Checked as 4 packs, the most this battery’s published parallel limit allows. Meeting the inverter’s 105 amp charge current would take 5, so the charge rate has to be capped in inverter settings.
Full specifications: Schneider Conext SW 4048 and LiTime 48V 50Ah.
The four checks
Voltage window: Overlapping window 44 to 58.4 V
The inverter operates from 44 to 64 volts and the battery cuts off outside 40 to 58.4 volts. Both stay inside 44 to 58.4 volts, which covers a normal LiFePO4 charge and discharge cycle with margin at both ends.
Charge current: Limit the charger to 100 A
The inverter will deliver up to 105 amps and this battery accepts 100 amps at the bank size shown above, which is already as many packs as the manufacturer’s published parallel limit allows. Cap the charge current at 100 amps in inverter settings. It stays a conflict because a default install pushes past what the BMS permits and the pack protects itself by disconnecting.
Surge rating: Battery surge figure unpublished
A surge to 6800 watts draws roughly 142 amps at 48 volts. This battery publishes a 200 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: Battery publishes no protocol
The inverter speaks Modbus. This battery publishes no communication protocol, so closed loop is not on the table and the pairing runs on voltage limits set by hand. Confirm with the manufacturer that no port exists before assuming it.
What this means when you install it
Set the inverter charge current to 100 amps or less. That is what this bank accepts, below what the inverter would deliver at defaults. Protect the battery run with a 100 amp Class T fuse and 2 AWG cable wired to a busbar rather than daisy chained, so all 4 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: LiTime product pages. Figures here should be read against the revision that covers your serial number, because manufacturers revise specifications without changing the model name.

Questions people actually ask
Will the Schneider Conext SW 4048 work with the LiTime 48V 50Ah?
Specs conflict on at least one field. Checked as 4 packs, the most this battery’s published parallel limit allows. Meeting the inverter’s 105 amp charge current would take 5, so the charge rate has to be 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 100 amp Class T fuse and holder, 2 AWG battery cable cut to matched lengths, and a busbar if you are running 4 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?
The inverter speaks Modbus. This battery publishes no communication protocol, so closed loop is not on the table and the pairing runs on voltage limits set by hand. Confirm with the manufacturer that no port exists before assuming it.
What charge current should I set?
The inverter will deliver up to 105 amps and this battery accepts 100 amps at the bank size shown above, which is already as many packs as the manufacturer’s published parallel limit allows. Cap the charge current at 100 amps in inverter settings. It stays a conflict because a default install pushes past what the BMS permits and the pack protects itself by disconnecting.
