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 the running watts of the devices used together and allow extra capacity for motor startup. Available models range from 1000W to 5000W.
What output voltage is available?
Select 100V, 110V, or 120V AC, or select 220V, 230V, or 240V AC to match the equipment and region.
What are the standard frequency and outlet?
The standard order is 60Hz output with a US-style Type B socket. Contact us before ordering if 50Hz or another socket type is required.
Does this version include a remote?
This page includes the wireless remote. Range is up to 100 ft indoors or 150 ft in open area; the 23A 12V alkaline battery is not included.
What charging ports are included?
The U5 has dual USB charging ports in addition to its AC outlets. RS485 communication is optional.
Can I connect solar panels directly?
No. Use a regulated battery bank or DC bus; a suitable solar charge controller is required between PV panels and the battery.
What protection is included?
The inverter includes low-voltage, over-voltage, overload, over-temperature, short-circuit, fuse, reverse-polarity, and soft-start protection.
What should I confirm before ordering?
Confirm battery voltage, continuous and startup load, AC output voltage, frequency, socket type, remote preference, and the panel layout for the selected wattage.
