Highlights

Starts small. Stacks up.

  • Up to 27.5 kWh

    2.5 kWh built in, plus up to five 5 kWh VB5000D packs.

  • Backup in ≤ 10 ms

    Up to 3,000 W continuous, 4,500 W for 15 s, on a dedicated EPS port — 1,200 W from the built-in battery alone.

  • Fire suppression in the VA and every pack

    LFP cells, plus an aerosol fire suppression unit in the VA and in each VB5000D that activates automatically.

  • Self-heating for cold climates

    Cold cells are warmed automatically before charging or discharging, so the battery keeps working from −20 to 55 °C.

  • 4 MPPT solar input

    Up to 3,000 W of PV, expandable with microinverters.

  • IP66, indoors or out

    VA and VB5000D are sealed to IP66 — garage, utility room or outside wall.

How it grows

Starts at 2.5 kWh. Stacks to 27.5 kWh.

The VA unit sits on top with 2.5 kWh built in. VB5000D packs of 5 kWh stack beneath it with flush fronts, up to five packs.

  1. One unit, 2.5 kWh built in.

    The VA is the hybrid microinverter and battery in one housing, with 4 MPPT solar inputs and a dedicated backup (EPS) port.

Heights and weights calculated from module dimensions and weights, excluding base and brackets. Secure every stack with the anti-tip accessory.

Modular storage

One VA unit, up to five packs.

New and existing packs can be mixed. For more capacity, three or more systems can run in parallel.

* 1,200 W from the built-in battery alone. VA800D may be connected by the owner where local rules allow; VB5000D packs are installed by a qualified electrician. Typical configurations are for guidance only; a dedicated protected circuit is recommended. Retrofit: add PowerCube and EnergyPilot to an existing PV system.

At home

Indoors or outdoors, it fits the space.

Design life15 years
  1. Keep module Voc below 60 V at the lowest expected site temperature — Voc rises in the cold.
  2. Rated power is reached with PV and battery supplying together. Battery-only AC output: 1,200 W with 2.5 kWh, 3,000 W with 7.5 kWh or more.
  3. Values measured in the VaySunic laboratory under specific test conditions; they are typical values, not warranted values.

A single plug-in unit up to 800 W (such as SolarCore VM800WE-P2 or SolarKit) and PowerCube VA800D may be connected by the owner where local rules allow; where national rules permit higher plug-in limits, SolarCore P4 can also be connected by plug. Other SolarCore systems on an AC trunk cable, PowerCube VA2000D and above, VB5000D packs, SolarHub, ChargeFlow and EnergyPilot are installed by a qualified electrician.
