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.

Operating modes

Four ways to run your battery, set in the app.

Pick a mode, change the settings and watch the day change: where the energy comes from and what it costs.

The reserve stays in the battery for outages.

Smart

Self-consumption: solar covers the home first, the surplus charges the battery and the battery supplies the home in the evening. With EnergyPilot, grid feed-in can be limited to zero. With a ChargeFlow wallbox, choose whether the solar surplus goes to the battery first or to the car first.

Best for Everyday use with as much of your own solar as possible.

Illustration: PowerCube VA2000D with one VB5000D (7.5 kWh, 2 kW), about 3 kW of solar, a typical home and an example tariff (0.20 / 0.30 / 0.40 € per kWh, feed-in 0.08 €). Modes are those shown in the VIP Cloud app and may be refined with software updates; available functions depend on the market. Zero export needs the EnergyPilot local controller; AI scheduling and dynamic tariffs work through VIP Cloud.

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.

2.5 kWhVA
290 mmAnti-tip bracketVA · 2.5 kWhVB5000D · 5 kWh

  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.

  1. New and existing packs can be mixed. For more capacity, three or more systems can run in parallel.
  2. Battery-only output; PV makes up the rest. Grid output is capped by the VA rating (800 / 2,000 / 2,500 / 3,000 W); backup output is 3,000 W on all models.
  3. Calculated from module dimensions and weights, excluding base and brackets. Secure every stack with the anti-tip accessory.
  4. Keep module Voc below 60 V at the lowest expected site temperature — Voc rises in the cold.
  5. 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.
  6. 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.
