Photonic 20kW Zero-Transfer Uninterrupted Power Supply (UPS) System With 48kWh Energy Storage

The Photonic Universe 20kW Zero-Transfer Uninterrupted Power Supply (UPS) System with 48kWh energy storage is a powerful backup power solution designed for large households, data centres, telecommunications networks, commercial premises, and industrial facilities. Delivering a stable and reliable AC output, it is ideal for servers, IT equipment, household appliances, and other sensitive electronics where uninterrupted supply is critical.

Unlike standard UPS systems, this model features advanced Zero Transfer Technology, enabling an instantaneous switch from mains to battery power with no delay. This makes it the perfect choice for mission-critical applications, such as servers, datacentre equipment, and telecommunications hardware that require a continuous and stable energy supply.

In a mains-powered configuration, the UPS ensures connected appliances are protected from instability, interruptions, or complete outages. While the grid is live, it powers devices directly and charges the battery banks. If the mains supply is cut, the UPS instantly transfers to battery power, ensuring seamless continuity. Once mains electricity returns, the system switches back automatically and resumes charging.

For off-grid use, this UPS integrates smoothly with generators to maintain uninterrupted power. By only running the generator when needed to recharge the batteries, you can achieve significant fuel savings and extend generator lifespan. The built-in dry contact port allows the inverter to automatically activate or deactivate relay switches or compatible generators when the battery voltage drops below a set level.

The system is also suitable for portable energy use. The batteries can be charged in a mains-connected location, then the UPS can be relocated to provide temporary or mobile power in an off-grid environment.

With flexible configuration options, this UPS supports both single-phase and three-phase AC output, making it suitable for domestic, light industrial, and large-scale commercial power requirements.

Built-in solar charging compatibility means a suitable solar array can be connected directly without the need for extra charge controllers. This helps reduce electricity bills for grid-connected systems and cuts generator runtime in off-grid scenarios.

Supplied with 48kWh of external battery banks, the system provides extensive storage capacity that can be expanded or replaced as needed. For larger installations, up to nine inverters can be connected in parallel to deliver a total of 45kW continuous output (parallel kits required per inverter). This makes it a scalable, future-proof power solution for residential, commercial, and industrial applications.

Package Includes: 4x UPS units, 4x parallel connection kits, 2x 24kWh 500Ah battery banks, 8m tinned copper battery cables, 4x thermal over-current circuit breakers & loose ring terminals for crimping.
