Good Afternoon, is it possible to input your own charging scenario for battery systems? for example we intend to charge our batteries at night approximately during the hours of 1am and 4am (we purchase the energy from Grid cheaper during that window) so we would like to see charging data based on charging from Grid and just topping up the batteries from PV during the day when PV available. regards

Thanks appreciated

Martin please find attached, when I select location data for Stoke on Trent there are 4 options each with differing Yields. 14d - STO3455064206.pvprj

Martin, we noticed an improved Specific Yield for an area as per attached, yet this was not visible in R4, I only as as we obviously want the best design output for an area and if this is an improvement in background modelling in the software we will apply to all of our designs for this area.

we have noticed a significant specific yield improvement between R4 and R5 2019 premium, is there an improved climate data model deployed as part of the release?

Martin, many thanks for the information, I will have a good read up and decide form there. kind regards

Suggested best Model to apply for UK Based projects in reference to below: Model for Diffused Irradiation - Model for Irradiation on the Incline Plane - Im aware that the norm is to use Hoffman / Hayes and Davies but is this best option?
