Hi, I will put some pictures up in due course. I have a multiplus 2kva that handles the ehu, with 80a charging the house batt and 4a for the starter. This is still valid even when not on ehu, it still trickles the starter. Solar, 600w on the roof with a 100/50 mppt and 230w on a 100/20 mppt, portable, that only gets out if we are stationary for the day. At some point, I will make them to slide out from under main panels as a awning. Still working on that. The B2B is just a victron dc-dc converter, triggered by life feed under seat on low signal. This a factory provision for GB vans conversion; becomes life when engine off, and cuts off when engine is running. Hence is on the low signal. Also I have a switch, as we only use it in winter months when not much solar. The converter does get pretty hot, so I plan to upgrade that. When we did the van the dc smart was not out yet. I also have a batt sense networked with the chargers to control low temp charging. All connected to a raspberry pi and touch display, wired on wifi, life on vrm. This is handy as I can turn on hot water remote and have not to wait for shower when we get to the van. The wifi is a Rutland rux11 router with a mimo 3/4/5G antenna on the roof. So far we had singnal everywhere. The vrm provides a geofence alert as well.
What I would done differently, is the diesel heater controller. I really need to get a afterburner so I can control that remote to. At the moment we rely on thermostatic controlled gas propex when remote, and eats in our small gas supply. Only 20L underslung. We do use our van 8-10 months of the year.
