Anker is turning the kind of portable batteries you throw in your backpack into something a lot more ambitious: a whole-home backup platform that wants to sit in the same conversation as Tesla Powerwall and EcoFlow’s high-end systems. Instead of just keeping your phone alive on a camping trip, the SOLIX E10 is designed to quietly take over your house when the grid gives up, and to shave money off your bill the rest of the time.​

At the heart of the setup is the SOLIX E10 “big battery,” a modular system built around a chunky inverter Anker calls the Power Module and a stackable 6kWh battery block. Out of the box, a single E10 base system can output 7.68kW continuously, with a “turbo” mode that pushes that to 10kW for up to 90 minutes, which is enough muscle to run big-ticket items like central air, electric ovens, and EV chargers without feeling like you’re playing power-strip Tetris. Anker rates a one-battery setup at up to 28.8kW of peak power and bumps that to 37.2kW when you attach at least two batteries, so short, heavy surges like starting a five-ton AC compressor are firmly in range.​

Where things get wild is when you start stacking. Anker lets you combine up to three fully loaded E10 systems, bringing total battery storage to 90kWh and solar input capacity to 27kW across the house. For context, the average US home chews through roughly 29.2kWh of electricity per day, so a maxed-out install could theoretically carry you for about three days with no grid at all, assuming you’re not trying to reenact Times Square in your living room. That kind of capacity pushes the SOLIX E10 into small-business territory, not just residential backup.​

But most homeowners aren’t going to drop straight into a 90kWh monster, and Anker knows it. The company pitches the E10 as something you can grow into: start with a base system for critical circuits and add batteries, solar, and extra units as your budget and needs evolve. The entry configuration starts at around $4,299 for one inverter and one battery, which puts it in the same psychological price band as a single Tesla Powerwall 3, though Tesla’s unit packs 13.5kWh per battery and offers 11.5kW of continuous power on its own. Once you tack on Anker’s smarter hardware—the Smart Inlet or the Power Dock panel—the price climbs into the mid four figures and then the $7,000-plus range if you want the bundled generator kit.​

The real differentiator for Anker isn’t just the battery stack; it is the way the entire ecosystem is wired together to feel “set and forget.” The Power Dock is essentially Anker’s take on a modern electrical panel with brains: it can automatically transfer up to 12 circuits (200 amps) to backup in under 20 milliseconds, fast enough that your lights and computers shouldn’t so much as flicker when the grid drops. That near-instant switchover is a direct shot at Tesla and EcoFlow, both of which lean on gateways and smart panels to juggle home loads but typically talk in terms of “seamless” transitions without calling out numbers that low. If you don’t want to swap your whole panel, Anker has the Smart Inlet Box, a simpler manual option that still gives you a clean way to feed backup power into existing circuits.​

Then there’s the generator. Instead of treating fossil backup as an afterthought, Anker is building it into the story with the Smart Generator 5500, a weather-resistant, tri‑fuel unit that can run on gasoline, propane, or natural gas. It can fire up automatically to extend your runtime when the batteries run low, essentially turning the SOLIX E10 into a hybrid system that behaves more like a tiny, software-defined microgrid than a simple battery in a box. Anker claims up to five times longer backup time with its smart generator approach compared to conventional setups, thanks to smarter dispatching and tighter integration with the batteries.​​

All of this lands at a time when “whole-home backup” is becoming less of a luxury feature and more of a coping mechanism for an aging grid and increasingly weird weather. Tesla’s Powerwall 3, for example, is explicitly marketed as a way to keep your house fully functional—HVAC, refrigerators, cooking, home office, even EV charging—with 11.5kW continuous output when paired with the right gateway and panel hardware. EcoFlow, on the other hand, has been leaning into modular storage plus smart gateways that blend solar, batteries, and generators automatically, promising “genuine energy independence” in places where blackouts and peak pricing are now just part of life. Anker is clearly eyeing that same customer, betting that its brand recognition from chargers and power banks can translate into trust at a much bigger, more expensive scale.​

For homeowners, the pitch is straightforward: instead of a noisy standby generator that clunks on after 10 to 30 seconds of darkness, you get an all-metal, outdoor‑rated battery system with automatic switchover in less than the blink of an eye. You can feed it from rooftop solar during the day, rely on the batteries as a buffer during peak pricing windows, and let the smart generator kick in only when things get really hairy. Over time, that combination of bill optimization and resilience is what justifies the upfront cost—especially in states where utilities are raising rates while reliability heads in the opposite direction.​

Of course, this is still the early days for Anker at house scale. Whole-home systems live and die on installer networks, local permitting, utility interconnect rules, and long-term service support, not just on spec sheets and slick landing pages. Tesla has a decade of Powerwall deployments behind it, and EcoFlow has been steadily building credibility in portable and residential storage before stepping into whole-home gateway territory. Anker will have to prove that its “hassle-free, one-stop installation” promise is more than a marketing line—and that parts, support, and app updates will still be there many years into the 10‑plus‑year lifespan homeowners expect from systems like this.​

Still, there is something very on‑brand about Anker showing up at the whole‑home party with an aggressively specced, modular rig that tries to do a little bit of everything. If the company can nail the boring stuff—permits, installers, support—it suddenly becomes a serious contender for anyone shopping beyond Tesla’s ecosystem or looking for a hybrid solar‑battery‑generator setup out of the box. And if you’ve ever reset a Wi‑Fi router after a storm blackout or watched your fridge count down through a long power cut, the idea of your house quietly handing power duties over to an oversized “battery bank with brains” starts to feel less like a gadget novelty and more like the new normal.​
