Hi all, I have a Smart Solar 75/15. It was delivered with a jumper connected across what I think is the Tx Rx lines of the VE Direct port. I would like to add a lorawan transmitter. Is it ok to remove this jumper? Presumably I will have to to connect the transmitter?
Also, does anyone know if the lorawan transmitter is waterproof? Or, can the whole unit, including antenna be mounted indoors, i.e. within a shed?
Many thanks!
Yes you can remove it.
Once removed the VE.direct port will default to a Communications port.
I assume you are NOT using the Load Output screw terminals on the MPPT to power a load?
If you are using the Load Output then please be aware that removing this jumper disables the "Battery Life" algorithm which helps manage your battery life by cutting off loads until the battery has reached a healthy State of Charge.
Without out this you will need some type of protection via BMV or Battery Protect or your own custom solution to help save your battery from being discharged to zero by loads.
You can set the load output via the App as well if you are using the Load Output terminals.
It is just important to remember to set it !
If you power loads directly from the battery then you need some form of additional battery protection to avoid discharges to zero.
You can still you use the Battery Life algo if you are using the VE.direct port for communication, but you have to manually set the Output to use the Battery Life algo in the app.
