Ferroamp EnergyHub Wall inverter 3-phase 21K (21 kVA)

The Ferroamp EnergyHub Wall 21K is a bi-directional 3-phase inverter that forms the bridge between the AC grid (230/400 V) and the Ferroamp DC nanogrid (760 V DC). It links PV (via SSOs), battery storage and smart energy control to a single scalable system, with real-time measurements and communication via the DC bus.

Ferroamp EnergyHub Wall 21K – 3-phase bi-directional inverter for Ferroamp DC nanogrid

The Ferroamp EnergyHub Wall 21K (21 kVA) is the heart of a Ferroamp installation: a bi-directional inverter that effortlessly converts energy from AC → DC and from DC → AC. With it, you connect the public grid (3-phase) to Ferroamp’s local DC nanogrid, to which you connect PV via Solar String Optimisers (SSO) and energy storage, among others. The result: a sleek, modular system ready for growth (more PV, more storage, more load capacity) without having to reinvent your entire installation.

Why this is a fine “building block”

  • Bidirectional: charges (AC→DC) and discharges (DC→AC) smartly, depending on your energy demand.
  • DC nanogrid (760 V): PV and storage on the DC side = fewer conversion steps and clear system construction.
  • Measurement = knowledge: measure AC (3-phase) as well as DC (voltage/current) for monitoring and optimisation.
  • Communication via DC bus with narrow-band PLC: less loose data cables, but smart control.
  • Scalable: up to 4 units in parallel (up to 112 kVA total).

  • Connection terminals: Phoenix VC-AMC-5 (AC) and VC-AMC-4 (DC), screw terminals up to 10 mm² max.

Installation tips (saves hassle)

  • IP21 = interior: place the EnergyHub Wall in a dry technical room or cabinet (not outside in all weathers).
  • Consider cooling: keep sufficient space around it and avoid mounting it in a place that gets structurally hot (directly next to heat source/sun radiation).
  • DC bus planning: keep the DC bus cable route logical and service-friendly; as a guide, a maximum DC bus cable length of 200 m is mentioned (for longer distances: design in consultation).
  • Parallel expansion: want to scale up later? In your distribution cabinet/main connection, keep space in advance for additional EnergyHub’s (up to 4 in parallel).
  • Measurement for smart functions: for functions such as phase/power balancing and analysis, measurement components (such as current transformers) belong in the system design.
