Double Door 24.96kW Off Grid All in One Solution
5kW Off Grid Solar with 24.96kW Battery Storage Bank

$37,495.00

  • Free Installation and Delivery Australia Wide Included
  • Tier 1 Solar Panels
  • SMA Inverter and SMA Sunny Island 8.0H
  • 24.96kW AGM Giant Power Storage Bank
  • AC connection for auxiliary charging
  • Quick Installation & Turnaround Time

This double door system holds 24.96kW of AGM battery storage (8 x 520ah 6v batteries) with a 5000w (7500w surge) AC coupled SMA inverter and SMA Sunny Island 8.0H 6kW inverter charger .  The cabinet measures 1560mm wide by 5000mm deep and is 2090mm tall.  The battery bank is 48v and the system comes pre wired from the manufacturer which saves expensive installation costs. The inverter discharges the batteries down to 50% capacity to preserve the battery life.  This means 50% of the battery capacity is used which makes it a usable 12.48kW (24.96kW – 50% or 24.96kW x .50).  The AGM batteries set to 50% DOD (depth of discharge) will give you 2200 cycles or 7 years of life. All our Giant Power off grid all in one solutions have auto generator start AC connection ports allowing you to top up the batteries and provide power during sub optimal weather conditions.

Quadra Door 49.92kW Off Grid All in One Solution
9kW Off Grid Solar with 49.92kW Battery Storage Bank

$48,495.00

  • Free Installation and Delivery Australia Wide Included
  • Tier 1 Solar Panels
  • 2 x SMA Inverters and SMA Sunny Island 8.0H
  • 49.92kW AGM Giant Power Storage Bank
  • AC connection for auxiliary charging
  • Quick Installation & Turnaround Time
  • Remote Monitoring Software included

This quadra door off grid solution holds 49.92kW of AGM battery storage (16 x 520ah 6v batteries) with 2 x 5000w (7500w surge) AC coupled SMA inverters and the SMA Sunny Island 8.0H 6kW inverter charger.  The cabinet measures 3930mm wide by 500mm deep and is 2090mm tall.  The battery bank is 48v and the system also comes pre wired from the manufacturer which saves expensive installation costs. We set the inverters to discharge the batteries to 50% capacity to preserve the battery life.  This means 50% of the battery capacity is used which makes it a usable 24.96kW (49.92kW – 50% or 49.92kW x .50).  So as an example, a off grid house with 9kW of solar panels on the roof in Queensland will generate approximately 45-50kW per day which means 24.96 of the generated kW will be put into the batteries for evening use and the remainder will be free for the household to use while the sun is out.  Once the household enters evening hours, the residents will want to be mindful to the fact that there will be 24.96kW available to use until the sun comes out again.  All our Giant Power off grid all in one solutions have auto generator start AC connection ports allowing you to top up the batteries and provide power during sub optimal weather conditions.
