I wanna tie 3 220w panels together the voltage on the panels is 29volts so would I need a inverter that is near 660watts and for the voltage it would need to support 87 volts?

For a 12v battery system you will need a 60amp MPPT
For a 24v battery system you will need a 30 amp MPPT
The Ah rating of your batteries should be determined by the expect daily watt hour usage. But a 12volt system should be around 550Ah and the 24volt system around 275Ah. -

The only solar panels that may work need to use micro inverters so they convert the DC from the panel directly to AC.
Most string inverters are sized for a bout 3000 watts.Comment

Unfortunately people still have to go through their POCO to sign a co-generation power contract as well as meet their standards on equipment.
I hope the OP is not just looking to get that 660watts onto the grid without permission.Comment
