Can we ship the inverter without batteries and then have them shipped to the site when the system is ready to be installed?

On spec-grade models (FTW2, IPS4, UFT4, 3UFT, NFT) - YES!  …with a caveat.  The system must be invoiced in full at the time of electronics shipment.  We do not split the invoice.  This “locks in” the battery portion of the pricing for 12 months past shipment.

*We ship all “smaller units” complete with batteries only, as they come on one skid or ship via UPS/Fed-ex.  Splitting the batteries out significantly would increase the freight on relatively inexpensive units and is not financially efficient.  This would include:  MICRO, ABC, LPS, CEPS, and LV units.
