Hello guys new here but reading some posts have found it to be the most friendliest so here I am.. I have a CBE DS520 and on the PC380 it shows a solar symbol on power up. Now my question is how do I tell the unit to use split charging on solar my MH is parked across the road in a secure yard and not easy to get EHU to it to keep both HAB and CAB batteries charged all year round I found a walk around by using a jump lead from the ‘+’ HAB to CAB but I had an issue with solar failing and killed all my batteries I have briefly spoken with apuljack who said that you only need one wire connected somewhere to activate this the wiring diagram could be sent out after they repaired my unit however the only thing wrong with it is the amp measurement is showing -amps and for £180 + parts is something I can live without this was also a result of the solar going down. I have searched high low middle and everything in between looked at countless wiring diagrams and schematics and cannot find this simple but very useful information. I have looked at D+ signal and charge signal from controller as options but don’t want to cause a problem with fridges and lighting. Sorry for the long post I’m hoping I have covered everything I’m needing and the things I have done so thank you for getting this far.
