300w Solar Panel Installation for the Ctek D250SE 

Came here for the CTEK, stayed for the funky music!!! Good stuff

Thanks. This video helps a lot! If you may I do have two questions. 1) I do have three AGM leisure batteries with 115ah each, can I still use the CTEK 250SE? I read that is limited to up 300ah. 2) I'm doing a research about the usage of CTEK Smartpass along with 250SE, which benefits I will have with that?

Hi i have the same Ctek charger and about to add 2 x 100watt panels. As it doesnt have a visual display how do you check amperage its supplying.

you should have your solar panels in series to up the Volts to always have a generous amount of volts for your batteries. Almost no one does parallel on a van roof. For many reasons. your way is high amperage and low volts. Change your mppt. I got a couple of useful tips from this video mind and i recieved my solar array today so waiting for a dry day to fit it all. thanks a lot

Good morning. Great video, it's exactly what I was searching for. I have a question, potentially a stupid one (sorry). If I have a 100W pannel going to the CTEK do I still need the 30A fuse or can I use a smaller one? Thanks in advance.

Hello

Hello dude, what did you do with the ignition live wires from the CTEK if your not attaching them to an ignition live? Struggling with my CTEK on my sprinter, cant seem to get it to charge and thinking it may not actually have a smart alternator, mines 2015, what year is yours?

Hi, just bought a ctek s250 and a smartpass combo and I’ve found your video helpful. Just got a question. I have 600ah lithium and I want to be able to charge my battery mainly from solar so aiming for 600-700w of solar. Will the ctek and smartpass together be able to handle that much solar output? Thank you.

But is the solar controller a mppt ? If not you will not get so much as 5 amp in charging. Anyway great video!

Hi I noticed u have a vent infromt of your solar panels thar is the size I am trying to get can u provide the supplier for me cheers dave

Those holes you drilled for the cables where u put the grommets, I hope you protected the cut metal with paint or those bad boys are gonna rust like hell. That cable passthru thingy is a condensation maker2000, at least now when you prevented air to circulate in the cable gland by putting grommets on the cable pass thrus.
