I've wired up my solar panel and now want to fit the CSB2 device. Best place to fit? At the split charge relay in the engine bay (a bit of a hostile environment and can't see the LED)? At the inputs to the Sargent PSU2007 charger (this has cab and leisure battery inputs so I could splice in ....and could see the CSB2)? I've sent an email to Sargent but I'm sure they would not condone fitting anything near their unit. Or completely independant wiring to vehicle battery? How have others done it?

I've had a response from Sargent (very good customer care). Their only negative comment was that when the vehicle engine starts the PSU connects the two batteries together effectively shorting the CSB-2 out. Will this damage the CSB-2? I'm sure that all installations of this unit will suffer this and I've not seen lots of posts about blown up CSB-2s. I've emailed CBE but they are on summer shutdown until the end of the month!

An old thread but I'm just fitting a solar panel and csb-2 split charge relay. @simbadog I like the sound of putting it near my regulator but where did you wire into ?
@stevec did you get a reply from cbe ?
Thanks in advance.

No the battery parallel with the engine running will not affect the CSB2 nor a battery master.
On this Autotrail I mounted it below the EC200

I wired mine into the wiring on the distribution unit using the wiring diagram from Sargents website. Both vehicle and leisure battery connections there, so easy to wire in the CSB2. Performed well for the 15 months we had the MH (recently sold). My next van has an Electroblok unit fitted so I have a Schaudt regulator which charges both batteries.
