Four operating modes of UPS

1、Normal operation mode

The principle of the power supply system is that when the utility power is normal, the machine will convert the alternating current of the utility power to direct current, and then charge the battery for use when the power is interrupted; it is emphasized here that the power supply system will not only act when the power is out, such as when the voltage is too low or high, or when there are instantaneous surges, etc., which are enough to affect the normal operation of the equipment and the quality of the power, the power supply system will be acted to provide stable and clean power for the equipment. When the utility power supply is normal, the utility power system will operate to provide equipment with stable and clean power. When the utility power is normally supplied, the utility power is filtered and divided into two circuits, one of which is charging the battery pack through the charging circuit, and the other is rectified as the input of the inverter, which is then converted to provide power for the loads to use; from this, it can be seen that the output of the on-line uninterruptible power supply system is supplied by the inverter, so that regardless of the quality of utility power, the output is stable and not affected in any way. Therefore, regardless of the quality of utility power, the output is stable and not affected in any way.

2、Battery operation mode
Once the utility power abnormalities occur, the DC power stored in the battery will be
converted to AC power, at this time the input of the inverter to be supplied by the battery pack, the inverter continues to provide power to supply the load to continue to use, to achieve the function of the uninterruptible power supply UPS uninterruptible power supply system source of power is the battery, and the capacity of the battery is limited, so the uninterruptible power supply system will not be like the utility power supply unlimited supply, so no matter how large the capacity of the uninterruptible power supply system under its full load state must be limited to the time of power supply. Therefore, no matter how large the capacity of the uninterruptible power supply system, in its fully loaded state, the power supply time must be limited, if you want to extend the discharge time, you must purchase a long time type of uninterruptible power supply system.

3、Bypass operation mode
When the on-line UPS is overloaded, bypass command (manual or automatic), overheating of the inverter or machine failure, the UPS generally turns the inverter output to bypass output, i.e., it is directly powered by the utility. Due to bypass, the UPS output frequency phase needs to be the same as the utility frequency phase, and therefore the use of phase-locked synchronization technology to ensure that the UPS output is synchronized with the utility. Bypass switch bi-directional thyristor parallel mode of operation, to solve the problem of bypass switching time, truly uninterrupted switching, control circuit is complex, generally used in medium and high power UPS. If the load must be artificially reduced in case of overload, otherwise the bypass circuit breaker will automatically cut off the output.

4, bypass maintenance mode when the UPS for maintenance, through the manual bypass to ensure the normal power supply of the load equipment, when the maintenance operation is completed, restart the UPS, UPS to normal operation. Extremely low maintenance rate, greatly improving the availability of UPS uninterruptible power supply.

How Many Solar Batteries Are Needed to Power a House?

Catl Energy Storage

As the integration of solar energy systems into residential properties becomes increasingly prevalent, many homeowners are exploring energy storage solutions to enhance the efficiency and reliability of their solar installations. Solar batteries are pivotal in this regard, enabling the storage of surplus energy generated during peak sunlight hours for later use. A key question often arises: "How many solar batteries are required to power a home effectively?"

Assessing Household Energy Consumption

The foundation of determining the necessary number of solar batteries lies in a comprehensive understanding of a household's energy consumption, typically measured in kilowatt-hours (kWh). The average U.S. household consumes approximately 877 kWh monthly, equating to about 29 kWh per day. However, energy usage varies significantly depending on factors such as the home's size, the number of occupants, and the prevalence of energy-intensive appliances.

To gain an accurate assessment of your energy requirements, it is advisable to review your electricity consumption over the past year. This historical data provides insights into your average daily and monthly energy usage, forming the basis for calculating your energy storage needs.

Understanding Battery Capacity and Efficiency

Solar batteries are characterized by their capacity, expressed in kilowatt-hours (kWh), which denotes the total energy they can store. For example, a commonly available residential battery may have a capacity of 10 kWh. However, the usable capacity of a battery is typically less than its total capacity due to the Depth of Discharge (DoD), which represents the percentage of the battery that can be discharged without degrading its performance or lifespan. A typical DoD for many batteries is around 90%, meaning a 10 kWh battery effectively provides 9 kWh of usable energy.

Calculating the Required Number of Batteries

To estimate the number of solar batteries necessary to meet your household's energy needs, consider both your daily energy consumption and the usable capacity of the batteries. The calculation can be simplified as follows:

Number of Batteries = (Daily Energy Consumption) / (Usable Battery Capacity)

For instance, if your household's daily energy consumption is 30 kWh and you are using batteries with a usable capacity of 9 kWh, you would require approximately 3.3 batteries to meet your daily energy needs. In practice, this figure would be rounded up to 4 batteries to ensure adequate energy storage, particularly during periods of reduced solar generation.

