In 2011 SIRA introduced its EMS Energy Manager System (Patent pending), a hybrid power solution that solves the energy lackage and load-shedding and permits energy savings over 90%.
EMS is a Smart Grid Node system which implements and manage energy from many different sources (solar, grid and wind power, accumulators, diesel generator and the electricity grid itself if present) and ensures a continuous supply at the most efficient and economical cost, according to customers requirements.
EMS has been developed for different corporate, commercial and civil uses such as: telecom , dairy, cold chain, petrol stations, bank branches, schools, refectories, submersible pumps, houses and condominiums, street lights, etc.
The adoption of the EMS together with energy conservation solutions, permits a substantial improvement on the quality of life, an incredible reduction of costs and helps the environment at the same time.
SIRA designs and delivers hybrid solar solutions for power needs of M/Watt size. Its target is to drastically reduce diesel generator usage and grid electricity cost.
The Energy divison of SIRA has been established in 2005 with the aim to develop hybrid energy systems in countries where energy shortage, load-shedding and rolling blackout do not allow a normal level of life.
UP TO 100% ENERGY SAVING
SOME EMS VERSIONS
The telecommunication market is becoming more and more competitive reducing the EBIT of telecommunication companies, due to high energy cost for empowering the BTS. It’s very common, in emerging countries, to have BTSs powered partially or totally by diesel generators. This is because of grid electricity not present or unstable, due to the countries energy shortage. One of the highest OpEX components, in this situation, is the cost of energy.
SIRA EMS Telco has been designed to reduce the cost of electricity to the minimum, with a low CapEx respect the traditional hybrid systems. Using EMS it is possible to avoid totally the usage of the diesel generator, in conditions of harsh load-shedding (16 hours per day and more), using only 4 PV panels. System reliability: all silicon based switches and telecom subsystems are capable to give a full reliable power solution with the cheapest electricity cost. Performance can reach 100% of fuel saving. A so high saving is capable to transform the profit and loss of telecom companies.
EMS Telco allows an increased reliability of the communications that reaches the top of the category. Security of data and commands, sent from the central system to the peripheral systems, is guaranteed by secure protocols of communication: no data lost. No interception thanks to encryption with AES 256 bit algorithm.
EMS Telco is fully integrated with any BTS and any equipment already installed.
The continuous monitoring of the network and of each node promptly allows to intercept failures or loss of energy and to isolate one section of the network in question, thanks to the telemetry and remote monitoring system (RMCS), realized according to the encryption logic and to to data and controls security .
EMS is so powerful that, for example, we only use one third of the solar panels used by our competitors’ in their configurations:

RMCS – Remote Monitoring and Command System
– Bi-Directional communication link.
– Commands can be send to RMCS.
– Server anywhere in the world.
– Information disseminated where needed.
The platform RMCS (Remote Monitoring and Command System) offers a comprehensive system of monitoring and control for Outdoor and Indoor BTS or for the monitoring and control of any power equipment.
The RMCS is fully upgradable to Energy Manager System. Adding specific component (PV panels, etc.) and upgrading the software, RMCS evolves to a Energy Manager System (EMS), without losing previous investments. The design of EMS will be based on the real data previously gathered though RMCS.
Logs, warnings and alarms are sent through telemetry (SMS, GPRS or UMTS) to a mobile phone or a remote server according to the chosen options.
When GPRS/UMTS cannot be used, SMS fault messages are sent to 3 different numbers. In case of 2G/3G connection, all data are sent to a server having a public IP address.
Through a internet browser it’s then possible to check the overall BTS situation, warning, faults and the BTS assets.
RMCS is connected to the central server through a double SIM, with an encrypted end to end link, based on AES 256 bit encryption. It’s not only telemetry because commands can be sent to RMCS from the centre (NOC).
RMCS continuously monitor the network from the Central Server to check operational parameters, log data and to avoid data losses.
EMS for Rural Houses and Villages
|EMS rural house||KIT n. 1||Kit n. 2|
|PV panel||100 W||200 w|
|Cabinet with battery and charger||1||1|
SIRA has developed energy solutions for rural areas where commercial electricity is still missing or where the grid is totally unstable. The solutions are based on kits designed for rural houses, that include photovoltaic panels, battery, lights and fan at a very affordable price.
