Marstepower 720W Solar Panel System - Flexible Design for Homes

For lithium 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 pure sine wave is suitable for most appliances.

Lead-acid replacement lithium batteries fit conventional lead-acid sizes and ports for easy swap; ordinary lithium batteries require matching size and interface, with limited adaptability.

High-frequency inverters are compact, lightweight, efficient, and suit low-power uses like homes and RVs; low-frequency inverters have transformers for heavy loads, ideal for industrial use.

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.

Check manual for common faults (e.g., overload, poor contact). If unresolved, contact after-sales service. They respond within 24 hours for remote troubleshooting and arrange repair by mail or on-site if needed, resolving in 1-3 days.
