Power Inverters

Inverter size depends on simultaneous AC load requirements:

• List all AC devices that may run simultaneously
• Note wattage of each device
• Sum continuous wattages for sustained operation
• Add 25–50% safety margin for inrush current peaks

Typical load requirements:

• Boats and RVs: 1,500–2,500W

Merlin Power recommends KISAE or Merlin Extreme Duty Inverters.

An inverter converts direct current (DC) battery power to alternating current (AC) electricity. The process:

• DC input from 12V, 24V, or 48V batteries enters the inverter
• Internal electronic conversion creates an AC waveform simulating household mains power
• Pure sine wave inverters produce smooth, sinusoidal AC matching mains quality ensuring any onboard AC appliance will work without exception.

Merlin Power stocks pure sine wave inverters ensuring compatibility with modern appliances, LED drivers, and control electronics. All include integrated low-voltage shutdown, high-temperature shutdown, and remote monitoring.

The best inverter is a pure sine wave unit matching your power requirements, voltage, and application. All inverts in our product catalogue are pure sinewave. Merlin Power recommends:

• KISAE Technology Inverters – reliable, simple-to-use inverters with high surge capacity, clean output and built-in low battery, overload, overheat, and short-circuit protection. 
• Extreme Duty Inverters –  designed specifically for mission critical applications where lives and livelihoods depend on power. They hold an automotive e-mark which ensures legal fitting aboard road-going vehicles.
• KISAE Auto Changeover Inverters - If you wish to fit an inverter and also have shorepower, a method of selecting between them must be fitted. This can be a manual switch or remote transfer relay. Merlin Auto Changeover Inverters already have the transfer relay built in. Key specifications: continuous rating (watts), peak rating (inrush current), 90%+ efficiency, pure sine wave, input voltage matching your system, remote control.

Merlin Power sizes inverters for your appliance loads and selects optimal models for reliability, efficiency, and integrated system compatibility.

Yes, inverters are essential for solar-powered systems. The process:

• Solar panels generate DC power during daylight
• Charge controller regulates power into batteries
• Inverter converts battery power to AC for appliances
• At night, inverter draws from batteries
• During day, excess solar charges batteries
• Modern systems include MPPT (Maximum Power Point Tracking) chargers optimising solar capture

Merlin Power designs systems combining solar panels, MPPT chargers, Fullriver batteries, and KISAE/Sine inverters as cohesive units. Pure sine wave inverters are essential for reliable solar system operation.
