Jackery Energycore: 100kWh Home Battery Debuts at IFA Berlin 2026

Jackery is showing the Energycore, a 100kWh liquid-cooled residential battery, at IFA Berlin 2026 (Hall 2.2, Stand 114, 4–8 September). It's paired with a new PowerVault 50 three-phase hybrid inverter, and the pairing is a different animal from the rest of Jackery's Berlin line-up: it's built for larger homes and off-grid sites, not the balcony-scale storage of the SolarVault 3 or the portable Explorer Plus v2. Jackery didn't have a dedicated display explaining the system in depth on the show floor, but confirmed the specs below and said more detail is coming.

What the Energycore + PowerVault 50 system is

Energycore is a floor-mounted outdoor battery cabinet built around an 800V lithium-ion architecture (120V–800V operating range), storing 100kWh in a single unit. Jackery says it runs a liquid-cooling system that holds cell-to-cell temperature variance to within ±3°C — tighter thermal control than the air-cooled home batteries most UK installers currently fit, and a meaningful factor in long-term cycle life at this scale. Maximum charge/discharge current is rated at 2 × 80A. The matching PowerVault 50 inverter delivers 50kW nominal AC output at 230/400V with full three-phase, 100%-unbalanced-load support, and takes up to 100kW of solar input across four independent MPPT trackers (150–950V DC window). Jackery quotes a peak efficiency of 98.6% and says the inverter supports DC/AC oversizing up to 200% — useful where a site has more panel capacity than the inverter's nominal rating. For scale, that's roughly six times the top capacity of the modular SolarVault 3 stack (up to 45.36kWh across three paralleled units).

Built for installation by machinery, not by hand

At around 1.5 tonnes, Energycore isn't a unit an installer wheels into a utility cupboard. The cabinet has four crane hooks built into the housing specifically for lifting it into place, and Jackery has designed the whole package around logistics: getting it off a lorry and onto a base pad is expected to need a small crane or similar plant on site, not just a two-person installer team. That's a genuinely different installation model from anything else in Jackery's current range, and it signals the system is aimed at new-build, commercial-adjacent or off-grid projects with proper groundworks — not a retrofit add-on for an existing UK semi. Backup performance is rated for 150% peak capacity (75kW for 10 seconds) with a sub-10-millisecond UPS transfer time and black-start capability, plus a dedicated 50kVA diesel generator port for hybrid off-grid setups. The cabinet carries an IP66 ingress rating and an operating range of -40°C to 60°C, both wider than the IP65 and -20°C-to-55°C figures Jackery quotes for the smaller SolarVault 3.

Safety claims: the same FortiShield framework, at a bigger scale

Jackery is applying its FortiShield safety system, announced across its wider IFA 2026 range, to Energycore too: cell-level origin protection, intelligent BMS monitoring, heat-insulating structural design, fault and emergency protection, extreme-environment resistance and end-to-end data privacy. As with the rest of the FortiShield claims, none of this is independently audited — it's Jackery's own framework, applied consistently across tiers rather than unique to this product. At 100kWh in a single cabinet, thermal and fire-safety engineering matters more than it does for a portable power station, so how these claims hold up under UK certification (BS EN, UL 9540A-style testing) is worth watching once Jackery publishes third-party test data, rather than taking the marketing framework at face value.

Availability: Jackery says 1-2 years, not now

This is the important caveat: Jackery representatives at IFA told press the system is roughly 1-2 years away from production and retail availability, while the company finishes the build and works out a go-to-market strategy. Energycore at IFA 2026 is a prototype-stage showcase, not a product with a price list or an order date — there's no UK launch window, no confirmed pricing, and no confirmed installer or MCS-certification route yet. Treat every spec above as Jackery's stated design target rather than a shipping product's verified performance. For anyone who needs storage now rather than in 1-2 years, our best home battery storage UK rankings and commercial battery storage guide cover what's actually installable in the UK today, including at the larger end of the market this system is aimed at.

Jackery also used the same stand to show a smaller-scale whole-home product, the EnergyGuard Max, which pairs a built-in hybrid inverter with a claimed 10ms UPS-grade transfer time — a different system from Energycore, aimed at general whole-home backup rather than larger or off-grid installs.

We'll update this piece once Jackery confirms a firmer timeline, pricing or UK availability for Energycore and the PowerVault 50.
