Unused CTEK D250SE and CTEK Smartpass 120S

[RoaminRog]

I have for sale a Ctek D250SE battery charger together with a Ctek Smartpass 120S.
Although they are secondhand they have never been used. They can charge every type of 12v battery including Lithium. All they need is an input voltage of between 11.5v and 23v from your solar panel. They are also B2B.
To buy them new would cost well over £500 but I am looking for offers in the region of £250
If you find this to be of interest, please PM me with your offer.
Happy to bring along to Jurassic /New Forest/Hereford Meets or collect in person from Norfolk

Hi Rodger, are all the wiring and fuses still in the kit your selling. Phil

Hi, basically no. This unit will require cabling from the Solar Panel and then to the batteries including the engine battery. It is an extremely powerful unit, handling up to 800A I’m told.
I have the slightly older model fitted and it has worked tirelessly for five years so far without a hitch. They are simply fit and forget. But you must check that the input from your solar panel is between 11.5 and 23 volts. The two units together will charge any type of 12v battery including Lithium.
Although I’m describing these as second hand, they have never been used and are still in the boxes, hence no cabling.
Hope this helps,
Rog

Exactly what bit me on the bum with the ones I had planned on using....

I was slightly gutted as they seemed like fantastic quality kit....
Ended up with Victron after a brief flirtation with Ring.

IF someone has got panels with a voltage the Ctek can use....
They won't be disappointed with these

Most "12V" panels have a Voc lower than 23V so should not be too tricky I think? All the 100W panels I have bought in the past have all been within that spec. The problems tend to be with the large >250W panels which are usually "24V" panels.

Having something like the Victron is a nice luxury - I have two victron 100/20s - got 3 panels in parallel on one of them (so ~21V) and 3 panels in series on the other (so ~63V). On the old camper had series/parallel combo (so ~42V) but I did try them all parallel and also all series (~84V). That flexibility to do what you want is fun, but I have found no actual downside in keeping all panels in parallel so using the CTEK with that limitation is no real limitation in fact

The lowish Voltage on the CTEK MPPT seems to be a common factor on most Combo B2B/MPPTs. The only one I know of which has a highish voltage is the Ablemail AMS B2B/MPPT which can take upto 32V - but even then that is not a great advantage as 24V panels are over 32V anyway.
