Product Description:

A solar inverter, or PV inverter, or Solar converter, converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network.

It is a critical BOS–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment.

Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.

Q:What is the system voltage of solar panels
System voltage refers to the number of solar panels composed of a solar power generation system, the maximum DC voltage of the power system.
Q:I want to install a full set of domestic solar heating equipment does not know how much money to spend, please.
Save 50% equivalent to an annual savings of more than 3300 heating projects; water consumption in accordance with an average of 200 liters a day, remove the winter has been deducted 120 days, the remaining 240 days probably with hot water total: 48 tons, natural gas energy is calculated according to the cost of the cheapest words per ton of hot water heating costs 15 yuan, annual water savings of 720 yuan. Two of the total savings of 4000 yuan, according to the energy prices coefficient is estimated at less than 10 years to recover the full investment, another ten years of savings more than 40 thousand yuan.
Q:How about the price of solar power generation system
Photovoltaic power generation system can not buy cheap, cheap product quality is not good to use expensive. Photovoltaic power generation system can be used to invest in financial products, general household photovoltaic system 7~9 can recover the cost of power system can be used for more than 25 years, 25 years after the power attenuation of about 20%, if the poor quality of the products are generally 2~3 years can be reduced by 20% and must keep their eyes open several more formal manufacturers so when buying light V system, quality quality assurance production factory.
Q:Solar power generation system installation which precautions, ah, there is a need for special attention
Solar power system consists of solar panels, solar controller, battery, inverter and other load. Solar power system installation note has the following 1, the battery plate array need to consider the installation azimuth angle, tilt angle. 2, to avoid blocking between the panels. Including the surrounding buildings (poles, building eaves, etc.). 3, stent placement stability and firmness. 4, the distance between the line and the bus box location. Try to walk a short distance and average. 5, related accessories to meet the system requirements (such as wiring column, with wire diameter etc.). 6, the terminal should be firm, to prevent the virtual connection or disconnection.
Q:Solar photovoltaic system
State subsidies for distributed PV policy: distributed generation price subsidies by 0.42 yuan / kWh (subsidies for a period of 20 years), distributed photovoltaic power generation system of power grid, power grid enterprises in accordance with the local coal-fired power by electricity (0.44 yuan /kWh) acquisition.
Q:What are the main features of solar photovoltaic systems
Compared with the commonly used thermal power generation system, the advantages of photovoltaic power generation:No danger of depletion; safe and reliable, no noise, no pollution, absolutely clean (pollution-free); not subject to geographical distribution of the resources, can take advantage of the building roof; for example, areas without electricity, and complex terrain area; no fuel consumption and the erection of transmission line can be on-site power supply high quality energy;; users emotionally receptive; the construction period is short, get energy to spend a short time.
Q:Solar power generation system how to choose?
Solar power generation technology is now very mature, the most important choice is to generate sufficient power, stable operation, reliable warranty and after-sales service.
Q:Household solar photovoltaic power generation system connected to the grid, how much money?
General installation 3000W on the line, a full set of system down 21 thousand yuan. Print-Rite used solar panels, inverter with crystal fuyuan. Guilin Jinyang PV is so safe.
Q:What are the devices needed for PV systems?
Solar cell array. The solar cell array is composed of a solar cell composite plate and a square bracket. Because the single voltage of solar cells is generally low, so usually they are connected in parallel and series solar panels have practical value, as an application unit, and then according to the power requirements of a plurality of application unit series and parallel composition of solar cell array. Solar panels (some semiconductor materials, mainly polysilicon and silicon and amorphous silicon, through a certain process to assemble) is the main component of the solar photovoltaic system, the highest value is also part of the solar photovoltaic power generation system. Solar panels in the light of the circumstances, the battery absorbs light energy, the two ends of the battery appears to be the accumulation of different charges, that is, the light generated voltage, which is the "photoelectric effect". Under the action of the photoelectric effect, the electromotive force is generated at both ends of the solar cell, and the light energy is converted into electric energy.
Q:What are the advantages and disadvantages of small-scale solar power generation system?
There are intermittent and random ground application, power generation and climatic conditions in the night or rainy days have little or no power; lower power density, under standard conditions, the solar radiation intensity on the ground received for 1000W/M^2. Large scale use, the need to occupy a larger area; the price is still more expensive, for conventional power generation 3~15 times, the initial investment is high.
