BACK-UP SOLUTIONS

When the utility fails a back-up solution gives you power to run your essentials. There may be a delay between the utility going off and your power being on, but that all depends on the solution you choose.

ONLINE UPS

  • Double-Conversion Online UPS’ isolate the supply from the load, the result is no transfer time at all, and the load has a constant voltage source with no fluctuations.

  • No maintenance

  • No noise

INVERTERS

  • No maintenance

  • No noise

  • No delay in transfer time

GENERATORS

  • Lower cost

BACK-UP INVERTER SOLUTIONS

The recommended inverter topology is a low frequency transformer-based inverter. The loads connected to systems like these are generally highly inductive and capacitive loads as well as the longevity of the inverter running such loads depend on the topology.

The storage technology would depend on the frequency of the battery cycling, the temperature the batteries will be exposed to and whether or not the solution will be expanded to a solar PV solution in the future that might utilize battery storage for additional energy saving.

For solutions where the batteries will only be used for standby and the frequency of the battery utilization is less than once per week, the ambient temperature of the batteries are fairly constant and not exceeding 35°C; lead-acid batteries will suffice. Applications with the inverse of any of the above factors should utilize lithium batteries.

ONLINE UPS SOLUTIONS

Online UPS’ are made for sensitive loads and the inverter topology is less robust – in most cases high frequency switching transformer-less technology is used. This makes it a more feasible solution.

Most online UPS’s have unconventional voltage range which make them incompatible with conventional PV technology like MPPT solar chargers, for this reason, they won’t be cycled frequently also very often these batteries are installed in server rooms which have temperature control implemented, for both of the above mentioned, in most cases UPS’s make use of lead-acid battery technology.

GENERATORS

Small (<12kVA) portable generators should include functionality as: 

  • Pull or electric start. 

  • With or without an automatic voltage regulator (AVR) if used with an inverter or UPS then it should include this.

  • Generally, petrol engines. 

  • Generally, they aren't silent types. 

Large (>12kVA) stationary generators can include functionality as:

  • Manual or automatic start based on mains failure

  • Should have a decent automatic voltage regulator (AVR) – especially if it is to be used with inverter or UPS technologies.

  • Fuel type can be Gas (LPG or Natural) or Diesel engines

  • Automatic Transfer Switch (ATS) 

  • Protection devices that take care of overheating, oil pressure, output quality monitoring with automatic shutdown and more. 

  • Generally, they are silent types.
