Checked as a single pack, which covers this inverter’s charge current on its own.
Full specifications: LuxPower SNA5000 and Discover AES 42-48-6650.
The four checks
Voltage window: Overlapping window 42 to 57.6 V
The inverter operates from 40 to 60 volts and the battery cuts off outside 42 to 57.6 volts. Both stay inside 42 to 57.6 volts, which covers a normal LiFePO4 charge and discharge cycle with margin at both ends.
Charge current: 120 A into a 130 A limit
The inverter tops out at 120 amps and the battery accepts 130 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Surge rating: Battery surge figure unpublished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 10000 watts draws roughly 208 amps at 48 volts. This battery publishes a 130 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: Both speak CAN, no document names the pair
The inverter and the battery both support CAN. Neither manufacturer publishes a document naming the other unit, and a shared bus standard is not a shared message format. It may well work on the bench. Confirm the protocol setting with both manufacturers before relying on BMS control.
What this means when you install it
Set the inverter charge current to 120 amps or less. That is the inverter maximum, which this bank can absorb. Protect the battery run with a 150 amp Class T fuse and 1 AWG cable.

Questions people actually ask
Will the LuxPower SNA5000 work with the Discover AES 42-48-6650?
Partial match, some fields unverified. Checked as a single pack, which covers this inverter’s charge current on its own. The four checks below show which field produced that result.
What does this pairing cost to wire up?
Beyond the two units, a 150 amp Class T fuse and holder, 1 AWG battery cable cut to matched lengths, and a busbar if you are running 1 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 and the battery both support CAN. Neither manufacturer publishes a document naming the other unit, and a shared bus standard is not a shared message format. It may well work on the bench. Confirm the protocol setting with both manufacturers before relying on BMS control.
What charge current should I set?
The inverter tops out at 120 amps and the battery accepts 130 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
