Critload

A compatibility engine that takes a home's specific critical loads (EV charger, HVAC, fridge, server rack) and cross-references them against the actual published specs of EcoFlow, Anker SOLIX, BLUETTI, Base, Enphase and Powerwall tiers to flag exactly which named products can and cannot cover the load.

01

What to build

  • MVP

    A structured database of surge/continuous wattage specs for the top 15 branded backup SKUs, paired with a load-input wizard that outputs a pass/fail compatibility grid per product, launched as a standalone web tool.

  • Why it can be better

    Every existing calculator, from GitHub scripts to Sol-Ark's vendor tool, outputs a generic kWh number; none flag that a $1,500 Pila can't run a Level 2 EV charger or heat pump the way this tool does by name.

  • Revenue model

    Lead-generation fees from battery brands and installers who pay per qualified match referred, plus a $9 one-time detailed PDF report for consumers who want the full compatibility grid.

  • Target user

    Homeowners with at least one demanding critical load (EV, HVAC, server rack) comparing specific branded products before buying.

Context

The opportunity this answers

Build a brand-agnostic backup-sizing and load-matching advisor that recommends the exact battery, inverter, and panel setup for a specific home.

Why now

Backup brands have just pivoted from single-purpose portable power stations to whole-home marketing, splitting the market into incompatible tiers right as low-upfront-cost entrants like Base Power change the economics of adoption, so buyers face more confusing choices exactly when volatile, storm-driven search spikes push them to decide fast without any neutral way to compare branded tiers against their actual home loads.

Back to the idea
  1. 01

    Nobody can size their system

    Buyers repeatedly ask how much battery capacity they actually need and get only anecdotal answers, with no reliable way to match capacity to their real home loads.

    Evidence

    Threads debate whether 1000Wh, 2000Wh or a full Powerwall-class system is the 'sweet spot,' and homeowners post asking what ties into the panel and handles everything automatically without a clear answer.

    Confusing backup tiers

    The market has split into tiers (plug-in batteries, stackable portable kits, full whole-home systems) with wildly different capabilities, and buyers can't tell which tier covers their specific critical loads like EV chargers or HVAC until after purchase.

    Evidence

    A $1,500 Pila battery is shown unable to run a Level 2 EV charger or central heat pump, unlike an Enphase or Powerwall system, illustrating how similarly marketed 'whole-home backup' products actually cover very different load profiles.

    Unsafe DIY backup hacks

    People resort to risky DIY setups (car batteries, EV alternator charging, spare Li-ion cells) because they can't afford or justify a five-figure branded system, but lack basic guidance on inverter sizing, wiring safety, or load calculations.

    Evidence

    One post asks how to wire car batteries to an inverter and calculate home energy usage with no clear answer, while another describes rigging an EV's 12V alternator through an EcoFlow charger to keep a separate battery topped up.

    Server-rack backup underserved

    Niche always-on use cases like home server racks need backup sized for graceful shutdown runtime rather than whole-home coverage, and existing whole-home marketing doesn't address this segment.

    Evidence

    A homeowner building a NAS and network rack asks specifically for backup power sufficient for graceful shutdowns during extended outages, a need distinct from whole-home battery marketing focused on fridges, HVAC and EVs.

    Battery vs generator tradeoff unclear

    Reviewers and buyers weigh battery systems against generators but face conflicting signals on long-term reliability versus convenience, without a neutral way to compare total cost and coverage across fuel and battery options for their specific home.

    Evidence

    Wirecutter notes battery-backup is a 'compelling alternative' to standby generators but still trails on proven long-haul reliability, citing a five-year Generac warranty versus decades of generator service life, leaving buyers to weigh tradeoffs alone.
