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.

Solar Products Distributors
Distributors are those companies working as big warehouses that served as the middlemen between the consumer/customer and the manufacturer. Typically, in distribution, a company is handling the sourcing, stocking and logistics but nowadays they are also helping manufacturers in product designing and solving other business conflicts.
Aside from other industries, distributors also play a vital role in the solar industry. Solar distributors become long-term partners of solar manufacturing companies and even solar contractors. They are not only serving as warehouse facilities but partners that also provide strategic solutions to help solar companies achieve their desired outcomes. Solar distributors assist solar manufacturing companies by storing. handling and shipping their solar products to their buyers. On the other hand, they help solar contractor companies in outsourcing high-quality solar products.
These solar distributors are the ones who deal with homeowners who want to go solar, businesses that work with the solar industry and solar installers who offer solar system services to both residential and commercial customers. But on top of that, the solar distributor’s main role is to maintain its commitment to outsourcing and handling high-quality products and delivering them to customers at a good value.
Up to these days, many solar distributors have been operating and helping many solar companies in distributing their products. So, if you are looking for the most trusted and reliable solar distributor, you can easily find one by checking out solar outsourcing companies that provide easy access to reliable information, news, data and a list of solar suppliers and distributors near you.
A summary of Sint Maarten’s solar markets
In 2014, Sint Maarten’s council of ministers sanctioned the National energy policy document. This document was supposed to usher in a new era of renewable energy in the Caribbean Island country. More specifically, the policy document envisioned an 80% renewable energy capacity by 2020. Unfortunately, none of the targets outlined in the document have been achieved.
According to an Energy Transitions Initiative (ETI) report released in 2021, Sint Maarten is 100% dependent on fossil fuels. This is pretty heartbreaking, considering that solar energy exploitation has taken the world by storm. However, the report notes that several private initiatives to exploit the Island’s solar energy potential have been observed recently.
Most leading hotels and resorts in Sint Maarten are increasingly adopting solar for their daily energy needs. Such private initiatives present enormous opportunities for solar installers and other photovoltaic professionals in Sint Maarten. You can land one or more of the personal solar projects sprouting up on the Island with a bit of determination.
Solar equipment supply capacity in Sint Maarten
There are several local and overseas suppliers of solar equipment serving Sint Maarten. Most local manufacturers cannot supply equipment for large-scale projects. Nevertheless, there is no need for concern because Solarfeeds has got you covered. If you go through our website, you will see an extensive list of solar equipment suppliers.
