15kW Zero-Transfer UPS Uninterrupted Power Supply System 24kWh energy storage

  

The UK solar power specialist Photonic Universe Ltd is proud to offer this Zero-Transfer UPS battery back-up system for applications requiring a constant, uninterrupted power supply. Includes 3 x 5000W 48V zero-transfer hybrid inverters, a 24kWh 500Ah battery bank and connection cables. No-quibble 30 days return period. 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.

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 both typical household / light industrial single-phase applications, as well industrial and commercial 3-phase power supply applications. This UPS system also supports solar power input with no additional charge control equipment required.

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 units , 3 x parallel connection kits, a 24kWh 500Ah battery bank , 6 m tinned copper battery cables , 3 x thermal over-current circuit breakers and loose ring terminals for crimping. The inverters use predictive cooling logic to activate the fans, and are not suitable for installing in locations where silence is required.

Maximum solar input power: 4000W. Maximum open circuit solar input voltage: 145V (open circuit). MPPT operating solar voltage: 60 - 115 V. Maximum solar charging current: 80A. Maximum mains AC charging current: 60A. Maximum combined charging current: 140A. Solar / AC charger max efficiency: 98%. Operating temperature: 0°C to 55°C.

Supplied with USB drive, PC connection cable and PC software CD. Size: 52.5 x 30.3 x 14 cm. Battery specifications (entire 48V battery bank). Charging voltage: cycle use 56.4V, standby use 54.8V.

Temperature compensation: cycle use -120mV/°C, standby use -72mV/°C. Size: 1290 x 1140 x 670 mm (when positioned in racking). Weight: 720 kg (including racking). 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. (tick the box "This is not about an item" if you don't know this item number).
