Power Systems Warehouse - New Automatic Inverter System saves up to 70% of Generator Fuel!

Power Systems Warehouse has recently installed its innovative generator inverter systems into 2 rural off-grid homes. The owners asked for these Powerguard PS Systems to be added to their electricity power generators. The projects required an understanding of their domestic mixed load applications through a 24 hour cycle. They started and stopped their generators manually and ran them to give sufficient power for any load during the period they needed them on.
The Powerguard PS System was installed between their generator and domestic circuit. It is programmed to automatically switch on the generator for times of known heavy domestic use and utilises the excess power to charge storage batteries. The aim is to reduce generator run time to less than 33% so that in any 24 hour period the generator has to run less than 8 hours. The charger is capable of recharging the battery in less than 8 hours.
To prevent damage to the battery the charger has a sophisticated microprocessor control that will charge fast but not overcharge. If the battery becomes charged and the generator is still running the PS System’s charger will go into float mode and keep the battery fully charged without damage.
When the generator is not running, the PS System’s inverter converts the DC battery power to AC power. The inverter output is a low distortion sine-wave, the same as or better than, the utility mains supply. It is stable, clean and regulated and is suitable for all electrical equipment designed to be powered from the utility mains supply.
If at any time there should be an extra load applied to the domestic circuit above the inverter rating or battery capacity, the generator will be automatically started until that extra load has stopped.
The customers have been delighted with the results, noting that their generators are now fully automatic and reporting that their fuel consumption is now less than one third of that before the PS System was installed. Additionally generator run time and maintenance costs will be reduced by two thirds.
There is further potential to provide an even more eco-friendly power system, if the battery could also be charged from another source the generator run time would be reduced even further.
A wind generator or solar panels can be connected to the system achieving greater efficiency. The fuel for the generator is usually red diesel oil. Greener alternatives such as bio-diesel and vegetable oil can be carbon dioxide neutral because the gas has been absorbed from the atmosphere whilst the plant was growing and it is simply returned when it is burnt.
