I would be very grateful for some feedback for a query I have to optimally configure my solar panel with battery back-up system.
I have a 5kw Growatt inverter, a 5kw lithium ion battery and a 2.7kw solar panels.
I am still connected to the grid.
My idea is to have the following:
1. Let the battery discharge to 50%
2. Let the sun charge it to 100%
3. Discharge the battery to 50% overnight
4. Maintain the battery charge at 50% until the sun charges it to 100%
Is it possible to keep the battery in a state of 50% charge whilst the house is powered overnight through the grid?
Your feeback will be highly appreciated.
Thanks!!!
