How Amperage works
Docs
In plain English: the rules behind the recommendations, the model behind the numbers, and the terms behind the jargon.
Recommendations
How the sizing matrix and scenario cards are picked.
The exact rules Amperage uses to pick its four recommended solar and battery systems from the sizing matrix: Energy Ideal, NPV Maximising, Grant Maximising and Self-Sufficiency Maximising.
How Amperage compares up to three battery options against a project’s Base battery: what can differ, what stays shared, how each option is sized, and how to reuse a comparison set.
How one comparison option adds an extra load or an export limit on top of its battery: the Additional Loads Library, the Adjustments box on Solar & Battery, what moves in the numbers, and what happens when a Library row changes.
Getting started
From a blank project to an exported proposal.
A start-to-finish walkthrough of building your first Amperage project: bill entry, consumption upload, solar and battery setup, recommendations, and the customer deck.
How to enter a customer bill in Amperage: reading or typing the bill, the Bill Card, checking and confirming a read, the Charges on the Bill ledger, time-of-use windows with Match Bill Timings, demand charges, Where the Money Goes, and the Network Tariff Review on Recommendation.
How Amperage projects leave the app: the Customer deck and the A4 PowerPoint, the Prepare and send review, the other exports in the ▾ menu, Edit Copy, and the Share with Customer web link.
What each section of the Amperage Library holds: hardware, consumption profiles, network and retail tariffs, battery comparison sets, additional loads, presentation slides, export templates and pricing templates.
The difference between Analysis and Proposal projects in Amperage: which stages each one has, which to start in, how to switch between them, and what carries over.
How the Amperage Pricing page works for each option: where the money goes, the cost sections, margin vs markup, the certificate cards, and the Across Options comparison.
How to read the Amperage Proposal page for each option: the band, the section rows, the checks before you send, the customer link and the A4 PowerPoint export.
Every file format the Amperage consumption upload accepts (vertical and horizontal CSV, Excel, raw NEM12), with working examples, the rules applied on upload, and a Claude prompt for converting messy interval exports.
How the modelling works
Weather data, production, batteries, and the financial model.
What sits behind every Amperage number: TMY weather matching, hourly solar production simulation, hourly battery dispatch simulation, and the lifetime financial model.
How Amperage charges for replacing a battery and inverter mid-life: default trigger years, where the controls live in Analysis and Proposal projects, how blanks auto-derive, and where the cost shows up in payback, NPV, the cashflow chart and the proposal export.
Incentives
STCs, LGCs, VEECs, PDRS and how they stack.
