Inverter Chargers for Caravan, Marine and Off-Grid Power

An inverter charger combines a pure sine wave inverter, a battery charger and an automatic transfer switch in one unit. On battery power, it converts 12V, 24V or 48V DC into 240V AC to run appliances. When shore power or a generator is connected, it passes AC through to your loads and recharges the battery bank. This range covers caravans, RVs, boats, trucks, tiny homes and off-grid or commercial installations.

Victron and Enerdrive Inverter Charger Ranges

Most of this collection is Victron. Victron model names follow a simple code. For example, 12/3000/120-50 means a 12V battery system, 3000VA inverter output, 120A charge current and a 50A AC transfer rating. The ranges include:

• Victron MultiPlus and MultiPlus Compact: 500VA to 3000VA units for caravans, campervans and boats. Models also cover larger 5000VA and 20000VA systems.
• Victron MultiPlus-II: 3000VA to 15000VA models, with GX versions that include built-in system monitoring.
• Victron Quattro and Quattro-II: Two AC inputs, so the unit can manage both shore power and a generator. Sizes run up to 15000VA.
• Victron EasyPlus, EasySolar and EasySolar-II GX: All-in-one packages. EasySolar models include an integrated MPPT solar charge controller.
• Victron Multi RS and Multi RS Solar: 48V 6000VA units for residential and off-grid energy storage.
• Victron Multi HS19: A 15kW high-voltage solar inverter charger for commercial and industrial battery systems.
• Enerdrive 12V inverter chargers: 2000W/80A and 3000W/100A models for caravan and 4WD touring setups.

If you want solar charging built into the same unit, compare the dedicated inverter/charger/MPPT range.

Why Choose an Inverter Charger Over Separate Units

A combined unit reduces wiring, saves mounting space and handles switching between battery and external AC automatically. Many Victron models offer PowerAssist, which uses battery power to support a limited shore or generator supply during high-demand periods. Charging profiles can be configured for lithium (LiFePO4), AGM and flooded batteries, which helps protect battery life in mixed or upgraded systems.

Sizing and Selection Tips

• Match battery voltage: 12V suits most caravans and 4WDs. 24V is common in trucks and larger boats. 48V suits homes, tiny homes and high-power systems.
• Size the inverter output: Add up the appliances you will run at the same time, then allow headroom for start-up surges from loads such as air conditioners and microwaves.
• Check the charge current: Keep the charge rate within your battery manufacturer's recommended limits.
• Consider AC inputs: Choose a Quattro if you need both generator and shore power connections.
