What to check first
- Define backup duration or load-shifting needs
- Compare usable capacity, power and degradation terms
- Include installation, safety and replacement responsibilities
Define what the battery is expected to do
Backup support and energy shifting are different objectives. Identify the loads, required duration and operating pattern before comparing products. Separate usable energy capacity from the power that can be delivered at a given time.
Ask about degradation assumptions, operating conditions and end-of-life responsibilities. Include installation, controls and maintenance in the commercial comparison. Safety, location and protection requirements need qualified assessment for the actual site.
