Residential: power around the real load.

Load profile to assess

• Fans, lights and Wi-Fi
• Refrigerator startup surge
• Requested backup duration

Planning checklist, not a measured Qwik installation. Final ratings follow a site assessment.

System direction

Pure sine-wave inverter with tubular or compatible lithium storage

Why the sizing changes

• Essential watts, not every connected appliance
• Ventilation and battery placement
• Recharge time between outages
