Before choosing this inverter

Calculate the combined running wattage of appliances that may operate together and check their start-up surge. Do not size the system from the 3000W peak figure as though it were continuous output. At full continuous load, a 1500W inverter can draw roughly 140A from a 12V system after typical conversion losses, so battery discharge capacity, BMS rating, cabling, fusing and connections must all be suitable.

• Install in a dry, well-ventilated position.
• Keep DC cable runs short and use correctly sized cable and over-current protection.
• Confirm appliance compatibility from the appliance documentation.
• Use a suitably qualified installer for permanent or high-current installations.

Frequently asked questions

Is this a 3000W continuous inverter?

No. The technical specifications list 1500W continuous output and 3000W peak output for less than one second.

Why does continuous output matter?

Continuous output is the power the inverter is designed to supply during normal operation. Peak output is brief surge capacity, commonly relevant when some motors or compressors start.
