I have a multiplus 48/3000 that has worked ok for the past 18 months. However in the past few weeks it keeps shutting down due to overload but no overload/short has occurred.
Upon resetting the inverter makes a strange noise and throws another overload fault, even with no load. It finally resets and works ok for a few days before occurring again.
Hello
I just plugged in my new Multiplus 48V/5000VA/70-100, (battery SOC=86) and after about 3-4 hours of flawless operation, the inverter started to hum loudly and then shut down after a few minutes. It does not matter whether the inverter load is 30W or 700W or 0W.
The warning is: "Inverter overload" (red LED overload remains on until reset)
what could be the problem?
Hi @johnp
Sorry to hear about this, overload issues can be hard to find / fix. if you are sure upon restarting with no AC output wiring connected to the inverter, so it's not an external wiring or load issue, then it's best to contact your distributor for repair of the unit.
can someone from victron answer this please?
Have you physically disconnected the ac output wires to verify the fault is in the inverter?
yep, even with no ac load it sometimes throws an overload fault, but give it a minute or 2 it restarts fine and can be ok for 1 day or 1 week
"even with no ac load"
No load?
What about the rest of the ac wiring? A pinched, crushed or kinked cable could intermittently fault. Creepy crawly's also cause mischief.
everything downstream of the inverter has been checked - appliances/wiring etc
Hello, you are notre thé only one concernés. We have exactly thé dame issue with pour multiplus 3000\70. Except that now, it s stucked on overload. But before it was like yours : somentimes everithing normal, and 5 minits or 2 days after, overload. We shut down AC IN and AC OUT, un ordre to sée if it was thé disjoncteur, but overload remaind. We checked thé components, everything looked okay. If you find thé solution, we will be very interested.
Hi @Fine
This sounds like a defect, please contact your distributor for repair.
Thank you DANIEL for jour quick ansver. Our stuff is under guarantee, but thé professional who indtalled it is unfortunatly dead ans ils industry under liquidation. Do you Knox what tout do un that case? Thank you.
Hi @Fine
That's unfortunate!
best to contact your nearest distributor / installer, or ask Victron sales in your country who to contact.
Can the regulator ne thé cause of thé overload?
