Help
Beginner concept guides and task-by-task help for the whole app — the designer, parts catalogue, costs and exports.
Learn the concepts
Plain-language primers on the decisions behind a solid off-grid system.
Sizing your battery bank
Work out how much battery capacity you actually need from your daily energy use and how many cloudy days you want to ride out.
Read →Choosing wire gauge & fuses
Pick conductor sizes that carry the current without overheating or sagging in voltage, and fuse every circuit to protect the wire.
Read →12V vs 24V vs 48V
Higher system voltage means lower current, thinner cables and easier wiring — but more components and a few trade-offs. Here is how to choose.
Read →Terminals, lugs & crimping
Which terminal to use where, how terminals are sized, and how to crimp connections that survive years of vibration in a vehicle or boat.

Use the app
Task-oriented help for every part of Off Grid Builder.
Getting started
What Off Grid Builder is, what is free, what costs money, and the two ways to begin: jump into the designer or take the guided setup.
Read →The designer: boards, components & the canvas
Working on the canvas: panning and zooming, drawing and reshaping boards, placing real-size components, rotating, locking, the properties panel and undo.
Read →Wiring & validation
Connecting terminals, shaping wire runs, setting gauge, fuses and lengths, and reading the calculations & validation panel.
Read →Saving & paying
How the free draft, sign-in and the one-time $19 per-installation unlock fit together, and what happens after checkout.
Read →Exporting your design
The export menu on an unlocked installation: PNG, 1:1 PDF, SVG, CAD-ready DXF and the wiring CSV — what each contains.
Read →The parts catalogue
Browsing real parts with real dimensions, reading a part page (specs, terminals, datasheets, buy links), and submitting a part of your own.
Read →Costs & the bill of materials
The Costs page: component, cable and connector line-items priced from your current draft, and the downloadable BOM CSV.
Read →The examples gallery
Browsing published example systems, cloning one into your own installation, and submitting your design as an example.
Read →Your dashboard & referrals
Managing saved installations (open, rename, delete, thumbnails), tracking example submissions, and sharing your referral link.
Read →Profile & settings
Your account: profile photo, display name, changing your password, theme, and logging out.
