Ampeak 2000 Watt Pure Sine Wave Power Inverter! How Much Can It Handle

[@subcoolHVAC]

I’ve had the same model inverter installed in my Promaster van since September 2022. I use mainly for charging drill and vacuum pump batteries while driving between jobs. No issues

[@johnblystone8781]

One thought about the 0 AWG battery cables and the fuse. If they pass through the fire wall of the van, the main fuse should be located very close to the battery. Otherwise, there is the risk of fire. Good job. Your van is really set up nice!!!

[@Bryan-Hensley]

Unless you have multiple batteries, that size cable won't even melt the insulation when shorted to ground. I used to work for a stereo shop and saw diy installs where the cable would melt to the exhaust. However you will need 4 automotive batteries to even think about getting full power out of my 3,800 watt inverter..

Inverters are a Great idea for a contractor like you. Thanks for the video. 👍🙏

[@Cobracommander1986]

Great Review, because of you I will be ordering one of those inverters 🙂. YU

[@BryanI00]

I really love that new van and wrap. That looks so sharp!

[@Bryan-Hensley]

I've got a 3,800 watt inverter in mine. It will run 110v recovery machine, vac pump, microwave, and portable AC.

[@TomLawson05]

Great install very handy happy Father’s Day to you and riley

[@HVACGUY]

Thanks! You too!

[@OnusBones]

My apologies if you know this stuff already. You'll want to get AGM deep-cycle batteries to run your inverter, especially without the engine running. A typical "car battery" is meant to be discharged maybe to 95% while starting an engine, before being topped off again. It has many plates for the high current needed, but they are very thin, and will erode away if deep-cycled. Deep-cycle batteries have much thicker plates, and AGM (absorptive glass matrix) holds those plates in fiberglass so they are much less likely to crumble to the bottoms of their cells, AND they are more vibration-resistant. Another option would be to use a LiFePO4 battery for your inverter; this would be separate from your starting battery. For a 2000W inverter, make sure the one you get has a 200A BMS (many are just 100A). Note that this battery type should not be charged when below 32F, and many have low-temperature protection to prevent that, and/or a heater to warm the battery so it can be charged.

[@jthonn]

Marine batteries are deep cycle, I have used many back in the day shrimping. They will hold a charge longer and if they go dead, last longer than a regular battery between charges. So yep I agree with you on that.

[@Bryan-Hensley]

I do fine with 3 automotive batteries. But I don't do any long run times with the inverter. It's usually a maximum of 10 minutes. If I do high power pulls for extended time, I'll run the engine which has 150 amp alternator that puts out 80 percent idling.

[@Wayman_Simmang]

Very Nice!! Good install too!

[@jthonn]

Man that is nice, and a nice install. Down the road you may want to do a dual battery hookup, just because it may come in handy on a construction site and for storms.

[@bamatractor]

I do need one of those!

[@Bob.W.]

If you are only going to use an ANL fuse instead of a Class T, it would be safer to put an additional MRBF fuse right at the battery. That would give more protection against a direct short. 1/0 wire will safely carry 170 amps at 90degC rating in a wire assembly, and even more in free air. I used 1/0 for my Xantrex 2000. Technically maximun amp draw to size wires and fuses is calculated at the maximum continuous output of the inverter, in this case 2000 watts divided by the lowest inverter voltage before cutoff, usually 10.5 volts on a 12 volt system, divided by the inverter efficiency, usually 90%, times 1.25. This equals about 265 amps. Most don't wire their systems that heavily. However, 1/0 THHN-2 will do 260 amps in free air and 105degC welding cable or battery cable will exceed that. My take is that 1/0 protected by a 250 amp fuse will do. And yes this whole post is anal. 😂

[@zaneenaz4962]

The battery is critical to suppling an inverter for 2kW or greater. As you mentioned they really need 2 x 100Ahr batteries in parallel to deliver max power.

[@Eddy63]

Nice product and nice demo

[@harrydickson4575]

Very cool 👍👍👍

[@billybrown1979]

hey do they make the sawcat circular still have not saw one. that has good strong power. good work and be bless and safe.

