3 phase solar system with battery back up

ligwyd

Hi there,

Have a property that is supplied with 208Y/ 120V power.

Goal is to build a solar system for the customer that can sell back to the grid when solar production exceeds local loads and is backed up with battery to run only critical loads if grid goes down.

Just beginning the search for the appropriate equip......

Appreciate any discussion that might get the ball rolling.

Depending on the size/rating of the system, and what the expectations are (need battery back failover or could the customer live with a diesel Genset and, up to, 5 minute genset startup--As an example).

For a larger system, need to get a power engineer with lots of experience involved--Here is a thread where getting the right engineer was able to address (most/all) of the ongoing problems of large 3 phase off grid Genset/inverter system:

Thanks Bill. On a side note, have you ever heard of installing a 240 split phase hybrid inverter with a 3 phase 208Y/ 120V grid power supply present?

Alternatively I guess Fronius (Symo) or Solar Edge has smaller 3 phase inverters (15K ish).......

Appreciate the dialogue.....