The versality of Sira EMS allows any kind of configuration, in term of power and energy sources that can be integrated from Full Solar to solar, wind, diesel genarator and batteries to have the least investment cost and the cheapest operating expenses.
Cost per KW can be as low as per grid utility. It can be an alternative solution to extend the grid trasmission lines to reach rural villages.
Moreover if in a second time, the village is reached by the grid utility, EMS allows the integration with the traditional electricity grid.
EMS for Dairies – Milk chiller – Cold chain
EMS for refrigeration (refrigerated warehouses, cold rooms, milk chillers, etc.) in its full-solar or hybrid version, allows total compliance with international food safety standards and reduces or even eliminates the use of the diesel generator.
With our technology, this process can now also be used and implemented by smallholder cooperatives, with the opportunity to create local development in their area and added value.
For example, one way of developing the dairy industry in rural areas is to set up milk chiller and collection centers to enable even small farmers (who own only 1 or 2 cows) to produce, store and sell milk and dairies.

Solar pumps and submersible pumps
The principle of operation is to adapt the water flow to sun irradiance.
Water can be delivered regardless of weather conditions. The VFD inverter reduces motor speed and the water flow proportionally.
Due to it, water flow is not constant during daytime and therefore a storage tank is normally required.
In case where there is no electricity, this is the best alternative to the usage of diesel generators.
When the grid is present but there is a very high level of load shedding, a hybrid solution becomes preferable. Water flow is more constant and the water quantity increases significantly.
SIRA can give the forecast of produced water per each day of the year through the usage of mathematical simulation.
The top technology of Italian pumps paired up with American motors, provides the best solution for every need from 1 KW to 45 KW.
GAS & OIL – Solar System for Corrosion Protection
Cathodic protection (CP) is a technique that allows to control the corrosion of a metal surface, so it is like the cathode of an electrochemical cell.
The cathodic protection process works by counteracting the corrosive current with the application of a reverse voltage to the tube. If a pipe is well covered it can be taken from 0.0003 mA / m2 to 1.1 mA / m2. At strategic intervals along a pipe, usually no more than twenty kilometers, the current is injected through a printed current for cathodic protection, with anodes connected to a DC power supply (ICCP).
Very often pipelines run throughout countries and go to remote areas where energy must be provided by independent systems. One possibility is the use of diesel generators, but they are difficult to maintain and are not cheap.
The best solution is to use the EMS, with or without the generator.
EMS for Banks and Commercial
Bank branches have extended business hours, often 24/7, and running costs are rising together with the costs of electricity.
During the normal opening hours the full load must be powered on, whilst in night time or during weekend and holidays only critical load such as ATM, security cameras, alarm system etc must be powered on.
In countries where there is loadshedding, business must go on even when grid electricity is OFF. Diesel generators are helpful for it but, the cost per Kw/h becomes very high.
SIRA’s process to reduce the cost of energy, consist in energy audit and energy conservation, to maintain the same functionalities at reduced power.
EMS is capable to manage normal and critical loads together with the capability of recharging the batteries (when the sun irradiation is not sufficient), through the grid electricity during hours in which electricity tariff is lower. It offers the most sophisticated hybrid solar solution able to give uninterrupted power at lowest cost.
EMS for Petrol Stations
Petrol stations have extended working hours, often non-stop. Due to the increasing cost of electricity, costs of operation are increasing accordingly.
In countries where load-shedding occurs, business must be run seamlessly even when the electricity grid is OFF. Diesel generators can help, but the electricity cost per Kw/h becomes very high.
In order to reduce energy costs, SIRA’s process of energy audit and energy conservation will allow petrol stations, such as every other commercial acyivity, to run its services also in load-shedding conditions.
A version of EMS, specially designed for petrol stations, is capable of managing normal and critical loads, together with the ability to recharge batteries through the grid electricity when sun irradiation is insufficient and during hours when electricity tariffs are lowest.
Moreover an other cost reduction can be achieved trough replacing lamps and ballasts with energy efficient lamps and electronic ballast for canopies and road lights. A great reduction of the power is accomplished, maintaining the same illumination level (Lux).
SIRA offers the most sophisticated hybrid solar and technologically advanced solution at present.
