A complete power decision, nota calculator with a login.
Sizr covers the whole path from an intake question to a priced, carbon modelled package your client will accept.
Sizing intelligence
The questions an engineer would ask,in the order they matter.
Intake is a conversation, not a form. Sizr asks only what changes the answer, then applies the same load logic every time so two people sizing the same site land on the same set.
- 01
AI guided intake
The assistant asks only what changes the answer, and explains why it is asking.
- 02
Load modelling
Diversity, duty cycles, heating, charging peaks and motor inrush applied consistently.
- 03
Hybrid battery pairing
Quiet hours modelled over the real programme, with the battery sized to shape the load.
- 04
Cabling and distribution
Powerlock, C form and lug tails specified with the set so nothing is missing on delivery.
- 05
Adjust and re run
Change a cabin count or a quiet hour and the whole package resizes in front of you.
Intake / equipment
