Solar Weather Station Power System
A guide to sizing solar panel, RS485 MPPT controller, LiFePO4 battery and outdoor protection for remote weather station and monitoring equipment.
Best fit
Use this page when the main project risk is not the sensor itself, but keeping the weather station, gateway and communication module powered reliably outdoors.
Start from the load budget
Power design starts with the average and peak load of sensors, gateway, communication module and any heater or auxiliary device. Reporting interval and sleep mode behavior affect the real daily energy requirement.
MPPT and battery selection
An RS485 MPPT controller can expose charging voltage, current, battery status and fault data to the monitoring gateway. LiFePO4 batteries are commonly selected for cycle life and stability in outdoor monitoring applications.
Outdoor protection
The power system should consider IP-rated enclosure, ventilation, cable glands, fuse protection, surge protection, mounting angle, theft prevention and maintenance access.

FAQ
How many autonomy days should be planned?
It depends on local weather, service expectations and site criticality. Buyers should share load data, reporting interval and required backup days for sizing.
Why use an RS485 MPPT controller?
RS485 allows the gateway to read charging status, battery voltage, current and faults, so power health can be monitored remotely.
Can this power system be bundled with sensors and gateway?
Yes. SunGene can specify power accessories together with weather sensors, outdoor enclosure, gateway and dashboard requirements.
