@MoorHamish this caught me out badly on my narrowboat last winter too. Worth checking whether your inverter is drawing phantom loads overnight — mine was pulling 15-20W in standby constantly,...

@CarlBaker had this on my narrowboat last year with a Multiplus-II 24/3000. Turned out my tail current setting was way too high — it was seeing the current drop to that threshold and assuming the...

@MariaJones interesting you mention the Fogstar throttling — I saw something similar on mine last winter.

@BordersOffGrid 😂 gap year is exactly right Worth knowing why though — PWM can only work once panel voltage rises above battery voltage by a small margin.

Worth adding from my own experience on the boat — even once Victron transfer ownership to you, double-check that any scheduled charging profiles or ESS settings the installer configured are...

Worth adding — if you're running a BMS with a charge disconnect relay, that can silently pull the load away from the MPPT and it just sits there looking confused showing "off".
