Evolution in Energy Storage

Evolution in Energy Storage

Ampd Energy is pushing the boundaries to bring energy storage into the 21st Century. By using Li-ion as our storage medium, the Ampd Silo has many benefits when compared to existing technologies.

With a high energy density, the Ampd Silo requires less space per kilowatt, resulting in up to an 80% reduction in floorspace. It can also operate at higher temperatures, allowing for savings in cooling and enabling novel applications, not previously possible.
The battery management system takes 280 readings per second, providing unrivalled protection for each core component. This allows for a longer battery lifetime, zero maintenance and lower total cost of ownership.

Get More for Less

Get More for Less

Enjoy better protection and superior benefits, with lower costs. Comparisons have shown that over the 10-year lifespan of an UPS system, the Ampd Silo will cost you up to 40% less than VRLA UPSs.

These huge savings are achieved through the two major benefits Li-ion has over VRLA. Li-ion has much longer lifespan. Over a ten-year period, you would expect to replace your VRLA batteries 3-4 times depending on usage. Over this same period, you might need to replace your Li-ion batteries once.

In addition, VRLA requires constant maintenance. With the Ampd Silo, all maintenance is performed by software updates, negating the need for maintenance, which can have huge cost savings if you have many batteries or if they’re in remote locations.

Safe and Reliable

Safe and Reliable

Ampd Silo uses the most advanced automotive grade Li-ion batteries to assure the UPS can deliver maximum power when needed. Safety is our priority – seven autonomous fail-safe features assure Ampd Silo is never compromised. This is in line with aerospace safety principles, and no less than your business deserves.

Ampd Silo is the only UPS provider in Asia to secure UL9540 certification, backed up by adherence to CE, IEC and UN standards.
By using multiple Silos, instead of one large battery, you are afforded the protection of (N+1), removing a single failure point. This is known as Redundant Power Protection. You might prefer to think of it as the ultimate peace of mind.

A Truly Eco-friendly Product

A Truly Eco-friendly Product

The Ampd Silo replaces two existing polluting products. Diesel generators are notorious polluters, especially in terms of their PM 2.5 emissions and cancer-causing substances, such as benzene, arsenic and formaldehyde. They cannot be used in-door, are extremely loud and require very frequent maintenance. With the Ampd Silo’s 17kWh battery, finally there is a long-lasting alternative.

Lead acid batteries contain numerous toxic materials many of which do not get properly disposed of at the end of their short lifespan. Li-ion is non-toxic and can be recycled up to 99% and in addition they can be re-used for non-mission critical applications at the end of their standard operating life. Enquire with your local distributor about recycling options in your country.

Li-ion is fast becoming the primary storage mechanism for renewable energies, like solar. The Ampd Silo can be adapted for renewable energy storage, for further information enquire with your distributor.
