PWM Regulator

Wholesale PWM Regulator (solar charge controller)

Pulse width modulation (PWM) regulator is essentially a switch(aka. Solar Charge Controllers) that connects a solar array to a battery. The result is that the voltage of the array will be pulled down to near that of the battery.

PWM is arguably the most effective means to achieve constant voltage battery charging by switching the solar system controller’s power devices. When in PWM regulation, the current from the solar array tapers according to the battery’s condition and recharging needs.

Advantages of PWM Charge Controllers for PV Systems?

Charging a battery with a solar system is undeniably a difficult challenge.

In the past, simple on-off regulators were used to limit battery outgassing when a solar panel produced excess energy. However, as solar systems matured, it became clear how much these simple devices actually interfered with the charging process.

The history of on-off regulators has been full of battery failures, increasing load disconnects, and growing user dissatisfaction. PWM has recently surfaced as the first significant advance in solar battery charging.

PWM regulators make use of technology that is similar to other modern high-quality battery chargers. When a battery voltage reaches the regulation setpoint, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery — and yet the charging continues to return the maximum amount of energy to the battery in the shortest time. The result of this is a higher charging efficiency, rapid recharging, and a healthy battery at full capacity.

Additionally, the PWM charge controller promises some very interesting and unique benefits. These benefits include:

  1. Ability to recover lost battery capacity and de-sulfate a battery
  2. Dramatically increase the charge acceptance of the battery
  3. Maintain high average battery capacities (90%–95%), compared to on-off regulated state-of-charge levels that are usually 55%–60%
  4. Equalize drifting solar battery cells
  5. Reduce battery heating and gassing
  6. Automatically adjust for battery aging
  7. Self-regulate for voltage drops and temperature effects in solar systems

A great deal of testing and data supports the benefits offered by PWM regulators. Additionally, manufacturers are continuing their own ongoing test programs to refine the PWM charging technology. As a result, over time, each of these benefits will undoubtedly be improved and more clearly defined.

Are All PWM Chargers the Same?

Many solar charge controllers that simply switch FETs differently than the on-off algorithm claim to be PWM regulators. Buyers should be aware of this because this is actually not true. Only a few controllers are actually using a PWM constant voltage charging algorithm. The rest are switching FETs with various algorithms that are cheaper and less effective.

Manufacturers

In the simplest terms, manufacturing is the process of producing actual goods or items/products through the use of raw materials, human labour, use of machinery, tools and other processes such as chemical formulation. This process usually starts with product designing and raw material selection, turning them into an actual product output. 

Solar Products Manufacturers and Factories

In terms of solar, manufacturing encompasses the fabrication or production of materials across the solar market chain. The most common product being manufactured by solar companies are the solar photovoltaic (PV) panels, which are made with several subcomponents such as solar wafers, cells, glass, back sheets, and frames. Before a solar panel comes into life, it will undergo a lot of processes, from designing, modelling, choosing what raw materials to use and then assembling them all to make the final product.

More Than Just Solar Panels

Aside from the solar panels, solar companies have many other manufactured products that are required to make solar energy systems work smoothly, like solar inverters, batteries, combiner boxes, and racking and tracking structures.

Having a solar manufacturing sector makes a big difference in supplying affordable solar energy in different areas. Aside from maintaining the rising domestic and global demand for cleaner and renewable energy, they also help the economy grow, particularly the solar industry. If you are in search of a reliable solar manufacturing company, checking out our solar outsourcing company, SolarFeeds, would help you get easy access to reliable information, news, data and a list of solar manufacturers that can help you with solar products.

Solar Market Outlook in Russia

There is a renewable energy drive going on in Russia right now and solar energy is leading the way for renewable sources. At the end of 2019, the country reached a PV capacity installation of 1.7 GW. This came as a result of the Russian government’s grid-connected projects that launched in 2014.

The Russian government tendered another 500 MW of solar capacity in 2020. This is just one part of the country’s continued effort to deploy solar energy systems and reach its target of 7 GW in solar energy by 2035.

In particular, the Russian government is accelerating its efforts at PV and solar installations in areas that are disconnected from the CSA grid. They believe that these areas have the highest potential for solar projects due to limited access to transport infrastructure and energy sources.

With full support from the Russian government through the enactment of the renewable energy law, it is expected that the renewable energy sector will create an attractive business environment. The Russian government is specifically looking to attract local and international clean energy investors, such as those willing to put up solar power plants in the country. 

Solar Energy Equipment Supply Capacity in Russia

Russia is one of the top countries in terms of renewable energy production. It is one of the top producers in the EU and the rest of the world. 

Therefore, there is a wide array of equipment suppliers and distributors in and out of Russia for those looking to make solar installations. 

Top 8 Major Seaports & Logistics in Russia

For those looking to invest in solar power equipment, Russia is home to a vast logistics industry and they have several major seaports.

The major seaports in Russia are Saint Petersburg, Vladivostok, Novorossiyk, Kaliningrad, Sosnogorsk, Privolzhsky, Pavlovsk, and Pyatigorsk. The aforementioned are some of the busiest ports in Russia and in Europe.
