The four checks
Voltage window: No usable overlap
The inverter window of 20 to 32 volts and the battery window of 44.8 to 58.4 volts do not overlap usefully. One unit reaches its limit while the other is still in normal operation.
Charge current: 80 A into a 200 A limit
The inverter tops out at 80 amps and the battery accepts 200 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Surge rating: Battery surge figure unpublished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 4800 watts draws roughly 100 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: Both speak RS485, no document names the pair
The inverter and the battery both support RS485. 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 80 amps or less. That is the inverter maximum, which this bank can absorb. Protect the battery run with a 100 amp Class T fuse and 2 AWG cable.

Questions people actually ask
Will the MPP Solar LV2424 work with the EG4 PowerPro WallMount 48V 280Ah?
Specs conflict on at least one field. 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 100 amp Class T fuse and holder, 2 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 RS485. 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 80 amps and the battery accepts 200 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
