Does Battery Not Ready mean I have no backup?

Yes, until the battery starts normally it cannot store solar or back up your home.

Not necessarily. Generac's listed causes include switches, cables and fuses, which a technician can check before replacing parts.

Common causes

The battery disconnect switch is off.
Zero stack voltage from an incomplete series connection between modules.
Battery communication cables out of sequence or not fully connected.
One or more battery fuses are blown.

Safe steps to try

Check the status light An orange light strobing every 2 seconds means Waiting. Solid orange means the battery is disabled.
Ask whether the disconnect was turned off Generac's first check is whether the battery disconnect switch is off. If someone serviced the system recently, ask them whether it was left off. Have your installer confirm before changing it.
Do not open the cabinet The other causes involve modules, cables and fuses inside the battery, which Generac says only a qualified technician should access.

When to call a professional

Contact your installer or a Generac Independent Authorized Service Dealer (IASD) if the battery stays in Waiting or Battery Not Ready. This is especially likely after a module replacement or other service.
