Power Backup

Are you worried about the consequences of your pumps not working,
in the event of a power outage?

Teknik Group designs, builds and installs power back up units for your pump system.

We take into account pump system size, discharge frequency, rainwater catchment area, and location.

We then advise the best options to suit your system and budget.

Our most popular options are Battery Backup Units, or Diesel Powered Generators.

The battery back up units range from small single battery units to large units capable with many batteries.

Our Diesel generators range from small manual start units, to full auto start with power switchover equipment.

Which one is better?

We often get asked which set up is best, and both systems have their advantages and disadvantages.

DIESEL POWER BACK UP

  • Noisy when running.
  • Noise will disturb neighbors.
  • requires exhaust pipework.
  • Diesel odours.
  • Requires 6 monthly maintenance.
  • May require council permission.
  • Can be topped up with fuel = long running.
  • Large and obtrusive.
  • High Costs.

BATTERY BACK UP

  • Small and neat in appearance.
  • Requires less maintenance.
  • Silent operation.
  • Full automatic operation.
  • Mains power keeps the batteries charged when not in use.
  • Can be built with a Hybrid solar charging system
  • The system is sized to give long run times
  • There is the option of a plug in for a small portable generator to charge the batteries
  • Environmentally friendly
  • Battery technology has come a long way.

POINTS TO CONSIDER.

  1. A pump system does not run constantly, and the actual pump run time is usually less than one minute.
  2. We calculate the catchment area size and combine this with pump discharge size, along with the average rainfall of a storm and general rainfall. Australia tends to have rainfall in “Showers” which can be carefully calculated to give the pump run times over a period of 3 to 5 days.
  3. With a typical battery back up unit, the minimum run time is 4 hours of continuous pumping. The likelihood of the pump running continuously for this time is highly unlikely.
  4. A larger battery back up unit can run the pumps for over 10 hours constantly.
  5. The Battery back up can also be connected to our remote monitoring system, giving an alert as to power outage, and information about the battery charge.
  6. We often put a standard power point onto the battery back up, allowing phones to be charged, lights connected etc.
  7. A Diesel Generator cannot be started and stopped every time the pumps start and stop. This would quickly flatten the start battery due to their not being enough run time for the built in charging unit to charge the battery.
  8. A Diesel Generator is typically set up to start when the pumps require power and then to continue running for an extra 10 minutes to give the starting battery time to charge, and the engine to Lubricate.
  9. This starting and stopping is noisy and disturbing to not only the property owner, but also Neighbors.
  10. Even though the diesel generators are silenced, the noise still means you cannot be too close to them when they are running.

Overall, the popularity of a diesel power back up system has dropped in recent years due to the price of batteries becoming cheaper and technology in capacity improving all the time.

A Diesel system with exhaust pipework starts at a minimum of $8000

A Small battery unit for a 250W storm water pump starts at $2500
