Easy Solar & Cerbo

Hi,

I just recently installed Easy Solar with Cerbo and GX Touch along with an AGM supercycle battery into a Mercedes Vario bus converted to a camper. Everything looks ok but I can't get the battery % to appear on the GX Touch so I have no idea of battery state. I connected to SP and fully charged the battery which I thought would then feed the info to the Cerbo through the battery controller in the Easy Solar but that hasn't happened. I have a lead coming from the vehicle battery to the AGM to charge it when driving.

What I am wondering, is there a way to get this working or do I need to install a smart shunt? If I do need to install a smart shunt will this connect to the cerbo via bluetooth or do I need connect with a VE connect cable?

It would be disappointing if I need a battery monitor on top of the Easy Solar.....

Thanks to anyone who can help.

You have to enable the battery monitor in the settings of the EasySolar (with VE.config).

But the EasySolar + Cerbo can only see the current coming from the grid through the MultiPlus (inside the Easy) and from the MPPT connected to the Cerbo via VE.direct.

If you have any other DC charging sources (alternator) or loads you need a SmartShunt to see that current. The SmartShunt have to be connected to the Cerbo via VE.direct.

Hi Matthias,

Thanks for reply, much appreciated. I didn't realise the battery monitor in the Easy Solar wouldn't be able to see the feed from the vehicle alternator or even that it had to be turned on.

When you refer to VE.config do you mean just the VE.connect cable or would I need the MK3 also?

And, even if I enabled the battery monitor using VE. config it still wouldn't recognise the alternator supply? Looks like I need the smartshunt so?

Thanks for the help Matthias

Thanks Matthias. I don't have a cable to connect to the cerbo so will try that tomorrow to enable the battery monitor. Is there an option to run the power through the Easy so it can be picked up by it. The manual showed a possible battery connection but it was at the back and difficult to reach. I have the Easy 12/1600. Going by what you say maybe the best option is just to get the SmartShunt.
