NABCEP Registered Provider Continuing Education

NABCEP Recertification Classes

Fortress Power offers continuing education classes on battery components and pain points.

These make excellent classes for those seeking better familiarity with lithium batteries systems.

Both classes are available for 1 continuing education credit for NABCEP PV Installers, Associates, Technical Sales, Design Specialists, Commissioning and Maintenance Experts, and System Inspectors.

Live student-instructor interaction is available both during our regularly scheduled live webinars and on-demand within the Discord classroom. On-demand classes will be available roughly ~1 week after our first live program.

Battery Sizing for Behind-The-Meter Applications


Battery applications are forcing installers to re-evaluate solar design to ensure system performance meets customer expectations. Learn techniques for right-sizing battery capacity for a variety of popular residential and commercial applications. Improve your project estimating capability to have better conversations with your solar customer ahead of the project and explore concepts which can improve system economics beyond net-metered solar arrays.


Sizing Tools (discussed throughout)

Off-grid Sizing

Residential Net-Metered

Residential Variable Rates

Residential Zero Outflow

Whole House Backup

Commercial Demand Management

Learning Objectives

Develop an energy model using monthly electric bills and spreadsheets to improve project estimating while better understanding the benefits of commercial modeling software.

Explore how grid policy impacts minimum battery sizes to provide reliable backup power to customers while maintaining or improving system economics.

Identify system material and programming necessary to implement “zero outflow” solar arrays while protecting critical load panels, as well as additional costs and reliability concerns with whole house offgrid, to better set customer expectations with energy security needs.

Review how commercial demand management can provide economic, battery backup to customers particularly for businesses which lack consumer-friendly solar policy, to increase the rate of renewable adoption.
