AE Remote PV Tie (RPT )
Accessory
™
Field-proven accessory that lowers
home run conductor costs for
commercial and utility-scale projects
The greater the distance between the array and inverters,
the higher the project cost and the higher the DC cable losses.
You can reduce the levelized cost of energy (LCOE) with an
Advanced Energy Remote PV Tie (RPT) by connecting the
neutrals of the arrays in the field and eliminating expensive,
long length and large diameter wires of the neutral DC home
run legs and required conduit. The positive and negative hot
wires connect the arrays to the AE inverter and the RPT puts
the neutrals in series at the array. When installed with AE
NX inverters, the RPT accessory reduces the distance of DC
transmission current over conventional 600 VDC
The AE RPT is backed with a complete 5-year warranty coverage
ensuring there are no surprises during the warranty period. Plus,
you have the peace of mind of being backed by AE's legendary
service and support.

array will cut DC losses. This enables the inverter to be placed
in a position to reduce the AC wiring losses. The result is a
higher total system efficiency that can create an opportunity
to use fewer modules in your system.
The robust, stainless steel, outdoor-ready design is used in a
variety of environments from the high desert mountains to the
Pacific tropics and reliably runs day in and day out with NEMA
3R construction.

With the AE RPT™ accessory, you reduce BoS material costs and increase
the potential for higher plant efficiency.
