The polycrystalline solar panel has 18% high conversation efficiency. It works on 18volt operation voltage and outputs a total of 40watt DC power. It’s designed for connecting directly to the EZR53 solar-battery powered 4G router.
Due to expensive freight, suggest buying a similar grade solar panel from the local market.
The solar panel should not directly connect to outdoor or indoor routers. It needs a solar power controller to protect against overvoltage.
Solar Operating Voltage
The solar panel operating voltage should within the power range on the solar power controller. Suggest using 12~18volt solar panel on EZR53 router.
Solar Output Power
The bigger solar panel has bigger output power. To recharge internal battery pack in EZR53 router, suggest using solar panel with 40~80watt output power.
Monocrystalline is more efficient than a polycrystalline solar panel. If the sunshine is not sufficient, you should choose the monocrystalline solar panel.
High Conversion Efficiency
The solar panels have different conversation efficiency. Please select the higher efficiency. Suggest using a solar panel with ≥ 16% conversation efficiency.
