According to the solar photovoltaic multistage voltage output controller, installation is simple, energy consumption is reduced, and cost is reduced.
Description
Technical field
The utility model is a kind of controller of photovoltaic multilevel voltage output.
Background technology
International environment, energy shortage, unusual weather conditions, each state all begins to advocate energy-saving and emission-reduction, advocates new energy technology, and solar energy is development potentiality maximum in the existing new forms of energy, and prospect is the most wide.Solar energy power generating has now obtained using widely as emerging green energy resource.
Particularly on the highway, most of highway is to connect the city to the tie between the city, the highway major part all is in the open air and the mountain area, electric load little (tens kilometers website loads are no more than 100W), pull bar wiring cost height is uneconomical, supply of electric power is very inconvenient, therefore uses with the solar powered little open-air area of electric load that is fit to very much.
Solar photovoltaic controller only provides electric pressure output 12V, a 24V, 36V, 48V at present, but the power consumption equipment electric pressure is more on the highway, controller for solar generally can't provide, need other distribution source converter, because the power supply changeover device kind is more in the market, quality is uneven, and conversion efficiency just differs, have influence on the use of power consumption equipment, install also cumbersome.
Also having a kind of in addition is exactly to be equipped with an output AC220V inverter, and all devices converts device requirement voltage to by power supply adaptor, installs simple.But the inverter conversion efficiency is about about 80%, and other power supply adaptor conversion efficiency is not high yet.Direct current is delivered stream like this, and exchanging changes direct current again, causes the very big loss of energy.、
Controller for solar generally can't provide multiple voltage output in the prior art, needs other distribution source converter, because the power supply changeover device kind is more in the market, quality is uneven, conversion efficiency just differs, and has influence on the use of power consumption equipment, installs also cumbersome.
Also have a kind of technical scheme to be equipped with a voltage output exactly in addition, mix an output AC220V inverter again, all devices converts device requirement voltage to by power supply adaptor, installs simple.But the inverter conversion efficiency is about about 80%, and other power supply adaptor conversion efficiency is not high yet.Direct current is delivered stream like this, and exchanging changes direct current again, causes the very big loss of energy.
The utility model content
For overcoming the problems referred to above, the utility model provides a kind of controller of photovoltaic multilevel voltage output.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of controller of photovoltaic multilevel voltage output comprises
A solar cell interface is connected with solar panel;
A storage battery interface is connected with storage battery;
Several loading interfaces, each loading interfaces is connected with a load;

Described loading interfaces is at least 3.
The output interface of described loading interfaces comprises at least one DC24V interface, at least one DC12V interface and at least one DC5V interface.
The transformation module of the several plug types of the utility model conceptual design, be optimized combination, and the transformation module all is integrated in the solar charging/discharging controller, can change this module according to the equipment needs, this kind scheme is installed simple, only the device power supply (DPS) line need be connected on the correspondent voltage interface to get final product.Realization is installed simple and is cut down the consumption of energy.
The beneficial effects of the utility model are:
1, equipment is installed simply, does not need a lot of power supplys in the distribution box, does not also just need a lot of lines, just can be during installation because of too much line, and cause circuit messy and reduce the probability of wrong line.
2, energy consumption reduces, and requires to select whether be with the isolation transformation according to power consumption equipment, to reach the reduction loss of power.
3, reduce cost, reduced power line and power module the shell cost, reduced because the cost of labor that wiring error causes.
