inverters

I researched and Renology had excellent right up/reviews; and I've got a solar panel but no invertor.
As far as I can tell, so far anyway. There doesn’t seem anything wrong with the product . Apart from dire instruction booklet. Not forgetting those rubbish cables. Please don’t use them. Jeff is happy with 35mm on his 2000w inverter, and I’ve used 50mm with my 3000w. And for goodness sake, use an appropriate fuse..

When it comes to inverters, go thick!
I used my 2400W inverter (on the Multiplus 12/3000) and I found even the 50mm cables got quite warm and changed to 70mm - and this was a run of only around 750mm long from battery bank to device.
(I'm using the 35mm cable that Victron supplied with my current Multiplus 12/1600 (which is a 1350W inverter) and that is fine, but they do supply decent cable (it is actually marked "Welding Cable", which is ideal for using with an Inverter)).

Yeah mine are welding cables as well David .
 
Please be careful when fitting the Renogy inverter. My 3000w came with woefully undersized cables, and an instruction manual not showing the necessity of an inline fuse.
I was just thinking about that as I scrolled down the discussion.

To start up a microwave, you are looking at about 1500watts from the inverter. To get that, you'll be putting nearer 1800 watts into the inverter.

At that sort of load, even a well charged battery bank will drop to 12v or less, so you are looking at a current of a hundred and fifty amps or more.

You really can't afford much voltage drop in the cable, so 25mm2 would be the bare minimum, preferably 35mm2 or even 50mm2 if the cable run is long.

And this is not really a suitable load for lithium batteries.

Not sure about the fuse. Does your starter motor have a fuse in its circuit? Generally the point of a fuse is to protect the cables from overheating. In this case, the cables ought to be able to cope with whatever the batteries can deliver.
