Checked as a single pack, which covers this inverter’s charge current on its own.
Full specifications: Victron MultiPlus-II 48/5000 and Freedom Won eTower 5.
The four checks
Voltage window: Overlapping window 44 to 57.6 V
The inverter operates from 38 to 66 volts and the battery cuts off outside 44 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: 70 A into a 100 A limit
The inverter tops out at 70 amps and the battery accepts 100 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Surge rating: Battery surge figure unpublished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 9000 watts draws roughly 188 amps at 48 volts. This battery publishes a 100 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. 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 70 amps or less. That is the inverter maximum, which this bank can absorb. Protect the battery run with a 125 amp Class T fuse and 2 AWG cable.

Questions people actually ask
Will the Victron MultiPlus-II 48/5000 work with the Freedom Won eTower 5?
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 125 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?
A manufacturer document names this exact pairing for closed-loop operation over CAN. 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 70 amps and the battery accepts 100 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
