I have some questions about the ctek 250se

[Mr blue]

Hi all I have the ctek 250se installed and have read the Manual but still not sure
Q. If I put a internal battery charger on it as in the instructions will it charge (on hook up) the leisure battery till full and then charge the starting battery after ?
Q if I install a solar panel will it charge both batteries like above
Or just leisure battery and can I just put the panel output directly into the ctek ?
Many thanks

Q. If I put a internal battery charger on it as in the instructions will it charge (on hook up) the leisure battery till full and then charge the starting battery after ?
- if you put a EHU battery charger connected to the starter battery, then the voltage rises to 13.1 for 5s the cteck will start charging the Aux battery. . . . .
- if EHU connected to Aux battery, the ctek will not reverse charge the starter . . . (thats solar only)



Q if I install a solar panel will it charge both batteries like above
- yes - with solar it will charge Aux, then when full the Starter





Or just leisure battery and can I just put the panel output directly into the ctek ?
Many thanks

as above . . .

put the panel direct on the ctek, providing thepanel VOC is below 23v VOC




or connect a seperate solar controller to the Aux, or starter battery . .

Mobile Solar Panels ? . . . - How I Did It - There is loads of background to this . . . . . but for now here is a vid for you all. =] Just remember W = V*A and as a general rule a good 100W panel will give you up to 6A charge with good sun. 25w = 1.5A 50W = 3A 100w = 6A 200w = 12A 300w = 18A...

Thanks @Dellmassive I didnt know about the EHU charging part, I can use my 50w panel for the starter battery, leaving the charger to top up the leisure battery as required. Always learn something or perhaps read the bloody instructions properly

 

[Dellmassive]

50w might be a bit low....

It might give you a trickle charge..... but you get the idea.

200w and your cooking . . . .

 

[Blitz]

Yep 50w just connected to dash 12v socket and 240w to the Ctek.

 

[Dellmassive]

Perfect.....

Thatll keep the beers cold nicely...
