Wattonomy Pro turns your off-grid, marine or van design into a client-ready proposal in minutes — your logo, a clean wiring diagram, a sized parts list, e-sign and a deposit request. Stop losing evenings to spreadsheets and hand-drawn diagrams.
Size the bank on a spreadsheet, draw the wiring by hand, paste it into a Word doc, second-guess the fuse, chase the client for a signature. Hours per quote — and it still looks homemade.
Enter the loads, get a validated design, and export a branded proposal with the wiring diagram, sized parts list and build pack — e-sign and deposit included. Minutes, and it looks like a firm built it.
Pro is $29/mo for the Installer plan. Put in your own numbers:
Estimates only — hours-saved assumes Wattonomy gets you to a client-ready proposal in about 15 minutes. Your numbers will vary.
Your logo, pricing and markup on a clean, professional document. Proposal software lifts close rates because it looks credible and is easy to say yes to.
Every cable, fuse and AIC sized to ABYC E-11, ISO 13297, BS 7671 or AS/NZS — numbers that hold up to a surveyor, inspector or insurer.
e-sign, accept and a deposit request built into every quote — turn a yes into a booked, deposited job on the spot.
Off-grid, marine, van and RV DC systems — batteries, inverters, DC-DC, 12/24/48V — not grid-tied rooftop PV bolted on.
Full deliverables on every Pro tier — you climb on seats and team workflow, not on what you can hand a client. Unlimited branded proposals throughout.
Everything you need to design and quote your own jobs.
Everything in Installer, plus a team and a pipeline.
Everything in Studio, plus unlimited seats and dealer controls.

Most solar tools design grid-tied rooftop systems. Wattonomy is built for off-grid, marine, van/RV and small DC solar systems — battery banks, inverters, DC-DC, fusing and wiring sized to ABYC E-11 / ISO 13297 / BS 7671 — and it turns that design into a branded client proposal.
