Thinkstar 4000W Pure Sine Inverter Charger 24V 120V 50A

SKU CH-FBXC-1MY9E

Delivers 4000 W continuous pure-sine output with 12000 W surge for 20 seconds, charges at 50 A, and transfers in 10 ms

  • 4000 W continuous pure-sine output powers sensitive loads cleanly
  • 12000 W surge for 20 seconds handles heavy motor starts
  • 50 A multi-stage smart charger restores LiFePO4, GEL, AGM and lead batteries
  • 10 ms typical transfer time keeps equipment running during grid loss
  • Marine-coated construction protects internals in harsh environments

Product Identity

The Thinkstar 4000W Pure Sine Inverter Charger converts 24 V DC battery power into 120 V AC output. It delivers 4000 watts continuous power with a 12000 watt surge capability for 20 seconds. A built-in multi-stage smart charger provides up to 50 amps of charging current for lithium LiFePO4, GEL, AGM and lead-acid batteries. The unit features marine-coated protection and a terminal block for secure connections.

Ideal Use Cases

This inverter suits off-grid installations, marine vessels and backup systems that require pure sine wave output at 50 Hz or 60 Hz with low distortion. The 10 ms typical transfer time supports uninterrupted operation for sensitive electronics. Buyers who need a higher continuous power rating or a different DC input voltage should look elsewhere.

Decisive Specification

The 24 V DC input requirement is the single specification that determines compatibility. Your battery bank must be configured for 24 volts nominal to operate this inverter charger correctly.

Questions about this item

What DC voltage and AC output does this inverter require?

The unit runs from a 24 V DC battery bank and delivers 120 V AC at 50 Hz or 60 Hz.

How do I connect the battery and AC wiring, and what step is often missed?

Use the terminal block for DC cables and the AC terminals for load wiring; the step often missed is setting the Battery Priority Selector to match your battery chemistry.

What battery types can the built-in charger maintain, and what should I verify?

The 50 A multi-stage charger supports LiFePO4, GEL, AGM and lead-acid; verify each battery's own charging specifications before use.
