The modular, reliability-first choice - especially for homes already running Enphase microinverters. Each 5kWh module contains six grid-forming microinverters producing 3.84kW continuous (7.68kW peak for motor starts), and you stack modules to fit the budget. Price shown is typical installed cost per module ($5,000-8,000 depending on region and whether a System Controller is included). The 15-year/6,000-cycle warranty is the longest in the industry by five years, and it's the spec owners cite most when justifying the premium. The criticism is always the same: per-kWh cost runs $1,000-1,600 installed - roughly double a Powerwall 3 - and whole-home backup realistically needs three-plus modules and the IQ System Controller before it starts a heat pump. Owner sentiment on the Enphase app and the no-single-point-of-failure architecture is very positive; sentiment on the final invoice less so.

The default add-on for the millions of homes already running SolarEdge inverters. Its DC-coupled architecture is the technical selling point: solar charges the battery without a DC-AC-DC round trip, giving 94.5%+ efficiency - the best path from panel to stored kWh of anything here. 9.7kWh usable, 5kW continuous (7.5kW/10s peak), stacking three-high to 29.1kWh on one Home Hub inverter. Price shown is a typical installed cost; projects commonly land $7,000-15,000 depending on region and wiring. The caveats owners raise: it's NMC chemistry in an increasingly LFP world, 5kW continuous won't start big HVAC without careful load design, it only works within the SolarEdge ecosystem, and SolarEdge's post-2023 corporate turbulence plus mixed support reviews give some buyers pause. For existing SolarEdge homes though, nothing else integrates as cleanly.

Anker's professionally-installed system, built from slim 5kWh modules into the best-looking cabinet in the business - reviewers keep calling it the battery you don't need to hide. Price shown is a typical installed 15kWh configuration (~$9,750-11,000 hardware plus $1,500-5,000 installation). The 6kW/12kW-peak power module handles essential-loads or whole-home duty, modules run at full power from -4°F thanks to per-pack thermal management, and systems parallel to a monstrous 180kWh. Reviewers praise the modular economics - add 5kWh at a time instead of a whole second cabinet. The catch owners and forum threads flag: the certified-installer network is much thinner than Tesla's or Enphase's, so quotes swing wildly and some regions simply have no coverage; the app is solid but young; and 12kWh usable from the '15kWh' stack (90.2% round-trip) needs reading of the fine print.
