Description
The SolarVault 3 Pro marks Jackery’s step into home solar storage: moving away from the portable power station you carry in your van, this is a system for on-site self-consumption, designed for the house, balcony, or small workshop. The idea is simple: you store the day’s solar energy (or off-peak electricity) and reuse it when it’s expensive or when the grid fails.
This is precisely where it makes perfect sense: for areas prone to repeated power cuts, it acts as an automatic backup, and the rest of the time it helps you chip away at your electricity bill. Its entry-level version starts at 2.52 kWh, with a robust solar input and a design intended for hassle-free installation.
Who is this kit for?
This is not a portable product, let’s be clear straight away: it’s aimed at home self-consumption and backup. Perfect for anyone wanting to reduce their bill with solar panels, secure their home in an area with frequent power cuts, or equip a city balcony. If you’re looking for a battery to take camping, check out the Explorer series instead; the SolarVault stays at home and works for you daily.
Key Features
At its core is a 1200 W bidirectional AC power (it can discharge and recharge from the grid during off-peak hours) and a 4000 W solar input distributed across 4 MPPTs, up to 5200 W when combined with a micro-inverter. The base capacity of 2.52 kWh can be significantly increased with modules. All using LiFePO4 chemistry, with AI-driven management that optimises energy usage automatically.
Self-Consumption and Off-Peak Hours
The money-saving principle: the SolarVault stores energy when it’s free or cheap (daytime sun, night-time tariff) and releases it during peak hours. In a region where the grid is unstable, it switches to backup mode to keep essentials powered. This is the “smart stationary” use we’re seeing more and more, halfway between comfort and economy.
Expandable, and Built to Last
Starting from 2.52 kWh, you can expand significantly by stacking modules, allowing you to go from a simple top-up to a truly serious home storage system over time. This is the advantage of such a system: you invest progressively, without having to buy everything again. The LiFePO4 chemistry aims for longevity, consistent with a product installed for years.
Plug-and-Play and Safety
Jackery highlights a plug-and-play installation without complex wiring or technical skills, which lowers the barrier compared to traditional residential storage. On the safety side, it includes temperature detection and integrated fire protection, the minimum one expects from a battery that lives in your home permanently.
