Important Notes:
- Runtime estimates are approximate and depend on appliance consumption, inverter efficiency, battery condition, and operating conditions.
- Refrigerators and freezers cycle on and off, so actual runtime may differ significantly.
- Multiple appliances running simultaneously will reduce backup time.
- Total connected AC loads should not exceed the system’s rated 1000W output.
- Appliances with high startup power requirements should be checked for compatibility before use.
