Thanks all. I might have to do something with the alternator. If they were handing out Oscars for 'Best Solar Forum' this one would get it!!

I was trying to keep things simple with 12V batteries. A 24V to 12V step step down sounds like a much better idea. Can you point me at a suitable device. Also, If I want to use the boats 12V system to charge the 24V LiFePO how do I do that?

That's a good question. In a typical scenario we might be on a long sea passage running navigation electronics and 2 fridges. The 420Ah 12V lead acid would deplete by 170Ah per day (~2kWh). The PV recharges to 100% by mid afternoon on an ocean passage. The current would rarely exceed 10A. On...

I'm new to the practicalities on Lithium and PV, but I do understand power electric generally. I'm struggling to convert my knowledge into practical component selection. Any help is much appreciated. Is this possible and how do I run a 3000W 230VAC inverter off a 200Ah 12V LiFePO battery? - I'm...

That's really useful. I have a background in electrical engineering, but 'all theory'. It's difficult to make product choices without practical knowledge of the market. Maybe I need to go discrete rather than all-in-one to get 12V.... and that's a whole new collection of products to choose from!!

In Will's (excellent) vid 'Budget DIY Ecoflow Delta Pro! More power for less money' he describes a 48v portable system. I'd like to build something similar, at leat 2000W out, but with a 12V LiFePO battery. This is so that I can connect the battery directly to the boats 12vdc circuit in an...
