How it grows

Starts at 2.5 kWh. Stacks to 32.5 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 six packs.

2.5 kWhVA

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.

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.

Typical configurations

From balcony to whole home.

Balcony

VA800D (+ 1 × VB5000D)

2.5–7.5 kWh · 800 W AC · up to 3,600 W backup*

Garden

VA2000D + 1–2 × VB5000D

7.5–12.5 kWh · 2,000 W AC · 3,600 W backup

Rooftop & retrofit

VA3600D + 3–6 × VB5000D

17.5–32.5 kWh · 3,600 W AC · 3,600 W backup

* 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.

IP66 housing for the utility room, the garage or an outside wall. Stacks stand flush, with the anti-tip bracket on top.

Illustrative images. Installation, cabling and number of packs depend on the site; outdoor and fixed installations by a qualified electrician.

New and existing packs can be mixed. For more capacity, three or more systems can run in parallel.
Battery-only output; PV makes up the rest. Grid output is capped by the VA rating (800 / 1,200 / 2,000 / 2,500 / 3,000 / 3,600 W); backup output is 3,600 W on all models.
Calculated from module dimensions and weights, excluding base and brackets. Secure every stack with the anti-tip accessory. The VA + 6 × VB5000D configuration requires additional anti-tip reinforcement.
Keep module Voc below 60 V at the lowest expected site temperature — Voc rises in the cold.
Rated power is reached with PV and battery supplying together. Battery-only AC output: 1,200 W with 2.5 kWh, 3,600 W with 7.5 kWh or more.
Values measured in the VaySunic laboratory under specific test conditions; they are typical values, not warranted values.

* VA and VB5000D enclosures are rated IP66; the EPS socket is rated IP65. ** Cycle life measured under laboratory test conditions; actual life depends on temperature, charge/discharge rate and depth of discharge. *** On-grid output depends on the model and local limits. Off-grid needs PV and battery together, or 7.5 kWh or more; built-in 2.5 kWh alone: 1,200 W. Nominal battery voltages describe the modules. PowerCube uses module-level DC/DC control between modules. The Battery Optimizer is a dedicated DC/DC converter in each module. Diagrams and app screens are illustrative. Supported combinations of battery capacity, state of charge, state of health and hardware versions are determined by the system compatibility requirements. Protection functions describe design features and do not guarantee the outcome of any specific event. Always install according to the manual and local regulations.

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.
