Off-grid failures usually start with fantasy load lists. MrSolar’s off-grid load calculator pushes Australian remote-home planners to total daily watt-hours before dreaming about panel counts. Bring the results to CEC-accredited off-grid specialists — autonomy days, battery usable kWh and generator strategy all hang off this spreadsheet. Treat suburban STC and battery program headlines as items to verify, not copy-paste budget fillers.

Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.
Free for homeowners. Participating installers pay MrSolar a lead fee when matched — that does not buy a higher ranking in our guides or reviews. See how we match quotes and is MrSolar legit?
Refrigeration, pumps, lighting, communications, tools and seasonal guests belong in the sheet. Phantom loads add up — measure where you can. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “List every load with hours/day”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “List every load with hours/day” using your app’s import/export charts — that feedback loop is how off-grid load calculator stays aligned with real tariffs and DNSP behaviour.
The calculator aggregates Wh/day so designers can size batteries in usable kWh and arrays for seasonal minima. Homeowners comparing Off-Grid Load Calculator — Build the kWh Spreadsheet Properly should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Convert watts to watt-hours”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
Mark what must survive autonomy days versus what can wait for sunshine or generator time. That split changes architecture cost dramatically. If two quotes disagree on “Separate critical vs deferrable loads”, ask both to show workings with as-of dates (STC spot and subsidy rules) rather than accepting a verbal reassurance. On the “Separate critical vs deferrable loads” point for off-grid load calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/off-grid-load-calculator.
Welders, bore pumps and compressors demand inverter and generator headroom beyond average kWh. Add peak watts commentary for your installer. Keep Epic Unicorn Pty Ltd / MrSolar matching separate from installer contracts: accreditation and incentive claims must appear on the installer’s paperwork for /solar-calculators/off-grid-load-calculator. Homeowners comparing Off-Grid Load Calculator — Build the kWh Spreadsheet Properly should treat vague wording as incomplete — especially around CEC accreditation and the Cheaper Home Batteries Program planning figure of ~$372/kWh usable where storage is involved.
Two cloudy days versus five is not a vibe check — it is a capital decision. Be honest about generator willingness. Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Autonomy targets drive battery kWh”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions. After install, revisit “Autonomy targets drive battery kWh” using your app’s import/export charts — that feedback loop is how off-grid load calculator stays aligned with real tariffs and DNSP behaviour.
Certificate eligibility can differ from grid-connect rooftop norms. Confirm STCs and any storage discounts in writing for your configuration.

Australian 2026 context still rewards self-consumption over FiT hunting; when reading “Incentives caveat for off-grid”, check whether the advice pushes daytime loads, EV charging, or storage instead of unlimited export assumptions.
MrSolar introduces off-grid capable CEC-accredited partners. Share calculator exports so quotes start from the same load truth. On the “Hand the sheet to matched installers” point for off-grid load calculator, write acceptance tests into the quote: product models, STC or battery-subsidy maths, and DNSP/export notes must be explicit for /solar-calculators/off-grid-load-calculator. MrSolar’s three-quote flow for off-grid load calculator exists so you can reject proposals that skip workmanship warranty length, handover app ownership, or export-limit disclosure.
