Battery Backup FAQs
Can I add battery backup to my existing solar system?+
In most cases, yes. We assess your current inverter, panels, and electrical system to determine the best retrofit approach. Some older systems may need an inverter upgrade, which we handle end-to-end.
Is battery backup better than a gas generator?+
For most homeowners, yes. Batteries are silent, require zero maintenance, produce no fumes, and recharge automatically with solar. Generators require fuel storage, regular maintenance, and manual operation — the last thing you want during a hurricane.
How is this different from a solar + battery system?+
If you already have solar panels, this is simply adding the battery component you are missing. If you do not have solar yet, we recommend our solar + battery package to get the complete system.
