🔌 GIANDEL 4000W Pure Sine Wave Power Inverter - Heavy Duty DC12V to AC120V with 4 AC Outlets, Remote Control, USB Port, and LED Display Review

All hooked up, made sure everything is grounded and all input and output voltages look good and clean. It seemed to work fine at first, but after a few minutes of running it with a 21W device plugged in, it crashed and wouldn't turn on again. None of the fuses are blown. Sounds like a blown internal capacitor or component. Very upset, I really hoped it would last a long time. Sounds like they have to use the best manufacturer. I requested a refund and they sent it back within a week.

The device is quite a good size and heavy. Installed in docking van and connected to transfer switch. Hooked up to four (4) AGM batteries and at almost full load it draws some current! Update - (1/12/2019) - after a few months of use this unit was working flawlessly. We even went camping and just left this unit on. At night it powers my CPAP and electric blanket (on low) all night, and during the day it charges the batteries using solar power, or I run my 2kW generator. I haven't ridden it much

1. Solar indicators do not work even if 1 or 2 panels are in full sun. The panels successfully charge other batteries. The light came on a few days ago and hasn't since. The support team is only available via email and takes many hours to reply, presumably because they work according to Asian time. It's hard to even find contact information.3. Some of the things customer support told me about the device should be IN THE USER MANUAL. Why should I receive information via email that everyone…

A little over a year later, the device stopped working. All the protection that thing talked about is useless! He just died. The touchpad was completely inactive. No buzzers, no warnings, nothing. It is not possible to contact this company by phone. You don't have voicemail. After weeks of trying to contact them via dozens of emails, they wanted me to diagnose the problem myself. Also, I had to pay $60 to ship the defective unit! They will either fix it and ship it back to me or they will send…

I was very happy to find this - a true sine wave inverter in the 2200w range. Just a few years ago this would have been a $500-$600 inverter. The only issue I had was with the power meter: I used a 100w incandescent bulb to see if it worked. The Giandel customer service staff quickly contacted me and showed me that it takes a little over 100 watts to get a reliable reading, and after that the reading is normal. software problem? The output is single ended (120v only) and not split 240 phase…

I used this 2200w Giandel inverter as part of my semi-portable solar system on wheels. I intend to power everything under my outdoor gazebo here in sunny Florida. I am currently using Harbor Freight 100 watt solar panels along with three 12 volt deep cycle marine/car batteries in parallel at 420 reserved amps. This morning it powered my 1200w coffee maker and my 1300w air fryer for lunch (15 minutes prep time) with no issues. never woke up. My batteries, on the other hand, may need some…

Let me first say that I have used several different inverters from different ones, they are unreliable and have almost no quality control. This unit works better than most, actually great when the voltage is above 12.8v, but the low voltage cutoff (as shown on the display) is triggered at 12.5v on the C-pillars. I use four AGM 12V 100Ah batteries in parallel as a power source, so there is a lot of power left over that I can't access because the inverter shuts down. Even the INVERTER display…

Unit purchased = 4000w. Use for RV / 5th wheel. Received via Revain two days after purchase in good condition but remote control is missing. The missing remote control was received three days after support contacted me. Pros: Works according to the review. My plans are to use it for my 5th wheel drive. I received the device and tested it to see if it would hold up before putting it on my fifth wheel. I connected it to four long life 300A AGM batteries using two strands of 4/0 wire for positive…
