Energy Storage System

Frequently asked questions

What is an energy storage system?

A BESS (Battery energy storage system) also called "Battery pack" is made up of a set of batteries and an inverter system. The first ones are the responsible to store the energy and normally we measure it in kWh, and the second ones provide the amount of maximum power (kW) you can deliver. For example, if we have a remote telecom application with a load (perhaps an antenna) of 1,5 kW, with our ZBE45 that can store 36kW we will have an autonomy of: 36/1,5= 24 hours. This models’ maximum output power capability is 15kVA (or 12 kW with a pf=0,8), so connecting a load or several loads of this amount, we could provide: 36/12= 3 hours autonomy maximum.

How energy storage system works

There are 3 main ways of using a BESS in different applications (events, constructions, industrial, domestic…). The most obvious one is island, if you need a zero emissions or zero noise energy source, for instance a small event in the city center, with low loads (lightning, music devices…) you can use just one of our ZB models with available connections in 3ph or single phase. Once is not needed it can be recharged with the mains using its Parking mode with a small consumption of energy If you have a bigger extension like an agriculture application, where you can place solar panels, you could use a BESS to for example feed the irrigation system that will water the crop. Once it is not needed anymore, the batteries can be recharged with solar energy, making this a complete sustainable solution with Zero emissions. And last one in a hybrid solution with a generator. A BESS will improve the performance in an application like a construction site, while feeding low loads during nights with the batteries or supplying extra power in critical moment. The BESS will get recharged with the generator in the most efficient moments, to make sure the engine is running in an optimal working point and batteries are fully recharged when needed.

solar panels in field
If you have a bigger extension like an agriculture application, where you can place solar panels, you could use a BESS to for example feed the irrigation system that will water the crop. Once it is not needed anymore, the batteries can be recharged with solar energy, making this a complete sustainable solution with Zero emissions.
HYBRID Mode
