Q&A
Which types of batteries can it be used with?
It is suitable for common DC batteries such as 12V lead-acid batteries and lithium batteries. Please ensure the battery voltage matches the inverter's input voltage before use.
What capacity battery is needed to meet long-term use?
It needs to be calculated according to the total power of the device, the formula is "Battery Capacity (Ah) = Total Device Power (W) × Usage Time (h) ÷ Input Voltage (12V)". For example, to drive a 1000W device for 5 hours, the required battery capacity = 1000×5÷12≈417Ah, it is recommended to use 2 200Ah batteries in parallel (total capacity 400Ah, actual usage about 4.8 hours).
Can this 2000W inverter power an air conditioner?
If the air conditioner power is within 2000W and the input is AC220V, it can supply power normally. It is recommended to ensure stable power when starting.
Can other input voltages be customized?
Yes, the regular is DC12V, and DC24V, etc. can be customized. Please consult customer service for details.
