1000W Pure Sine Wave Inverter with Transfer Switch.
Our price is the manufacturer's home-market RRP — what this gear sells for where it's made. Branded marine equipment in Thailand typically retails 15–90% above that, when prices are published at all. Ours doesn't.
Converts 12 V battery power to 230 V / 50 Hz AC power — this is the international “i” version for Thailand, Asia and Europe, not the 120 V North American model. Ideal for running tools and appliances flawlessly while away in your car, truck, boat or RV; and for ensuring motor loads run at optimal efficiency at your remote home or cabin.

The SWXFR1210 gives 1,000 W continuous with a 2,000 W surge for motors starting. Add up what runs at the same time and keep it under the continuous figure; the KISAE applications chart in Downloads lists more appliances.
At full load the SWXFR1210 draws about 94 A from a 12 V bank, so plan about 120 Ah of Fullriver AGM for every hour at full power (within Fullriver's 80% depth of discharge). KISAE's manual asks for AWG 2 (34 mm²) DC cable, at most 1.5 m long, with a 150 A fuse or breaker at the battery.
The SWXFR1210 inverter and owner's manual. DC cable, fuse and lugs are not included.
Yes. The inverter runs from any 12 V bank; its low-voltage shutdown is at 10.5 V, so set the battery's own protection above that.
For 2,000 W and above, 24 V halves the current, so cables, fuses and losses are smaller. We stock both.
This model is a special order: we bring it in for you and confirm the lead time before you pay.
It carries KISAE's manufacturer's warranty, and we handle any claim for you in Thailand. Special-order items are brought in for you, so they are covered for faults rather than change of mind. Full details on the returns page.
