If the system is connected to a local LAN / internet, it will be easier to monitor remotely from a tablet or mobile phone. You cannot use two cerbos in one system and will have the problem of connecting the MPPT to the remote Cerbo. If it was a VE.Can model (unfortunately it is only a Smartsolar in the EasySolar II) you can connect it via a standard RJ45 cable as 10m is the longest VE.Direct cable available.
