My Bessacarr 725 is essentially the same vehicle as yours.
Last Autumn my battery failed due to a bad cell and had to be replaced. Vehicle had been sitting outside the house on solar for some months.
I have never seen the battery warning you mention, when the battery failed, or when a replacement was fitted. Just the engine didn't turn over.
Solar is usually set up to charge the hab battery, with a Battery Master or similar to keep the van battery topped up too. If your solar was disconnected, is the hab battery down too?
If it is just the van battery, and the hab battery is OK, I'm wondering if maybe you have an earth affecting the van battery only, and that is what the warning light is telling you? If the battery died, what was draining it in that timescale?
Sorry, bit of a ramble, just putting my initial thoughts into words.
I'm daft and proud of it.
