    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. Ideal for running household appliances, IT and computer rooms, servers, commercial or other large electronic equipment.

    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 batteries, or keeping them topped up. If the mains power is suddenly cut off, the system instantly transfers the power input to the batteries and starts drawing energy from them 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.

    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 batteries.

    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 batteries are 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 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 36kW of continuous power, by connecting up to 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 2 x UPS units2 x parallel connection kits, 8 x 200Ah gel deep-cycle batteries4m tinned copper battery cablesbattery linking cables, 2 x thermal over-current circuit breakers and loose ring terminals for crimping.

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