DC coupling Battery Storage not charging

Hi There,

I've ran into an issue with using battery storage in the model. The site i'm modelling is a depot roof with multiple different levels and therefore to build the model, there was several different buildings and roof pitches creating a 'wave' sort of effect. For thos reason, there ended up being 45 coverage sections.

The first issue was that we couldn't tie these together on less inverters so the model gave us 45 inverters. However, this doesn't worry me as a more detailed design will be undertaken on site by the electrical designer. However, in order to model the battery storage, I have put in 90kWh capacity (510kWp site) on a site that spill quite heavily to the grid, however this barely charges over the year. I'm guessing its because the battery has to be tied to a singe inverter in the model, which only accounts for 1/45 of the panels. 

Does anyone have a work around for this?
