A Review of the Best Mid-Range MPPT Solar Charge Controllers in 2021

MPPT solar charge controllers are popularly used for small-scale solar systems, not exceeding 2kW. These solar system accessories are usually pocket-friendly, and their voltage ranges between 100-150V, typically manufactured for solar systems with 12V or 24V batteries. However, you can use many of them on 48V batteries as well. This article will discuss some of the most commonly used solar charge controllers. You can find more solar charge controllers on ...

What Is a Solar Charge Controller?

A solar charge controller (also known as a regulator) is identical to a traditional battery charger. Its function is to manage the solar charging process to ensure that the battery is effectively filled or, more critically, not overloaded. While solar charge controllers come in a wide variety of budgets, supply voltage, and functionalities, there are two major types: PWM and MPPT solar charge controller units. PWM variants are less complicated, utilizing a switch between the solar plant system and the storage devices. We ...

What Is Going On With China’s Crazy Clean Energy Installation Figures?

After China announced their official 2020 report on their figures in solar and wind system installations, plenty of analysts cannot believe what they have witnessed. According to China’s National Energy Administration, or NEA, the additional capacity for renewable energy systems is in a whopping total of 120 Gigawatts, which is an unrealistic number. Given the circumstance in 2020 where China has been the epicenter of the COVID-19 outbreak, achieving numbers beyond what all expected is simply impossible to happen. The official predictions by International Energy Agency and other entities won’t even exceed 50 Gigawatts on either ...

Vestas Launches the Largest Turbines in the World as Big 3 Competition Ramps Us

The 3 largest wind turbine companies in the West, namely GE, Siemens Gamesa, and Vestas, have been in constant competition with one another over the supremacy for the wind energy sector’s 3 factors of revenue: offshore, onshore, and services. It only takes one technology strategically introduced in order to propel either company into the top spot. Siemens Gamesa has undergone a recent change in leadership in the offshore department. Their current priority is sticking to what the offshore unit is best at and replicating it in multiple areas. Acquiring the company Senvion is a power move that aims to close the gap of competition ...
