Is this setup enough to power up a blender please?

Hi
I'd ike to use a blender (500 or 600W max) with my 12V lifepo4 200Ah battery, a 1000W inverter and a 100A BMS.
Do you think it will be okay? I'll make sure I use appropriate gauge for cables (something like 6AWG) but my concern is about the peak surge in current when starting the blender. I don't know how to find this value.
If the blender needs more than 1000W when it starts I think I'm screwed, either the bms will die or the inverter will stop everything.
Thanks for your help
 
Also I read an inverter always has double power for the surge, meaning a 1000w inverter should take 2000w at peak so it should be fine.
But my concern now is the bms, can my 100A one take the surge?
 
Thanks and sorry for the confusion. Yes I checked the inverter I'm planing to buy and it's fine it will handle the blender's power surge when starting (it would surprise me a 500W blender surges at 2000W at start :) )
Do you know if a BMS can handle a surge that goes above its spec, for a few seconds while the blender is stabilizing at it's normal power?
 
My BMS went into short-circuit protection when I tried a 700w blender on a 1500w inverter. But I think this is due to me having very conservative settings in the JBD BMS.

I think most BMSs should be able to handle a very short surge. Just check your settings.
 
I'd keep my 6ga fine wire cables from bat to inverter under 4'. Which BMS do you have?

JBD 100A + lifepo4 200AH + 1000W inverter, will it be fine for the 500W blender's current surge? and same for a 600W blender please? thank you

If the inverter was a quality Victron Phoneix unit it’d prob drive the blender, cheap inverters, not so much.

With the proper wiring, breakers, fuses, parameter settings, it's going to be five o'clock somewhere.

If you have a volt or multi-meter, but don't have one of those 100 or 200 amp DC or AC/DC clamp meters. It will be the best $45-85 for troubleshooting issues.

You have BT right. That makes it easy to set parameters and it should handle your load just fine.

Which battery do you have?

Yeah, I have BT. I can't check at the moment what my settings are, but I think my short circuit protection is too low.
I have a 12v 100Ah Lifepo4 battery (DIY).

I have a multimeter that has a clamp, it's for AC current, I'm going to check my blender current with it, that's a good idea. I will be able to do it in a few days only.

Should handle it, but is on the edge.

Any chance the blender has a soft start? 5qt kitchen aid mixer does.

It has 5 positions, I guess the first one doesnt deliver the whole 500w at once, so it should be fine for the bms then :)
