Rooftop Solar on Factory Rack

Yes, Setting 2 is the default, and likely correct choice. I’ll see what Victron say.

I’m interested to hear because looking on line from different manufacturers it seems you can charge anywhere between 14.3v and 14.7v. I had a message back from my dealers and they said to charge the batteries on the regular setting.

I’ve just ordered my solar setup gear. 1 x 270 watt Photonic universe semi flexible solar panel.. 1x Victron 100/20 mppt controller and all the associated bits and pieces. The solar panel will be stuck on top of my Alucab roof. I went for the smaller Victron charge controller as I’m tight for space in the battery box. It’s has a maximum capacity of 290 watts so good enough for the size solar panel I’ve ordered. I’m going to fuse either side of the controller using maxi fuse holders.

Seems Victron support is well hidden behind non-phone communication. I submitted support ticket.

Here is the active screen showing voltages.

In hindsight I could have used the 100/20 but didn’t have a good feeling on how much solar I will need or use. I also fused the controller from both sides.

Here is the reply. Victron forwards the inquiry to the their dealer that sold the product, so not a direct Victron reply.

To directly address your inquiry:

There does not exist any Victron preset for EFB batteries; your best option is to locate the user and installation manual for your batteries to find the recommended charging parameters for them, and then select either the preset that most closely matches them or, more preferably, use the VictronConnect app to set your own custom charging profile to ensure that the batteries are being appropriately charged.

The EFB chemistry is not widely used -in fact this is the first time we've ever heard of any OEM system using them- so we unfortunately have zero background to go off of to make recommendations for you, thus our suggestion to revert to your battery user manual for their charge recommendation. In theory position 2 on the rotary switch should be relatively safe, but absolutely refer to your battery manual be sure!

So position two for now. I am still awaiting the charging profile from Ineos

In the interim, the Moll EFB tech spec says to charge at 14.4v. The maximum charge voltage is 14.8v. It also says to completely disconnect the battery from the vehicle before charging
