Hi you dont mention what type of PV chargers you have attached ie is one a Victron Smartsolar and the other a grid tie unit, and as Klim also says if its night time and there is no voltage then it may turn off fully at night , so please check during the day, as normally if they are smart MPPT they show, also check the firmware that the smart solar units are on and if need be upgrade the firmware , as you may have a difference there as well

please advise on how both can be shown the amps and volts on the pv side

Tnx

Are both systems running the latest FW versions? (GX device and MPPT)

I see the secound unit has a grid lost alarm please clear this and check again

some thing is set differently, or there is different equipment on one to the other. ie a smart shunt on one and not the other, DVCC turned on on one units GX and not the other. check all setting are ALL the same IN ALL devices. and compare like for like

Note both should be showing, and I do not know why the first one is not showing if you have all the latest firmware's on BOTH systems

some thing is set differently, or there is different equipment on one to the other. ie a smart shunt on one and not the other, DVCC turned on on one units GX and not the other. check all setting are ALL the same.

to find this you will have to do diagnostic's

clear the grid error
reconnect the grid

you may need to do some swapping around. IE swap the 2 mppt units over and see if the problem transposes.

these are just guess's and possible place's to look

Hi @Andre de lange

What you haven't made clear is that the 'offending' installation has multiple mppts. Does the other that you're using for comparison?

I'd suggest this is the issue, and it may not be VRM, but instead possibly the way Venus treats data from multiple mppts.

Hi John yes the one installation does indeed have two MPPTs and this is the installation not showing the pv volts and amps. Is there a wou around this or is it going to be added in the future ?

We are running a colour control on both installations

Tnx again

André

With multiple chargers it does not seem to show pv voltage etc. My installs are the same.

I see the same on my systems and makes sense when you think about it. With 2 (or more) MPPTs and different panel arrays, how would it know which PV volts & amps to display? Amps could be summed but volts would make no sense.

Magic! Multiple PV data added overnight. Great work VRM team.

Yes, it is nice but room for improvment still.


It seems static and appears to update once a minute?


Also , voltage and amps probably clutters the view , just wattage would be better I think , or an option to customise view.


I say this , because on my iphone SE ( small screen ) it just shows me the Volts and cuts out rest of the more important information , ie. WATTS

Just turn the phone onto its side for a landscape view, works just fine.

And you can also horizontally scroll the detail box!

OK, that works , but I still believe total WATTS generated is alot more inportant than the PV array voltage and amps , as the first displayed figures, which would reduce the " finger " interaction with the phone.


So , if I may suggest , WATTS first , then Volts and amps ( if they have to be displayed at all )


Also , make it dynamic update , second intervals , exactly same as total Watts updates , then I give the full marks :-)

Hi VRM team ! You are inches away from my full marks :-) I can see now the information updates every second for the individual PV arrays , which is great.


Is it also possible to have the WATTS displayed and the Volts and Amps after that?

Total power is surely more important as the initial display figure Volts / Current , which would also prevent scrolling on the phone , I know you can have the phone in landscape mode , but you still have to scroll down to get to the PV Charger section ( on a smaller phone ) , which still requires unneccessary interaction , not only rotate the phone and still have to scroll down on VRM dashboard view.

Nice feature indeed.

Have 5 mmpt's here but only the fist two in the list are updating continous.
The others appear to be static and update only on reload.

Hi All,

Do not want to open a new thread, but seems that after a recent change in the VRM (during the last several days), this problem is present again - NO PV data is show in VRM dashboard (details are enabled). Only the power(Wats) going to the battery is seen in the PV box, but not the rest of the details seen previously.

I must emphasize that this is valid for VIctron PV chargers and even for Fronius PV inverters. I have 3 installations and the data is not shown for any of them (the PV sources).

Here are three shots of the 3 installations:
1) with PV inverter
2) with Victron MPPT 450/100
3) with Victron MPPT 150/35
It used to show the PV voltage, the PV power and the charge power that is going to the battery under the PV charger box in the VRM dashboard. This was all seen before several days, so it is definitely a change in the VRM, not my setup.
