Hi everyone,

I’m currently troubleshooting a strange issue with my **Cerbo** and a **Smart IP43 120–240V charger (3 outputs)**. Both devices are connected via **VE.Direct**.

When the batteries are charging, the **Lynx Shunt** reports **much higher wattage on “Battery” than what is shown under “DC Loads”** (see attached example photo). This happens even though **there are no actual DC loads active** during charging.

If I **disconnect the VE.Direct cable** from the Cerbo, the wattage shown on the Lynx Shunt for **Battery** and **DC Loads becomes identical** , which is what I would normally expect.

What I’ve noticed is:

- The wattage shown under **DC Loads** corresponds exactly to _voltage × the current from output 1_ of the Smart IP43 charger.

- It appears the charger is only reporting the **current from the first output** , not the **combined output of all three charging circuits**.

Has anyone seen this behavior before, or knows whether the IP43 should be reporting the **total output current** over VE.Direct? Any ideas or suggestions would be greatly appreciated.
