In this video, we finally find the root cause of what was causing this Aims Inverter to fail unexpectedly and blow 300A fuses in our 12V BigBattery 170Ah Power Block. Needless to say, we ended up just having to replace a major key component on this inverters internals.

Really enjoyed the diagnostic process. I've had the 2500 watt unit for over a year. I've been happy with it. Mine will fail under a very specific set of circumstances. Usually when the whole unit is hot (camping in summer, so the whole RV is hot), and I run the Keurig coffee machine for 3 or more cycles. I can usually get the first two cups of coffee made, but the third one will fail and the Aims inverter will reset. Rarely, it will cause the 300a fuse to trip (fused line is the cable from the battery).

Thanks so much for your work. My inverter exhibited the same symptoms after 3 weeks of light usage. Sungold gave me the run around on warranty to point that I just dropped the issue. Sungold and aims are the same inverter. Can't wait to try this and hopefully get my inverter back

I am glad you fixed it. The craziness in my opinion is one of the CPU pins is not connected and once you press on it it'll connect and reboots. If you have a magnifier you could detect the issue in the old board.

Good Job! I used to work at Electric Car Parts Company. They sale and service Sigineer inverters. Pretty much the same inverter. I replaced quite a few upper and lower boards and the fans. A pretty cheap fix. People would call saying they blew up there inverter, and we would just replace the board and they were good to go. Its a pretty easy fix just be careful with the connections and take lots of pictures for help remembering where all the connections go.

By the way, I have the 3KW version of that inverter, it says I need to leave at least 12 inches of clearance around it for air flow. Maybe you can put a fan in the rack to help it out?

Seems that is usually the fix new board or mosfets. would have been nice to see the other side in close up but it may be a cracked solder joint/trace

I saw some people replaced that chip and it works.

back to a sweet outback vfx3548.. got 4 running on several projects for years. 24/7 replaced a dead aims with one 5years ago..

Fun stuff testing ! Warranty!

Great ! Problems on that old board was done away with when you changed the board for a new one. It's ashame that standard policy voided your warranty though. AIMS is a good inverter and you got a back-up board in case the same problem reoccur in the future.

12V/2.5A no-load current is too big for 12V inverter. You can try buying an old APC UPS. It uses iron transformer and works very durable. Moreover it is very cheap. In my country, a 2200VA-1980W APC UPS is only ~100USD.

Oh dang,,Well yeah wouldn't have thought of the CPU onboard would be loose. Just use a Soldering Heat station to reheat and resolder.

@andrewfrey4940 2 жыл бұрын

You may be overloading or underloading the transfer switch in the inverter and will cause the inline fuse off the battery to blow. This can be verified by checking voltage and current on the input/output or a Kw meter. long extension cords to the AC input will cause voltage drops if it cant support the 15A load also, its not recommended to use a different manufactures remote as they are proprietary and cause damage to the CPU on the control PCB.

Where did you get the replacement board?

What is that diode device you use to protect the power supply? Can you recommend a brand and part number?

Hi, 3000 watt full sinus inverter fault light is on. When the inverter is turned on, a relay tripping sound is heard, then the fault light is on, what do you think could be the problem?

I suspect you just have a bad solder joint for the microcontroller. If you have a hot-air solder works station you could reflow the microcontroller and fix the issue.

from 10.29 Im finally hearing some information..Dont mean to be cranky but we want to learn, not the story of your issues. Thanks for sharing your discovery.
