Battery System Sizing
I’m trying to determine if a 30kWh rack battery setup—specifically looking at the EG4 options—would be sufficient to
carry a 48-hour outage during a winter ice storm.
My Load Profile:
- Heating: Natural gas (minimal electrical draw for the blower).
- Critical Loads: Refrigerator, LED lighting, and essential home office electronics.
Specific Questions:
1. Has anyone in the local area tested their real-world runtime in freezing temperatures?
2. If the batteries are mounted in the garage, should I prioritize models with integrated heating or add external heating pads to prevent charging or is this even an issue?
