I don’t know how that would matter… though I recall my Tesla charger complains that there is no ground when I plug it in to a Jackery 1500. I rigged up a jumped wire to short the Neutral to Ground at the plug to the inverter and it is happy after that. However, I don’t know why that would lead to a “short circuit” error.
Note that some of those watt meters may not observe a short duration spike properly, so if you record a spike, you have a spike. But not recording one doesn’t mean one doesn’t exists. My freezer (full sized chest freezer) overloads the EB70 sometime but not all the time, but the watt meter never or records a max voltage over 400W, when it runs it only draws 100W.
Hi there! Do you prefer the heat of your 12 volt blankets or the Brookstone AC blanket? Does the AC draw considerably more power? I have a truck camper setup and looking to purchase a heated blanket as opposed to the dangerous propane heaters. Thanks in advance!
Have you considered running a lower power draw blanket? I will occasionally run a Stalwart 12v 50w 8amp blanket off my eb70. Using any sogen for heat generation will suck the power from your unit, so consider running low wattage devices. I can only run a 200w personal heater for about 3 hours from the eb70 but a 50w blanket will keep me warm most of the night. Also keep in mind that using the AC pure signwave inverter will also have an inverter use power draw, in addition to your device.
