Renogy inverter fan noise

[Bertietoo]

We currently have an unbranded Chinese inverter/charger. It's only 1000W, but that's OK for us as it only runs the fridge when not on EHU.
I have in mind to upgrade to Lithium and at the same time upgrade to a Renogy inverter/charger set up.
One problem we have with the current one is that the fan is fairly noisy. It's not helped by the inverter being right behind the head of the bed(on my wife's side!).
So any new inverter would need to be quieter. Has anyone any info of the Renogy inverter's noise output?

Thanks
Steve

I ran a renogy 2000 watt inverter for a couple of years now and never heard the fan running I think it a good bit ok kit.

I don't have a fridge running on the inverter, but I understand that it's common practice to switch it off at night, relying on the insulation on the fridge until the next day.
On a related issue, I keep reading about inverters that only switch on "on demand", such as when the fridge thermostat cuts in. Can anybody point me towards one of these, I'd like to get an idea of the cost?

Renogy fan.
I only ever hear my fan running when it’s under heavy load. EG. When using the microwave.
(Oh, yes you can, using lithium and a correctly sized inverter.)

Fan running with the fridge? Not gonna happen with a 12v fridge.

I’m probably the last person who should give advice.

BUT, go for the biggest battery you can afford. 300w Fogstar as a minimum. The 460 is a brilliant bit of kit, and possibly the 3000w Renogy.
Although, if I was starting over, I’d have the Victron Inverter/charger.
Hope that helps.

It may possibly be common practice, but if so, it is a bad practice. That is how food can get contaminated and food poisoning occurs. If you put a tracking thermometer in a fridge and a freezer you would see what kind of temperature they go up to when switched off - and it is above the recommended ones easily.

Inverters with an ECO mode or AES (AES in this contect means 'Automatic Economy Switch' and NOT 'Auto Energy Selection') will stay in a standby mode and detect if there is a load demand - and if so will turn on to satisfy that demand, then turn off when the demand has gone. Probably all the Victron inverters do this (all the ones I have used/set up do) and using this function is a significant power saving.
