I have 5 x Smart 250/100 charge controllers connected via Can Bus to an Ekrano GX device.
Latest firmware installed on all devices. Can Bus termination plugs installed. All patch leads tested.
Smart Mppts plus smart shunt all networked together via Bluetooth network as well.
Works fine for about a week, then disappears off VRM. Reboot the Ekrano and the Smart Mppts pop back for another 5 to 7 days then disappear again. Done this consistently since commissioning.
Other devices connected to Ekrano
2 x 10kVA Quattro
1 x Smart Shunt
Everything is working fine other than the MPPTs consistently dropping off VRM
Hi im not sure but i dont think you can not connect CAN and bluetooth at the same time… try them without bluetooth connection and see if they stat connected
Yes I’ve done that already.
I believe it’s not a problem to BT smart network the MPPTs and connect as Can Bus chain and haven’t had an issue with other sites with this configuration.
But I ran the system for about a month without BT networking and the same drop outs occurred.
Maybe you can see something in the logs after it happened, when logging in via ssh (root access enabled on the Ekrano) e.g. in: /var/log/vecan-dbus.can0/current (there are many different logs in /var/log/*/current for all the possible components)
