Greetings! The unit does not disconnect completely, it’s just that I have noticed that it does not have the same power as when it was new, it has not reached 6 months of use and my fans move much slower connected to the Inverter than to shore power. It is a simple equipment for a cabin. 400w in solar panels, mppt 150/70, and a chins 200ah lifepo4 battery. When new if I used the fan with the current from the Inverter and then changed it to shore power the fan moved faster with the Inverter, then time passed and now I do not feel that it moves the fans the same or better than the shore power. Is this normal behavior or should I take it under warranty? I have had other inverters from brands such as Wagan, Renogy and Giandel of the same power and always after a few months they feel less powerful.
Hi, it could be…
Equipment ages with time, components degrade (unlikely in such a short time but…)
You just get used to it (imagen a change that is not there) and when changed you just think it is different…
The voltages between the two sources are different???
The voltage is dropping for some reason (battery’s getting low? or wiring/connection issue, something else pulling it down)
But to help in a constructive manner we will need more info, like pictures of your system, screen shots of your setting particular the Inverter setting, do you have a Cerbo, Smartshunt? lots more info please.
Or maybe the inverter is set to 50cps, your grid has 60 ?
I did think of that but discounted it because a 60hz motor (in the fans) run at 50hz would run 20% slower as soon as you turn it on and not decrease over time as described by the OP and would maybe eventually overload and fail earlier.
Well, because i have a US made RV and live in Europe, everything was constructed for 60hz, is running on 50hz for >20 years, nothing has failed yet.
My Multiplus is set to 50Hz, the generator produces 60Hz, we all live together in harmony.
Glad to hear
But this is worth a read.
