GIANDEL Pure Sine Wave Power Inverter 2200Watt ETL UL458 Listed DC 12V to 120 Vac with 20 Amps Hardwire Blocks & 15FT Wired Remote for RVs Truck Boat Off Grid Solar Emergency【3 YRS Warranty】

Runs my big 15A table saw in my detached shop but, you need a big battery aray to run anything else in conjunction. 4 12V 100ah LifePo4 batteries would run the saw, but my desktop computer would shut down. I added another 4 batteries for a total of 800ah and this sucker runs everything. It's rated @ 17.4 amps continuously and yes it does, but you better have a BIG battery array and BIG DC cables to support what it's capable of. Fans kick on when it's pressed hard as they should. The remote on/switch works fine, but uses semi-proprietary connectors meaning phone style RJ 9, four conductor terminations. Not an issue for me as I have that stuff laying around as a former Telecom System engineer, I extended it to 50 ft with no problems. Dump the supplied DC cables and make or buy some good 2 AWG high strand count (welding) cables and crimp them with a hydraulic crimper. For the price, it's an astounding inverter, but you have to enough power and associated cable to make it work to its peak. Don't expect any programmability or communication of any sort, just screw it to the wall with BIG DC cables and it just does it's thing. The LED display does tell you watts out, volts in and it just rotates between the two every few seconds. It will give you errors as well, but I've never run into one. It does have a screw terminal AC out, but I've not had a chance to use it.

I had a much more reputable brand of inverter that never worked and ruined many trips over 2 years. I decided to try this cheap Chinese model and just get it for only half of its rated wattage. So I never use it past 900 watts even though it's rated for much much more. I think this might be the key to using these things. Just go overboard on the size and wattage and it will be reliable. This worked flawlessly unlike the Renogy

After a lot of research, I selected the PS-2200KAR primarily to provide clean AC power in my RV, and also as a backup power source for my house during outages -- the trailer sits on an RV pad by my garage. We always boondock (i.e., no shore power) when camping. This inverter was incorporated into our trailer's solar power system: 800 watts of rooftop solar into an Epever (6415AN) MPPT controller to charge two 12v SOK 206AH batteries (in parallel) powering the inverter which, in turn, outputs AC to a TS-30 automatic transfer switch to power all AC circuits in the trailer. While camping the inverter can easily run our microwave and rooftop soft-start air conditioner (although not both at the same time). I have run the air conditioner for more than an hour with no issues. When towing, we also can now run our refrigerator on AC instead of propane. The inverter, batteries, and solar charger are located under a dinette seat (see photo), so I installed three PC fans (two for air intake, one for exhaust) to keep everything running cool; the fans are controlled by a digital thermostat. This system has seen heavy use and has been running flawlessly for the past 10 months. When the trailer is parked at home, I run a heavy gauge extension cord from one of its AC outlets to our house's generator input box which connects to a 10-circuit manual transfer switch. Now, when PGE has one of its frequent power outages, I can immediately switch on house circuits to run off of the trailer's batteries/inverter. In this mode, the inverter has powered our house for hours, including the refrigerator, microwave, HVAC gas furnace/fan, WIFI router, and all the lights (LEDs) throughout our home. Now, when the power goes out, I only have to drag out and connect my portable generator if the outage lasts for more than 4-5 hours. I highly recommend this inverter!

I bought this to help during black outs. I live in a small rural town in a RV trailer and was looking to provide the ability of using AC powered devices when AC shore power was absent, typically either camping or during power outages. Since I am still working on solar and wind power upgrades to my trailer, this inverter was perfect for my needs.It arrived pretty quickly given that the pandemic has caused all kinds of shipping issues. Packaging was well done and not overly large. When I opened the box I was pleased with the dimensions and weight of the inverter. Yes I knew the dimensions, but I am very visually minded. It came with a very small instruction booklet, a warranty card, positive and negative leads for hooping directly to a battery terminal and a remote power switch. Installation was simple. Powers all kinds of items that fall under 2000watts without issue. It claims to have overload ability to 4000watts, but I havent’ been able to prove that out. It barely handles 2200 watts. I imagine its a spike that it can handle for a very brief instant, so I am not very disappointed. I have learned to not take specs to seriously, because it is easy to be fooled with the propaganda of advertising. I was looking for a 2000 wat inverter and this one handles it perfectly. When the fans run, it isn’t overly loud and I made sure to follow the instructions about grooving it some space to keep cool and to minimize dust.One word of cautionary advice, make sure to wire the earth/chassis ground to either earth or chassis even if you have the negative lead connected to battery ground, it won’t work otherwise. I inadvertently connected that earth ground to the negative terminal of my battery bank and it wouldn’’t turned on. Tracing my connections and making voltage measurements solved that issue. Also keep the distance away from the battery as short as possible. If you need more distance, beef up the size of the wire, not length, mind you, but gauge. This inverter can pull heavy amperage when under load and wires pushing to high of average will heat up and can burn.This inverter seems nicely made, feels like quality engineered and designed. It looks good and is easy to operate. It runs all my devices that I use in my trailer and my electronics seem to work just fine. I have not used the soft start function yet, but it is nice to know it has it. Now, only use and time will tell if it remains working properly, but so far so good. I will periodically update as my experiences deepen.

Held off for a season to give a solid run. No issues at all and works great
