The missing piece here is your battery capacity and DoD tolerance. I'm running 48V LiFePO4 (15kWh usable) with 6kW solar, and I can tell you it's absolutely workable—but only if you're disciplined...

Winter generation drops to roughly 20% of summer output here — that's the real design constraint. Most folk size for summer comfort then panic come November.
The real issue is voltage regulation. Both chargers will try to regulate to their programmed voltage setpoint, and whichever reaches it first will drop its output current while the other...
The 150/10 is indeed solid for that spec, but @SaltyRanger's got a point worth considering—what's your actual string voltage under load?
Remote work from a van is definitely doable, but you need to get your power budget sorted before anything else.
@AZY_Marine's got it spot on. I built mine three years ago and the labour cost was eye-watering once I actually tallied it up — probably doubled the material cost.
200Ah LiFePO4 is a solid choice for winter reliability — you'll get proper usable capacity without the DoD anxiety that kills lead-acid setups.
Worth checking your actual winter consumption first...
The 1.6kW cap is sensible for a workshop, but I'd genuinely recommend sorting phantom loads first before you expand. Had a mate with a similar shed setup—his tools were draining 40W just sat idle.
The inrush current is absolutely the killer here—I learned this the hard way with my setup. A standard washing machine can pull 3-4x its running wattage for those first few seconds when the motor...

@FZ_Builds spot on. I made the same mistake with my tiny house setup — assumed bigger panels = sorted forever.
Reality check: it's about usage, not just the panels.
The adhesive's definitely the weak link, but honestly the bigger issue I've found is thermal cycling.
