So the renogy DC to DC with built in mppt is quite a bit cheaper than the ctek but is it as good ?
 
Dunno. But I've got the ctek and it just works. It does have a limit on the solar input power though which may be a decider.
 
It's better IMHO..




 
Thanks guys I did watch a you tube video on the Renogy and it did seem to be a good bit of kit .and with it being quite a bit cheaper I might be swayed away from what I thought I had decided on the ctek.
 
Oh no not more choices is the ctek not very high up on your rating .thanks for taking the time.
 
they are in no particular order.
but for the combi units ( that include solar MPPT ) the renogy is the clear winner for me.

its availible in 30A and 50A versions.

but with the BT adapter you can program and monitor.

so i always say go for the 50A - then set to 20A or 30A - then just turn up the power when you need more ( ie add a lithium battery to your setup)


..........


short cut option :

just get the kit - the (50A dc-dc + Mppt) with the BT-2 BT adapter.

Is there any benefit of having individual units like victron mppt over a combined unit such as the renogy 50A DC-DC & MPPT unit? Do designated MPPT units somehow provide harness more power from your solar panel?
