If I was serious about wanting to install an inverter connected to the HV bus, I'd talk to Tony Williams at QuickChargePower. He might be willing to do such an install alongside a Jdemo install. DC Quick Charging would be a useful thing to have if you're going to run your battery down using power tools on a regular basis.

So I can find them later . . .

ABSOPULSE’s CSH 2K-3U7, 2kVA output, 250-600vdc input, 26 lbs.

Adelser A037050, 120vac 18A (2200W nominal) output, 250-450vdc input

Eltek Bravo ECI 380V/3kVA Inverter, 200-400vdc input, 2500 W / 3000 VA output, 10 lbs.

eIQ Energy DA16K, 320-420vdc input, 16kw output, 6 lbs.

None appear to be plain COTS and no pricing available online, all require custom quotes.

I have a lot of experience with this. I built the T-Rex range extending trailer as a dual use device. Its a standalone unit that I can use to power my car, power my house or take it to a cabin for the weekend. Lots of uses.

I just finished building T-Rex V2 that is a camper on top of a battery. That version includes a 3000 watt dc to ac adapter. Perfect for running power tools in the forest with no power around for miles. As long as I leave myself enough range to get home, I could go into a forest, cut it down and leave a month later. haha

You would need an inverter that can handle HV in. There arent many. I found one locally from a wind installation company.

Yes your car would need to be on in ready mode if you planned on tapping the battery in the car. Its the easiest and best way. When it is on the car will maintain the temp of the battery. If you were CAN savvy you could possibly figure out what the car needs to see in order to close the battery contactors but I think that is a long hard battle that you would lose.

The best place to tap into the battery is at the junction box at the battery itself. However if you have Jdemo, you wont have any room because thats where QCP taps into it. They then bring it to their junction box under the hood.

I could help you if you need anything.

We have developed a High Voltage junction box for these types of applications (aux batteries, inverters, etc).

Can you share the model of your HVDC inverter?

I have a Princeton Power DRI-10. It has some quirks I am working out but it does work quite well. I have videos of it on my YouTube channel and more coming soon. YouTube.com/jimbo69ny

@davewill

Where did you get that tray you mounted your 100A breaker?

I'm considering getting a jdemo. If so, I think I will ask Tony if he can wire something to get access to the pack.

Nothing I saw on your website yet. When can we see specs, buy? I have the HI car with Jdemo, you may remember.
I'd like to use 120V tools like a 13A lawn mower, 15A chain saw & snowthrower (230V 22A being considered for conversion from gas).

Directly to 12V battery, 1200W (2400W peak) inverter with load meter - works great on 12A lawn mower (showing 440W). There's 2 zones beyond extension cord length so I use the RAV4EV instead of gas tractor!
Currently mounted on top of plastic, hood partly or fully open. Only used when stationary so install/remove as needed. How important is it to have a ground to earth from inverter if tools (lawn mower has ground plug, chainsaw does not) are double insulated?
Is there a good place to tap into the 12V DC so inverter is mounted inside?
