Stand Alone Power

True Off-Grid Autonomy

The Ultimate Stand Alone Power System with 100% Renewable energy, clean, safe and requires no fossil fuel back-up

The Heart of the Solution is High Density Energy Storage

The key to successful Stand Alone Power Systems is the ability to store large quantities of Energy to cover periods of low or no renewable energy generation.  The very compact, Solid State Hydrogen Storage enables the storage of over 425kWhrs in the volume equivalent to a small garden shed.  This is enough power to run the average residence for over 20 days with zero solar or wind and of course no diesel.  That is real protection for the off grid user and ensures year round power supply.  The larger MEGA system can power the average residence for over 6 months and is in a single 20 foot container.  

In practice the system shifts excess power from summer to winter and from day to night.  Our SAP system can be modelled for long term certainty around supply and due to the economic nature of the storage, we supply far more stored capacity than other SAP systems.  Therefore the risk of supply outage is negligible and the requirement for diesel removed.  It is important to remember that the conditions that often cause renewable energy vulnerability such as fires, floods and cyclones often also make the delivery of diesel impossible.  With the H2G system you have all you need at your site for year round supply.
