Portable solar generator is a safe, portable, efficient and environmentally friendly small energy storage system that provides you with a portable and sustainable green energy solution. Pay attention to the following aspects when using and maintaining:Portable UPS is a safe, portable, efficient and environmentally friendly small energy storage system that provides you with a portable and sustainable green energy solution. Pay attention to the following aspects when using and maintaining:

1, the first charge must have skills
After purchasing a new portable UPS, the UPS should be plugged into a 220V power supply and charged for at least 12 hours to ensure that the battery is fully charged. If the UPS is not used for a long time. It should be turned on for 24 hours every 2 to 3 months to fully charge it, and let the UPS power supply be in the inverter for 2 to 3 minutes to ensure the normal life of the battery. When the UPS is turned on, the battery pack will be charged. Press and hold the power button for more than 1 second to turn on the inverter.

2, reasonable choice of installation location
A good installation location is very important. The place where the portable UPS is placed must be well ventilated. Keep away from water, flammable gases and corrosive substances. The ambient temperature should be between 0 and 40 °C. Keep the air inlet and air outlet open.

3. Install a portable solar generator
Pay special attention to the order of the zero line (N), the fire line (L) and the ground line (G), pay special attention to the ground line. When the system ground fault occurs, do not connect the ground wire to the portable UPS.

4, pay attention to the safe operation of the operator
Safety measures should also be taken when connecting the output power to a portable UPS. Since the output voltage and current of the portable UPS are relatively large, it is necessary to pay attention to safety when connecting the output power to prevent electric shock.

5. Power-on and power-off sequence when using a portable solar generator
The correct power-on shutdown sequence should be to first turn on the UPS to power it, then turn on various loads to avoid damage from transient current surges during startup to the portable UPS. In the order of shutdown, the load should be turned off before the UPS is turned off.

6, avoid using portable solar generator overload
When using a portable UPS, calculate the load size. In order to avoid overload or underload, overload will cause the UPS to be overloaded for a long time, shortening the service life of the portable UPS. If the load is too small, the portable solar generator operating circuit is in an abnormal state for a long time, which is also harmful to the UPS. A reasonable load should be controlled between 50% and 80%.

7, portable UPS can not be idle for a long time
For portable UPS power supplies that have not been used for a long time, charge the UPS power supply to the charging circuit in the machine for 12 hours before restarting the power supply. For standby portable solar generator , it is best to run the portable UPS in reverse every other month. The transformer is operated for 2 to 3 minutes to activate the battery.

8, operation and maintenance
Strictly follow the corresponding power operating procedures during operation. In daily use, all power outlets on the UPS load side should be strictly managed; it is best to distinguish them from the power outlets by color or other effective methods. Unused UPS outlets should be turned off or off. It is strictly forbidden to connect electrical equipment that is not related to the computer on the UPS socket, especially high-power tools.

Lithium-ion battery, commonly known as “lithium battery”, is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. It is the best integrated battery system at present. The negative electrode of the lithium ion battery is a carbon material. For example, the graphite positive electrode is a lithium-containing transition metal oxide such as LiMn 2 O 4 .

Advantages of lithium-ion batteries:

1. The working voltage is high. Lithium-ion batteries operate at 3.6V, which is three times the operating voltage of nickel-cadmium and nickel-metal hydride batteries.
It is higher than energy. The specific energy of lithium-ion batteries has reached 140Wh / kg, which is three times that of nickel-cadmium batteries and 1.5 times that of nickel-hydrogen batteries.
3. Long cycle life. At present, the lithium ion battery has a cycle life of more than 1000 times, and can reach tens of thousands of times at a low discharge depth, exceeding several other secondary batteries.
4. Self-discharge is small. The monthly self-discharge rate of lithium-ion batteries is only 6-8%, which is much lower than that of nickel-cadmium batteries (25-30%) and nickel-hydrogen batteries (30-40%).
5. There is no memory effect. It can be charged as needed without degrading battery performance.
6. No pollution to the environment. There is no harmful substance in the lithium-ion battery, which is a veritable “green battery”.

Lithium polymer batteries are a new generation of batteries that entered the market in 1999. A lithium polymer battery is essentially the same as a lithium ion battery except that the electrolyte is a solid polymer rather than a liquid electrolyte.
The polymer electrolyte material is a general film composed of a solution in which an oxide of a host polymer such as polyethylene is used as a non-movable solvent.

