The difference between home energy storage and outdoor portable power supply?

Outdoor portable power supply is generally built-in high energy density lithium-ion batteries, long cycle life, light weight and easy to carry, and its overall performance is more stable and reliable, but also easy to operate, low noise, good maintenance and other characteristics, to better meet the emergency power supply and outdoor operations with electricity needs. In addition, outdoor portable power it can reserve power, with multi-functional output interface, AC output, USB output, car charger interface output, convenient for users to use in different scenarios, more selective, more convenient to use.

1, a high-degree of integration: portable power station to decentralized charging devices, power storage devices, power supply devices highly integrated into one, convenient for users to use.

2, Convenience: Portable energy storage power supply, small size, light weight, from a few kilograms to dozens of kilograms, easy to load and unload, transportation, where the need to move, no need to disassemble, wiring, installation, easy to use.

3, Diversity of power storage function: portable camping electricity generator can store solar power, utility grid power, car power, generator power, wind power.

4, Power supply function diversity: the battery storage of electricity released, mainly to provide high-power AC power, supply our life appliances, such as refrigerators, air conditioners; auxiliary DC power, supply electronic products, such as cell phones, cameras.

5、Disadvantages: limited storage capacity, limited power, can not be unlimited use, must be planned for use, or supporting the use of power generation devices, expensive and can not be popularized.

Household energy storage power

Household energy storage system is based on the traditional photovoltaic grid-connected power generation system to increase the lithium battery storage power, by the battery, hybrid inverter, photovoltaic panels with the combination of a new type of energy acquisition, storage, use of hybrid systems. The following is an introduction to the common household PV + energy storage system types and features.

1. Hybrid home PV + energy storage system

Hybrid PV + energy storage system generally consists of PV modules, Li-ion battery, hybrid inverter, smart meter, CT, grid, grid-connected loads and off-grid loads. The system can realize PV charging the battery directly by DC-DC conversion, and can also realize bi-directional DC-AC conversion for battery charging and discharging.

2、Coupled home PV + energy storage system

Coupled PV + energy storage system, also known as AC retrofit PV + energy storage system, the system generally consists of PV modules, grid-connected inverter, lithium batteries, AC-coupled storage inverter, smart meter, CT, grid, grid-connected loads and off-grid loads. The system can realize that after the PV is converted to AC power by the grid-connected inverter, the excess power will be converted to DC power and stored in the battery by the AC-coupled energy storage inverter.

3、Off-the-grid type household PV+energy storage system

Off-grid home PV + energy storage system generally consists of PV modules, lithium batteries, off-grid energy storage inverters, loads and diesel generators. The system can realize PV charging directly to the battery by DC-DC conversion, and can also realize bidirectional DC-AC conversion for battery charging and discharging.

4、Photovoltaic energy storage energy management system

Photovoltaic energy storage energy management system, the system generally consists of photovoltaic modules, grid-connected inverters, lithium batteries, AC-coupled energy storage inverters, smart meters, CT, grid and control system. The control system can receive and respond to external commands, respond to the system's electricity demand, accept the system's real-time control and scheduling, and can participate in the optimal operation of the power grid, making the use of electricity more efficient and economical. The biggest significance of the emergence of portable energy storage power supply has changed our living habits.

No logistics power generation system is the most important significance of portable energy storage power supply.

Portable energy storage power supply + photovoltaic power generation combination, is a set of "no logistical power generation system", does not burn oil, does not burn coal, without logistical support, has a constant flow of electricity. Relying on photovoltaic power generation during the day, using electricity while generating electricity, storing the inexhaustible electricity, and using the stored electricity at night, week after week, allowing us to get rid of the "grid" bound. The future of portable energy storage power + photovoltaic power generation, fuel generators as a supplement to become our outdoor power priority options, this way of using electricity to greatly enhance our outdoor residual capacity.
