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:
- Ability to recover lost battery capacity and de-sulfate a battery
- Dramatically increase the charge acceptance of the battery
- Maintain high average battery capacities (90%–95%), compared to on-off regulated state-of-charge levels that are usually 55%–60%
- Equalize drifting solar battery cells
- Reduce battery heating and gassing
- Automatically adjust for battery aging
- 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.

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.
A Snapshot of the Norwegian solar market
Norway is situated far north of the globe meaning it does not receive as much sunlight as most nations. A significant proportion of the country’s energy stems from hydro. Still, it has made huge strides in adopting solar energy even though its lunar resources are limited. According to a recent report, there is a considerable rise in public support for the Norwegian solar industry.
As of December 2019, Norway had a cumulative installed solar capacity of 120 Megawatts. This capacity came into being through the addition of 51 Megawatts, the highest added capacity in a single year. Commercial and industrial installations made up 60% of the additional solar capacity while residential installations came second with 35%.
Norway’s estimated installed solar capacity in 2020 was 152 Megawatts. This reveals that the Scandinavian country’s solar capacity is growing steadily along with its solar market. What does this mean for you as a solar installer? Well, lucrative opportunities tend to sprout up as any market continues to grow.
Solar equipment production and supply capacity in Norway
The Norwegian solar market enjoys a healthy presence of solar equipment manufacturers and distributors. They deal with the supply of solar panels and several other components. Do you need a trustworthy supplier for your current or next project?
