An inverter charger does three jobs — make AC from DC, charge the bank from shore/grid, and switch sources — EGbatt 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. EGbatt 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 EGbatt

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.
