Smart MPPT 150/100 remote switch

In our sites we have two or more smart solar mppt 150/100 or 250/100, when we can test our batteries we need to shutdown our controllers, ¿Can I connect two or more remote switch control in parallel mode?? or we need a Normal Close relay for each one?


Thanks for your support

There are a few options depending upon your setup.

If you have a two or more MPPT's connected to the same battery bank, then you can use one relay to controll all MPPT's, Connect a relay to battery - terminal and then the other to the L terminal of the remote connector of each MPPT for normal operation.
Or connect a relay from battery + terminal to the H terminal of the remote connector of each MPPT for normal operation.

If MPPT's are connected on different battery banks then use one relay for each MPPT connecting H and L together for normal operation.
