Checked as a bank of 2 packs, which is the smallest number that accepts this inverter’s 140 amp charge current. Fewer packs still run the system, with the charge rate capped in inverter settings.
Full specifications: Schneider XW Pro 6848 and Discover AES 48-6650.
The four checks
Voltage window: Overlapping window 44 to 57.6 V
The inverter operates from 44 to 64 volts and the battery cuts off outside 42 to 57.6 volts. Both stay inside 44 to 57.6 volts, which covers a normal LiFePO4 charge and discharge cycle with margin at both ends.
Charge current: 140 A into a 260 A limit
The inverter tops out at 140 amps and the battery accepts 260 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
Surge rating: Battery surge figure unpublished
A surge to 12000 watts draws roughly 250 amps at 48 volts. This battery publishes a 260 amp continuous rating and no separate surge figure, and continuous is the wrong number to check a motor start against. Confirm the peak rating and its duration with the manufacturer before running motor loads.
Closed-loop communication: Named in a manufacturer document
A manufacturer document names this exact pairing for closed-loop operation over CAN, Modbus. That is the only evidence this site accepts for a match on this check. Select the matching protocol profile in the inverter menu during commissioning.
What this means when you install it
Set the inverter charge current to 140 amps or less. That is the inverter maximum, which this bank can absorb. Protect the battery run with a 200 amp Class T fuse and 2/0 AWG cable wired to a busbar rather than daisy chained, so all 2 packs share current evenly.

Manufacturer documents
Schneider has no public document library this site has been able to verify. Every figure on this page therefore needs checking against the paperwork that shipped with your unit.
Manufacturer documents: Discover Battery documentation. Figures here should be read against the revision that covers your serial number, because manufacturers revise specifications without changing the model name.
Both units, current pricing
Prices on these move week to week, and the battery is usually the line item worth watching.

Questions people actually ask
Will the Schneider XW Pro 6848 work with the Discover AES 48-6650?
Partial match, some fields unverified. Checked as a bank of 2 packs, which is the smallest number that accepts this inverter’s 140 amp charge current. Fewer packs still run the system, with the charge rate capped in inverter settings. The four checks below show which field produced that result.
What does this pairing cost to wire up?
Beyond the two units, a 200 amp Class T fuse and holder, 2/0 AWG battery cable cut to matched lengths, and a busbar if you are running 2 packs. A comms cable if you intend to attempt closed loop, and the pinout is rarely the same between brands.
Where does this pairing go wrong in practice?
A manufacturer document names this exact pairing for closed-loop operation over CAN, Modbus. That is the only evidence this site accepts for a match on this check. Select the matching protocol profile in the inverter menu during commissioning.
What charge current should I set?
The inverter tops out at 140 amps and the battery accepts 260 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
