NeoVolta Inc. (OTCQB: NEOV) – NeoVolta Inc., manufacturer of Smart Energy Storage Solutions, has developed a patent-pending technology for converting a backup generator’s 240-volt Alternating Current (AC) power output to Direct Current (DC). This device gives NeoVolta customers an additional generator option, further extending the charge of the NV14 storage battery during a grid outage. The unit does not require any special modifications, making it a very simple and inexpensive option compared to the cost of “stacking” additional storage batteries.
The technology capitalizes on NeoVolta’s ability to integrate with any residential backup generator and its compatibility with either AC or DC solar panels. Because most customers have AC solar, the DC solar input would typically go unused. With this device, an AC generator can be connected to the DC solar input. The unit tested successfully under every condition used to evaluate it, and the patent filing was recorded by the U.S. Patent and Trademark Office on March 1, 2021.
“During an extended power outage, NeoVolta’s high-capacity storage system will last even longer by integrating backup generators,” said CEO Brent Willson, CEO of NeoVolta. “This power converter is a very promising breakthrough that gives our customers an additional source of protection.”
NeoVolta storage systems are designed for safety and performance. They use lithium iron phosphate battery chemistry, the nonflammable and nontoxic alternative to lithium ion. NeoVolta’s flagship NV14 energy storage system has a very high storage capacity of 14.4 kilowatt-hours, expandable to 24.0 kWh with the optional NV24 battery—without the expense of a second inverter. The system’s inverter discharges 7.7 kilowatts of instantaneous power, more than most mainstream competitors.
If I understand this right, we are basically converting AC from backup generator to DC to charge the batteries in the event of a grid outage. With the additional charge in the batteries, you could supply the load. Now, that’s adding more inefficiency since the batteries could work in AC-coupled mode with other sources like backup generator and / or PV to cater to the loads. Why waste another cycle of battery / incur the round-trip efficiency (or inefficiency) of the battery when we can direct power the load!
