Will it run my appliances?
| Laptop charger | about 65 W |
| Compressor fridge | 40–100 W running, 5× to start |
| Fan, TV, lights, router | 10–60 W each |
| Coffee machine | about 1,200 W |
| Microwave | about 1,000 W |
| Induction hob | 1,800–2,000 W on full |
The SW1204 gives 400 W continuous with a 800 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.
Battery and cable
At full load the SW1204 draws about 37 A from a 12 V bank, so plan about 50 Ah of Fullriver AGM for every hour at full power (within Fullriver's 80% depth of discharge). Keep the DC run short and fuse it at the battery; tell us the run length on LINE and we will size the cable and fuse with you.
In the box
The SW1204 inverter and owner's manual. DC cable, fuse and lugs are not included.
Questions
Does it work with lithium (LiFePO4) batteries?
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.
12 V or 24 V?
For 2,000 W and above, 24 V halves the current, so cables, fuses and losses are smaller. We stock both.
Is it in stock?
This model is a special order: we bring it in for you and confirm the lead time before you pay.
Warranty and returns
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.
