HIM – Hybrid Integrated Module

HIM consists of a variable speed DC generator which charges a battery bank in cycling mode and powers the load at the same time. Due to its battery cycling concept it’s possible to reach a fuel consumption rate of only 0,4 lt/kWh even for very low load demand.

  • Best fuel consumption rate even at the lowest power demands
  • Integration with Grid and PV panels
  • Possibility to program engine off periods during night hours
  • Residual battery autonomy in case of engine failure

STANDARD CONFIGURATION

Features
Fuel consumption

Due to the high efficiency given by its variable speed DC generator, the system is able to achieve great savings in terms of fuel consumption. For a BTS site having 1 kW as average load, the fuel consumption is below 10 liters/day,  representing a saving up to 72% when compared to a conventional AC generator.

Refueling

Thanks to the significant reduction in terms of fuel consumption and to the big capacity of the fuel tank provided with the unit, the system allows to achieve an autonomy of 150 days in case of BTS having 1 KW as average load, meaning a saving up to 80% in the number of refueling trips to site.

Running hours

The system, being based on a cycling operation modality between generator and batteries, allows the engine to run only a few hours per day and to increase the genset life cycle before overahual. In case of a 1 kW BTS site, engine runs only 4 hours per day, taking engine lifetime up to 12 years.

Maintenance

The system has been developed to increase the maintenance interval up to 1000 engine running hours. In the case of BTS with 1 KW average load, the ordinary maintenance activities are made every 8 months, allowing an 85% saving in terms of number of trips to site for maintenance.

Batteries

Li-ions technology represent the future for the CDC operation modality in powering BTS sites. These batteries are 100% maintenance free and they allow fast charge, the highest number of cycles in the market and a remote monitoring through their own BMS. Additionally, being each of them at 48V, they work in parallel operation, so, if any failure happens on one single battery, the other batteries will be still functioning, guaranteeing the efficiency of the system to be kept always constant.

Life Cycle

The cycling operation modality allows to increase the engine lifetime and consequently the whole system life cycle, being capable to get it extended up to more than 20  years in the case of 1 KW average load on site, doing one single main overhaul during the period.

Payback

The great savings in terms of OPEX allow to get a very short payback even for this latest high level of technology, which in most of the cases is expected to be within 2 years from commissioning.

TCO

The daily Total Costs of Ownership of the HIM system are the lowest in its category and can allow a reduction up to 60% if compared to a conventional AC generator powering  a 1 kW average load BTS.

Unnecessary Hardware

Being a Plug&Play solution equipped with batteries and providing power both in DC and AC, additional savings can be achieved thought the elimination of  AC/DC rectifiers and battery bank existing on site. Moreover, since even at the hottest climate condition the system can preserve its battery bank through the activity of its passive cooling system, further savings can be achieved by the elimination/reduction of the A/C systems installed on site, with following improvements in total power and fuel consumption for that site.

Anti-theft protections

Due to the experience acquired on the field by the producer, the unit has been equipped with high technological devices to obstacle any possibility for fuel stealing and to duly inform the relevant NOC for any attempt done on the unit with such an aim.

Remote Control

Being developed for powering off/bad grid sites, which are often located in remote areas difficult to be reached, the Module can be monitored and controlled from a remote station via GSM/GPRS/IP connection. All the alarms and events report are also accesible by remote and this allows an easy scheduling of all the operational activities

Noise Level

In urban areas the noise level regulation might be very strict and Operators can be complaint by installing HIM on such specific sites. In fact, the soundproofed canopy of the HIM guarantees a max noise level of 60 db(A) at 7m when engine is running.

Environmental care

The cycling concept and the variable speed technology of its engine allow the HIM to reduce the carbon footprint up to 70%. Additionally, the easy integration with Renewable Energy Sources gives the Module a "green" approach towards the environemental sustainability. Last but not least, the use of a lead-free technology and a 100% double wall fuel tank, prevent from the risk of environmental pollution.

Optimized configuration

The Module has been designed for hot swap on site and for being scalable according to Client changing requirement. Its reduced footprint, light weight and low noise level allow installation also on rooftop sites, where others cannot. Additionally, its modular structure along with its overall dimension allow easy handling and best fitting for FCL shipment.

CONFIGURATION WITH SOLAR CONNECTION

Features
Solar contribution

When the HIM is equipped with the PV Panels Connection kit, the energy contribution provided by the solar plant is used to charge the batteries and to power the load at the same time. When the solar energy is not enough, the DC generator automatically starts and regulate its speed to provide the exact quantity of energy which is missing from the PV panels. Different from other hybrid solutions which are simply switching from one source to another one, not utilizing the total energy produced by the available installations, the HIM Solar is cabable of parallelling operation between DC generator and PV panels, which jointly work to keep the BTS always powered.

Fuel consumption

Due to the high efficiency given by its variable speed DC generator, the system is able to achieve great savings in terms of fuel consumption. For a BTS site having 1 kW as average load and a 1,5 kWp solar power plant, the fuel consumption is 7 liters/day,  representing a saving up to 80% when compared to a conventional AC generator.

Refueling

Thanks to the significant reduction in terms of fuel consumption and to the big capacity of the fuel tank provided with the unit, the system allows to achieve an autonomy of 205 days in case of BTS having 1 kW as average load and 1,5 kWp of solar power plants installed on site, meaning a saving up to 85% in the number of refueling trips to site.

Running hours

The system, being based on a cycling operation modality between generator and batteries, allows the engine to run only a few hours per day and to increase the genset life cycle before overahaul. In case of a 1 kW BTS site and a 1,5 kWp solar power plant, engine runs only 3,3 hours per day, taking engine lifetime up to 15 years.

Maintenance

The system has been developed to increase the maintenance interval up to 1000 engine running hours. In the case of BTS with 1 kW average load with 1,5 KWp of PV panels installed on site, the ordinary maintenance activities are made every 10 months, allowing a 96% saving in terms of number of trips to site for maintenance.
