PEAK GENERATORS Off Mains ELECTRICITY System

We have developed an off mains electricity power system for customers that do not have mains utility power. The system uses the following components:

4.5kw low noise diesel generator (8.5kw diesel generator optional)
3kw pure sine wave inverter
management system
Battery bank

There are also optional parts to the system to help reduce reliance on a generator:

Wind turbine
Solar panels

System Basics

When the generator is switched off the inverter uses the battery bank to produce 230v electricity. (silent). In doing this the inverter slowly discharges the battery bank. (silent)

When the battery bank is discharged, the generator is automatically started to recharge the battery bank and simultaneously power appliances that are normally the responsibility of the inverter and battery bank. Electricity power remains constant throughout this process and the user would not notice the switchover apart from the generator starting.

By charging and powering loads simultaneously the system saves energy that would otherwise be wasted by running the generator on its own.

The user has the option of adding solar panels and wind turbine to reduce reliance on the generator and save more energy.

Grid independent systems are suitable for use where there is no mains supply available. They generally consist of:

Renewable energy charging resource (wind, hydro, solar)
Charge controller system for the renewable energy source
Battery set to store electricity
Inverter system to convert stored electricity into 230V AC mains quality electricity
Generator set for secondary power source

The renewable energy source is permanently connected to the battery set via a charge controller and provides power for battery charging whenever it is available. The inverter system utilises the stored energy in the battery to supply the AC loads. If during any time battery voltage is low or the load is particularly high the inverter can request additional support from the generator. The inverter will start the generator automatically and synchronise with it over a period of about 30 seconds. At this point it instantly switches the generator through directly to the loads thus leaving the inverter free to utilize spare capacity on the generator or battery charger. This ensures that when the generator is running it is utilised most efficiently. When the batteries have recovered sufficient charge or the high load is no longer present the inverter switches of the generator automatically and operation returns to normal. Today’s technology is now so far advanced that modern off grid systems operate seamlessly with an automatic switch over taking place in less than 20milliseconds.

Note: The above diagram is a simplified version of an actual installed system

The system is fully automatic:

Both the generator and the inverter are controlled by an automated management system which means you do not have to switch the generator or inverter on or off. Once programmed the system will switch each item on and off automatically.

The system is low noise:

You can program the system to remain silent at night. This will enable the generator to start in the day, but it will not allow the generator to come on at night. When the generator is switched off you get 230v electricity without a sound because the inverter runs off the batteries. When the batteries are discharged, the generator will automatically start to charge the batteries back up again.
