When designing your backup power system, one of the most important decisions is choosing between a critical load panel and a whole-home backup solution. With Sol-Ark’s flexible hybrid inverters, you’re not locked in a single path. You can build what fits your lifestyle today and expand as your needs grow.
What Is a Critical Load Panel?
A critical load panel, also known as an essential loads panel, powers only the most important circuits during an outage. This typically includes refrigeration, internet, lighting, and key outlets.
This approach is ideal for:
- Homeowners working within a specific budget
- Properties with smaller battery banks
- Long-duration outage strategies that prioritize power efficiency
Sol-Ark’s hybrid inverters simplify this setup with built-in smart load management and integrated breakers, no external add-ons or complex wiring needed.
What Is Whole-Home Backup?
Whole-home backup means everything stays on. From HVAC and kitchen appliances to EV chargers and water pumps, Sol-Ark inverters like the 15K and Limitless series can handle it all.
Key features that enable whole-home power:
- 200A grid passthrough; no need to rewire your main panel
- High power output and battery storage compatibility
- Seamless transition from grid to backup with zero downtime
If you want total comfort and performance, even during extended outages, this is the solution.
