The installation in my camper is as follows:
Multiplus Compact 12/800/35 (shore power / 220AC appliances)
SmartSolar MPPT 150/35
PV Array with 3 solar panels serial 174W 12V
Orion TR 24-12V 30A (Engine running 24V)
As I understand from the documentation, ESS may not be configured. When stationary, I want to have the priority to the solar load and then from the grid if necessary and available. I guess that this is the HUB-1 configuration from the Venus GX configuration. When driving, priority solar and then engine.
If I read it correctly the Multiplus will monitor/manage the Bulk/Absorption/Float/Storage algorithm of the MPPT.
The Orion TR smart is configured up to now (before the installation of the Solar PV) that it will start charging with the engine detection running >26V.
My Question: How to configure/wire the Orion to avoid overloading (respecting the SOC/algorithm) the batteries as it will have 2 algorithms to charge, one triggered by MPPT and the other by Orion. eg: when the batteries are full and no consumption, or when batteries are loaded from solar....
Electrical scheme attached below.
And to be complete, firmware running: Venus v2.54; Multiplus v473; MPPT V1.50; BMV (household) V4.03
