LiON ME 2000w 24v power supply and solar panel for sale $800.00

[Phulcrum]

I have the unit mentioned above and i'd like to sell it. Nothing wrong with it , I just dont have a 24v vehicle to charge it. I do have the 24v solar panel to charge it and that is part of the sale.

Link to actual product? Depending on the specifics, you may be able to use a 12V/24V power supply to charge it from the vehicle. It can be charged from 120V AC correct?

it draws a lot of power when charging, so an inverter would have to be like 2000w. You can also use upconverters to get to the 36v it wants from solar, but you'd be down to 1 amp if you were starting with a 12v system.

I'm 24v and might be interested. Let me do some reading later this week and get back to you!

Especially nice since the fridge runs off 24v...

This is only the bnt price. I'm listing it on marketplace for 1400.

For AC charging it basically expects to be plugged into a 15A house socket for reference. That's good for 12A continuous so that times 110V and you 1320W. My 1000W inveter in Rathtar won't quite do it but a 1500W should without issue.

Looking at the charging specs, the solar claims 585W MPPT. If you use boost converter to get to 36-60V (that's the range), amperage capability would need to be 10-17A to reach that wattage. I'd suggest going with a 25A boost converter to prevent the converter from browing out.

Did some quick reading. So this inputs 24v but outputs 12v and AC. It only charges from the 24v solar or an AC input? So it could charge in a 24v truck, or with the inverters listed above, or with the provided solar panel?

Interesting! How long have you had it? Any warranty still in effect?

Looks like the ME wants to see 36-60V solar DC.

From the spec sheet for the unit they state that it's AC charge rate is 668W and that it will take 1:23 to charge the battery. This adds up as it should... 668W X 1.383hr = 924Wh (the battery claims a capacity of 922Wh). Likewise for a solar charge system that can source 585W for 1:35hr.
All that said, a 1000W inverter powered by a well charged battery / alternator combo with short heavy gauge battery cables should be able to handle the job, assuming the inverter can really make at least 668W on a continuous basis which might be asking a lot of a 1kW inverter depending on the make and model. Inverter specs, even good ones like Renogy, can sometimes be misleading and often neglect to mention the DC supply current requirements... Realize that a 90% efficient 1000W inverter powered by a 12V source would try to draw 92.6A (1000W / 12 / 0.9) from your truck battery, requiring very short, very heavy gauge cables to minimize voltage drop the due to cable resistance. Even at 13.8V with the alternator charging the battery the inverter would still try to draw about 80.5A. A 10 foot run of 4AWG wire would have a voltage drop of about 0.5 volt at 100A which would amount to a 50W of power loss and this gets worse quickly with longer or smaller wires. The bottom line is that in practice it's a challenge to get maximum power output from inverters.

My 1000W inverter has that heavy gauge wire which got quite warm trying to charge this thing even with the engine running. It's a rather long run though, from the battery to the rear compartment. It could be that I need to go up even higher in gauge to compensate for the length.

I have had it for about 5 months. Used it for a couple of events. It powered 3 fridges for 8 hours with no solar feed at one of them.

It's 2300 new plus the solar is 3-400$ new. These are def used and show minor signs of wear. I would be happy with a smaller ( 1000w) unit for my personal needs. If don't sell this one to the club I'll just hang on to it for events.

It's a 'nice unit' , which coincidentally was my band name high school.

Exactly Frank. And that wire heat is the manifestation of those wasted watts in terms of current times the voltage drop in the wire, bigger wire or shorter lengths is the way to go. In reality though, using an inverter to convert car voltage of 12-14VDC up to 110VAC and then the internal 110VAC charger of the portable power unit to charge its 12V battery is an inherently inefficient process with each step up or down costing you at least 10% in power loss. Charging the power unit directly from DC either from the car battery 12-14V system or solar panel should be far more efficient. Inverters have their place, but I'm not a big fan and tend avoid them where possible.

No doubt Tim, $800 is a sweet deal if you need one of these systems!

I only had the 12V accessory type of outlet, not the anderson type so had to use the inverter. It does look like the inverter would have done it if the cable diameter was larger. It would run for about 15 mins before tripping the breaker so it was on the edge of making it.

If one has the solar and one of these, you can likely setup a nice base camp powering a fridge, lights, etc...
