240v hook up battery charge.

[Stratto]

I've bought a smart charger for vehicle battery, I can turn the hab battery charger off independently so its no big deal.
The problem was the vehicle battery not being maintained which I've done what Wildbus said, just with a more in budget smart charger.
It's a 07 plate moho, so I fully understand its not going to have the most modern or best quality equipment on it.
Thanks for your help.

I have 400watts of self installed solar although a 100watt to 200watt would work. The solar is great as it tops up the battery and keeps the load off when using 12v systems like pump and TV so there is always some power in the tank. Which is not so important if you go to sites on EHU so your best option is a smart charger plugged in.

No it will not charge as part of the mains hookup. Using EHU to charge your leisure battery is not very efficient and can shorten the life of your leisure battery as it is not a smart charger it’s a power supply that just outputs the same voltage no matter how much the battery is charged. You can either use a smart charger plugged in or use a solar panel connect the vehicle battery to the leisure battery via a box to divert the solar charged leisure battery to the vehicle battery

I never realised this, thanks for pointing it out. In future I will only charge hab battery as required and not leave it on all time with elec hook up. I did wonder what the point of the charge on / off switch is but it makes sense now.

I am planning to fit solar panels but not got round to the research on what to fit yet.
I am very practical and good with hand and electrical work doesn't phase me but I've no great experience with Moho related stuff as last year was our 1st full year of ownership.
Moho also has a few angles to roof and 4 skylights and an aerial so I'm going to have to be clever with using the space available, but yeah SPs are def on the to do list.

Use a timer plug for the old van hab chargers, maybe 2-3 hours, 2-3 days a week will more than keep up if there is nothing drawing power.

I seem to have the perfect setup thanks to Merlins GizzMott device.

It’s not a charger it’s a power distribution with a power supply that outputs a set voltage that can fry your battery

Using EHU to charge your leisure battery is not very efficient and can shorten the life of your leisure battery as it is not a smart charger it’s a power supply

That's not true for the Nordelettronica chargers, Stratto, they are bona fide chargers with adjustable absorbtion and float voltages.

I've posted this photo a couple of times on different threads, but it might be of interest and relevance to your comment above?
On my Motorhome, the front part is a dome so nothing can be fitted on it (most vans with a overcab lump have an angled but flat section that can be used). Behind that I have a TV Aerial, a large skylight and 2 more smaller vents and a satellite dish, but choosing my panels carefully, I have covered all flat parts with PV Panels.

Since I did this, Photonic Universe has introduced a range of solar panels that are narrow and ultra-narrow and I selected various sized panels from that range to fill this Malibu roof with as much solar as possible while still accomodating a rather large satellite dish as well the roof skylights and fridge & heater vent.

Both methods work well. Using the semi-flexible panel option gives a much neater option on a roof than the glass panels and for sure is the better option for a motorhome like that. On my Autotrail the side walls extend quite a few inches up from the roof so the multitude of solar panels cannot be seen unless you are above the van so in the case of a Motorhome like that, the appearance is not affected at all.

(Of course, to many, function is all and the asthetics are not a factor, but it is nice to have a smart looking solution IMO).

That's interesting, I will take a look at the Photonic Universe SPs. Thanks for the tip.

I have one of theirs, it has the facility to do the VB too.