Considering Energy Autonomy and Reserve Capacity

When designing a solar battery system, it is also essential to consider the desired level of energy autonomy. For households seeking the capability to operate independently of the grid for extended periods—such as during power outages—the number of batteries required would increase accordingly. For example, to maintain autonomy for three days with a daily consumption of 30 kWh, a homeowner would require 12 batteries.

In addition, it is prudent to incorporate a reserve capacity to accommodate unexpected fluctuations in energy consumption or variations in solar energy production due to weather conditions.

Conclusion

The determination of the appropriate number of solar batteries to power a residence is contingent upon several factors, including daily energy consumption, battery capacity and efficiency, and the desired level of energy autonomy. By thoroughly evaluating these factors, homeowners can design a solar battery system that meets their specific needs, ensuring a reliable and sustainable energy supply.

About Portable Power Station

Portable Power Station (Portable energy storage outdoor power supply), core device lithium battery, first of all, fully consider the actual needs of indoor and outdoor in terms of volume, smaller size design, compared with traditional lead-acid batteries smaller and lighter, easy to use and carry. In terms of safety, energy saving and environmental protection, the traditional lead-acid battery is abandoned, no noise and no pollution, and has excellent safety performance.

At the same time, many characteristics such as high storage energy density, large capacity, stable performance, and long cycle life have become the crystallization of wisdom under the development of modern manufacturing industry. And under the high-quality life, it can better meet the small household appliances used in home life to boil water and cook, and can also be used for power supply needs of daily consumer electronic products.

Points to choose outdoor power supply

There are two main points to look at when purchasing an outdoor power supply: one is the capacity of the power supply (Wh watt-hour), and the other is the power supply (W watts). The capacity of the power supply determines the length of available power, the larger the capacity, the more power and the longer the use time. The power of the power supply determines the types of electrical appliances that can be used. For example, an outdoor power supply with a rated power of 1800W can drive electrical appliances below 1800W. At the same time, this formula (watt-hour ÷ power = available time of electrical appliances) can be used to calculate the available time of electrical appliances under different capacity power sources.

Outdoor Power Usage Scenarios

Now we have a certain understanding of the capacity and power of the power supply. Next, we can choose according to the number of users, electrical appliances, and usage scenarios. Scenarios for using outdoor power supplies can generally be divided into two types: leisure camping/self-driving travel, and their characteristics and requirements are summarized as follows:

Leisure camping:

1-2 days of camping: the camping scene is to invite three or five friends to go camping on weekends. Estimated electrical equipment: mobile phones, speakers, projectors, cameras, Switches, electric fans, etc. Keywords: short distance, leisure, entertainment. Because the camping time is short (two days and one night), the demand for electricity is not strong, and it only needs to meet part of the entertainment, so it is recommended to choose a small-capacity power supply.

Travel by car:

If you choose to travel by car, you don’t have to be too strict about the weight of the power supply, but you are more concerned about the capacity/power of the power supply. Compared with leisure camping, self-driving travel has more time and more usage scenarios, including: car refrigerators, rice cookers, electric blankets, kettles, computers, projectors, drones, cameras and other high-power electrical appliances.

Charging method:

At present, the mainstream charging methods include municipal electricity charging, car port charging and solar energy. In addition to the mains interface as a basic accessory, other charging methods may require the purchase of corresponding charging accessories. If you stay outdoors for a long time, it is still necessary to support the solar panel charging interface.ESUN also provide the optional solar panel for you to choose equip with the power station and charge anytime when you have a good solar condition.

Output Interface:

Usually necessary are USB-A, Type-C, and AC output and DC interface. USB-A port, supports mobile devices. Type-C supports PD fast charging protocol devices such as mobile phones and notebooks to improve the charging efficiency of mobile devices. The AC interface provides AC 220V voltage and supports most electronic equipment such as sockets. The DC interface can provide car charger power supply or other devices that support 12V power supply.

Volume and weight:

Outdoor power supplies are generally made of lithium batteries. Outdoor power station require higher power and larger capacity, requiring more lithium batteries to be combined in series, thereby increasing the volume and weight of outdoor power supplies. When choosing an outdoor mobile power station, you can choose an outdoor power supply product with the same capacity and smaller weight and volume.

Capacity Zhceenergy have:

300W/650W/1000W/2000W/3000W/5000W