[@notyoung]

Considering that the saw needs several times that 13 amps on startup, the inverter has very good surge capability (motor-driven devices typically need 3 to 7 times their running current during startup). Because the inverter is not 100% efficient, you need to adjust your math. At best, the inverter is 85% efficient, possibly with an area (maybe below 800 watts?) where is is 90% efficient. For simple math, I'll use 85% efficient. 2000 watts / 12 volts = 166.67 amps BUT: you need to include efficiency. 166.67 amps / 0.85 (85%) = 196 amps. You'll need at least a 200 amp fuse. That 150 amp fuse will get you 150 * 12 = 1800 watts (on the input of the inverter) * 0.85 (efficiency) = 1530 watts output. To prevent being stranded with a dead battery, I'd suggest adding a true deep cycle battery NOT a "Marine / Deep Cycle" from the auto parts store but a true deep cycle battery that can provide several hundred charge / discharge cycles to 50% or greater discharge. You'll need to read the datasheet for any battery of interest and check the chart which shows depth of discharge (DOD) versus number of cycles. You'll need to determine how long you'll be using battery power for AC and how much AC you'll be using. A Kill-A-Watt meter ($35, amazon, home center) will tell you how much running power each device (vacuum pump, battery charger) uses and, if you leave the Kill-A-Watt meter in place for a full cycle of use or charging, you'll know how many kilowatt hours were used. The kilowatt hours used in a typical vacuum pulldown plus a battery charge or two might be the basis for determining how big your auxiliary battery needs to be (amp hours - not CA or CCA but AH). Interstate Battery has some batteries in the DCM series (DC Mobility for wheelchairs and the like). A 110AH battery is probably in the $200+ range and you might need more than one. You will also find better (and more expensive) AGM batteries from Rolls, Surrette, Trojan and others. Remember that you could also run an extension cord to the truck to use that power for your fridge or a small window A/C during a power outage ;-) If you're interested, I can put a spreadsheet for determining how much battery power is needed to provide how much AC power for how long - it only has about two dozen variables to be filled in but that's because it's very thorough in determining how long your devices will run on XXX battery capacity. I created the spreadsheet as I was exploring solar power - noting big, just a "Wait until daylight" backup system so I'm mot outside in a thunderstorn to get a generator started during a power outage or shoveling 7" of snow in the dark at 30F to get to that generator. My interest is having fridge, furnace and limited lighting for 8-12 hours (the "until daylight") but it works anywhere you're trying to produce your own AC power from batteries. My current backup system is configured for charging from solar power or a grid-powered charged (good option while I'm recovering from spinal fusion surgery - I don't have to go out and clean the solar panels ;-)

[@terryh8421]

Hope you have a speedy recovery!

[@Bryan-Hensley]

You'd need a soft start AC for that inverter

[@anio6865]

Do i have to keep it plugged in to use it ?

[@publicmail2]

Nice inverter but, the not pure ones, had high failure rate and don't last, they put these out for cheapest made and they fail early. That said let's see what happens over time, at least no money out, maybe they corrected in the pure unit. Also check draw with milliamp in line with nothing connected and unit off, the non pure sines where drawing 180ma and will kill your battery over time. Good luck.

[@Bryan-Hensley]

I've had a cheap one for around 25 years. Use it at least 3 times per week. I've got another cheap one that's 3,800 watt that I've used for at least 6 years on about 120 camping trips

[@carl_h]

it will run a small window AC unit.

It might.

[@MannyFontes1968]

Hey Curtis, I've been meaning to ask you, how do you like your Xterra? I have a first gen 2000 and it's been a work horse for me over the years, ever since 2014.

[@HVACGUY]

I like it. 2006. Never had any problems with it.

[@karellodewijks4971]

👍👍😊😊

[@JohnSmith-ug5ci]

Just some information. First you did not mention the output of your alternator. You should not pull more than 75%, max load, of an alternator output for any length of time if you want it to last. 50% would be even better. The reason is heat. The alternator will overheat especially at idle. So, if you have a 130 amp alternator you should not pull more than around 95 amps @ 12v nominal which would be around 1150 watts. Also I would suggest a separate battery for your application and that battery should be a lithium. If you use lithium, it would mean that you would need a special charge controller to limit how much it could draw from the alternator at one time so as not to damage the alternator since lithium batteries have a very low resistance and can over tax the alternator. So, you really should have a starter battery and a separate battery for your inverter. This way you save your alternator, never have to worry about starting the truck to charge your tools, and never have to worry about the truck starting. Also you will shorten the life of a lead acid battery by using it like you are now. Victron or EcoFlow should have what you would need. Just some suggestions.

Printed right on the face, "Output: AC 105V~125V, 60Hz." WTF? Why on earth would ANYONE even connect something that is said to put out 105V? I would put that POS right back in the box, and return it. I don't think I would want this guy working on my A/C for that matter either, as he should know better. If I had 105V anywhere on my property the power co would be on speed dial. Great for electric space heaters, but will prematurely destroy anything else. Sure, just let the Amperes roll!! Very dangerous equipment, and by design makes it even worse.
