Description
- High-Input DC Systems: Converts a matched 60V, 72V, 96V, or 110V DC battery system into split-phase AC power. Select the exact nominal battery voltage; this inverter is not auto-detect.
- 3000W-12000W Power Range: Choose the continuous rating for your combined load and motor-starting demand. Available models cover 3000W, 4000W, 5000W, 6000W, 7000W, 8000W, 9000W, 10000W, and 12000W.
- 120V/240V Split Phase: Pure sine wave output supports compatible North American 120V loads and 240V equipment through multiple outlets and a hardwire terminal.
- Wireless Remote Version: Wireless on/off control works up to 100 ft indoors with walls and doors or 150 ft in open areas. The remote battery is not included; recommend a 23A 12V alkaline battery.
- Protection and Monitoring: Low-voltage alarm and shutdown, over-voltage shutdown, overload, automatic over-temperature shutdown, short-circuit/fuse protection, soft start, cooling fans, and optional RS485 communication.
Standard order configuration: 60Hz output with a US-style Type B socket. Need 50Hz or another socket type? Contact us before ordering so we can confirm availability and the correct configuration.

Frequently Asked Questions
Which battery voltage should I choose?
Choose 60VDC, 72VDC, 96VDC, or 110VDC to match the nominal battery system exactly. The input is not auto-detected.
How do I choose the power rating?
Add running watts for all devices used together and allow extra capacity for motor startup. Available models range from 3000W to 12000W.
What does split-phase output mean?
Split-phase output provides 120V circuits and a 240V circuit from the same inverter when wired according to the product diagram.
What are the standard frequency and outlet?
The standard order is 60Hz output with a US-style Type B socket. Need 50Hz or another socket type? Contact us before ordering.
How far away can I use the wireless remote?
The wireless remote works up to 100 ft indoors with walls and doors, or up to 150 ft in an open area. The remote battery is not included; recommend a 23A 12V alkaline battery.
Why does the panel vary by wattage?
Higher-power models use different outlet, terminal, fan, and enclosure layouts. Check the panel image for the selected model.
Can I connect solar panels directly?
No. Use a regulated high-voltage battery bank or DC bus; a solar charge controller is required between PV panels and the battery.
What protection is included?
The inverter includes low-voltage alarm and shutdown, over-voltage shutdown, overload, over-temperature, short-circuit, fuse, and soft-start protection.
What should I confirm before ordering?
Confirm battery voltage, load and startup demand, AC output voltage, frequency, outlet type, split-phase wiring, and panel layout. Contact us for 50Hz or non-Type-B socket requirements.
