The deformation of the battery is not sudden, it is often a process. The battery enters the high-voltage charging zone when it is charged to about 80% of its capacity. At this time, oxygen is first precipitated at the positive electrode, and the central enterprise reaches the negative electrode through the holes in the separator, and the oxygen resurrection reaction is carried out on the negative plate.

Solar water heaters are a way to reverse electricity trends and rising and falling bills. Solar water heaters are a way to reduce electricity consumption every day. It uses solar energy to heat water for various applications. You can use it for bathing, washing, cleaning, etc. The heater is usually

Gel battery is an improvement of ordinary lead-acid battery with liquid electrolyte. It replaces sulfuric acid electrolyte with colloidal electrolyte, which is better than ordinary batteries in terms of safety, storage capacity, discharge performance and service life.

Since the compact pressureless solar water heater uses an open pressureless water tank, the hot water outlet pressure is affected by the installation height of the solar water heater's water tank. If you install a non-pressure solar water heater, then you can get pressurized hot water through the following methods, and get a better comfortable experience when taking a bath.

The solar attic fan is just one of the fans that can help you provide proper ventilation in the attic area.Today, energy efficiency is a major concern for many manufacturers, and homeowners and energy-saving technologies are not only developing in the new energy sector, but also in reducing energy c

There is no denying that fresh air is vital to humans - we need it to survive. In an ideal world, we breathe clean, pure air all day long. Unfortunately, this is not the case. We are often exposed to poor indoor ventilation, which can be harmful to our health. There must be a well ventilated room at

This is a preheating solar water heater with a design of adding a copper coil to the water tank on the basis of the compact non-pressurized solar water heater.

During the long and hot summer days, solar water heating systems generate a lot of heat. At the same time, the demand for hot water is often at its lowest point. The combination of these two factors is a condition commonly referred to as "stagnation."Basically, when the solar water storage tank is h

Solar attic fans can also make the temperature of your home more comfortable overall and help prevent moisture and mould build-up in the attic, which can lead to wood deterioration and health problems.In the heat and sticky humidity, residents often escape inside their homes to enjoy the comfort of

Solar collector is a device that converts the radiant energy of the sun into heat. Because solar energy is relatively scattered, it is necessary to find a way to concentrate it, so the collector is a key part of various solar energy devices.

Solar hot water is a clean, reliable and cost-effective technology that can reduce utility bills for thousands of homes and businesses.Solar water heating is included in the term 'solar heating and cooling technology' along with solar pool heating, solar space heating, solar cooling and solar pre-he

Solar attic fans increase the comfort of your homeBy exhausting stuffy air from the attic and improving ventilation, solar attic fans can lower the temperature in your attic. Regulating the temperature in the attic helps rooms on lower floors and occupants of your home feel cooler and more comfortab

Domestic solar water heaters are generally based on integrated types. Whether it is a vacuum tube or flat plate solar water heater, the following aspects need to be considered for the installation location.

The general solar floor heating system is mainly composed of seven parts: solar collector, hot water storage tank, auxiliary heating device, pipe fittings, heat dissipation device, circulating pump and control system.

[Abstract] Most of us might take the hot water from the tap for granted. However, if you don't think about it, if your hot water system fails, you will miss the opportunity to provide hot water on demand. In households with electric water heating systems, we paid a considerable price for this privil

​The watering time of solar water heaters is best to choose to water under the condition of non-high temperature air exposure. The best time is two hours before sunrise or two hours after sunset.

When planning a roof replacement, it is important to consider ventilation. Professional roofing contractors understand the functions and benefits of having a well-ventilated loft and roof. The question is, how do you know which type of loft fan is right for your home?SUNFLOWER recommends the use of

A solar power fan is essentially a traditional loft fan connected to a solar panel instead of the home grid. Attic fans are important for sucking in cold air upward from the attic space and releasing hot air to the outside.Generally, the attic fan is installed on the roof of the house to form a flow

Professionally installed loft fans have many advantages. They reduce cooling costs and increase the efficiency of the HVAC system-the less heat in the attic, the less heat in the house. This means that the HVAC system has less work, which can save you energy and money. The insulation in the attic al

Nowadays, more and more people are installing solar water heating systems. Today, we will introduce several vacuum tube solar collectors commonly used in solar water heating systems. How is your evacuated tube solar collector for solar water heating system composed?The evacuated tube solar collect
