I have recently installed new batteries on my Multiplus 24/3000 and since then the fan is running most of the time, while the mains power is on and the charger is on float (i.e. no heavy charging should be happening). Why could that be? I had very depleted batteries before this and in the 6 months I have been running them the fan would hardly come on when in float mode. Nothing changed in the settings of the multiplus, only changed batteries.
You might want to mention how hot you multiplus is getting....
Olde worn out batteries might not need your multi to charge to a high rate.
New batteries might be able to absorb a higher charge rate.
Thanks, it's basically cold. I don't have a temperature indicator (except the little led light if it gets too hot, but that one is not on). But the whole system (batteries and inverter) feels very cool. The batteries are hardly used, as the power supply from the mains is very stable these weeks, so the system is almost all the time in 'float' operation. In my understanding that does mean no high charge rates at all.
