Photovoltaic inverter  Photovoltaic inverter (PV inverter or solar inverter) is an inverter that converts the variable DC voltage generated by photovoltaic (PV) solar panels into mains frequency alternating current (AC), which can be fed back to the commercial power transmission system or supply and disconnect Grid use of the net. Photovoltaic inverter is one of the important system balance (BOS) in photovoltaic array system, and it can be used with general AC power supply equipment. Solar inverters have special functions that cooperate with photovoltaic arrays, such as maximum power point tracking and islanding protection.Solar inverters can be divided into the following three categories:1.Stand-alone inverters: Used in stand-alone systems, the photovoltaic array charges the battery, and the inverter uses the DC voltage of the battery as its energy source. Many stand-alone inverters also integrate a battery charger, which can charge the battery with AC power. Generally, this kind of inverter will not touch the grid, so it does not need islanding effect protection function.2.Grid-tie inverters: The output voltage of the inverter can be fed back to the commercial AC power supply, so the output sine wave needs to be the same phase, frequency and voltage as the power supply. The grid-connected inverter will have a safety design. If it is not connected to a power source, it will automatically turn off the output. If the grid power supply trips, the grid-connected inverter does not have the power supply function.3.Battery backup inverters are a special kind of inverters. The battery is used as its power source, and the battery charger is used to charge the battery. If there is too much power, it will be fed back to the AC power source. This kind of inverter can provide AC power to the specified load when the grid power is tripped, so it needs to have an islanding effect protection function.

Solar photovoltaic is a new guarantee for EnterprisesThis year, due to the disorderly and illegal use of energy by some key energy-consuming enterprises, energy-saving measures in various regions are in a severe situation.Due to the shortage of power supply, more than 10 provinces have successively issued notices of "power curtailment and shutdown". The power curtailment policy brought by the "dual control" to enterprises, coupled with the resurgence of the epidemic, will have a heavy blow to the production chain of enterprises and the local and national economies. The key to achieving the goal of carbon peak and carbon neutrality is to replace traditional technologies with green technologies to reduce carbon emissions. In fact, the "dual control" goal corresponds to higher-quality development.At present, many high energy-consuming enterprises choose to use clean energy while improving their own efficiency, and directly use the green electricity produced by the factory buildings. Distributed photovoltaics on the roofs of enterprise factories are currently the most direct and convenient form of clean energy utilization. It can not only provide clean photovoltaic power to enterprises, but also bring certain economic effects to enterprises through the Internet. As the country attaches great importance to reducing energy consumption, policy standards will be strict year by year. and the use of photovoltaic power will Effectively reduce the carbon emission level of emission control companies.Distributed photovoltaics mainly have the following four advantages:1. Reduce the energy cost of enterprises and relax their energy use restrictions. 2. Save peak electricity bills and sell surplus electricity online For high-energy-consuming production enterprises, installing photovoltaic power plants can save a lot of electricity expenses, and even make a profit. For production companies that are striving for division, the yield of photovoltaic power generation is higher than that of many traditional production companies. Photovoltaic power generation not only solves the company's own electricity problem, the additional power generation can also create new economic benefits for the company. 3. Promote energy saving and emission reduction, and produce good social benefits 4. Heat insulation and cold protection, increase environmental comfort Photovoltaic panels have the function of heat insulation. After photovoltaic modules are placed on the roof, the temperature of the downstairs factory can be effectively reduced, while the comfort of the workers in the factory can be ensured, and the smooth operation of production equipment indirectly reduces the cooling of the enterprise. cost. The state adopts "dual control" of energy consumption, not only to encourage the use of green electricity, but more importantly: strictly control the intensity of energy consumption, force adjustments in the industrial structure and energy structure, and guide the high-quality development of the local economy.

In our daily life, we often touch with lithium batteries, gel batteries and lead-acid batteries. What are the differences and advantages and disadvantages between these three?       The difference between lithium battery and gel battery①Environmental protection: The lithium battery of the solar street lamp is no pollution; The gel battery is polluted by heavy metal lead.②The electrolyte is different: the electrolyte of the lithium battery is a non-aqueous liquid organic electrolyte; the electrolyte of the gel battery is a gel electrolyte.③Long life Spain: The current lithium iron phosphate charge is 1500 times, no memory effect, about 85% of the storage capacity after 1500 times of charge; while the gel battery is about 500 times, the memory effect is obvious.④Safety: The difference in the safety of power lithium battery materials is that the gel battery technology is quite mature, and the safety is higher than that of lithium batteries.⑤High efficiency and good performance: The small self-discharge of the colloidal battery is good for long-term storage; the high deep discharge performance is good for improving the utilization rate and discharge capacity of active materials; the recovery ability of deep discharge and discharge is strong, and the charge acceptance ability exceeds the national standard by more than 50% . Which is better, gel battery or lead-acid battery?Lead-acid batteries include gel and liquid. Gel batteries have strong cold resistance, and their working energy efficiency is far better than liquid batteries below minus 15 ℃. Its heat preservation performance is excellent. If you live in a place with very low temperatures in winter You can choose gel batteries The performance of the gel battery is better than that of the lead-acid battery. The gel battery has stable performance, high reliability, long service life, strong adaptability to temperature, long-term discharge ability, cyclic discharge ability, overcharge and over discharge self-protection Etc. The above is the difference between lithium batteries and gel batteries and which is better between gel batteries and lead-acid batteries. The emergence of lithium batteries is a manifestation of the progress of the industry. All our lighting products also use lithium batteries, which are more durable and efficient.
