Kisae is a relatively new inverter line in the US. They manufacture quality inverters that are elegantly simple and ready to use. I just had this model installed in my motorhome a couple of months ago. It’s a 2000 watt pure sine wave inverter with a 55 amp multi - state charger that was hard wired into my RV’s 120 volt system. An integrated transfer switch is built in allowing you to switch seamlessly from shore power to battery power. It even has a way to remote the LED display for battery status and load measurement.
This inverter/charger is the best thing since sliced bread! It charges the batteries fast and at the proper charge rate, and it’s great having 120 volts to use without the generator running.
The Kisae product line includes Pure Sine wave inverters from 400 watt to 3000 watt, and modified sine wave inverters from 400 watt to 2000 watt.
