Testimonials:

For the first time since we have owned the boat (28 years), we have more power than we need. Fantastic, and thanks again.

This Photonic Universe Uninterrupted Power Supply (UPS) system is suitable for both mains-powered and off-grid applications where a stable and reliable source of AC power is required. Suitable for large households, servers, datacentres, telecommunications or other commercial and industrial use.

In a mains-powered setup, the system ensures that the AC appliances are not interrupted even if the mains electricity is unstable, intermittent or the power is suddenly cut off. While the mains power is available, the system links it to the AC output to power connected appliances whilst simultaneously charging the battery bank, or keeping it topped up. If the mains power is suddenly cut off, the system instantly transfers the power input to the battery bank and starts drawing energy from it so that the load work is not interrupted. When the mains AC input power becomes available again, the system transfers the input to mains AC power.

Zero transfer technology allows for instant switching from mains to battery backup power, without the typical delay of 10-20ms. This UPS is ideal for sensitive electronics where a consistent power supply is required, such as computers, servers, equipment in datacentres and other IT equipment.

For off-grid systems with a generator, this UPS system can allow for continual power even when the generator is turned off. This allows users to achieve significant savings of fuel costs by only running the generator periodically - at the optimal power levels to charge the battery bank.

Featuring a dry contact port, the inverters can activate or deactivate relay switches or compatible generators automatically when the battery voltage falls below a user-defined level. For off-grid systems with a generator, this feature is useful as the relay can activate the generator to start charging the batteries when they are low.

The system can also be used for portable power applications, i.e. when the battery bank is charged in a location with mains electricity, and the system is then transported to a different off-grid location to provide power on demand on a temporary basis. 

This UPS system can be configured in a single-phase or 3-phase AC output, making it suitable for typical household / light industrial single-phase applications, as well as industrial and commercial 3-phase power supply applications.

This system also supports solar power input with no additional charge control equipment required. Users can simply connect a suitable solar array to start charging from solar power to save on electricity bills for mains connected systems, or in order to run a generator less frequently for off-grid systems.

The system can be easily expanded to generate up to 45kW of continuous power, by connecting 9 inverters in parallel (additional parallel kits required, one per inverter). The external battery bank allows for easy expansion or replacement, as well as straight-forward installation in irregular locations.

This package includes 3 x UPS units3 x parallel connection kits, a 24kWh 500Ah battery bank , 6m tinned copper battery cables, 3 x thermal over-current circuit breakers and loose ring terminals for crimping.

Please note: the inverters use predictive cooling logic to activate the fans, and are not suitable for installing in locations where silence is required.

Please note: due to our warehouse arrangements, the accessories may be shipped from a different warehouse to the hybrid inverters and battery bank, and therefore delivered in a separate package.

The battery bank is covered by a 1 year repair or replacement warranty provided by Photonic Universe. In the unlikely event that a defect is found and confirmed during this period, we guarantee that we will repair or replace defective items (at our discretion). The hybrid inverter is covered by a 1 year manufacturer warranty. For more information please refer to our Terms and Conditions.

For installation advice, please click on the Installation tab.

 

Please note: this UPS system uses off-grid inverters. Any other AC power sources, including mains, can only be connected to the inverter input AC terminals, and should be fully isolated from the inverter output AC terminals. If the AC output of the inverters come into contact with another source of AC power, the inverters will be damaged.
