General buying guidance only. It is not an engineering design, compliance determination or product specification.
Start with the reason for storage
Write down what the site is trying to change: demand peaks, backup for selected loads, solar self-consumption, generator use or another operating constraint. One project may have several goals, but the order matters.
Share measured data where possible
A single monthly bill is a starting clue, not a load profile. If the project team can provide interval data, note the date range, interval length, meter location and whether it covers a typical operating period.
- Electricity bills and tariff schedule
- 15-minute or 30-minute interval demand data, if available
- Operating hours, shutdown periods and seasonal changes
Describe the physical site
A layout, single-line diagram or a few clearly labelled photos can reveal access, equipment location and connection points. Mark what is confirmed and what is still being checked.
Keep roles and unknowns visible
Name the site owner, EPC, electrical contractor and decision-maker if known. Do not fill gaps with guesses; an explicit “not confirmed” is more useful than a false precision.
