Protect sensitive AC loads with a pure sine wave inverter.

When it comes to microwaves, laptops and other sensitive equipment a pure sine wave inverter is the best way to ensure performance and prevent damage. Kisae True Sine Wave inverters are engineered to silently supply AC power with minimal harmonic distortion from your battery banks. This grid quality power protects and extends the life of sensitive electronics by allowing them to operate and function as designed.

This pure sine wave inverter is easy to use. Two standard three-prong 120V GFCI outlets are built into the front of the inverter for ‘plug and play’ operation. An integrated 5V USB port is offered to charge mobile devices without having to give up one of the outlets. Vital system information is provided through a bright LED display that shows input voltage, output power, fault warning and error codes. LED indicators display system status.

Kisae inverters have built in safety features to protect the inverter and the boat’s electrical system. To prevent battery damage, a low-voltage shut-down will turn OFF the inverter if batteries dip to 10.5V; an alarm will sound to provide time to save your work (if on a computer) before AC is cut off. Overvoltage protection shuts down the inverter at 15.5V. In extreme temperatures, the inverter will also shut down to prevent damage.

The 400W continuous rating makes this inverter ideal for boats with minimal AC demands or as a dedicated inverter to electronics. Great for running a flat screen TV, entertainment equipment or blender individually--not at the same time. The 800W surge capacity will allow spikes caused during start-up of AC loads without blowing a fuse or tripping a breaker.

Continue to enjoy the convenience of using electronics, appliances and laptops when you are away from the dock by converting DC battery power to a safe AC power that is compatible with any load. Install a Kisae True Sine inverter and get more out of your house bank batteries.
