i had a question please, i am working on a project about sizing PV system grid-tied , in my project i have to design the system the way that the inverter should shutdown the PV modules when there is a excess of electricity , because in our country it s not allowed to sell the surplus to the grid. at the same time, in bad conditions of the PV system, we need to take electricity from the grid. HELP. plz!

Some questions, dose the grid utility allow grid tied but will not pay back if injected? Or do they not allow injection?
Regarding the grid, is it stable? or are there frequent outage?, battery backup can be useful if this is the case.
Do you have peak billing, when the price is higher during certain hours, or is it a flat rate 24 hours, again batteries could be used to offset peak billing.
