Checked as a bank of 2 packs, which is the smallest number that accepts this inverter’s 120 amp charge current. Fewer packs still run the system, with the charge rate capped in inverter settings.
Full specifications: Sol-Ark 5K and LiTime 48V 200Ah.
The four checks
Voltage window: Overlapping window 42 to 58.4 V
The inverter operates from 42 to 63 volts and the battery cuts off outside 40 to 58.4 volts. Both stay inside 42 to 58.4 volts, which covers a normal LiFePO4 charge and discharge cycle with margin at both ends.
Charge current: 120 A into a 200 A limit
The inverter tops out at 120 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Surge rating: Battery surge figure unpublished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 8000 watts draws roughly 167 amps at 48 volts. This battery publishes a 400 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 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 wired to a busbar rather than daisy chained, so all 2 packs share current evenly.

Questions people actually ask
Will the Sol-Ark 5K work with the LiTime 48V 200Ah?
Partial match, some fields unverified. Checked as a bank of 2 packs, which is the smallest number that accepts this inverter’s 120 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 150 amp Class T fuse and holder, 1 AWG 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 120 amps and the battery accepts 200 amps, so a default install cannot overrun the pack. Adding batteries in parallel raises the accepted current further.
