System Schematic for a simple (non-Lithium) Victron boat setup?

I love the system schematics Victron has posted under the MultiPlus II "system schematics" tab: https://www.victronenergy.com/inverters-chargers/multiplus-ii#system-schematics

Ex: https://www.victronenergy.com/upload/documents/MultiPlus-II-3KW-120VAC-12VDC-400Ah-Li-VEBus-BMS-generator-MPPT-BMV-Cerbo-Orion-Tr-Smarts.pdf

But they're rather complicated for my entry-level point of view... they're like the use-all-the-Victron-products example. Anyone know of a schematic example for a more base case / bare bones Victron setup - ex, without lithium batteries, say just 300 Ah AGMs, solar, an inverter/charger, and SmartShunt with Cerbo GX + Touch GX?


I'm building a new system on a boat and want it to be future ready for Lithium, but I don't necessarily need all that complexity now. Ex, I believe a non-Lithium schematic wouldn't require VE.Bus BMS, the Smart Battery Protects, and the Orion-Tr DC-DC chargers.

Orions are there to charge from the engine's alternator. So optional irrespective of battery.

Smart battery protect optional. You can trigger alarms from the Cerbo. Lithium BMS will often do all you need

VE bus BMS only for Victron lithium's. Other lithium's have an inbuilt BMS, or use an external one.

Simply leave out the components you don't need, using the existing schematic. The idea of the schematics is to show what's possible/how it fits together, not to sell kit.
