Kisae is Canadian company run by former Xantrex employees with offices in Canada and a factory in China. They specialize in small, high quality sine wave inverters, and we have tested their 400w inverter under very harsh conditions here in Arizona. They perform very well and offer a lot of value for money. Kisae is a lean company that is able to offer very competitive pricing . We are stocking their 400w, 1,000w and 2,000w true sine wave inverters in 12v battery voltage. These are true continuous power ratings, unlike some competitors that over-rate their power production. Kisae will soon introduce 24v models as well.
