Charge setting

Post by Cisco Ken »

I have an MX60 and a Flexmax 60 charge controller along with two VFX3648 inverters and a Mate 3.

When I go to the charger setting of the Mate for the controllers, why can't I change ports? It stays on port 4 which is the FlexMax controller. I want to be able to set the charge current for the MX60. Unfortunately the Go button on the MX60 no longer works so I have to use the Mate to change settings.

Another question I have is whether I should add a second RTD to the MX60 directly as recommended by one post on this forum.

To my knowledge, the MX60 never really supported setting changes via the remote - it was display only. There's also a lot of settings and values that only the FM60/80 or newer controllers support.

Phil is right, you can only change the MX60 settings locally on the MX60'S keypad.

You do not need another RTS. My system has one connected to the master inverter on port 1 of the Hub, and all other devices use the correct temperature compensated voltages for control setpoints. The manual for my GVFX3524's specifically states, "When a HUB is used, the RTS must be plugged into the Master GFX which must be plugged into port 1 of the HUB. If this is the case, only one RTS is required for all devices plugged into the HUB."
