Why battery backup
Pennsylvania outages aren’t rare — they’re expected
Tree-heavy neighborhoods, storm activity, and aging grid infrastructure make outages a regular part of life in Pennsylvania. A solar battery backup system can keep your home powered automatically — without fuel runs, noise, or fumes.
⚡
Automatic backup
Fast switchover keeps key circuits running when utility power drops.
🔋
Quiet + clean
No gasoline, no exhaust, no maintenance headaches like a portable generator.
☀️
Solar + storage
During daylight, solar can recharge the battery even while the grid is down (equipment dependent).
Already have solar?
Add battery backup to your existing solar system
If you already have solar, adding battery backup is often easier than you think. We review your inverter type, panel capacity, and wiring layout to recommend a clean retrofit path.
-
Retrofit-friendly options for many modern grid-tied systems
-
Critical-loads subpanel or whole-home configurations
-
Designed to meet current code and utility interconnection requirements

Battery backup makes sense if you…
Battery systems are not one-size-fits-all. We size around your loads, your outage risk, and your goals — not hype.
🌲
Live in a tree-heavy area
Wind and ice take down lines. Batteries keep the basics alive during long restoration windows.
💻
Work from home
Keep internet, outlets, lighting, and routers powered — automatically.
❄️
Need winter reliability
Support furnace blowers, pumps, and refrigeration through overnight outages.
How it works
What happens when the grid goes down
A proper battery backup setup includes controls that safely isolate your home from the grid during an outage, then restore normal operation when utility power returns.
🛡️
Grid isolation
The system disconnects from the grid to protect utility workers (anti-islanding).
🔁
Automatic switchover
Backup power takes over based on your chosen circuits and capacity.
📈
Load-aware design
We size around what you want to run — not marketing numbers.
TWO COMMON APPROACHES
Critical Loads
-
Lower cost, high impact
-
Fridge, lights, outlets, internet
-
Great first step
Whole Home
-
More capacity + integration
-
More circuits (HVAC optional)
-
Best comfort during long outages
*Whole-home capability depends on loads, panel configuration, and equipment selection. We’ll show the tradeoffs clearly.
FAQ
Battery backup in Pennsylvania: quick answers
These are the questions we hear most from PA homeowners considering solar battery backup.
Will a battery run my whole house? It can, but “whole home” depends on your loads (HVAC, well pumps, electric ranges) and the battery + inverter capacity. Many homeowners start with critical loads and expand later.
Do I need solar to add a battery? Not always. Batteries can be installed for backup alone, but solar + storage provides the best resilience by recharging during daylight (equipment dependent).
Can you add battery backup to an existing solar system? Often yes. We evaluate your inverter type, panel capacity, and wiring layout to determine the best retrofit approach.
How long will a battery last during an outage? Runtime depends on your battery size and what you power. A critical-loads setup can run essentials for many hours, and longer when solar can recharge during the day.
Is battery backup better than a generator? Batteries are quiet and automatic with no fuel, while generators can run longer if you keep fuel available. Many homeowners choose batteries for everyday reliability and convenience.
