Is the later maintenance cost high?

Lithium batteries are maintenance-free, requiring only regular cleaning; inverters need routine heat dissipation checks. No extra costs, saving on maintenance over lead-acid batteries/traditional equipment.

Product Q&A

Q:How to choose the model of lithium battery and inverter?

Focus on 3 core aspects: For batteries, check voltage (e.g., 48V) and capacity (e.g., 100Ah); For inverters, ensure input voltage matches the battery, output power exceeds total load by 1.2 times, and waveform is pure sine wave.

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

Lead-acid replacement lithium batteries match lead-acid dimensions and ports for easy replacement without circuit changes; ordinary lithium batteries need device-specific size and interface matching.

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

High-frequency inverters are compact, lightweight, ideal for low-power use like homes and RVs. Low-frequency inverters handle heavy loads, suitable for industrial and high-power motor use.

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

For large items, select special line logistics/full-vehicle delivery. Use wooden box/foam protection to prevent transit damage. Inspect goods upon arrival.

Q:What to do if a fault occurs during use (e.g., inverter error, lithium battery fails to discharge)?

Check manual for common faults (overload, poor contact). If unresolved, contact after-sales for 24-hour response, remote troubleshooting, and repair by mail or on-site within 1-3 days.
