eSite Telecom Site Power Systems

INTELLIGENT POWER HARVESTING FOR LOWEST TOTAL COST
OF OWNERSHIP

eSite x10 delivers the industry’s most comprehensive and intelligent power harvesting from multiple energy sources, whether good grid, bad grid, solar or generator.  This is one of the reasons why eSite x10 excels compared to its competition.  It’s a rectification system with a very wide operational range and built to withstand a wide range of power surges.

eSite x10 is ruggedized in its overall design with components which themselves have been ruggedized.  The system is also equipped with three independent rectifier channels per unit.  External additional rectifiers are not required in order to achieve the necessary power conversion redundancy while at the same time the peak power conversion efficiency occurs at 95% power utilization or higher, significantly better than in competing systems.

eSite x10 has been designed for the lowest possible total cost of ownership (TCO), with a mean time between failures (MTBF) of over 350,000 hours in even the most challenging outdoor telecom site environments.

It avoids unexpected OPEX exposure for callouts to the site due to tampering, clogged cooling filters, fake spares, damaged electronics (due to bad quality power inputs), etc., because it has been designed from the ground up to be immune from all of these typical issues.  In fact, the eSite x10 unit – with its ruggedized, tamper-proof sealed unit and no moving parts – requires almost no maintenance.  In the unlikely event of failure, the entire top compartment is simply hot-swapped with zero downtime.

As for the rest of the site infrastructure, eSite x10’s fully integrated eSite Tools suite collects all the necessary data to optimise service visits for gensets, batteries and any other attached peripheral equipment.  Site visits can therefore be properly planned, enabling the right person with the right tools and spares to be sent to the site, thus enabling a huge reduction in typical operational spending.

eSite x10 has a typical payback period for diesel-site upgrades of less than one year

Opex Savings

eSite x10 delivers Opex savings at all site types.  Its robust design ensures that call-out costs will be kept to a minimum.  By using eSite x10 throughout the network, its integrated eSite Tools RMS secures complete visibility of and insight into the operation, enabling accurate decision making time after time.  And eSite x10’s control of gensets and battery banks ensures their longevity, by running the gensets in their optimal range and managing optimal charging and discharging cycles of the batteries.

Good Grid
When deployed at a good grid site, eSite x10 allows the combination of rectification of the grid power with solar energy, for which solar converters already are an integrated part of the unit.  In locations where grid power is expensive, adding solar power to those sites, in combination with a battery bank, has never been as easy as with eSite x10.

Bad Grid
When deployed at a bad grid site, eSite x10’s integrated protection against power surges and grid instability come in to its own.  And its unique soft switching allows easy integration with other power sources.

Off Grid
When deployed on an off grid site, eSite x10’s resilience and robustness is especially important, as they are typically remote and visiting them for whatever reason is therefore very costly.  The need for such visits can be greatly reduced through the use of eSite x10.

eSite x10 Solar Opportunity

Solar Opportunity

The eSite x10 RSY has built-in support for 6kWp solar power (or ~40sqm of solar panels), as this is typically what can be effectively fitted into telecom tower sites.  With the harvesting of solar energy reducing the use of diesel power and increasing battery life, the result is a very short payback period for solar panels.  And as solar panel prices continue to commoditise, the business case for solar power will only continue to improve.

Grid Harvesting

In some cases operators will avoid connecting sites to a highly unstable power grid due to the damage it can cause to a telecom site power system’s power electronics.  But in doing so, the opportunity to harvest valuable grid power is lost. 

Not so with eSite x10 with its built-in electrical protection systems.  eSite x10 brings harvesting of available grid power to the next level, with its wide tolerance for voltage and frequency variations and where power can be harvested from any single grid phase at a time.  In addition, reliable eSite Tools data facilitates system optimisation through understanding the power grid’s characteristics at each site over time.  So regardless of whether the available grid is good or bad, eSite x10 maximises power harvesting.

eSite x10 battery management

Battery Management

Batteries make up a significant part of any telecom site power system investment, so eSite x10’s control software has been optimised in conjunction with a range of major battery suppliers to maximise battery life and site performance – both critical for achieving a low TCO.

Sustained Performance

eSite Tools – eSite x10’s built-in remote monitoring system (RMS) system – ensures reliable and complete data from the network, including batteries, genset power, solar power, etc. To maintain sustained performance over time, it is important to track site performance versus target KPIs for different site types and to create deviation reports for proactive follow-up. Batteries make up a significant part of hybrid site CAPEX, making network-level tools for replacements and potential warranty claims key to reach sustainable performance targets.

Ancillary Equipment Agnostic

eSite x10 is designed to work with all makes, models and technologies of ancillary equipment, whether generators, batteries, solar panels, etc.  It can also be integrated with any third-party remote monitoring system and it suits all site types, including good grid, bad grid and off grid.
