645W High Efficiency Lower Lid Double Glass PV Solar Panel with Waterproof Structure

Lead-acid replacement lithium batteries are fully compatible with conventional lead-acid batteries in terms of size and wiring ports, allowing in-situ replacement without circuit modification; ordinary lithium batteries require device matching for size and interface, with a narrow adaptation range.

High-frequency inverters are small in size, lightweight and efficient, suitable for low-power scenarios such as home use and RVs; low-frequency inverters are equipped with transformers, capable of withstanding heavy loads, suitable for industrial and high-power motor load scenarios.

For bulk orders or large items, please choose **special line logistics / full-vehicle delivery**. The manufacturer will provide **wooden box / foam protection** to avoid collision and damage during transportation. You can inspect the goods on the spot upon arrival.

First check the common faults in the manual (such as overload, poor contact). If the problem still cannot be solved, contact after-sales service, which will respond within 24 hours, conduct remote troubleshooting, and arrange for repair by mail or on-site service if necessary, with the fastest resolution within 1-3 days.

Lithium batteries are maintenance-free and only require regular cleaning; inverters only need regular inspection of heat dissipation, with no additional maintenance costs, saving a lot of maintenance expenses compared with lead-acid batteries/traditional equipment.
