Checked as a bank of 2 packs, which is the smallest number that accepts this inverter’s 100 amp charge current. Fewer packs still run the system, with the charge rate capped in inverter settings.
Full specifications: Sol-Ark 30K-3P and Redodo 48V 100Ah.
The four checks
Voltage window: No usable overlap
The inverter window of 150 to 950 volts and the battery window of 40 to 58.4 volts do not overlap usefully. One unit reaches its limit while the other is still in normal operation.
Charge current: 100 A into a 100 A limit
The inverter tops out at 100 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Surge rating: Battery surge figure unpublished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 45000 watts draws roughly 938 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 CAN, RS485. 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 the inverter maximum, which this bank can absorb. Protect the battery run with a 500 amp Class T fuse and two parallel runs of 4/0 cable wired to a busbar rather than daisy chained, so all 2 packs share current evenly.

Questions people actually ask
Will the Sol-Ark 30K-3P work with the Redodo 48V 100Ah?
Specs conflict on at least one field. Checked as a bank of 2 packs, which is the smallest number that accepts this inverter’s 100 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 500 amp Class T fuse and holder, two parallel runs of 4/0 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?
The inverter speaks CAN, RS485. 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 tops out at 100 amps and the battery accepts 100 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
