Solar Backup During Load Shedding
What a backup system does the moment the grid disappears.
When the grid drops, a hybrid or backup inverter disconnects from the utility and continues to supply the circuits wired to its backup output. Solar production, where available, continues to feed those loads and to charge the battery.
Which circuits stay on is a design decision made during installation, not something the equipment decides. Essential-load designs keep lighting, plugs, connectivity and refrigeration alive. Full-home designs cover everything but require considerably more inverter and battery capacity.
Grid-tied systems without storage shut down during an outage by design. This is a safety requirement, and it is the single most common surprise for owners of older installations.
If your existing system goes dark during load shedding, an inspection will show whether a battery and hybrid inverter upgrade is viable on the equipment you already own.
