Hi, I have looked but remain confused… I’m sure this MUST have been covered before though so apologise in advance. We have 5x 100-50 MPPT controllers (5x circa 1Kw PV strings), 2x MultiPlus Inverter/Chargers & circa 15KwH of Lithium batteries with 1x Cerbo GX. DVCC is enabled. The MultiPlus units, Lithium & Cerbo all work pretty much as expected 👍😀 So I’m now at the point of connecting the 5x MPPTs. These 5 are connected as a smart network and I now need to connect ‘them’ to the Cerbo… Would 1x VE.direct cable achieve this (master MPPT in the network to the Cerbo) or does each MPPT (master & slaves) need its own dedicated connection ? I fully understand that the MPPT smart network is achieved using BT and that there are only 3x VE.direct ‘slots’ on the Cerbo and would need to adopt a USB-style approach should all 5 need a connection… I don’t yet have the MPPTs fully connected (but have laid in 1x VE.direct cable) and would prefer to get it right whilst at the cable laying stage / before closing the trunking etc rather than having to open everything up after finally connect to the PV strings… Thanks in advance. ---

Each MPPT needs to be connected to the GX device and the Smart network should be disabled. > **[4. Connecting Victron products](https://www.victronenergy.com/media/pg/Cerbo_GX/en/connecting-victron-products.html#UUID-6a3008bc-0383-455e-477b-981b4a653685)** ---

VE Smart Network and VE Direct do not always play together nicely, often giving erratic results. ---

No plans for a SmartShunt? That would be another VE.direct cable ---

Good idea but we’d still be one link / cable / connection short… We’re currently thinking that : 1: we will add a SmartShunt to measure wind generator output 2: we will connect the SmartShunt with the 5x MPPT controllers via (6x VE. Direct → USB cables) to a local powered hub. 3: route the USB hub cable back to the Cerbo Seems a reasonable (if a little expensive) solution. Then, as mentioned in another post, switch off the Smart MPPT networking and… in theory, all will be well. Thanks to all for your solutions - appreciated. ---

Thanks. I wasn’t aware of that. ---

Thank you ! 5x VE.Direct, 1x 13v powered USB hub/switch and 1x 3m USB cable ordered. 👍
