Interesting. When I used my Induction cooktop, it does not cycle on and off. The induction stove at home does though. Wonder if all frying pans are on full tilt until they get up to temp?
I agree with Jon R, not a conclusive test. Got a space heater? I have one that has settings for 750W and 1400W that would work. Bit far to deliver it to your place though

Jon I think you are right as I hear mine do that and a red light on dial comes on and off in process....
I removed the inverter from truck and one of the two BB batteries and will open up the inverter ... I do notice the neg and pos terminals have a considerable 'wiggly-ness' .... maybe one/both are loose.... will report after opening it up.

All fixed and nice and pretty. 2 BB 100 AH batteries and the 1000 W inverter ( opened it up and the negative terminal was loose) . Back in action... Drained my wife's small e-Bike battery and then charged it up in the camper set up ( it is a 1/3 the size of my ebike other battery that I will also be charging on the road). It took 2 1/2 hours. The battery was essentially empty. So The first shot is (from my shunt app) of well charged house battery bank at around 13.3 V (200 w). photo 2 is the battery spec and #3 is what it took to charge the ebike battery through the 1000 W Renogy Inverter from my 200 W (2) Battle Born battery bank...
Just a note ... my wife's bike is a Propella and it will do 15 very hilly miles up to 35 flat. ( she has a second battery we carry on the back rack just in case). My battery will be charge tested latter but its is a big one and the purpose of this is to be sure the extra BB battery will be reliable to recharge both ebike batteries after a days ride..... I got the feeling it will.

36v by 7 Ah ==> about 12 by 21 Ah
21Ah of 200 Ah ==> about 10%
It looks like your session took about 7-8% of the battery.
I recall on another forum thread indicating greater than 100Ah for fully charged BB battery.
Seems reasonable for non calibrated instruments and ballpark specs
Looks like you are going to have a bunch of fun available.

Thanks Paul. My eBike battery is a monster ... can go 75 miles on it. 50 hilly terrain.... not that I have any plans for such things.. but as a dingy on the camper I am assured I can get fuel for the truck or get to a place to ask for assistance with it. I love a plan B.

Fiddle sticks. I though I was made in the shade. I discovered the negative bolt was loose. After that it seemed to charge the battery. HOWEVER .... I was charging a battery which was only half empty. I tried today with the battery nearly completely drained and the inverter would start out ok for 4 seconds than the overload alarm buzzed for 4 seconds. It started again ...same.... 3 more cycles and then the alarm came on and stayed on. As a reminder I have the 1000w Renogy Inverter. The e-Bike charger is a fast charger 58.8V 3 Amp (see photo) .
I do not currently have the inverter grounded to the camper bus bar..... could that be why it is kicking off?
Sigh.

Rob, what gauge wire do you have feeding that inverter? How long are those wires? I'm thinking the Renogy is turning off because it is detecting too low of an input voltage under load.
And are you sure it is an overload alarm, or is it a low voltage alarm? see page 16 of the manual
