I have a job existing with 3 MPPTs connected with a Cerbo GX and need to add in a shunt.
Reading the online manual for the Cerbo GX it only supports 3 ve.direct devices due to cpu power limitaions, but my supplier said a 4th one running off the usb to ve direct will work.
The lynx shunt is too exspensive and not practical here. Should I get the depricated vbc ve.net shunt or go for the 4th ve.direct to usb connection?
"The listed maximum on the `Performance` section in above table is the total connected VE.Direct devices such as MPPT Solar Charge controllers. Total means all directly connected devices plus the devices connected over USB. The limit is mostly bound by CPU processing power. Note that there is also a limit to the other type of devices of which often multiple are connected: PV Inverters. Up to three or four three phase inverters can typically be monitored on a CCGX. Higher power CPU devices can monitor more. "
Or am I interpreting this note incorrectly?
