Off-grid 3000W DC to AC True Sine Wave Power Inverter 12V DC to 115V/230V AC, with 12V optional AC transfer switch and/or power saving mode

INT Pure Sine Wave Power Inverter 3000W
INT Pure Sine Wave Power Inverter 3000W

Wenchi's INT-3000W pure sine wave power inverter is a product with hilgy recognition, it can be seen in many larger commercial and non-commercial vehicles, like bus, camping car, truck, etc.


Our 3000Watt True sine wave inverter is carefully designed by our engineers to effetely convert 12Vdc or 24Vdc battery power to 220Vac, 230Vac and 240Vac, optional USB port and/or AC transfer swtich based on modules. We have the ability to customize 3000W for 110Vac output model, feel free to contact us for further information. Standard housing is in square shaped, customize case are also feasible.CE certified. AC transfer switch is optional to switch a load between two sources. Remote control and power saving mode are also optional. Lead-time 60 days. MOQ 50-500PCS. GFCI is optional. Best possible for retailers, distributors, importers, wholesalers, and manufacturers.

Peak (Surge) power is 6000Watt; Efficiency level is 85% to 90%; AC Frequency Output: 50Hz or 60Hz; 2 x AC outlet / VDE Schuko (Optional); Output fully isolation design. Input voltage rating is 10~ 16.5Vdc at full load and room temperature 25°C. Input no load current is 1.0A maximum at 12Vdc.

When the output load is over (105% to 110%), the inverter will shut down to avoid damage (At room temperature 25°C). An alarm buzzer will sound when the input voltage is over 16.5V±1.0Vdc, the inverter will shut down to protect the battery and prevent damage to the plugged device. Battery low alarm will sound at 10.5±0.5Vdc, shutdown at 10.0±0.5Vdc. Green LED on front panel to confirm power on, red LED on front panel to warn of a faulty condition, yellow LED lights up when over temperature occurs. Shutdown will occur when the temperature inside the inverter reaches 60 ± 10℃.

Aluminum alloy case in silver colours with refined surface, the standard colour of housing is in silver, the colour of housing and material is customizable with terms. INT-3000W pure sine wave inverter does not produce electrical noise, and will not damage your applications.

With AC transfer switch model, swtiching a load between AC or DC sources is applicable. AC transfer time<0.1 second.
