GIANDEL Power Inverter 5000 Watt Pure Sine Wave ETL UL458 Listed Converts 12 V to 120 Vac with Hard Wire Terminals & Push Mount Remote with Big LCD Display for Solar System RV Trucks Camper Boats

(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?CBThe 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 terminals4. 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 was skeptical that the low EMF rating would be significant enough for an extremely electrical sensitive person like myself could use it without symptoms but to my surprise I am able to use if for 30 minutes at a time cooking with my portable induction stove. I really thought the stove would be a bigger issue as well but at medium levels of a 1000w or less it's ok for me to use. At max power and wattage though the emfs reach a little further than I can keep away from and I felt the effects so I don't use mak power anymore and that will have to work.

I originally bought the 1200W inverter to power appliances in my van. It worked pretty well over a few months while using the van. However while using the microwave (rated for 1000W) sometimes the inverter would cut off. This would typically happen when it was warmer outside. I guess the inverter was somewhat at the limit and the temperature would push it over. Interestingly enough it would always run my InstantPot DUO (also rated for 1000W).When back from my trip I reached out to Amazon which referred me to Giandel since the return window was over. While talking to Giandel they recommended to get the 2200W inverter for a 1000W microwave. Apparently microwaves even if rated for 1000W can pull much more at least during the startup.I offered to pay the difference for the new inverter and return the original one. Giandel support agreed and they sent me a new 2200W inverter. They also sent me a return shipping label for the original inverter. I thought this was extremely generous from their side.I installed the new 2200W inverter in the van and the inverter runs the microwave fine without cutting out. We'll see how this fares over time and in warmer climates.Another thing to consider is that the 2200W inverter has a higher standby current (I noticed between 0.8A-2.0A). The 1200W inverter standby current observed was about 0.3A. This was another reason I originally chose the 1200W inverter. When running the actual loads however the 2200W inverter seems to be more efficient and it pulls less amps from the battery (e.g. the microwave was pulling ~115A with the 1200W inverter but it only pulls ~105A with the 2200W one).So there you have it. Make sure you size your inverter properly.A big shout to Elsa and to Giandel for the amazing customer support !

A good solid inverter with great Info screen.

This product lasted till exactly when the warranty ended and no longer. I would like to add it was used very lightly for solar water system and only used to power our water pressure system. Shortly after the warranty expired it stopped outputting power. Would have to leave the unit on for hours before power would start outputting sporadically. Eventually it just stopped all together. The ‘asurion’ insurance through Amazon is a scam. I paid for insurance and been trying to file a claim for months now- every time I get to the last step to get a shipping label- says “sorry something went wrong’ I’ve contacted support and they tell me to ‘keep trying’ well it’s been months now and at this point my paid insurance is about to expire. Just as they wanted. I’ve had this same issue with asurion in the past- I should have known better. I trusted Amazon though. But Amazon literally won’t help me at all. I contacted manufacturer but of course they are a Chinese company and speak broken en English and the only resolution they offered is to buy a “second hand unit” with a 12 month warranty- for 500$. Yeah not going to fall into that trap… just so I can spend more money in 12 months when it breaks? Buyer beware. I got scammed so you don’t have to. Buy a more quality product instead of cheaply made Chinese garbage.