Advantages of lithium polymer batteries:

1. Can be made into any shape and relatively light. Because it does not contain heavy metals and has a plastic shell that prevents electrolyte leakage. 2. Good performance and safer. The solid electrolyte acts like a sealing gel and does not easily disintegrate naturally during charging.

The principle of solar backpack:The principle of solar backpack:
The solar panel absorbs solar energy and converts the solar energy into electrical energy, which is stored in the built-in battery, and charges or supplies various mobile phones or electronic products according to different interfaces, and is suitable for emergency use without electricity.
The solar backpack looks like an ordinary backpack in appearance, but the difference is that it has a solar panel in front of it. The solar panel absorbs solar energy and converts the solar energy into electrical charge while storing the absorbed charge in a power box. This power box is hidden inside the backpack and can be directly connected to the charger of the mobile phone, MP3, digital camera for charging.

Solar folding bag SD series:

In order to prevent people from experiencing the loss of electronic equipment during their travels, Sungzu Jingrui has developed the SD series of solar folding bags, which can be used to charge electronic devices such as mobile phones or tablets through its built-in 60W high-efficiency solar panels. The backpack stores the power it receives directly in the solar panels on top of it and then powers any connected devices.

The SD series power unit features a stylish urban design that is not only extremely durable, but also waterproof and shockproof. The main body of the backpack is made of a special polyester 600D material, which keeps the packaging intact and greatly extends the life of the solar energy. The internal is equipped with a voltage-proof protective cable box to stabilize the voltage and safe output, but the smartest part is its external solar panel, which can charge the backpack at any time in a sunny place. The Shangzu SD series solar folding backpack is basically a very convenient battery pack.

The most painful thing in the world is that the mobile phone lacks power in its hands. Presumably, this is also the embarrassment of many people. Therefore, increasing the mobile phone life time has always been a problem that manufacturers need to overcome. In real life, there is a time when the mobile phone has no power, so the mobile power supply such as the charging treasure has become the standard of many mobile phones, but if these mobile power supplies are not powered?

If you use SD2122-2 solar mobile power supply, there will be no such defects. It uses ABS+ electroplating material, the surface is sun-finished, wear-resistant anti-slip and anti-fingerprint, and the solar sub-board uses anti-slip skin link, which does not take up space and is convenient to carry. .

Its mission is to continuously supply power to mainstream electronic devices such as Apple, Samsung, OPPO, VIVO, Xiaomi, Huawei, etc., using high-quality new Li-ion batteries, large capacity, timely battery life, and want to play. Just play.

Of course, it also comes with imported monocrystalline silicon solar charging board, and put it on the outside to start charging automatically! And even if you meet a cloudy day, you can charge it, it is a standard for outdoor play.

In normal use, the battery generally has self-discharge phenomenon, so if it is not used for a long time, the energy will be lost, so regular charge and discharge are needed to prevent energy loss. Solar mobile power is defined as having the advantages of being portable and portable, and converting solar energy into electrical energy and storing it in a battery. The portable solar generator system consists of five parts: power input circuits such as main circuit, bypass, battery, AC/DC converter rectifier, DC/AC converter, inverter and bypass output switch circuit, and energy storage battery.

Professional testing (inspection and testing) personnel can determine the quality of the battery by measuring the open circuit voltage of the battery. Take a 12V battery as an example. If the open circuit voltage is higher than 12.5V, it means that the battery has more than 80% energy storage. If the open circuit voltage is lower than 12.5V, it should be charged immediately.

In addition, if the open circuit voltage is lower than 12V, it means that the battery storage energy is less than 20%, and the battery may not work properly.

In addition, since the maintenance-free battery uses an absorbing electrolyte system, no gas is generated during normal use, but if the user uses it improperly, the battery is overcharged to generate gas. Will increase, therefore, will open the pressure valve on the battery, in severe cases, the battery will rise, deform, leak or even rupture.

All of the above phenomena can be judged from the appearance. If you find this, you should replace the battery immediately.

In addition to the above, a discharge test (TestMeasure) was periodically performed, the battery voltage was measured, and the appearance of the battery was visually inspected for deformation or expansion and leakage. You should also check the battery’s battery +, – the electrode is oxidized regularly; the battery terminals are loose. In addition, the longer the battery is used, the more intensive the maintenance, UHOTOSHOP can be used without delay. The best use of the battery is between 0 °C and 40 °C, avoid direct sunlight and keep it clean and ventilated.

Finally, it should be reminded that the person responsible for battery maintenance should perform battery maintenance under the guidance of a professional engineer, or directly ask a professional engineer for battery maintenance to avoid electric shock.
