Each of these controllers has its own functions and characteristics. In practice, due to different applications, we must be clear about the content of the controller applied to the application. The following are three mainstream types of solar charge controllers. The operating parameter settings of traditional solar charge controllers remain unchanged. Based on the parameter mode (constant voltage or constant current), the energy of the solar panel is transferred to the battery, and it will not change with changes in the surrounding environment.
PWM solar charge controller is also the most common, most cost-effective and easiest to deploy solar charge controller technology. Often referred to as a DC-to-DC converter by mistake, this controller is actually a switch similar to a switching power supply that matches the source voltage to the load voltage. Always ensure that the inverter battery is placed in an open or ventilated place, which can provide natural cooling air circulation to solve the problem of inverter battery heating.
Do not use, store or place the inverter battery in a hot place (for example, near a fire, near a heater, or a place exposed to direct sunlight). 4-wire terminal, generally the solar panel, battery, and load share the positive pole. You only need to connect it Connect the three positive poles together, and connect the negative pole as usual. Customers can refer to the load calculator on the Powmr website to select the best high-capacity inverter, and choose from a variety of inverter products designed for your home, office, showroom or gasoline pump.
It checks the work or function of standard photovoltaic regulators. It tracks battery charging while providing them with safety from under-charging or over-charging. If you connect the voltage stabilizer directly to the battery and then to the solar module, a high-quality MPPT solar charge controller will calculate and analyze the voltage at which the module can generate the maximum power for its capacity. The pure sine wave AC output is clean and distortion-free. When your equipment and electrical appliances only need pure sine wave current, using an improved sine wave power inverter may cause harm.
Therefore, although it looks expensive, a pure sine wave inverter can save you a lot. “Easy to heat” appliances such as microwave ovens and motors keep cool on pure sine wave inverters. And you need to know all the details of the photovoltaic system, such as input and output power, maximum battery current, nominal system voltage (12V, 24V, 36V, 48V, 60V, 100V, 150V, and even 200V). When considering which mppt controller to choose, please refer to the above mppt controller calculation guide. In order to remove these obstacles, UPS appeared.
What is UPS (uninterruptible power supply)? A UPS is a device, such as an inverter, that provides energy to the load in the event of a power failure. The low-capacity UPS with a capacity of up to 1.5KVA has a built-in battery of about 5Ah to 10Ah, which can provide 15-30 minutes of backup power in the event of a power failure. High-capacity systems are equipped with batteries outside the UPS, but the function depends on the UPS type. In addition, Powmr’s batteries are bundled in an attractive package to suit any home style layout. Powerful batteries provide backup power during power outages, and there is almost no need for emergency generators.
These household UPSs are good at running every household machine, including TVs, refrigerators, ventilation and cooling systems, etc. Basic knowledge of Solar Charge Controller. The solar charge controller is mainly designed for two basic matters in the solar power system: when there is no sunlight, stop the power from the battery through the solar panel, and optimize the solar panel to the battery cycle Charge. MPPT stands for Maximum Power Point Tracking is a technology that tracks and regulates the output energy from solar panels to batteries.
MPPT detects the output voltage and current of the solar panel in real time, continuously tracks the maximum power (P=U*I), and adjusts the output voltage accordingly, so that the system always charges the battery with the maximum power. We also have a series of high-quality inverters that can provide real-time data communication in terms of backup, inverter load percentage, battery charge percentage, etc. with the help of the built-in LCD display. The Zelio Plus series belongs to the high-quality inverter series. Overcharge safety, deep discharge safety, reverse polarity protection on the module side and battery side. Reverse polarity safety, short circuit safety and overvoltage safety at the module input from the internal fuse. In addition, you need to ensure that there is no battery open circuit safety, over temperature and overload safety, and even battery overvoltage shutdown.
