Grid-Interconnected Solar Energy System with Battery Storage
Per the National Electric Code, standard grid-interconnected solar systems have to shut down during a grid failure. This is to ensure that power will not back-feed to the grid and electrocute the utility line workers. However, if the installation has batteries, the inverter can “island” and be a self-sustaining system to power the home or business.
There are many advantages to having battery storage integrated into the solar system:
- The batteries provide backup power to run some or all of the electric loads in the home or business.
- The solar array continues to produce energy to power the home/business and charge the batteries even during a grid outage.
- The solar array can be oversized to provide power to both the inverter and charge the batteries.
- The batteries can deliver solar-generated electricity after sunset and on cloudy days.
- The batteries can be used to reduce Utility demand charges and time-of-use (TOU) rate plans.

Off-Grid Solar System
New Prairie can design a solar system that is completely off-grid for remote agricultural, cabin, or machinery applications. We analyze the load requirements and engineer a system of solar panels, inverters, charge controller, and batteries necessary to power the demand.
