grid-tied retrofit with battery storage -FIT meter

[javiermi]

Hi

I have recentlly bought a Sofar Solar ME3000SP battery storage inverter and I'm not sure where I should I connect the unit

I currently have a grid-tied inverter fitted with a FIT "production" meter, so I'm getting paid for the energy I produce ( independently if I use the energy or not), so I don't want to loose that money

All schematics I have seen show the new unit connected to the AC output of the old inverter, but If I do that, my ME3000SP unit will reduce the production energy as it saves some power to the batteries

So the question is: have any of you guys have a ME3000SP unit while at the same time getting paid a FIT tariff?. If so, where did  power up the unit: before or after the FIT meter?

 

Thanks

Connect it AFTER the generation meter.

 

BUT check the fine print of a FIT contract to see if this is allowed or not first.

You will need the permission of the FiT administrator to connect it, and if you are being paid an export tariff (non-deemed) you would additional need to satisfy the administrator that there will be no export from the battery to the grid.  IMHO.

PS. I have PV plus separate storage for the grid (and other off-grid): https://www.earth.org.uk/img/PV/Enphase-Energy-Storage-Diagram.pdf

Which would also negate the whole reason for fitting batteries.

Not at all.  Carrying internal loads to avoid/reduce imports from the grid is what mine do, ie increase self-consumption.
