ctek

Main battery is completely flat, I am perplexed as I have a ctek and a solar panel so how has it run flat? I’m going to try jump start it tomorrow. Set up is 140 solar with Victron MPPT15/75 a ctek 250se and a agm leisure battery. I thought the starter battery would be charged first. Any ideas...

I have just fitted the ctek and she works a treat, sat there relooking at the instructions.. page 7 got me a little.. i have smart alternator in the new t6.. but im using my 110ah old leisure from my t5 conversion... Small black wire.. i initially earthed.. Now.. i'm not convinced.. see...

So annoyed with myself. Rejigged all the electrics under the drivers seat. Put the drivers seat back on and the 2 wires out the top of the ctek foul a bar under the seat. Any thoughts as to cutting away the insulation on the ctek sense wires and making god with hot glue or do I need to move the...

Hi, Hoping someone can shed some light on my issues below please... hoping to go away soon! DC-DC CTEK D250SE New charger (with NO smartpass). 2x 100ah AGMs, 2x 100W (19v) Solar in series. My solar is intermittent every 70 seconds or so, but the correct lights are showing. It seems like this...

I have a ctek mxs 7.0 with power supply mode and want to connect the ctek comfort connect cigarette lighter outlet as a 12volt outlet BUT both the charger and the cigarette lighter outlet have the same female connections so wont join any ideas on what is the correct part with Male connector or...

Hi fellow Dubbers. This weeks video is a solar install using the Skyline Roofs 150W solar panel kit and CTEK SE connection. A little geeky chat about PWM and MPPT too Also going to give away the PWM controller to one viewer, so check out the video and see what you think

Hi all, just installed a ctek 250se and leisure battery into my t6. All working fine but noticed when engine is turned off all the lights on the ctek go out as normal and then every few minutes the green power light flashes a few times. Was just wondering if anyone knew if that's normal or not...

Hi All, First post so please go easy. I have searched the forum but I haven't found any other posts on this. I fitted my CTEK 250SE DC to DC charger around 2 months ago and all was working as expected , I would start the engine and after a few seconds the CTEK would start up and charge the...

Connected up my solar last night, so from panel down through the van to mc4 connectors under the passenger seat (with 200a power analyser) to a Ctek d250 under the driver seat. Tested this morning and have 21v to under passenger seat, nothing on the power analyser?? And across the ctek 3v...

Hi, I’ve got my ctek 250 set for agm battery which as I understand should be 14.7v the bmv says 14.99v and has fluctuatedto just over 15v When charging with engine running. is this ok or is something amiss? Thanks rob.

Yesterday I noticed something that I hadn't seen before. Probably because I have the drivers seat out for another job and noticed it but thought I'd check. I had EHU connected which was powering a Victron Energy IP22 12\15. This was charging the leisure battery. I also had a Victron Energy...

Hi All, I was experiencing that my starter battery was going flat due to not being used during this lock down. So, with help from @Dellmassive. He suggested that i bought a 50w solar panel and to connect it to one of the 12v sockets in the dashboard. I also bought 2 x BM2 battery monitors and...

Hi guys, hoping someone can point me to what the various led combinations on the CTEK mean. I can't find what I'm looking for in the manual so don't know if it is correct or not. The CTEK has just been installed (not by me) and as it is under the drivers seat it is quite hard to get to to...

Hi Guys Hope someone can help. Im just wiring in aCtek d250SE to my 2017 Vw T6 (Euro 6 Start stop engine). Think I've done it right but the green light comes on the ctek but nothing else so it doesn't look that its charging my leisure battery. Where am I going wrong??Any ideas

If I buy the cbe pc180 distribution system do I also need a ctek 250se to charge the leisure battery from the alternator ?? Thks

Hi all, the alternator light on my ctek 250 is flashing, any ideas please....cheers.

Hi I'll be getting myself a DC/DC charger to replace the current smart relay set up soon. As the first step before i go solar, ideally i'd want one with a built in MPPT solar controller, so was wondering if any one has any recommendations as to what to get? Been looking at the CTEK D250sE (or...

I'm planning on fitting a solar panel on my van, looking at the photonic universe 160W semi flexible. But scanning through some posts on here i found out i need to now upgrade my existing leisure battery setup. My van is 16 plate euro 5 engine T28 so has stop/start bluemotion, was an exhire...

Hi everyone Does anyone know anything about these CTek split chargers? I've built my own campervan and read alot about T6s and their smart alternators etc. So I bought a CTek split charger and wired it all in. It all works fine, the solar charges the new leasure battery and the alternator...
