I’m considering purchasing a HT-M02 gateway, however, I’m a little concerned about how to power the system. In the technical spec section of the product description page (https://heltec.org/project/ht-m02/) it is stated that the device can run off 220v/110v or PoE at 51v. However, it is inferred that the 4G variant does not come with PoE.
The company I work for plan to deploy a gateway in a remote location, using batteries and a solar panel to provide power - utilising the 4G/3G network to sending data to chirpstack or TTN.
How would we go about powering the device? Am I correct to assume PoE is not available with the 4G variant?
It seems like poor practice to have to use a DC-AC step-up converter on the battery. Is this my only option?
Thanks in advance!
