Configuration on Losses

[Johnny]

Hello everyone. I'd have hard times using this software since I am new. I am designing a hybrid system with battery. I'd like to ask if how to properly design my system since I have only a daily demand of 313kWh and my PV system panel that is to be yield is 333kW per day. However, as I simulate my system for a year it has a lot of energy excess that is to be sent on the grid which is not ideal since my goal is that the PV should utilize the energy and the minimal excess must be on battery or to sale on grid.

Dear Johnny,

First of all, in a self-consumption + storage system, the system responds to the user's load. So, if you have a small load profile and a large PV system, excess energy will be injected into the grid.

Since I don’t know your exact goal, I suggest creating multiple variants — starting with fewer PV modules, then trying with higher storage capacity. This will give you different results and help you find the best configuration.
