480W A Grade Bifacial Solar Panel Double Glass IP68 Junction Box Included

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.

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.

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.

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

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.
