Solar full off grid system

Full off grid solar system has been serving a 210msq house, only selling as we have put underfloor heating so needed to upgraded. 24volt system, All Outback system x3 Inverers x2 chargers, 18 panels, 4 have there own stand & the other 14 will need a frame or put on a roof. 1 wind turbine that is on an 8mtr pole currently not in use as needs a service. X12, 2 volt 1695 amp hrs gel battery's which are 5yrs old. All works well. The battery's are still getting charged by the 4 stand alone panels. The 14 panels have been professionally un-installed & the 4 on the stand currently still connected to keep batteries charged. The system is still complete & powered up but not connected to the house anymore. Will be removed & disconnected on purchase.
