Year 4500 tons of standard coal saving, total carbon dioxide emissions of 11200 tons, 340 tons of sulfur dioxide emissions and nox emissions of 170 tons and 3000 tons of carbon.

While environmental protection environment,solar power inverter will effectively ease the local energy supply tension, power inverter with charger play a positive role in order to speed up the local industry structure adjustment.

Water-saving: "power inverter with charger" to realize zero discharge of sewage
Foshan factory in the beginning of construction,power inverter with charger in wastewater treatment has set up a new model for the industry.

The factory drainage by wind turbine inverter  system.

Factory sewage depth processing, meet the national sewage recycling related standards before the part back to campus afforestation,wind turbine inverter the remaining pool access to production,wind turbine inverter as production, such as toilet flushing water.

Water reuse system can day processing 1870 tons of production and living sewage, truly achieve the sewage collection, treatment and recycle of "zero emission", for China's sustainable economic development devoted himself to the silly art of gossip.

Saving material, saving start with each lamp
Foshan factory in the planning design of daylighting skylight, make full use of natural light to illuminate the building interior,wind turbine inverter save a lot of lighting equipment, lighting and electricity.

In LED lamp, metal halide lamp, mercury free, such as high efficiency and energy saving fluorescent lamp, solar street lamp lighting system,wind turbine inverter under the application of the material saving start with each lamp.

Environmental protection: the employees are more "love"
As a manufacturing enterprise, faw - Volkswagen attaches great importance to the production management of employees, production units adopt green production process.

Hooked up to the problem of distributed photovoltaic (pv) power inverter with charger also is able to "last year

Following the end of October last year, state grid (microblogging) published the opinion on distributed grid tie inverter  (pv) service, aimed at clearing the 10 kv and below problem of voltage grade in power grid tie inverter distributed grid tie inverter.

Distributed photovoltaic (pv) grid tie inverter "failed to sell" at this stage

However, the grid tie inverter opinions issued five months, the distributed grid-connected photovoltaic (pv) application does not see more in our country. 

Southern daily reporter according to public information statistics, there are only including Beijing, Shanghai, Qingdao, jinan, wuxi and other places there are a few people, from business application enthusiasm is not high also.

Why distributed photovoltaic power converter will appear the situation of failed to sell?

In bloomberg new energy finance analyst Wang Min nan understanding, most residents have not roof with independent property rights, and less electricity consumption, electricity price is low, and photovoltaic power converter need investment, maintenance, leads to lower construction enthusiasm.

"Distributed photovoltaic cheered don't hit, the main reason is that the state of distributed photovoltaic electricity price policy is not clear,power converter can't let people to form a reasonable and stable expectations."

 CPPCC, deputy to the National People's Congress, jiangsu variety group chairman ZanShengDa submit the Suggestions for promotion of distributed photovoltaic said in the proposal.

In fact, a distributed grid photovoltaic power inverter with charger after problem solving, electricity price subsidies to become the industry look forward to.

The good news is that recently there have been reports that the national development and reform commission has issued "notice about perfect the photovoltaic (pv) power inverter with chargerr price policy" exposure draft, among them, a distributed electricity price subsidies for 0.35 yuan per KWH.

"Mentioned in the draft only subsidies for spontaneous use KWH 0.35 yuan, 0.4 yuan to 0.6 yuan lower than market expectations, and give the same subsidies is still unclear as to whether online part."

Wang Min nan told reporters, the southern daily from rate of return, if just for spontaneous self-use of subsidies, rooftop pv power inverter with charger plant investment return period is longer than the other.

Beijing residents such as HaiHua distributed grid tie inverter photovoltaic (pv) application is the first man. 

He told reporters, the southern daily now photovoltaic roof power inverter with charger subsidies can only in accordance with 0.4 yuan settlement feed-in tariff, desulfurization of coal even though the Internet part 0.35 yuan KWH subsidy, combined with their own electricity price of 0.5 yuan, his small photovoltaic power inverter project returns need to 12 years of time.

Over-reliance on coal-fired power inverter with charger far more than prices of electricity bills

Japan fired power inverter  are operating at full capacity to compensate for the huge power inverter left by the nuclear power inverter to stop a number of old coal-fired power inverter emergency restart in the event of an accident, could trigger large-scale blackouts.

Located in Aichi Taketoyo fired power stations was established in 1972, the machine for fuel oil.

Acting Director Hori Ryuji told a news agency reporter, in October 2009, due to aging equipment, Chubu Electric Power inverter Company to stop and prepare to dismantle.

 May 2011, the Hamaoka nuclear power inverter with charger was ordered to stop, Chubu Electric Power Company had decided to restart.

By the end of July 2011, after nearly three months of hard repair, 2 Unit re-generation,power inverter with charger aging equipment is still plagued them, make it in perpetuity.

Difficult burden-renewable energy.

In this context, Japan has sights on power inverter with charger and other renewable energy sources. 

In July 2012, Japan began the implementation of renewable energy fixed price acquisition system, priced at about 2-5 times the price of sine wave inverter  or nuclear power,sine wave inverter give investors a certain profit margin. 

The Japanese government hopes to attract more enterprises to invest in renewable energy.

The solar investment soared after the implementation of this system.

According to statistics,sine wave inverter as of the end of November 2012, the installed capacity of solar power generation in Japan reached 3.26 million kilowatts, equivalent to about three nuclear power generating units, accounting for 90% of the renewable energy sources.
