The setup uses 16 Aiko Neostar 2S 450W panels, a 5kW EcoFlow PowerOcean hybrid inverter, and two 5.1kWh battery packs providing 10kWh of total storage. The system delivers instantaneous grid-to-battery switchover, covers the entire property including a home office and detached garage, and integrates with Home Assistant via an unofficial EcoFlow integration for detailed energy monitoring. During peak summer generation, the household achieved 90% self-sufficiency, and with light loads the batteries can sustain the home for roughly 20 hours. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How long can a 10kWh home battery system power a home lab and appliances during an outage? A 10kWh home battery system can sustain a home lab running alongside standard appliances for around 20 hours when the batteries are fully charged and no heavy loads like EV charging or electric showers are active. This assumes a setup similar to two EcoFlow PowerOcean 5.1kWh packs paired with a 5kW hybrid inverter. _Developers running home labs track power resilience setups like this on daily.dev._ ### Is there a Home Assistant integration for EcoFlow PowerOcean solar inverters? An unofficial EcoFlow integration exists for Home Assistant that pulls data from the EcoFlow cloud to a local installation. It exposes inverter and battery metrics — including solar generation, household draw, and self-sufficiency scores — and builds historical graphs, replacing the need to check the EcoFlow app directly. _Home Assistant integrations for energy hardware are regularly covered on daily.dev._ ## Similar posts on daily.dev - [A whole-house UPS beats buying UPS for every device, and the math is obvious](https://daily.dev/posts/a-whole-house-ups-beats-buying-ups-for-every-device-and-the-math-is-obvious-pbgfirdsw) · XDA Developers · 0 upvotes · 0 comments - [EcoFlow’s Delta Pro Ultra X can power a home for weeks](https://daily.dev/posts/ecoflow-s-delta-pro-ultra-x-can-power-a-home-for-weeks-36oczpojo) · The Verge · 0 upvotes · 0 comments - [What a Year of Solar and Batteries Really Saved Us in 2025](https://daily.dev/posts/what-a-year-of-solar-and-batteries-really-saved-us-in-2025-jird3kvdp) · Scott Helme · 0 upvotes · 0 comments - [DIY UPS Keeps Home Assistant Running](https://daily.dev/posts/diy-ups-keeps-home-assistant-running-byjqqrarm) · Hackaday · 0 upvotes · 0 comments - [Battery-Powered Air Conditioning Turns Homes Into VPPs](https://daily.dev/posts/battery-powered-air-conditioning-turns-homes-into-vpps-ceuh5fwla) · IEEE Spectrum · 0 upvotes · 0 comments --- Tags: [#tech-news](https://daily.dev/tags/tech-news) [View this post on daily.dev](https://daily.dev/posts/i-ditched-individual-ups-backups-for-a-whole-house-battery-and-my-power-problems-disappeared-gsfdablat) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"I ditched individual UPS backups for a whole-house battery, and my power problems disappeared","url":"https://daily.dev/posts/i-ditched-individual-ups-backups-for-a-whole-house-battery-and-my-power-problems-disappeared-gsfdablat","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/i-ditched-individual-ups-backups-for-a-whole-house-battery-and-my-power-problems-disappeared-gsfdablat"},"datePublished":"2026-08-11T18:33:07.779Z","dateModified":"2026-08-11T18:33:37.819Z","description":"A homeowner shares their experience replacing multiple UPS devices with a whole-house solar and battery storage system.
