SAN DIEGO, Aug. 19, 2019 – On August 14, NeoVolta successfully connected its NV14 energy storage system (ESS) to an existing AC string inverter solar system. The homeowner wanted to replace their 10-year-old string inverter and install more solar panels. The result was installation of a new AC micro-inverter solar system, conversion of the existing system to DC, and installation of an NV14. The homeowner now has plenty of solar power and a highly capable and efficient ESS.
For this AC and DC solar installation, both AC and DC solar systems awake with sunrise and begin powering the critical loads first. Once those critical loads are fully powered, the excess solar recharges the NV14 battery system. Once the battery system is fully recharged, excess solar production is sent to the main service panel to power those loads, transferred back to the utility as Net Metering credits, or both. This setup maximizes both home loads and battery charge simultaneously. This helps to ensure that the battery is fully charged sooner, which decreases grid outage risk. It also minimizes the amount of inverting, improving overall efficiency. When the sun sets, the NV14 battery system powers the critical loads until sunrise the next morning. In the event of grid outage, the critical loads are powered by the battery system and the solar system.
NeoVolta designed its NV14 home energy storage system to help homeowners fight back against the utility companies. Energy generated during the daytime can be stored in the NV14’s clean, cobalt-free battery and used during evening “peak demand” hours when utility rates are often twice as high. The system’s inverter can be coupled to a DC panel for greater efficiency and additional savings. And in the event of a blackout, the NV14 will power a home’s critical loads indefinitely.
“Our NV14 is capable of connection with any residential solar system. In the past, solar systems had to include an inverter to convert the DC solar power to AC. The NV14 includes a highly capable inverter with our battery, so customers can save by installing the NV14 with DC solar panels,” said Brent Willson, CEO of NeoVolta. “The NV14 is an ideal retrofit for existing solar customers who are concerned about SDG&E’s Time-of-Use rates and grid outages. New solar customers can also benefit by not having to install inverters with a new solar installation.”
