Connect the LoRa module.

When the panel output voltage is 3.7-4.2V, refer to the connection method for LoRa modules. Please note other LoRa modules, ensure the positive and negative poles of the power supply are correct, and adjust the positive and negative wires accordingly.

LED

Equipped with indicators for charging, battery level and power output for easy battery status monitoring. Adopting a cyclic operation design, it maintains constant unattended cycling regardless of the battery's charge level, with absolutely no manual intervention required.

VSWR test

Our antennas adopt copper tube design, which delivers far better signal reception than the PCB antennas used by other suppliers. Every single antenna undergoes a VSWR test to ensure consistency in signal receiving and transmitting performance.

PV panel QC inspection

We inspect the PV panels with an EL camera to ensure every product delivered to you is qualified. Any defective PV panels will be scrapped directly.

Low-power Charging Control Board

We have optimized the power consumption of the charging control board and minimized its internal power loss.

IP66

Note: After installing the battery, ensure the waterproof silicone gasket is properly seated—it is critical for sealing. Tighten the screws to apply a certain amount of pressure to the silicone gasket, ensuring its waterproof function. Meanwhile, use the screw waterproof silicone plugs from the accessory bag to seal all 8 screw holes.
