I'm trying to model a PVT system which consists of clusters of different PVT modules that cogenerates electricity and hot water for showering. Hot water storage is achieved using a mains pressured 3 tank system. However I have not been able to model the 3 tank system using the available storage tank subroutines(type 4, 60, 534). Tank temperatures obtained are very low when compared to results from a mathlab simulation. Mass balance failures are reported in the list file, which i attribute to the incorrect connections between tanks. I believe the problem lies in the 2 way flow between tanks that is not corrected modelled in the simulation. Is there any way to correct this? I've attached a simple diagram of the system i'm trying to model. Does anyone have prior experience with multi tank setups and can provide some guidance? Thanks, Jesper
