Pulling more than 1C from that single battery is going limit the maximum output. I'm looking at a 12v or 24v split AC unit. On high power they pull 40Amps. Low power 20-25 Amps. I plan to cover every inch of my roof with solar (1400-1500 watts of solar) and 600Ah of Lifepo4 batteries. The solar panels will add some shade to the roof which should help to keep the van a bit cooler. Half the split and the pump are going under the van behind the rear axle. In theory the solar panels should allow me to run the AC on low power from lunchtime 1pm ish and top up the 600Ah battery bank fully to let me run the AC for a few hours during the night. Plus run a fridge and some low power 12v LED lights.

Just be careful. Those budget 100Ah batteries often don't have BMS's that do well at 100A continuous discharge and its not unheard of for the mosfets to easy bake oven themselves. I was actually surprised yours ran in the hundredteens for an extended period of time but sometimes the 100A BMS's wont shut off until 150A. The general rule of thumb is 100Ah per 1000W of inverting power since the vast majority of those cells have a continuous rating of 1C and a 30 second burst of 2C.There are some cells with 3C and 5C ratings but its usually the 20Ah to 50Ah cells I see with those ratings. 941wh out of 1280wh is quite good at 1C/1.2C. An industry standard 0.2C test will probably yield over 1300wh. What did you pay for that battery? I'm guessing its one of the $300 to $350 Amazon specials? Edit: oh thats not the Jita...man $500 they are taxing. You could almost get a 200Ah with a 200A BMS for that much. I see them for $600 and some change.

900wh consumed in about an hour, so you're pushing an average of nearly 100 amps, with spikes well above that number. Yes, with that inverter compressor, you "can" run it from a 100AH battery and a 12v inverter, but you'd be way better off to have a 24 or 48 volt battery, with the same or higher capacity.

If my solar power without a battery stays high enough, can I directly connect the panels to a charge controller, and the charge controller to pure sine inverter (with a fuse in line too)? Then just expect the A/C to run for as long as I have enough direct sunlight? I can't currently afford a large battery setup, and I'm concerned doing something like this would overheat a battery (or being lithium, catch fire- I don't trust them or safety mechanisms inside.) Would it run? And the charge controller keep the output to inverter stable? Or would maybe 2 or 4 batts to run at 24v or 48v solve my overheating concerns? I doubt I could afford that but would be good to know! Thanks!!

No it is not possible. All inverters are very sensitive electronic devices that convert DC energy to AC energy output. The solar panels output varies according to the light intensity, and the charge controllers in turn takes this variable voltage and charges your batteries.

How how many hours were you able to run it like this
@nomadbrad503 Жыл бұрын
About 1 hour. Basically you would need a 100ah battery for every hour you want to run it
@sanwomashi175110 ай бұрын
1kW from 100 Ah (but only Li battery) about 1h so 0,5kW - 2h

Is there any maximun load for the battery?
@nomadbrad503 Жыл бұрын
Yes, the battery has a 100amp maximum bms. It should shut down at 100 amps which is why I was surprised to see this one run over 100 amps.

@@manueljuarez2941 look at the data sheet for your air conditioner. It will have a watt rating. Say it’s 1200 watts. That means the unit consumes 1200 watts per hour on full blast. Then multiply that number by how many hours you want it to cool. If you want it to run from 7pm to 8am that’s 13 hours. 1200 x 13 = 15,600 watt hours, that’s how much battery you need. During the day you should be running off solar so battery bank is for night time

The info you give is if your air conditioner was running full blast all night. Fortunately, in a van or bus, it will not be running full blast constantly. It will throttle down when you get to the desired temp thus using much less power. I feel that your statement that you would need 800 ah to run an ac all night is erroneous.
@nomadbrad503 Жыл бұрын
I lived in this van with this air conditioner all summer in Texas. It ran full blast all day, then throttled down a bit at night but still ran 24/7. keep in mind that your solar panels have to be able to generate enough power to run the air conditioner full blast all day, but then also recharge your battery bank in preparation for the nights demand. You loose full sun exposure by 7pm then don’t see full sun again until 9am. That’s 14 hours without full sun to charge your system. This 100ah battery ran for under an hour....and you also have other devices using power..refrigerator, cooking devices, lighting and so on. I feel my estimate is actually quite conservative
