that they’ve been in the lithium business a long time. I can trust they will likely stay in business.

Sales Manager, Industrial Battery Company

Green Cubes Technology would be my go-to for lithium applications.

Branch Manager, OEM

I’ve told my friends at Green Cubes, I don’t plan on going anywhere. I believe in loyalty.
