How to compare this quote

Compare quotes using the same backup scope, not just the battery brand or headline price.
Ask each installer to explain site assessment assumptions, protected loads, capacity, and estimated runtime.
Confirm whether solar can recharge the battery during an outage and what equipment is required.
Review financing, incentives, warranties, maintenance, and utility interconnection responsibilities.
Check contractor licensing and make sure the written proposal names the equipment and work covered.
