Convert Power Efficiently

A power inverter converts DC battery power into AC power, allowing you to run standard electrical appliances from battery systems.

An inverter charger combines a power inverter and battery charger in one unit, allowing seamless switching between battery power and external AC sources.

Power inverter chargers reduce system complexity, save space and improve efficiency by integrating charging and inversion into a single device.

A DC to DC battery converter manages charging between different battery banks, ensuring safe and efficient power transfer.

Yes. Merlin Power’s power conversion products are designed for marine, campervan, vehicle and off-grid environments where reliability is critical.

The best battery charger matches your battery type, voltage, and charging requirements. Smart multi-stage chargers with temperature compensation deliver optimal charging without damage. Merlin Power stocks premium options:
KISAE Technology multi-output chargers – adaptive charging for multiple battery banks with different chemistries.
TBS Omnicharge heavy duty industrial battery chargers – extreme duty with 8-stage smart charging and universal AC input
All models use adaptive charging to ensure batteries receive the correct charge at all times to ensure the battery condition is never compromised. Select chargers are built with an integrated MPPT (Maximum Power Point Tracking) and are often the preferred option for solar integration.

To choose a battery charger:
Identify your battery type (AGM, Flooded, Lithium, etc.) and voltage (12V, 24V, 48V)
Determine input power sources available (AC mains, alternator, solar)
Calculate required charge current based on battery capacity and desired charge time
Consider smart features – temperature compensation, multi-chemistry support, remote monitoring
Evaluate space constraints and mounting location
Assess redundancy needs – multiple chargers for critical systems
Check compatibility with your battery management system (BMS)
Choosing the wrong size charger can cause undercharging or overcharging, leading to reduced battery life and unnecessary expense. Contact Merlin Power's technical team for a customised specification.

Quality battery chargers typically last 10+ years with correct operation. Merlin's premium brands (KISAE, TBS) are engineered for extended service life in demanding environments. Lifespan depends on:
Component quality and low DC ripple design
Operating temperature and proper ventilation
Electrical load and input power quality
Regular maintenance and adequate cooling
Proper installation with appropriate fusing and cabling maximises charger longevity. All Merlin Power battery chargers are covered by a market-leading 5 year warranty.

Smart battery chargers provide critical advantages:
Smart multi-stage charging protects batteries and extends lifespan
Temperature compensation prevents extreme weather charging damage
Integrated safety features include reverse-polarity protection and thermal shutdown
Simultaneous multi-input operation charges from multiple sources automatically
Minimal maintenance required compared to manual charging
High efficiency reduces energy waste and operating costs
Low DC ripple output protects sensitive electronics and extends battery life
Seamless integration with PowerBank battery management systems ensures safe operation

Inverter size depends on AC load requirements; charger size depends on the size of the battery bank you are installing this with. For combined units:
Inverter wattage – sum simultaneous AC devices plus 25% safety margin; typically 2,000–5,000W
Charger amperage – this must match or exceed the recommended charge rate of your battery bank

Inverter chargers combine three functions:
Inverter mode – converts DC battery power to AC electricity
Charger mode – converts AC mains power back to DC for battery charging
Pass-through mode – AC mains power provides AC output
The unit automatically switches modes:
When 240V mains available, charger charges batteries with intelligent multi-stage charging and provides AC output to circuits
When mains disconnects, inverter seamlessly supplies AC power from batteries
Integrated control monitors battery voltage, temperature, input power quality, and output load.
