DCC-850, BC-520, Second Service Battery

Messaggio da Jojo1950 » 14/02/2023, 21:36

I have a Rimor Evo77+, Ford Transit 170 PS, built 12/2021, with booster DCC-850 and 230V-loader BC-520, red 12V-distribution-box, service battery: 92 Ah AGM , built in by Rimor into outside-box.
Now I want to add a second service battery (built in under right front seat). Both service batteries connected by a switch: 1-2-0-1+2 (that means: either bat. 1 or bat.2 or none or both batteries switched to the outlet of the switch.
My question: Must I connect the cable from the outlet of that switch connect to entrance connector B 1 of DCC-850 after disconnecting auxiliary battery from connector B 1 of DCC-850 and connecting to that above mantioned switch?
And: I have mounted a solar controller, 20A (WIN500 bluetooth), directly connected to + and - of actual service battery. Can I connect it instead to solar-input of the red 12V-distribution-box?
Is it correct, that only the service battery and not the Ford-motor-battery is loaded when 230V are connected? Can it be loaded by a standby-charger, connected to Ford- and service battery?
Thanks and greatings

To make the installations described, you must connect the switch output to the two batteries and the input to the output of the dcdc converter (as in the original system). I advise you to install the solar panel regulator directly to the two batteries. If you connect the solar panel to our system, when it doesn't have the batteries connected, the system will always try to turn on through the solar panel.

Me again: if I can secure, that the solar regulator is "off" (switches are already mounted) when the battery-switch is "off", can then the solar regulator be connected to the red power distribution box ePvL (green socket) ? Which kind of connector is to be used?
And: the 230V loader BC-520 does NOT load the FORD-motor-battery when connected to 230V shore power. Can that (how?) be changed ?
Thanks in advance

Hello. 220V charge only service battery. To charge motor battery with 220V you need to install other device.
For solar panel I suggest you to install the regulator on BS and GND on our box.
