3000W Inverter

(See update below Jan 10, 2023 and new update Oct 10, 2023 and new update Nov.22,2023) Nov. 22, 2023 I am so pleased with Giandel 2000w inverter that I purchased a second Giandel pure sine wave inverter for another project. The 2000w inverter continues to work flawlessly. Customer service (Eric) was spectacular....I would rate customer service 6 stars on a 1-5 star scale. I consider the value of a product is based on the product itself AND the customer service department of the company that makes and services the product. Oct 10, 2023 I would still purchase this inverter without any hesitation. It has worked absolutely faultlessly over the last almost 1 year. It can start my refrigerator AND water pump simultaneously without a single problem because of the soft start circuitry. This occurs at least every 2 weeks because of roaming blackouts.....in 3rd world electrical grinds like in the USA and other countries. I use this unit only to to support my refrigerator/freeze and water pump. I am constructing a second battery backup system for other stuff. My system has automatic backup (AC to DC) with Xantrex single circuit automatic transfer switch, available here on Amazon and LVD (low voltage disconnect) with Blue Seas m-LVD. Cons: 1. I am disappointed in the battery cables supplied................They are aluminum with copper coating..................I purchased 100% pure copper tinned Marine Grade cables to replace those with the unit. 2. The remote switch is a pain to install in a panel...........cutting a rectangle...............I just don't understand why the manufacturers don't design a device with a 54mm hole saw cut out??? Is that simply to torture the DIY person like me, who buy their products.....ha, ha, ha ..........a joke? CB The Giandel 2000w pure sine wave inverter started and ran our 10-year-old (old technology…no inverter compressor…Whirlpool, LG, Samsung, Haier) 26 cu ft side-by-side refrigerator/freezer on first start up for 8 hours without a hiccup…. thanks to the soft start circuitry in the Giandel inverter. If you search the reviews and customer Q & A sections you will find many 2000w pure sine wave inverters WILL NOT start a Full-Sized refrigerator despite reporting a “Peak Power Rating of 4000 watts, including the Renogy 2000 w pure sine wave inverter, the best-selling inverter on Amazon. Other brands may run a mini-frig, RV sized refrigerator or off-grid designed refrigerators but few document typical on grid based full sized refrigerator/freezers operation. I bought this inverter for running our refrigerator/freezer/washer-dryer/etc. in the event of a power grid failure. Several of our devices have an extremely high peak starting power requirement and this unit serves the purpose, with its soft start technology without having to purchase a 4000-6000watt pure sine wave inverter. To my knowledge Renogy does not have Soft Start circuitry in their inverters. (Update Jan 10, 2023) We have had multiple problems with the grid. Since the above review we have had 3 prolonged periods of no grid...6, 7 and 8.5 hours. The inverter has performed flawlessly on each occasion powering our full size old technology 26 cu ft side by side freezer/re-frig. with multiple startups, defrost cycles, etc. The fans never turned on and the device was only mildly warm to the touch. Never an alert and always the voltage remained 120-123 volt and 60 Hz. Suggestion to Giandel: 1. Get rid of the triangle security screws…. In order to change the in-board fuses, if needed, you will need a TA30 driver bit (for example Amazon ASIN: B0BBP1X4W8) 2. Allow the ability to have customer set the Low Voltage Battery Disconnect point. I believe the current unchangeable default in 9.6 volts which is way too low for my system. 3. Provide red and black silicon inverter terminal cap covers to reduce the risk of metal objects coming in contact with the terminals 4. Provide at least 3-foot length inverter cables. The cables that came with the unit are at least 1 foot to short for my installation.

I am reviewing this product because of customer service. I have a folding 130W solar panel, 50AH/12V lithium ion battery and a charge controller (1st photo). I charge the battery during the day and "dump" the electricity into a EGO Nexus Power Station which has 3 outlets. Those batteries run my lawnmower, string trimmer, leaf blower, chainsaw, hedge trimmer and leaf blower. When those aren't drained I run the TV and PS4 for most of the day and on rare occasions of grid power failure. This is more for experimentation with off grid solar (we're on our 3rd house with a solar system). One day I had a full battery and hooked up the + cable to the - post and the instant I touched the - cable to the + post there was a large spark and melted the metal (2nd photo). After that the inverter didn't work. I emailed to see if I could fix it at home (the warranty was done because of my moronic error) like maybe fuses or something. Giandel customer service person, Elsa (that made my 4 year old daughter happy), emailed to tell me it did have fuses, what kind, a link to Amazon for ordering and instructions (there was an error in the instructions but I figured it out eventually) on how to replace. All 4 fuses were blown, I replaced them and it is once again working perfectly. It works per specifications. I am going to try to make the connections "idiot proof" by making the + cable and pole connections 1/2 inch and the - cable connector and pole some other dimension. The battery poles are just coarse thread bolts (see 2nd photo again). I haven't figured it out yet but I'll come up with something. This review is for the best customer service I've had with a company, maybe ever. Even though I made the mistake she said "And I will wait for the test result after you replace the fuses. If there is still a problem, please contact us again, we will provide you the warranty service, so please don't worry." Not sure what else to say but a great big thank you because it seems the last few companies I've had to call for customer service makes me feel like I'm going to the dentist (no offense to dentists just not normally my favorite thing to do). Maybe I should floss more.

If I could give Giandel a 6 star review I would. I bought one of these 3000w inverters and it ran well for about 2 weeks, then quit. Amazon sent me a replacement. Installed this new one, turned on the microwave,it ran for 2 seconds then the inverter went into permanent overload. I connected an extension cord from a GFI outlet in the house and connected it to the power line running from inverter to the electrical panel in my RV. Turned on the microwave, ran for 2 seconds, then the GFI tripped. I figured I had a short in the power cord or the Automatic Transfer Switch behind the electrical panel. Dug out the ATS, opened it up and saw a number of burnt wires. It was 19 years old and had been used with an onboard generator, now discarded. I replaced the ATS and ran a new 8/3 power cord from the panel to the inverter. I contacted Giandel and asked if they had repair facilities that I could ship the inverter to and get it repaired at my cost. They answered right away, had me take a video of the OL alarm on the lcd, I included pictures of my installation and the wiring, they said they would look into it. 3 days later I got an email with a tracking number. They sent me another new 3000W inverter, no hassles, no haggling! I double checked the shore power lines and the new inverter line, all appliances worked well, verified with an in-line amp/watt meter. When the new inverter arrived, I installed it, held my breath and turned it on. It is working just like it should ! It ran my microwave, my A/C, ( not at the same time, I am still gunshy), the coffee pot, even a 1500 W electric heater without a problem. Hopefully, I have it all sorted out and with the great customer service from Elsa at Giandel I will enjoy my truck camper out in the boondocks.
