Product Q&A

Q:What's the difference between lead-acid replacement lithium batteries and ordinary lithium batteries?

Lead-acid replacement lithium batteries match conventional lead-acid batteries in size and wiring, allowing easy replacement without circuit changes; ordinary lithium batteries need device matching for size and interface, with limited adaptation.

Q:How to choose between a high-frequency inverter and a low-frequency inverter?

High-frequency inverters are compact, lightweight, and efficient, ideal for low-power use like homes and RVs; low-frequency inverters with transformers handle heavy loads, suited for industrial and high-power motor scenarios.

Q:How to transport large-sized equipment (such as high-power inverters and rack-mounted batteries)?

For bulk orders or large items, opt for special line logistics/full-vehicle delivery. The manufacturer provides wooden box/foam protection to prevent damage. Inspect goods upon arrival.

Q:What should I do if a fault occurs during use (like inverter error, lithium battery failure)?

Check common faults in the manual (like overload, poor contact). If unresolved, contact after-sales service for 24-hour response, remote troubleshooting, or repair by mail/on-site, resolved in 1-3 days.

Q:Is the later maintenance cost high?

Lithium batteries are maintenance-free, needing only regular cleaning. Inverters require heat dissipation checks, with no extra maintenance, saving costs over lead-acid batteries/traditional equipment.
