Sunsynk 50kW HV Three‑Phase Hybrid Inverter 

Why choose this 50kW Sunsynk hybrid inverter?

  • 50kW three‑phase hybrid inverter for commercial and industrial sites, combining solar, grid and battery power in one flexible platform.
  • High‑voltage battery input and up to 65kW PV DC input for efficient large‑scale systems with room for future expansion.
  • Grid‑code compliant with UK G98/G99 standards, IP65 weather protection and UK‑based expert support from Energian.

Product overview

The Sunsynk 50kW HV Three‑Phase Hybrid Inverter is designed for medium to large commercial, logistics and light industrial installations that need reliable three‑phase power and smart energy management. It can manage energy from PV, batteries and the grid, helping sites cut daytime demand charges, support critical loads and add backup capability when paired with suitable high‑voltage battery storage.

Key features

  • 50kW three‑phase output with up to 55kVA maximum AC power and 1.5× overload capability for short‑term peaks (off‑grid mode).
  • High‑voltage Li‑ion battery input (160–800V) with dual battery ports and up to 50A + 50A charge/discharge current for scalable storage banks.
  • Up to 65,000W PV input, four MPPT trackers and eight DC strings for flexible array design on complex roofs or multiple orientations.
  • Three‑phase unbalanced output up to 83.3A, allowing realistic load sharing across phases in mixed‑use buildings.
  • High efficiency design with 97.6% max inverter efficiency and >99% MPPT efficiency for strong generation yields.
  • IP65 wall‑mount enclosure with intelligent air cooling, suitable for plant rooms and sheltered outdoor locations.

Typical applications

This 50kW Sunsynk hybrid inverter suits multi‑unit residential blocks, small warehouses, logistics depots, light manufacturing sites and agricultural buildings with three‑phase services. It can be used for self‑consumption optimisation, peak‑shaving, limited backup for critical three‑phase loads, or as part of a larger multi‑inverter system when designed and commissioned by qualified engineers.

Installation and UK support

Installation of the Sunsynk 50kW HV Three‑Phase Hybrid Inverter must be carried out by suitably qualified electrical contractors familiar with G98/G99, three‑phase systems and high‑voltage battery banks. Energian can connect you with trusted UK installation partners for full turnkey systems, including PV arrays, HV battery storage, switching and protection.

Our UK‑based technical team can assist with system design checks, product selection and commissioning queries for commercial and industrial projects. Contact us by phone, email or live chat, or arrange an in‑person consultation at our UK office for project support and procurement advice.
