Start with solar. Add the rest when you are ready.
Microinverters for balconies, roofs and gardens — and a clear path to storage, EV charging and monitoring on the same platform.
Any surface that sees the sun.
The same microinverters work on a balcony railing, a pitched roof, a flat roof or a garden frame.




Plug-in connection must comply with local regulations; permitted power, socket type and registration differ by country.
Five steps, one platform.
Each step adds to the one before, on the same platform.
- 01Plug-in



Plug-in solar
Start with SolarCore microinverters, one MPPT per module. A single unit up to 800 W — such as the VM800WE-P2 or a SolarKit — plugs into a household socket where local rules allow; in countries with higher plug-in limits, the four-module P4 can connect by plug too. Larger arrays on an AC trunk cable are installed by an electrician.
- Lower daytime grid use
- No building work
- Wi-Fi pairing in about 10 seconds*
- 02Storage

Add storage
PowerCube keeps daytime solar for the evening and backs up essential circuits. Its four PV inputs take panels directly, existing microinverters can stay, and SolarCore microinverters add more solar over the home's AC wiring — coordinated by EnergyPilot.
- Solar in the evening
- Backup in 10 ms or less
- 2.5 to 27.5 kWh
- 03Charging

Add EV charging
A ChargeFlow wallbox charges the car from surplus solar; EnergyPilot measures the grid connection and keeps the main fuse within limits.
- Drive on your own solar
- Dynamic load balancing
- Export limitation
- 04Control

Control with EnergyPilot
EnergyPilot measures at the grid connection and decides on site where every watt goes: zero export or a set feed-in limit, battery dispatch and EV surplus charging — even when the internet is down.
- Zero export or feed-in limit
- Battery and EV surplus in one plan
- Works offline
- 05Monitor

Monitor and optimise
VIP Cloud shows generation, storage, charging and consumption live, with time-of-use strategies and a local mode that works offline.
- Live data every second
- Plant sharing
- Local mode
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. SolarCore systems on an AC trunk cable, PowerCube VA2000D and above, VB5000D packs, SolarHub, ChargeFlow and EnergyPilot are installed by a qualified electrician. PV input max. 60 V DC — check module Voc at the lowest expected site temperature. *With good signal, a working network and a normal device connection.

Zero export where the grid requires it.
In some countries and grid areas, solar power may not be fed into the grid, or only up to a set limit. EnergyPilot sits in the distribution board, measures at the grid connection with clip-on CTs and regulates SolarCore, SolarHub and PowerCube on site — surplus goes to the home, the battery or the car first.
- Zero export or a set feed-in limit
- Single-phase VDG-EM-1 or three-phase VDG-EM-3, ±1% accuracy
- Decides locally and keeps working when the internet is down
- Third-party inverters can be monitored, but not controlled
Installed by a qualified electrician. Which export limit applies depends on the country and the grid operator.
Several microinverters, one AC trunk cable.
On a roof, each microinverter clicks into a T-connector on the AC trunk cable, which runs to its own breaker in the distribution board.
- Units per branch depend on the model and the cable cross-section
- SolarCore P4 (four modules per unit) is made for rooftop and garden arrays
- End cap seals the open end of the trunk
- 1, 2 and 4-MPPT models for different module layouts
