Hello I was wondering how long you can leave those ACS running with those two batteries I bought the same setup with the two batteries and want to use the AC for camping in our tent
A small portable AC unit (5000btu or smaller) usually runs about 2 hours for me on a 12.8v 100ah LiFePO4 battery. Hope that helps. That will also vary on the temperature where it is running.
Good lord is the inverter fan that loud or is that the A/C units?
If you mean the part when it first starts up, then yes. It kicks on full speed when it starts and then drops down. The larger wattage inverters like that pretty much all sound the same.
Was the test with (2) 50ah or 100ah batteries? I am eyeing up this inverter due to your review and was considering (1) 200ah battery.
It was (2) 100ah batteries. 4000 watts of power at 12.8 volts is 312.5 amps and these batteries can't output that much alone. Even 2 of them was probably too little, but it's what I had at the time. These are rated at 100 amps continuous and can peak out for a short time to 150 amps. If you are not going to push it to the 4000 watts very much, you might be able to get away with a 200ah battery, but just know the amp rating and what that battery can handle. Most 200ah batteries are rated at 150 amps continuous which would be around 2000 watts.
@@SeidelRanchReviews Appreciate it. I think I am going to go with some thicker cables, the ones that come with it look eh at best. 🤪
So how many battery s do you recommend running with this inverter
@@jimmyp7082 I would suggest enough batteries to output 400 amps. Most 100ah LiFePO4 batteries put out 100amps, so 4 would be a good start.
And how long would this unit last running? Thinking about using one of these for a dog grooming trailer to not have to deal with a generator anymore. Would need to power and RV AC, a plow dryer or two at about 1250x2.
None of the Chinese made high frequency, transformerless inverters on today's market including this unit last very long when powering high inductance loads like full sized refrigerators, large power tools Portable AC units or large microwave ovens. The reason for this is that they are of a high frequency, transformerless design and the cheap Chinese manufactured MOSFETs and capacitors used in these units cannot take repeated exposures to high surge loads. Without an iron core, copper wound transformer to absorb the back EMF and high surge demands of these high inductance loads, typically after a couple of year's worth of use, these expensive solar generators can become a non-repairable brick.
You might be able to start and run some high surge loads when this solar generator is new but every time you fire up or shut down that inductive load, you're shortening the life of the MOSFETs and capacitors in this inverter. They also run much hotter than low frequency, transformer based inverters which makes the low cost, off spec, Chinese made components such as capacitors, diodes, resistors and ICs that are used in these cheap solar generators, far more prone to early failure.
This is especially true regarding the amount of electro-mechanical wear on solar generator’s low cost capacitors. Inverters rely heavily on capacitors to provide a smooth power output at varying levels of current; however the electrolytic capacitors that are used in these solar generators have a limited lifespan and age much faster than dry components. Capacitors are also extremely sensitive to the high temperatures found in these inverters. Capacitor electrolytes evaporate faster at higher temperatures which can reduce the life of these components.
Another major consideration with these high frequency, transformer free solar generators is safety. All it takes is for the AC output monitoring circuitry to fail and one of their MOSFETs in the inverter's H-Bridge circuit to short to ground, and these high frequency inverters can send dangerous, high voltage, high amperage DC current straight to your connected AC loads which will not only damage most AC appliances but can also set those AC appliances on fire.
Another consideration is that the vast majority of these solar generators are non-repairable. After the warranty runs out, most consumers will not be able to afford to ship these units back to the manufacturer in China to have them repaired. And at a typical shop rate of $125 per hour, here in the US, with no schematic and limited parts availability, it won't make economic sense to even attempt to repair one of these units. Once the FETs have fried and have taken the inverter's PCB with it, (And trust me, sooner rather than later, they will fry.) they basically become a brick. And finally and third consideration is the fact that many.
A far better alternative is to invest a little more money and purchase a hybrid, low frequency, transformer based inverter charger and build your own "real" off grid system. Low frequency transformer based inverters last far, far longer and can easily power high surge loads without being damaged. That's why the big name brand inverter manufacturers like Schneider Electric, Outback Power, Sigineer Power, Victron Energy and others, all use a low frequency topology in their offerings. I know this to be true because I've spent the last 24 years repairing inverters. High frequency solar generators/inverters simply don't last when powering inductive loads.
Which brands are you recommending that are not made in China?
Magnum Energy, Schneider Electric, or Outback Power.@@SeidelRanchReviews
