Description

Electric bill saving equipment.

SECTOR OF THE TECHNIQUE

It applies to family electrical installations or small businesses. Use accumulators, DC and AC converters and eventually solar panels.

STATE OF THE TECHNIQUE

In the market there are components to manufacture this utility model. He

team assembles existing components for a new function. For the convenience of power generators, nighttime energy consumption can be much cheaper than daytime consumption. Usually this electrical energy is consumed immediately or accumulates in the form of heat for heating purposes.

The extension of the use of solar panels as power generators has favored the development of voltage converters from high quality alternating current to direct current.

Some teams do similar work such as uninterruptible power supplies (SAI) that serve to keep critical equipment running before power outages.

The design of this model is to use components of these equipment to save on the electricity bill, consume electricity that has accumulated at a lower cost, especially at night and eventually with solar generation.

EXPLANATION OF THE INVENTION

The invention is a device that charges batteries with energy that come from the electricity network at a reduced rate (night or valley rate) and delivers it as a low voltage alternating current supply (the most typical 50Hz -230V) when required for the consumption.

The equipment additionally supports recharging the batteries using solar panels. The shape of the equipment is also important because a size compatible with a low-appliance appliance (type washing machines or dishwashers) has been used so that it can be installed using holes that are usually included in the design of the homes or integrated into the usual furniture of a kitchen or laundry.

The purpose of development is to unify in a team systems that allow obtaining energy for final use, at the lowest possible price, integrating both technical advantages, such as the use of solar panels and administrative advantages, such as the nightly rate, in a unique and simple equipment to install and automated so that it does not require a Supervision by the end user.

The use must allow a continuous supply of energy, using the available sources in order of cost. The economy must be visible to the user, so that the user Know the performance of the team.

The equipment receives power from the network with a specified schedule, for which it needs a

programmer that automatically starts loading mode. The power is received at an alternating mains voltage (230V AC) and must be converted to the Continuous battery voltage.

Batteries must also be managed to respect their charging parameters- discharge. The charging and discharging modes depend on the type of batteries and their Conservation requires scheduled equipment.

The energy stored in the batteries must be converted to alternating voltage with

quality homologated to the network and poured into the interior installation. When lowering the charge of the batteries the power must be supplemented directly of the network without the user noticing the change.

MODE OF REALIZATION

The components are described to demonstrate that the invention is developed and is functional although similar utility can be achieved with other brands or models. Likewise, the aforementioned parameters can be adapted to the needs of the service, adjusted to the state of the art and serve as an existing supply in the market.

The equipment is mounted on a metal chassis (1) that has four adjustable legs (2) to ensure its stability and allow it to adjust to the uneven ground.

The chassis is divided into trays in which the following equipment is mounted. The power converter (3) is STUDER brand Xtender XTM 3500-24 model that can treat 3500 W from 230V AC to 24V DC and vice versa. STUDER programmer (4), model RCC-02. This programmer is the one who decides the mode of consumption and manages the charge of the batteries and also has an informative screen that indicates the type of energy that is being consumed at all times. The four batteries (5) selected are GEL or AGM (AGM is the abbreviation of Absortion Glass Mat) 4 modules of Victor Energy brand model GEL 12-220 are used with the capacity to accumulate 10.5 KW-H (12V x 220A- H c / u) Electrical panel (6) with the regulatory protections. Also included in this table is a switch that allows you to manually select the direct power supply of the network or the power supply through the

automatic equipment management.

The connection bars (7) allow the entry and exit of energy. In these

connection bars are given input to mains voltage and solar panels and given

5 output to consumption.

Once the components are assembled and properly wired, the entire assembly is enclosed by placing metal covers so that the final appearance is that of Figure 1. The recharging of batteries by solar panels is done through a battery charging module brand TRISTAR MPPT model TS-MPPT-60. (This is not included

10 in the figures as it is mounted separately). The power is selected according to the requirements of a housing type so 3500W is selected

To show that it can be installed in the usual space of an appliance, the dimensions are indicated in Figure 1.

15 Functional equipment has been manufactured and tested successfully.
