Zero grid energy generators are available on the Brazilian market

The off-grid system is a solution used in regions where there is no service from concessionaires, in addition to functioning as a backup for on-grid systems, either to enable consumption at peak times or to protect photovoltaic installations against surges and failures. of supply. 

With the expansion and consolidation of the photovoltaic market, more and more companies have applied this type of solution, even in hybrid systems.

Aiming to meet this demand from the solar energy sector, the distributor Aldo Solar, in partnership with the manufacturer Growatt, a company that has stood out in innovation and technology investing every year 10% of revenue in R&D, will make available three-phase 380 V generators developed to connect to the grid with zero injection.

The equipment allows load management, controlling the flow of energy and enabling the grid zero function. With this, it is possible to manage the energy produced by the photovoltaic system, avoiding injection into the grid or controlling the capacity that can be injected.

The user can direct the energy produced in a grid zero system to the demand of a specific distribution board or for several specific activities.

These are intelligent systems that control generation according to the needs of loads/consumption and, at the same time, not allowing feedback from the grid. The generators come with a Growatt zero smart grid energy meter for input standards of 100 KW, 300 KW or up to 600 KW / 1200A.

applications

Some examples of applications are:

• dual on-grid with grid zero for medium and large projects without the need to increase the demand contract with the concessionaire;
• installations in areas where the concessionaire does not allow injection into the grid;
• large applications from free market users;
• supply of an air conditioning plant;
• diverse applications for agribusiness and industries, without the need for projects and changes to contracts with the energy concessionaire.

Aldo Pereira Teixeira, founder and president of Aldo Solar, highlights that grid zero generators reinforce photovoltaic solar energy's commitment to being a clean and cheap source. It also exemplifies the positive impact of applying generators.

“A good practical example is our headquarters in Maringá. In 2017, we installed the on-grid solar energy system with interaction with the public grid. However, our company grew and with it our energy bill and, to reduce costs, we have now installed a 100 kW Growatt zero grid system and direct all energy generated to the general framework of the air conditioning system. With this, we have already managed to reduce energy bill expenses, without the need to increase the demand contract”, said Teixeira.

On-grid and off-grid systems

In the on-grid mode, the system is connected to the public electricity network and, when the unit generates more energy than necessary, the surplus is inserted into the concessionaires' system and converted into energy credits that will be deducted or accumulated in the utility bill. light at the end of the month. Off-grid systems are isolated systems not connected to the electrical grid and are used to store solar energy using batteries.
