So choose the voltage converter, please consider the following information:
1. Inverterparameters:
3000W Inverter, continuous operating power is 1500 W, start功率 (peak power) is 3000 W.
4000W Inverter, continuous operating power is 2000 W, start功率 (peak power) 4000W.
5000W Inverter, continuous operating power is 2500 W, start功率 (peak power) is 5000 W.
6000W Inverter, continuous operating power is 3000 W, start功率 (peak power) 6000W.
8000W Inverter, continuous operating power is 4000 W, start功率 (peak power) is 8000 W.
2. Select the appropriate inverter based on the startup power (peak power) of your devices.
The required start-up power of the devices should be lower than the peak power of the inverter to meet the usage conditions.
If you, for example, purchase a 3000-W converter, it can supply power to devices with a continuous power consumption of up to 1500 W such as computers, TVs, fans, and resistive devices.
Some inductive load devices, however, have a starting power of 3-12 times their continuous power. Even though the continuous power requirement is met, the starting power must also be met to drive the device.
Explain it with an example:
If you use a Noeifevo 12V 100AH battery, can you use a 3000-W converter and a 500-W power supply?
1) Determine first whether the 12-V-100AH battery can support the maximum power of the device:The BMS of the 12-V 100AH Battery is 100A, which supports a continuous discharge current of 100a. This can support a maximum power of 12 V * 100a = 1200 W, which is greater than 500 W.

2) Determine whether the device is resistive or inductive:The Power Drill is an inductive device. (Confirmation that the device is resistive or inductive should be conducted with your supplier so that the starting power can be verified.)

3) Verify that the continuous power requirement is met:The continuous power of the voltage cutoff is 500 W and the continuous power of the 3000-W converter is 1500 W, which is more than 500 W.

4) Verify that the starting performance is met:Die Startleistung des Stromverbots beträgt etwa das Dreifache ihrer kontinuierlichen Leistung (variiert mit verschiedenen Marken). 1500W. Daher kann der 500-W-Stromversorgungsbohrer mit dem Noeifevo 12V 100AH-Akku und dem 3000-W-Wechselrichter verwendet werden.

Note: This method can also be applied to other devices. If you encounter problems or are unsure about the operation, you can consult the customer service. Thanks a lot!

So choose the right battery for the inverter:

Betriebszeit = u (Voltage specified) × I (Battery capacity) × 0,8 × 0,9 ÷ Strom

Example: 12 V 100AH Battery with a 220 V 100W -Lightbulb

Betriebszeit = 12 V x 100ah x 0,8 x 0,9 ÷ 100W = 7,68 Stunden

HINWEIS: 0.8 ist der Batterie-Entladungskoeffizient (konstant) und 0,9 die Wechselrichterumwandlungseffizienz (konstant). Dies ist eine grobe Berechnung und sollte als Referenz genommen werden. Die tatsächliche Verwendung kann variieren; Bitte verlassen Sie sich auf die tatsächlichen Bedingungen.
