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 Wholesalers
Wholesaling refers to buying some products or goods directly from its manufacturer usually at a discount and then reselling it to the retailers for a comparatively higher cost than the original. Basically, wholesalers handle products and package them in small quantities and then sell them to retail customers, either for commercial or personal use.
Many industries have wholesalers, and that will not skip the solar industries. Nowadays, many solar wholesale stores/firms are operating across the globe, making it much easier for retailers to go solar. Sometimes retailers find it hard to reach direct manufacturers of solar products because some companies do not have their solar stores/shops in public, with that they are not also offering solar products per piece. Through wholesale solar stores/shops, these individuals can easily buy the solar products that they need to replace or maintain their solar systems.
If you are in need of solar product suppliers for an individual purpose, you may visit some solar outsourcing marketplace to get an updated list of solar wholesalers near your location. There are many solar platforms that provide enough information and data about the solar industry in your region, including all the reliable solar wholesalers in town.
Solar Market Outlook in Nigeria
With a population of 200 million and an economy that relies mostly on its oil reserves, the economy of Nigeria is highly volatile. Add to that Nigeria’s electricity woes. Many residents and business owners in the country rely on generators to power up their business and even then a huge percentage of the population has no access to electricity.
Experts agree that this shouldn’t be the case as this is a tropical country. Geographically, its location close to the equator means that it has mostly sunny days throughout the year. The government is hoping that this renewable energy source could be the solution they’re seeking to combat the electricity woes that have haunted them for decades.
The National Renewable Energy and Energy Efficiency Policy in Nigeria was established in 2014. This policy details that Nigeria has a target of 20% electricity generation from renewable sources, mostly solar, in an effort to address the nationwide electricity shortage. They are also hoping to encourage more private investments in solar power plants.
There is notably a high solar potential in Nigeria, which gets up to 7 hours of sunlight daily. If this sunlight can be harnessed, it will produce 333,000 MW of solar power, which should be more than enough to bridge the electricity gap in the country.
Solar Energy Equipment Supply Capacity in Nigeria
Just as solar power plant projects are limited, there is also limited availability in local manufacturers of solar equipment in Nigeria. For those looking to make solar installations, you can turn to online or global suppliers and distributors for that.
Top Major Seaports & Logistics in Nigeria
Transporting and logistics handling of solar equipment into Nigeria should be easy since there are plenty of commercial ports available such as
- Lagos Port Complex,
- Calabar Port Complex,
- Delta Port,
- Rivers Port Complex,
- Tin Can Island Port,
- the Onne Port.
