One a newbie
Hooked up last night on site and thought nothing of it. Checked solar this morning and over night the battery went down to 12.17v according to victoron app. Just set up at another site and realised sargent panel saying not mains connections and charger turned off so I flicked it back on it then said mains on but reverse polarity light also came on!
Assume that’s why battery dropped to 12.17 last night. Can I also assume when EHC is connected that takes over charging the battery instead of solar🤷‍♂️
 
on my solar, it seems to drop its rate of charge if the ehu charger is on. I only think this because of observations made with an EPever duo solar charger and my old psu 2007 Yours might be same.
 
Playing safe Ive disconnected EHU .
Shame as I’ll have to turn van around now to catch the sun🤦🏼‍♂️
 
Searches will throw up many threads. I would paste my favourite one but I’m no expert and wouldn’t want to direct you.
 
Generally speaking, unless you've got a special setup, both EHU and solar will charge your batteries together. Then when fully charged the controllers will reduce it down to whatever is subsequently needed. Should be no need to disconnect anything.

The charger ouputing the highest voltage will normally take priority.
It will take care of itself so don't worry about it.

Reverse polarity of the mains should make no difference to the functioning of the charger. If reverse polarity causes any issue, it is an increased risk of electric shock if a fault occurs. All the appliances should function exactly the same as if on normal polarity mains. So whatever your problem is, reverse polarity is not part of it.
 
When you are on hookup, and the mains charger is functioning properly, the battery voltage should go up from its resting voltage (12.0V to 12.7V) up to over 13V. It should get to 13.8V at least. If it's a 3-stage charger it should gradually rise to about 14.5V, then drop down to about 13.5V when it is 100% full. If it isn't doing that then there is something wrong with the charger, or maybe the connections somewhere.

When the sun is shining, the solar should do much the same. You shouldn't be seeing below 13V at all while the hookup is connected and/or the sun is shining. What voltages are you seeing with hookup connected, hookup disconnected with the sun shining, and hookup disconnected when it's dark?
 
Sorry for late reply, saw messaging at 4:30 but wasn’t going to disturb Gill . So I’ve connected EHC and sure enough panel showing 13.6v . I should have checked that yesterday but lesson learned. Thanks for all the advice . Luckily we use very little 240v if any.

Yes we will be looking out for that. Just hoping the sun makes an appearance 🤞🏼

dont forget to take a ride on the petit train from just outside the cathedral and dont forget to ask for the english translated transcript of the trip, makes it a bit easier to understand, though its that 'wordy' its difficult to keep up!
 
Loved the little train, only saw elephants head in passing 🤦🏼‍♂️
Nice place staying in camping car place.

Well so long as I know it’s charging the battery I’m fine. Only a VW T5 so we do t carry much 240v stuff. Ride up to Bayeux tomorrow that will charge everything 👍🏻
