The Importance of a Solar Charger

Solar Charge Controllers are vital components of any off-grid solar energy system. They help prevent overcharging and deep discharging of batteries, and they optimize the conversion of solar input to battery power.

There are two main types of solar charge controllers: pulse width modulation (PWM) and maximum power point tracking (MPPT). Choosing the right one for your installation requires careful analysis. A consultation with a knowledgeable solar technician is recommended.

Battery Charger

The battery charger is a vital part of your off-grid solar system. It regulates the amperage and voltage input from PV arrays (or other power generators) to batteries, electrical loads and a solar inverter. A good charge controller will help extend your solar power battery life and protect your appliances from damage.

Our ECO-WORTHY charge controllers are the industry standard and deploy either pulse width modulation or maximum power point tracking technology to correctly regulate your solar battery charging system. Both technologies are highly effective in maximizing your solar energy system. We also offer more basic PWM charge controllers for those on a budget and/or who aren’t using high-voltage grid tie solar panels.

During the day, sunlight contacts your PV modules which convert solar energy into DC electrical power that runs your electric loads and charges your solar battery bank. Your solar battery system Solar Controller then uses its stored energy to run your appliances in the evening when there is no sun.

Most solar power kits utilize an intelligent battery charger with a built-in microprocessor to manage your system’s power flow. A basic charge controller will monitor and control your system’s voltage, current and temperature to ensure that your deep cycle solar battery does not get overcharged. More sophisticated battery controllers can even analyze the performance of your batteries to help you maximize your solar energy usage.


A power inverter is the brains of a solar-plus-battery storage system. It converts DC solar energy into standard AC electricity that can be used to run appliances. The inverter can also monitor the system and act as a portal for communication with computer networks.

An MPPT controller is often built into an all-in-one inverter that also acts as a battery charger and pure sine wave AC power inverter. These are perfect for off-grid applications such as remote cabins.

When an inverter is running, it can generate a lot of electrical power, which could overheat the transformer. It’s important to keep the inverter in a cool place and clean it regularly.

MPPT inverters are designed to optimize charging efficiency by matching the PV voltage with the battery, reducing charging current, and minimizing losses. MPPT inverters also provide a range of features such as LED system information displays and multiple electronic overcurrent protections.

The maximum amount of electricity that a PV system can produce is limited by the available battery capacity and the size of its AC loads. If the PV system’s AC PORTABLE POWER STATION loads exceed the battery capacity, there is a loss of power that cannot be recovered by the batteries. This loss is called “inverter clipping.” To avoid this, the inverter must be sized to accommodate the maximum DC power that will be produced by the PV system.

Charger Controller

Whether you’re going off-grid completely or simply adding a solar battery to your home system, you’ll need a charge controller to keep your batteries from overcharging. This is especially important if you are not connected to the grid, as excess power may be sent back into it.

A solar charge controller works by measuring the voltage of the battery and the solar panel array, and adjusting the amount of electricity that’s flowing into the battery. It will decrease the flow of electricity when the batteries are full to prevent overcharging, and increase it as the battery reaches a lower state of charge. The best solar charge controllers monitor the weather and adjust accordingly, ensuring that you’re always getting the most efficient charging possible.

Another function of the solar charge controller is to prevent current from flowing into the panels when it’s dark. Without this, the solar panels would produce too much voltage for the battery to process, and that can cause serious damage.

The most basic type of solar charge controller is called a PWM controller, and it uses simple shunt transistors to control the voltage in one or two steps (hence their names 1-stage and 2-stage controllers). They’re ideal for small DIY solar systems that feature relatively low-output panels and batteries. For larger solar-plus-storage systems, you’ll want to consider an MPPT charge controller instead.

LCD Display

LCD screens are used in laptops, tablets, smartphones, digital cameras and portable gaming devices. They are also found in industrial equipment and medical devices. LCDs do not produce light of their own, so they require external lighting to produce images on the screen. This light is called a backlight. It can be produced by LED (Light Emitting Diodes) or CCFL (Cold Cathode Fluorescent Lamps).

The screen is made up of millions of pixels that are arranged in a rectangular pattern on the panel. Each pixel has sub-pixels that can be switched off or on. When all the sub-pixels are off, the resulting image is black; when they are all on, it is white.

In an LCD display, there is a liquid crystal layer sandwiched between two polarizing filters, the axes of which are perpendicular to each other. When electricity is applied to the liquid crystal layer, the molecules untwist, which allows or blocks the flow of light through the LCD.

In order to provide an accurate color representation, a layer of a color filter is incorporated into the liquid crystal display. The color filter is fabricated through sputtering of chromium or indium tin oxide film. It is then deposited onto a glass substrate with a common electrode layer and shaped into vertical ridges by precision wetting processes.
