Answers Buyers and AI Search Ask
Can a ZENTROVOLT inverter run an air conditioner?
Yes. Our 3000W and larger models handle the high starting surge of RV and small room air conditioners. For a 9000 BTU AC we recommend a minimum 3000W low frequency inverter, which delivers up to 300% surge for 20 seconds.
Can I use lithium batteries (LiFePO4) with your inverters?
All ZENTROVOLT inverter/chargers are lithium-compatible. Adjustable charge profiles support LiFePO4, AGM, gel and flooded batteries. The BMS communication port is optional on OEM orders.
What is the difference between pure sine wave and modified sine wave?
Pure sine wave output matches utility grid power (THD < 3%), running sensitive electronics, motors and medical equipment safely and quietly. Modified sine wave is cheaper but causes buzzing, heat and can damage compressors and audio gear.
What cable size do I need for a 3000W inverter?
For a 12V 3000W inverter use 4/0 AWG (95mm²) cables under 1.5m. For 24V systems use 2/0 AWG (70mm²). Always install a DC fuse or breaker within 15cm of the battery.
Can I connect solar panels directly to the inverter?
Our hybrid inverter/charger models include a built-in MPPT solar charge controller (up to 145V/5000W PV input). Standalone inverters require a separate charge controller between panels and battery.
Do you offer OEM / ODM and custom labeling?
Yes. We provide full OEM and ODM services including custom branding, housing color, packaging, firmware, output voltage (100–240V), plug type and certification support (CE, ETL, SAA, PSE).
What is your lead time and MOQ?
Stock models ship in 7–10 days. OEM/ODM orders typically take 25–35 days. Custom branding is available, with MOQs varying by model.
What warranty do you offer?
Standard warranty is 12 months. All units undergo 100% full-load aging tests before shipment.
