New Product: SolarMAX LiPo Solar Power System

SolarMAX LiPo and Data Gathering System for SkyWeather / Raspberry Pi / Arduino is a SwitchDoc Labs designed system to charge LiPo batteries from Large 12V Solar panels in order to provide more power to small computer systems.   SolarMAX is designed to collect and return data about the solar panel system to the powered (or other) computer via a LoRa link.  SolarMAX collects and transmits the following data via 433MHz LoRa Radio every 30 seconds.  No data cable needed!  It transmits:

• LiPo Battery Voltage
• LiPo Battery Current
• Solar Panel Voltage
• Solar Panel Current
• Load Voltage
• Load Current

It also supplies the following about inside the SolarMAX box:

• Inbox Temperature
• Inbox Humidity

You can buy the SolarMAX LiPo system here.

SolarMAX uses a 433MHz LoRa module which can transmit up to 2 kilometers or further with larger antennas and uses very little power.

This is a perfect system for powering SkyWeather and other small computer systems.
