The MPPT’s will limit themselves. I also strongly believe it is best to use 3 seperate small MPPT’s in case of shading. This will give you the maximum possible power is any shading condition. It also allows you to use thinner and therefore safer cables. 3 x 100/30 would give you 360W for every panel…

Sorry I’m using scc as an abbreviation for solar charge controller there. So in your case you could swap your smart solars for blue solars and they’d still coordinate like they do now. Coordination is not dependent on the “smart” version of the solar charge controller, when using hard wired comms t…

This is a GREAT thread, many thanks to everyone for contributing to it! On my setup my shunt has the special temperature sensor and the shunt is connected to the Cerbo using a VE cable. This means the temperature is ‘broadcast’ to all devices on the network. This works. I’m still wondering whether…

[image] BobKones: I’m still not sure if you can configure them 100% through the portal. Config is thru the Victron Connect app, not the vrm portal.

[image] Brucey: However my sccs still co-ordinate fine in terms of switching from absorb to float, reducing output on certain trackers to match float loads etc. Via ve.direct and ve.can to cerbo. I tried it again. I removes all MPPTs an the shunt from Ve.Networking. This is the result: [ima…

Looks like SVS wasn’t enabled in the cerbo given the differing voltages? Here’s what my settings look like, voltages stay very close together: [Screenshot_20260814_100217_VRM] [Screenshot_20260814_100420]

[image] Brucey: Looks like SVS wasn’t enabled in the cerbo given the differing voltages? yes, because DVCC is off

Unfortunately, they split this wonderful topic. That’s what I get for thanking everyone for it ! :slight_smile: Ok, So I returned the 150/85 controller and chose to get (3) of the 100/30’s, as recommended, but I got them with the Bluetooth option thinking that maybe, if I’m lucky, they can be on th…

[image] BobKones: So my hope is that the 3 controllers will make their own network, sync their charging, get the temperature from the VeBus and it will all work with DCC. Something tells me this might not work. I’m guessing they will sync themselves but without the VeDirect cables and the hub, …

[image] BobKones: Unfortunately, they split this wonderful topic. That’s what I get for thanking everyone for it ! :slight_smile: We ask in our guidelines to keep a topic to one subject, it had meandered into a general mppt discussion which makes it difficult to benefit others in future. So…
