In addition to the DC-AC conversion function, the solar grid tie inverter shall also own the solar cell array MPPT function and various protection function. The solar cell array delivers power energy to the power grid through sine wave PWM inverter. The power sent from the solar on grid inverter to power grid is determined by the solar cell array power and local sunshine conditions of the specific time. Now, power inverter technology becomes very mature. The work principle: When the power supply of the utility grid is stopped, the grid side will stay in short-circuit status. At this time, the grid tie solar inverter will start self-production function because of the overload problem. When the overload situation is detected by the microprocessor, it will block the SPWM signal and will trigger the circuit breaker connected with the power grid. If the solar cell array can output energy, grid tie solar inverter will operate separately, which can be controlled easily. It only needs to know the negative feedback status of the AC voltage. The microprocessor will detect the output voltage of solar grid tie inverter and compare it with the reference voltage (normally is 220V). Then, it will control the PWM output duty cycle to realize inverting and stable-voltage operation.
What is the difference between power inverter and frequency inverter? The detail analysis of inverter and frequency inverter is as following.
What is a power inverter?
Power inverter is a device that can convert DC (the battery and accumulator jar) into AC (normally the sinusoidal wave of 220V and 50Hz). It is composed of inverter bridge, control logic and filter circuit. In fact, it is a voltage inversion process with the adapter. The adapter converts the AC voltage of the mains power grid into a stable 12V DC output, while Inverter converts the 12V DC voltage output by the Adapter into high-frequency high-voltage AC. Now, the inverters generally use PWM pulse width modulation technology to obtain high-power, high-efficiency AC inverter output.
The working conditions of centrifugal pumps are generally harsh. Affected by environmental conditions, mechanical vibration and other factors in the working process, its technical status will undergo different changes. The maintenance of the water pump is to tighten and adjust the place that should be tightened and adjusted before the normal technical state of the unit itself is damaged. In addition, it is necessary to change the lubricating oil promptly to maintain normal lubrication conditions; frequently observe various instrument monitoring devices. If any problem is found, the fault should be eliminated in time, so that the unit is always working in good technical condition. Only in this way can the service life of the water pump unit be prolonged and the unit can work with high quality and high efficiency.
Small-scale Technology Certificates (STCs) play a vital role in the renewable energy sector, especially in countries like Australia, which are advancing renewable energy adoption. STCs provide financial incentives for households and small businesses to install solar systems and drive the rapid growth of the entire renewable energy industry. This blog will comprehensively explain the definition, functions, application process, recent policy changes, and market impacts of STCs to help readers thoroughly understand this critical concept.
As the threat of climate change intensifies, governments worldwide have established ambitious renewable energy goals. These goals aim to reduce reliance on depleting fossil fuels and monitor and oversee the energy market, quantifying the carbon dioxide (CO₂) reduction benefits of solar power systems and other renewable energy installations. Small-scale Technology Certificates (STCs) hold a prominent position among the many policy tools linked to renewable energy. This blog delves into STCs, highlighting three key aspects you need to know.
As the global demand for renewable energy continues to rise, more households are opting for solar photovoltaic (PV) systems to reduce electricity bills and minimize their carbon footprint. Specific metering methods are used to track interactions between solar energy generation and grid electricity when connecting a solar PV system to the power grid. The two primary methods are Net Metering and Gross Metering. In this article, Home Power Inverter will explore how these two metering systems work, their advantages and disadvantages, and how to choose the best option for your needs.
Over the past few decades, solar technology has evolved rapidly, emerging as a reliable, eco-friendly, and economically viable energy choice. For residential users, installing a solar energy system not only reduces electricity costs but also increases property value and lowers the household’s environmental footprint. In today’s blog, Home Power Inverter will delve into the numerous benefits that solar energy brings to households and analyze its positive impact on the economy, the environment, and lifestyles. This article will provide a detailed explanation of how solar energy systems work and outline seven key benefits, offering readers a comprehensive understanding of the remarkable value solar power can provide for homes.
After installing the solar system, your electrical energy meter will need to be changed to accommodate the new installation, and the question is; who will be responsible of such changeover? Is it you or solar installation company or electricity company? This point must be clear from the beginning, and usually the solar company will do that job under the supervision of the electricity company.
The solar system rebates that you will get from the solar installation company as a result of selling your STCs certificate is an important point to be discussed, so you will be aware of how mush discount you will get from such STCs certificates.
