As Tesla’s Powerwall products meet new competitors, Sonnen has introduced its own home battery backup, which can provide users with reliable temporary power supply in case of grid failure. The sonnencore home battery, which can be integrated into a home’s solar power system for charging, will switch the house to battery power if the conventional power supply fails, whether due to an accident or a planned power failure. < / P > < p > this kind of switching is completed in about 0.4 seconds, which is so fast that most electrical appliances will not notice this change. The available capacity of the battery is 10 kwh, which can continuously output 4.8 kW power. Its peak output power is 8.6 kW to meet the large power demand of some electrical appliances and equipment at the initial start-up. < / P > < p > the LiFePO4 battery itself has a rated life of 10000 cycles, i.e. 10 years. Sonnen said it had a life expectancy throughput of 58 MWh and a discharge depth of 100%. Although home backup batteries, such as Powerwall and sonnencore, are usually associated with solar panel systems, they do not actually require energy from photovoltaic sources. < / P > < p > Sonnen said that the sonnencore home battery can be charged from the normal grid and used as a backup battery in case of power failure, and it can also be used for load transfer of service time. That is to say, users can use off peak, cheaper energy to charge it, and when grid power is more expensive, users can make sonnencore home batteries work to power home appliances. < / P > < p > sonnencore home batteries come with remote applications for control and monitoring, setting charging and peak times, and showing how much energy is being used and how much energy is being stored. In addition, it supports the combination of multiple sonnencore batteries to meet the needs of homes or other buildings with greater power demand. The sonnencore home battery costs $9500 per device, excluding installation costs. After 12 years, “world class Super project” Shantou Bay Tunnel ushers in a historic breakthrough today
