An inverter charger does three jobs — make AC from DC, charge the bank from shore/grid, and switch sources — CMX Battery builds them for RV, marine and off-grid where space and simplicity rule.

Overview

An inverter charger combines a pure-sine inverter, a multi-stage battery charger and an automatic transfer switch in one chassis. Shore or generator AC powers the loads and charges the LiFePO4 bank; when that source drops, the unit inverts from the battery and transfers the loads seamlessly. CMX Battery builds inverter chargers matched to 12V/24V/48V LiFePO4 with a lithium charge profile and the AC input your RV, boat or cabin has. They are the right device when you want inverter and charger in one box without a separate hybrid unit.

Typical applications

  • RV and marine: Shore/grid + battery.
  • Off-grid cabins: Generator + bank.
  • Backup: Automatic transfer.
  • Mobile workshops: 12V/24V systems.

How to specify & buying guide

  • Match voltage (12/24/48V) and the lithium charge profile to your bank.
  • Size continuous and surge watts to the loads, especially motor starts.
  • Confirm AC input (shore/generator) voltage and the transfer behaviour.
  • Pair with an LFP-rated BMS for monitoring.

Engineering & manufacturing at CMX Battery

Inverters and charge controllers are matched to the LiFePO4 voltage window and the BMS communication protocol. We validate MPPT tracking, THD, surge handling and the seamless grid/island transition your system design depends on.

Certifications & compliance

  • UN38.3 — Mandatory lithium battery transport test (altitude, thermal, vibration, shock, external short). Required for any cross-border shipment.
  • IEC62109
  • CE — EU declaration of conformity for the applicable directives.
  • RoHS — Restriction of hazardous substances in the battery and BMS.

Frequently asked questions

Inverter or inverter charger?

Inverter charger adds charging and transfer — best for RV/marine/off-grid with a shore or generator source.

Does it charge LiFePO4 correctly?

Yes, with a lithium charge profile; set it before use.

Will it switch to battery automatically?

Yes, the built-in transfer switch handles source loss.

What voltage should I pick?

12V small, 24V mid, 48V once loads pass a few kW.
