Some inverters don't like inductive loads. Check the PFC with the A/C on with a PF meter.

Thanks for uploading your experience with this inverter. I have two 100AH batteries from Redodo paired with a Kreiger 2000W PSW inverter I got last October. It hasn't seen any substantial use at all. It has only been used to charge some power tool batteries so the unit is basically on stand by in case of a power outage emergencies and we need to run some AC or small heater and medical equipment. I went o charge up some batteries last week and it failed to turn on and it just died. I packed it up to send it in for repair or replacement warranty and paid $60 to ship it and insured it for the purchase price of $300. I can't believe the Kreiger just crapped out after not even being run on any big loads at all smh. I was looking at the Redodo unit but after watching this and it chirping like that, it's made me 2nd guess it buying it now.

It’s because AC units have bad power factors due to being the inductive load and you are using a 2000 watt High Frequency inverter. HF inverters work well with resistive loads, but they do not handle inductive loads well. To fix, either get a larger high wattage HF frequency inverter, say about 3000 watts. Or switch to a Low frequency inverter around 2000 to 3000 watts.

I suspect this aircon is one of those midea inverter jobs, similar to their in window units. If anything the unit would appear as a harmonic capacitive load to the inverter but it probably has some type of power factor correction in it. Even if it is a line driven compressor it will again likely have power factor correction via a capacitor.

The display showed the battery voltage dipping below 11V. Their 1000W inverter has low voltage protection at 10V. Perhaps the voltage was intermittently dropping below the loa voltage threshold causing the chirping. Could be a battery issue instead of an inverter issue. As far as the internal cables, copper wires actually have a very high capacity, it is just that the insulation has limits. Active cooling from the fans should take care of that, but it does turn those wires into little heaters which will reduce the efficiency at higher loads. I would like to see companies use variable-speed fans. For many loads just a slow fan would provide enough cooling while keeping noise levels low. Instead, inverter fans typically are either fully on or off. That leads to inverters running without the fan for a few minutes with 10 to 15 second bursts of a loud fan noise. They should do better. I would also like to see inverters incorporate heatpipe technology with cases designed for heat dissipation, thus reducing the need for fans. Combine that with variable-speed fans and inverters would be nice and quiet. Though the fan isn't overly loud, the noise becomes annoying after a while. Appreciate the review.

This inverter is nothing more than a rebranded inverter sold on Amazon under various brand. I have a 1500w from "Luborn". If you search "PrtnrTek" you will see the exact same inverter. My 1500w has been actually very steady. I ran an air fryer and that sucker will run ~1500w. I did run it for close to 10 mins so your 2000w unit is probably defective. I also had this inverter running a full size fridge 24/7 and I had no problem.

I'm wondering if the pure sign wave craps out or gets a little funky looking under the high load of the AC and creates some kind of weird feedback the Inverter doesn't like. You don't need a pure sign wave to run the Heat gun or the Blower so the "Cricket" was behaving.

I think the voltage standard in the US is 120 volts. If I had gotten that inverter set for 110, I'd return it. Remember, the brand name means nothing. Just about all the Chinese stuff is made by just a few manufacturers and slap a label on it.

Any inverter that won’t output a steady 115V is garbage… 120 should be the goal. Most routinely drop below 110V, yours showed 103V at one point. Most likely the meager pair of #8 conductors is heating up, and drastically limiting current from the battery.

Another very informative video. It seems like a decent price for that inverter. I have 3 of the Redodo mini batterries which I have hooked in series for my 36v trolling motor. They work great for that application. I have an Amped Outdoors bluetooth battery monitor installed, with the series configuration, to help monitor the state of charge. With all the products that Redodo has come out with so far, I wonder if they have thought about making a bluetooth battery shunt/monitor? I did inquire with them about the possibility of a marine starting battery as well. It would be nice to replace my current AGM starting/house battery with lithium. I do know there are several other options to fill that need, but it would be nice to have all the same brand if possible...🤞😎

A lot of people have been bringing up the PF of the aircon (ie stating it is a heavy inductive load). Any chance of the model # of the aircon so we can look up what design it is, line / inverter operated compressor and see if there is any PFC in the unit? A kill-a-watt type plug in power meter will usually tell you the power factor, so you can report the PF at different cooling settings.

@@BradCagleNo official documentation about PFC but I have found reports around 0.85. Specs says 1.2kW (about 10A) peak in cooling mode. It should be draw around 12A with that PF. The inverter should be good for 16A. From the description the aircon does have harmonic issues and that would increase the short term current but it should still be within the capabilities of the inverter without it sounding an alarm. All of this is educated guesses since there is no official documentation about this in the user's manual. Someone with a power analyser would be able to tell straight away. A wattmeter probably won't reveal the details of harmonic draw but it would indicate approximate PF.

I think the inverters without a true ground seem to have problems with certain loads. A guy was telling me they kinda need a earth ground for refrence so they can build their signwave consistently at different load levels.

@retrozmachine1189 Жыл бұрын

No, that's not true. No connection to the earth we walk on is needed at all. It wouldn't surprise me at all if this Re-dodo inverter is just another cheap piece of junk (sorry folks, that's how it rolls) and is hitting its actual continuous rating. The 2000W is probably some BS such as 'peak rating' for 20mS. How can it be that the front panel is not showing any alarms when the unit is doing that weird beep? Simple. The front panel display is usually, not always!, just usually completely unrelated to the control circuitry. It's just there as a window for you to look through to see how the inverter is allegedly performing. What the control board in the inverter (usually the smarts are on a separate vertical daughter board) sees and reacts to can be completely different. Of course, this could just be a 'faulty' unit.

@kickgas7171 10 ай бұрын

Yea, it seems to run everything perfectly fine when it's new, but give it a few months of running inductive loads and I guarantee you this low cost, high frequency, transformerless inverter will become a brick and can even damage your appliances by passing high voltage, high amperage, DC current to your loads. High frequency, output transformer free inverters are not designed to run inductive loads like microwave ovens, large power tools, portable AC units or motors. You may be able to start and run some of these loads when this unit is new, but every time you do, you're damaging the cheap Chinese made MOSFETs and capacitors in these inverters. I've spent the past 23 years in the inverter repair industry and can tell you from experience that no high frequency inverter exists on the market will last more than a year when exposed to high inductance loads. If you want an inverter that's going to last 8 tob10 years+, then spend some more money and invest in a low frequency, transformer based inverter.

The beeper is likely driven by the PWM card seen at 1:51, that vertical daughterboard next to the heatsink. What is shown on the front panel will very likely have nothing to do with what the PWM card is getting up to. The AC voltage will probably be monitored by the front panel directly with a resistor divider and the watts computed using that in combination with perhaps a CT/shunt on the live AC wire or by the shunt on the H bridge that the PWM card uses to tell if something is going wrong. It is often possible to disconnect the front panel and have the inverter continue to function completely normally in all respects including protection (of course don't do this if you don't understand the thing fully).

No, when the power is converted to AC, 15 amps will give you 1800 Watts at 120 v AC. For 12 volts DC to supply the power up to the inverter, higher amperage is required. That's why large wire and more than 100 amps BMS is needed to support up to 2000 watts.
