MPPT vs PWM: Charge difference PWM charges the battery with a constant 3-stage charge (bulk, float, and sink), while MPPT is maximum power point tracking, which can be thought of as a multi-stage charge. The conversion efficiency of MPPT is 30% higher than that of PWM. inverter batteries produce lead sulfate, which is deposited on the […]

To determine if a battery is functioning properly, you should inspect its surface for any deposits of dirt. If you find dirt, try cleaning it with a dry cloth. This way, you will be able to keep your battery clean. You may find it useful to buy a small pure sine wave inverter for any “special […]

PWM solar charge controllers are also the most common, cost-effective and easiest to deploy solar charge controller technology. Often incorrectly referred to as a DC-to-DC converter, this controller is actually a switch similar to a switching power supply, matching the source voltage to the load voltage. Offline UPSs have switchover times ranging from 6ms to […]

What if you could check the status of your inverter directly from your phone and plan accordingly? While this seems possible, until recently, nothing on the market offered this convenience. Now Powmr brings you this convenience via Zelio WiFi charging voltage difference. When using MPPT solar controller to charge low voltage battery via high voltage solar […]

Self-adhesive nipple covers (or silicone pasties) are especially great to wear year-round because they’re lightweight and practically invisible. Breathable and sweatproof, these options are typically circular in shape, stretching beyond the nipple to cover the entire areola. (Some, like the ones from Fashion Forms, are scalloped to look like flowers.) Most brands offer nipple-covers in a […]

Solar charge controller connections.1. Most solar controllers are 6-wire terminals. This makes it easy to determine which wires to connect. There are 3 groups, each with 2 positive and negative mounting holes. Usually, the solar panel wire is the first set of wires, then the battery, and finally the load, with the positive terminal connected […]

At the same time, the inverter starts drawing current from the battery and then supplies it to the AC load. Since it remains off while drawing current from the AC line during normal operation, it is called offline UPS tubular vs. flat batteries: If space is limited, then flat batteries are a better choice because of […]

However, since UPS units cost more, it does not make sense to run them for hours on end without power. A better solution is to choose an inverter that can be used as a UPS and vice versa. All powmr inverters are equipped with ECO and UPS mode, which converts the inverter to an offline UPS […]

Another point to note is that the inverter works in reverse, converting AC power to DC current during utility power on, which helps charge the battery. Since the batteries are connected externally to the inverter, higher capacity batteries, typically between 100Ah and 200Ah, are used to provide 2 hours to 5 hours of backup power. In […]

Short tubular cells are significantly smaller than tall tubular cells, but larger in height. This inverter battery is more convenient to store and carry. MPPT charge controllers require a higher price than PWM types, but have a wider range of applications, and in larger solar projects, mppt controllers are the only option. MPPT charge controllers require […]

The battery is the backbone of the inverter. It is responsible for increasing the efficiency and lifetime of the inverter. Regular battery repairs and maintenance not only ensure optimal performance of your backup power system, but also the safety of your home. Just like any other household equipment, the inverter and its battery also require standard […]

The Maximum Power Point Tracking (MPPT) system is an electronic system that enables the photovoltaic panel to output more power by adjusting the working state of the electrical modules. The direct current generated by solar panels can be efficiently stored in batteries. It can meet the residential and industrial electricity consumption in remote areas and […]

MPPT charge controller refers to the “maximum power point tracking” solar charge controller, which is an upgraded version of the traditional solar panel charge controller. The MPPT solar charge controller detects the voltage and current of the solar panel in real time, and keeps track of the maximum power (P=U*I), so that the system always […]

There are string inverter, microinverters, mixers and power optimizers: each has advantages and disadvantages, so how do you sift through offers and claims and decide which is right for you? We’ll walk you through the types and brands so you can ask the right questions of the installer and get the best option for your home […]

A square wave inverter produces an output that switches between positive, negative and zero volts, while a sine wave inverter uses filtering to approximate a true sine wave, similar to a grid like electricity. Most household appliances are designed to work with sine waves, which makes sine wave inverters safer than square waves. Tubular cells are […]

Solar Panel Voltage. For solar panels, we need to pay attention to operating voltage and short circuit voltage. The working voltage is generally 18V, 36V and so on. If the working voltage is 18V, the short circuit voltage of the solar panel should be 22V, also if it is 36V, the short circuit voltage should […]

Check the operation or function of the standard PV regulator. It tracks battery charging while providing them with safety from under or overcharging. You connect the regulator directly to the battery and then to the solar module. A high quality MPPT solar charge controller calculates and analyzes the voltage at which the module can produce […]

Today, inverter have become a necessity in homes and offices due to their efficient power backup capabilities. Matching your power requirements to the inverter you have becomes critical not only to ensure smoother electrical operation, but also to protect your equipment from any fuses or short circuits. Choosing the right UPS and battery for your home […]

Just like any other home appliance, your UPS and its batteries require regular maintenance to function efficiently and last longer. While they don’t beautify your home like your steel-coated double-door refrigerator or shiny black microwave, they can certainly help you live comfortably during the toughest times during a power outage. Powmr offers an extensive portfolio […]
