Highlights

One unit for solar, battery and grid.

Up to 3,000 W solar
Four MPPT inputs (VH2000D–VH3000D); VH800D up to 2,000 W.
Storage when you want it
1 to 5 VB5000D packs, 5–25 kWh; packs can be mixed.
Backup in ≤ 10 ms
Up to 3,000 W backup on every model: 2,500 W from one pack alone, 3,000 W with two or more packs or with solar.
Outdoor, fanless
IP66, −40 to 65 °C, 6.8 kg, wall-mounted.
Fire suppression in every pack
Each VB5000D uses LFP cells and its own aerosol fire suppression unit, which activates automatically.
Self-heating batteries
VB5000D packs warm their cells automatically in the cold before charging or discharging.

On-grid, backup and off-grid

One unit, three ways to run.

SolarHub runs with the grid every day, keeps the lights on when it fails and can supply an off-grid site — with at least one VB5000D battery pack.

On-grid

Solar supplies the home first. Surplus charges the battery for the evening; the rest can be exported, or limited to zero with EnergyPilot.

Rated on-grid output 800–3,000 W by model
Up to 3,000 W solar input on 4 MPPTs
Without a battery it works as a PV microinverter

Backup and off-grid operation require at least one VB5000D battery pack. Battery alone: 2,500 W with one pack, 3,000 W with two or more.

Typical configurations

Sized from a small array to the whole roof.

Small array

VH800D + 1 × VB5000D

5 kWh · 800 W AC · 2,000 W solar · up to 3,000 W backup*

Rooftop

VH3000D + 2–5 × VB5000D

10–25 kWh · 3,000 W AC · 3,000 W solar · 3,000 W backup

Weak grid

VH2000D + 1–3 × VB5000D

5–15 kWh · 2,000 W AC · 3,000 W solar · up to 3,000 W backup*

* 2,500 W from one pack alone; 3,000 W with two or more packs, or with solar supplying at the same time. Typical configurations are for guidance only — size each system to the site and local regulations. SolarHub and VB5000D packs are installed by a qualified electrician.

Modular storage

Add packs as you go.

Configuration	VH	VH + 1	VH + 2	VH + 3	VH + 4	VH + 5
System capacity	Solar only	5 kWh	10 kWh	15 kWh	20 kWh	25 kWh
Battery-only AC output	–	2,500 W	3,000 W	3,000 W	3,000 W	3,000 W
Stack height (packs)	–	323 mm	646 mm	969 mm	1,292 mm	1,615 mm
Stack weight (packs)	–	41 kg	82 kg	123 kg	164 kg	205 kg

Battery-only output; total on-grid output is limited by the VH model rating (800 / 2,000 / 2,500 / 3,000 W).
Battery packs only, excluding base and brackets. SolarHub is wall-mounted separately. Secure every stack with the anti-tip accessory.

Smart energy management

Solar first, stored for the evening.

Self-consumption

Solar first; surplus charges the battery for the evening.

Time-of-use

Charges in cheap hours and supplies at peak prices.

Backup reserve

An adjustable state-of-charge reserve for outages.

Zero export

Grid feed-in limited via the EnergyPilot local controller.

Solar forecast

Plans charging around the expected solar yield.

AI scheduling

Learns your usage and optimises charging in VIP Cloud.

Keep module Voc below 60 V at the lowest expected site temperature — Voc rises in the cold.
Rated on-grid power is reached with PV and battery supplying together; without a battery, output follows the available PV power.
Backup requires at least one VB5000D. Battery alone: 2,500 W with one pack, 3,000 W with two or more.
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.
