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 Slovakia
The Slovakian Energy Ministry is committed to pushing its renewable energy sector in order to achieve its target in the next 5 years or so. Majority of the solar energy sector is dependent on supply equipment from the US and other global developers of PV systems in order to meet its targets.
The current electric generation in Slovakia is lower than most other European countries. The Ministry of Energy wants to change that by opening up tenders for renewable auctions, citing that solar projects will have the largest share. The new clean energy scheme in the country wants to promote higher efficiency energy sources and the planned auctions will help them achieve that through more solar power projects.
The solar PV installations in Slovakia are mostly attributed to the residential installations with 472 MW of installed solar PV capacity as of 2019. The government is seeing a huge potential for solar energy generation in the country and it is reflected in the growing demand in supply for solar panels for roof installations. The potential for solar energy is estimated at 5,200 GWh per year.
Solar Energy Equipment Supply Capacity in Slovakia
Majority of the solar power equipment suppliers and distributors in Slovakia are from foreign investors such as those from the US, Germany, France, and Italy.
Top 8 Major Seaports & Logistics in Slovakia
To facilitate the logistics and transport of solar power equipment in Slovakia, the country has two major ports in operation today:
- the Port of Bratislava
- the Port of Komarno.
