A new report by GOGLA shows annual sales of solar energy kits (lanterns, multi-light systems, and solar home systems) globally reached 9.5 million units in 2022, with 5.2 million sold between July and December 2022.

As distributed photovoltaics become increasingly prevalent in thousands of households, the demands for photovoltaic solutions are becoming more diverse. The conventional on- grid system, where photovoltaic power generation is primarily for self-use, is no longer the sole option. Depending on the specific requirements of different scenarios, photovoltaic power generation systems can be categorized into five types: photovoltaic on-grid systems, photovoltaic on-grid energy storage systems, photovoltaic off-grid energy storage systems, photovoltaic on/off-grid energy storage systems, and photovoltaic storage microgrid systems.

The new single-phase off-grid inverters have an AC output power ranging from 3.6 kW to 6 kW, Deye reports. The systems feature a maximum efficiency of 97.6% and a European efficiency rate of 96.5%.

Li-Air battery is a large-capacity lithium-ion battery jointly developed by the Japanese Technologies Institute (Japanese Technologies Institute, referred to as "Li-Air") and "Li-Air" (Japanese of Japanese, referred to as JSPS). The cathode of the battery is lithium metal, and the anode is oxygen in the air. The two electrodes are separated by a solid electrolyte; the electrode uses an organic electrolyte, and the electrode uses a water-based electrolyte.

The so-called overcharging, as the name suggests, means overcharging, that is, continuing to charge the battery after it is fully charged.
