Jackery has launched 3 new SolarVault 3 Series ESS for greenfield as well as retrofitting solar-plus-storage projects
The SolarVault 3 Pro model supports a power output of up to 1,200 W, while the SolarVault 3 Pro Max is rated for up to 2,500 W
The SolarVault 3 Pro Max AC model, however, is developed as a storage-only solution
Jackery, a US-based maker of energy storage solutions and portable solar generators, has launched its latest SolarVault 3 Series solar-plus-storage solutions for residential PV installations.
According to the company, this product portfolio comprises 3 new models, covering small-scale 600 W plug-in to large-scale PV applications. These are equipped with a hybrid inverter and vertically stacked LiFePO₄ battery units and are electrically integrated in an AC-coupled configuration.
The SolarVault 3 Pro model supports a PV array of up to 4,000 W, connected via 4 built-in independent MPPT channels. Without sharing technical specifications, the company states that this DC-side distributed architecture helps optimize PV input power. Unlike centralized or fewer MPPT-based configurations, its higher number of channels distributes the impact of partial shading or different module orientations over a roof. In addition to solar insolation utilization, it is equipped with a battery unit of up to 2.52 kWh to maximize solar harvesting and self-consumption. The company states that the capacity can be scaled up to 15.12 kWh by connecting 6 ‘modular’ units in parallel. In terms of AC power output, it is rated at 1.2 kW, sufficient to meet the 600 W Dutch plug-in solar compliance requirement.
While featuring similar technical specifications, SolarVault 3 Pro Max is designed to handle higher loads of up to 2,500 W.
Without sharing the C-rate of the batteries, which is needed to assess maximum backup duration, the company states that both products feature an emergency backup function. The ESS activates this function within a few milliseconds of grid outages or failures, without interrupting running loads. It also has a bypass function that bypasses the inverter and feeds the connected loads directly from the grid. It supports higher-load appliances without exerting additional stresses on the installed ESS, says Jackery.
The company also notes that it might be useful for existing prosumers who want to use excess solar energy and boost self-consumption by retrofitting this AC-coupled ESS. Unlike the DC-coupled alternatives that require replacing the existing inverter and rewiring of the PV array, its built-in battery inverter requires no modifications. On the capacity side, the former model allows up to 1,200 W while the latter supports higher AC-coupling of up to 2,500 W.
In terms of operations, which are typically complex and require real-time monitoring and controlling, these products use an energy management system (EMS). An AI algorithm integrated with this EMS analyzes solar generation, consumption, and battery status in real time. The EMS also supports regional electricity arbitrage by integrating with third-party platforms, such as Nordpool, Tibber, and Rabot.
On the safety side, these products feature an IP65-rated enclosure for ingress protection, enabling deployment in outdoor applications. They are also designed to operate in a temperature range of -20°C to 55°C without derating.
The third product, SolarVault 3 Pro Max AC, is a storage-only solution that supports AC coupling of up to 2,500 W.
The company states that it will begin pre-sales for this series from March 25 in the Netherlands, Germany, and France.
