SolaX X3 RetroFit AC Coupled Battery 3ph Inverter 10kW (Pack of 5)
SolaX X3-FIT bulk pack — Five AC-coupled retrofit inverters — for a programme of battery retrofits.
An AC-coupled retrofit inverter is the tool for adding storage to a property that already generates. It sits beside the existing PV system rather than between the array and the grid, so the original installation is left alone.

About the SolaX X3-FIT bulk pack
That makes it the natural product for a retrofit programme, and a pack of five is how a programme is bought.
The X3-FIT is three phase at 10 kW. It has no PV input of its own — it charges from the property's AC side and discharges back to it.
The pack is not split. Check the quantity against the programme before ordering.
What is in this package and what it needs
This is five X3-FIT AC-coupled retrofit inverters on one part number.
The same X3-FIT G4 10 kW AC-coupled retrofit inverter as the single listing, in a pack of five. It is AC-coupled, so it adds a battery to a property that already has PV without touching the array.
