Standalone UPS (Uninterruptible Power Supply)
When planning business continuity, a centralised UPS is normally more powerful, functional, sophisticated and automated than a solution based on a distributed architecture. What’s more, it’s usually housed away from the main data centre. Distributed UPS, however, is simpler and less costly to install; vital equipment can be protected independently, and thus it is shielded from a central power outage.
This standalone UPS (Uninterruptible Power Supply) situated at Stand Alone (solar) Power Systems provides back-up power for the office and workshop. With the advent of power failures this storm season, an UPS is ideal for complete back-up of computers, faxes, printers etc to keep you in business form halting.
The UPS does not have to be a complex system, all it does is to provide enough power to run essential appliances from a few hours or several days, depending on how critical the application is. The one pictured here is over-engineered for its application, however can run the office and workshop for 1 week with a blackout of the mains electricity.
Standalone Power Systems can design and supply an UPS depending on your needs and budget, the charger can be installed on an off-peak tariff to save costs. In this scenario only an off peak tariff chargers will be applied while you’ll have the additional benefit of continuous, uninterruptible power.

Centralized ups
A centralised UPS solution is where a single UPS is utilised to feed a dedicated ring main which supports numerous items of critical load. The alternative solution is a distributed / decentralised one, where each piece of equipment is powered by a smaller individual UPS.
A centralised UPS system is normally, in terms of utilisation of load and battery capacity, far more versatile and cost efficient. However, the installation of a dedicated ring main can be expensive – especially if the items of load are widely spread throughout a building.
While a distributed / decentralised solution may not optimise load capacity and hold up time, the effects of UPS failure are reduced when compared against the effects of the failure of the centralised UPS.
Centralised UPSs are highly reliable as they provide N+1 parallel redundant module.
Inverter chargers
Inverter Chargers are devices that convert direct current (DC) to alternating current (AC), and power a variety of equipment, including power tools, computers, appliances, and more.
Inverter chargers combine an inverter and a battery charger in one complete unit. They can be used with a solar PV array or wind turbine power system or when another there is another AC power source available, such as a diesel generator or utility power. They can operate as uninterruptible power supplies (UPS). These intelligent devices can behave either as an inverter or a charger and can switch between one and other as required. Inverter chargers can be connected to the electricity grid, but they are not grid tied inverters.
Inverter Chargers are increasingly widespread due to the modest installation and reduced cost compared to separate units.
- Unprecedented surge capacity
- Efficient, power factor corrected, high-current, multistage battery charging
- 120/240 volt AC spilt-phase operation
- Dual AC inputs
- Integrated design to minimize external balance-of-system components
