We are no stranger to the full Netcom mobile phone. In our impression, it is the network standard that can support the three major operators in China. We don't need to know that it is a mobile version, China Unicom version or a telecom version, because it can support it. At the same time, its price is higher than other versions. However, in the era of 4G+, Qualcomm has a strong definition and a deep accumulation in the field of wireless connectivity.
There is a new interpretation of the definition of Netcom
Most of the Netcom that we are talking about now is passed down in the 3G era. In the era of 4G+, we must add new elements to the whole Netcom. Based on Qualcomm's interpretation, Nine Dragons Netcom contains five major aspects. It is also understood that all carrier network standards, ie, all 7 modes (LTE-FDD, TD-LTE, TD-SCDMA, WCDMA, EV-DO, CDMA1X, GSM) are supported. In addition, it also includes various dual-card dual-standby combinations that support “blind pluggingâ€, one SKU supports all carrier aggregation band combinations of Chinese operators, and supports full-mode voice, including 20 voice modes and LTE data and voice convergence.
For the now very common dual-card design, the new Full Netcom can also be solved very well. Users can choose to blindly insert any two 4GSIM cards of the three operators. We can choose any carrier's data master card at any time in the mobile phone system (of course, two telecom cards are still not allowed). In addition, in the 4G+ era, the Opteron processor can support all operators' 4G+ networks, while the uplink and downlink have faster performance.
The off-grid inverter is an inverter used in off-grid solar power generation systems. Its main function is to convert the direct current generated by solar panels into alternating current to meet the power demand in off-grid environments, such as in remote areas, In camping, boats, or moving vehicles.
Main effect:
Converts the direct current generated by solar panels into alternating current to supply the power needs of homes, mobile devices, or other electrical appliances.
Off-grid inverters are usually equipped with battery energy storage systems, which store excess power so that they can continue to supply power when the solar panels cannot generate enough power.
Differences from On-Grid Inverter:
Connection method: Off-grid inverter is an inverter used in the off-grid system and does not need to be connected to the grid. They are often used in places where there is no access to the grid, such as remote areas, wild camping, or outlying islands.
Grid requirements: Unlike on-grid inverters, off-grid inverters do not need to meet grid requirements and standards because they are not connected to the grid. They can operate independently and can be adapted to different off-grid environments.
Self-sufficiency: The off-grid inverter is equipped with a battery energy storage system, which can store excess electricity so that it can continue to supply electricity when the solar panels are unable to generate electricity. This makes the off-grid system self-sufficient and not dependent on an external grid for power.
Application scenarios: Off-grid inverters are widely used in remote areas, camping, ships, mobile vehicles, and some special-purpose scenarios. On the other hand, grid-connected inverters are mainly used in home, commercial, and industrial photovoltaic power generation systems connected to the grid.
In general, the main function of the off-grid inverter is to convert the direct current generated by the solar panels into alternating current to meet the power demand in the off-grid environment and achieve self-sufficiency by being equipped with a battery energy storage system. In contrast, on-grid inverters connected to the grid are mainly used to integrate solar power into the grid, realize the interaction between solar power and the grid, and comply with the requirements and standards of the grid.
