1. Pure sine wave inverters + one more design (fast action AC synchronized transfer switch). When AC is normal, inverter delivers power by AC directly. Once it detects AC failure, it delivers power by DC battery automatically.
2. Microprocessor based design.
3. Green power function.
4. Remote control interface.
5. Heat sink built in internal.
1. Soft start. 2. AVR design. 3. Input & output isolated. 4. Auto temperature control fan. 5. Reverse polarity protection. / by fuse / diodes. 6. Output short circuit protection. 7. Temperature protection: 50 +/- 5degrees. 8. Overload protection. 9. Input low voltage protection. 10. Input high voltage protection. 11. Low battery alarm. 12. Low battery shutdown.
