I have posted a few times about my desire to install Solar and a BTB charger, and have nearly decided what to do.
I will have a dedicated Solar Charge Controller, connected to the Leisure Battery, and not make use of the existing wiring from the EC225. Would I still need a "Battery Master" if I have a BTB Charger? Will the two work together?
However, I am still not sure how to modify the wiring to allow a BTB charger to work correctly.
I sent the following to Sargent Tech Support, but have had no reply.
Is anyone on the forum able to help?
"I have a 2008 Autotrail Excel 600B, fitted with a Sargent EC225 Power Supply and EC100 Control Panel.
I wish to add a “Battery-to-Battery” charger, to enable quicker/more efficient (4-stage) charging of the leisure battery when it is being charged by the Alternator.
In order for the BTB charger to work, I will need to remove the existing input from the Alternator to the leisure battery. I assume this is controlled by some sort of split-charge or voltage-sensing relay, but may also go through the EC225.
However, I will still want there to be a 12v supply to the fridge when the engine is running, and also for the Leisure Battery to charge, via the EC225, when on EHU. I assume that the EC225 also needs a signal to switch-off the 12v supplies (lights/sockets etc) when the engine is running, to comply with regulations.
Are you able to advise me of the modifications to the wiring that I will need to make to enable the BTB charger to work correctly? Are you able to supply any wiring diagrams – more comprehensive than the one in the EC225 Instructions?"
Thanks,
John
