Grid quality electrical power is a maze of transmission cables and transformers, generators and a host of electrical and electronic equipment. Understanding that generating electrical power in either 50 or 60 hertz for grid quality electrical power to customers worldwide, means a monthly billing for each one. This attachment to electrical power source has many switching capabilities for Net Zero, Net Metering capabilities for residential, commercial, industrial customers worldwide.
With the advancement in grid quality pure sinewave inverters grid quality electrical power can be matched to any grid tied electrical billing usage. These smart microprocessor controlled inverters can pick and choose which source of electrical power to operate the required wattage being operated. With electrical power transfers that are so fast between different sources that computer or clock resets are not necessary. There are many grid quality vendors on today's market that offer off the shelf products that can be mixed and matched to any wattage requirements.
By taking DC battery banking float voltage and storing this DC voltage than can produce massive amounts of electrical power in many different AC voltage ranges from KW, KV, MW options. What this means for electrical utilities customers is that they can size battery banks to their required needs and tell the electric meter to stay off for days or weeks at a time by this storage method until battery charging may be required.
