That particular inverter is out of stock at the moment, but I am considering getting one when it comes back in stock, at the reduced price of course.
I would like to know, if anybody has one and is using it, how do they like it? Is that power saving mode an actual useful function, and makes a difference. My application for the unit would require that it runs 24/7, that is why I am asking about the power saving mode. I will be attaching the unit to my 100Ah AGM battery, so I am not sure how long the battery lasts with the unit running 24/7.
I will be plugging in my Dell server, WD MyCloud NAS (4 x10TB drives), and a small 5 port Ethernet switch. Not sure how to calculate the watts needed for running those units. I think it should be way less than a 1000W. I think my Dell server box has a 350W power supply, but not sure if that is what it is using at all times. The NAS box, I am not sure what sort of power supply that thing has. As for the Ethernet switch, a good guess would be maybe 30W.

You will get approximately 2 hours assuming 50% DOD. This should be paired with a 200W solar kit for sustainability.

I dug out my kill-a-watt meter, and decided the get some readings for my Dell server box, and my WD MyCloud NAS. Just to reiterate, my Dell server box has a 10TB HD, and the NAS has 4 x 10TB HD.
I took a separate reading, for each one: Dell server box - 23 watts .22 amps WD MyCloud NAS - 35 watts .32 amps
I am trying to figure out, running these two units off of the 1000W inverter, that will be attached to a 100Ah gel battery, at what point does the inverter have to be shutdown or the battery has to start a charge session with a battery charger. My direction with this is to have the 1000W inverter on 24/7. Since I will have a battery charger connected to the battery, which will automatically start up when the battery gets to 12V, wondering if the battery charger is going to be on a lot.
The other thing is the days are getting shorter, more cloudy rainy days, the solar panel array is going to be limited, in how much power it can provide. So, the question is, is it worth getting and setting up a 1000W inverter with these conditions?

Did you say how many panels you have? I looked and I didn't see it.......
To be honest I don't think a 100ah battery will be able to do very much with what your using and a 1000w inverter.......
But that's me.............. Others might look at it differently.........

If I add another 100Ah battery then the problem is, will I have enough sun power to get the batteries fully charged. I think that even if I do not add the inverter, with the existing conditions, I will probably need to add a battery charger solution to get the batteries fully charged anyway.
I have four 100W and two 50W mono panels. Panels are placed in positions where I can capture the most sunlight through out the day, for the array. I decided on the panels being in parallel, because some panels may get shaded and some will have some sunlight.
I am trying to figure out, if I only have to run the battery charger, lets say, maybe 30% of the time, maybe it will be worth the effort, a decent compromise, for the conditions.

I think you have enough panels for 3 maybe 4 more 100ah batteries.............. No problem...........

A 100AH SLA battery yields about 600WH at 50% DOD. You have 500W of panels. Assuming 50% average yield for 4 hours / day = 1000WH. So even with my conservative estimates, you have enough power coming in to charge another battery (tattoo already told you) plus run your servers, which are actually relatively small. And you certainly don't need a 1000W inverter. Remember that the bigger they are, the more power they draw just to stay alive.
I would connect the kill-A-watt to the system as a whole, rather than trying to estimate the sum of individual components. Based on what you have said so far, a 300 - 600 watt inverter would be sufficient.

I noticed that on the back of the 1000W inverter, there is an RJxx comm port, but I did not see any mention anywhere as to how or what it is used for. Is that some kind of mystery item? Also seeing the that Renogy no longer sells any RJxx cables, is the comm port a useless item. I am re-thinking the idea of purchasing this item. Cons - has a possible useless comm port, and it only has one AC outlet. Anybody else notice any faults with this item.

I don't worry about the different ports and such that are on it...... LOL Hell I haven't seen any but I haven't looked.......
I use my Renogy 2000w and a 500w inverters for what they were intended to be used as.............. An Inverter to run my entire cabin and have been doing so flawlessly of 3+ years....... That's all I need them to do is just work.......... And that's what they do very well............
If you don't like it don't buy it..............

I looked at the other 1000W inverter, and it looks like a better deal. It has two AC outlets, 2.1A USB charge port, and the remote port. That is looking like a better deal, for my purposes.
I listed the cons so I could get a reaction from Admin. The only reason I used "faults", is if they do not work or fall short, for my needs.
tattoo, since you have a 2000W inverter, can you give me an idea as to how power hungry the unit is? Not sure if you run the thing 24/7, how much noticeable heat does it put out?

tattoo, since you have a 2000W inverter, can you give me an idea as to how power hungry the unit is? Not sure if you run the thing 24/7, how much noticeable heat does it put out? Yep my 2000w runs 24/7 365 days a year....... I have a fridge and a freezer hooked to it..... When I didn't have the freezer hooked up I ran my entire cabin off of the 500w. The 500w is off as I don't need it at this time but it is in my system so it takes about 20 seconds to go from the 2000w to the 500w if needed.......
I don't remember how much power the 2000w takes idle but it's in the manual......
I can't say I have ever noticed it getting hot. When I had the 500w running my system the fan ran every time the fridge came on but it never got hot....... It was warm to touch but not hot....... Now the 2000w is room temp when you touch it even in the summer......
Unless your going to run a good bit you won't need a 1000w......... I started with my 2000w but figured it was to large for a start up system so that's how I ended up with my 500w............ The 2000w is great for a table saw etc....... Something that is going to use a lot of power.......... A 500w can't take it.....

Now I am curious, how many batteries or battery power do you have connected to the inverter. If you are powering a fridge and a freezer, that has to be using a lot of power, especially if you lose power and both units have to start up.
At the moment my calculations reveal that I will be using about 65W on the inverter, but that is just a starting point. I will have to see how that works and may be will have to add another 100Ah gel battery, in parallel.

I have 6 6v 235ah deep cycle batteries and 12 100w panels...... I also have a few lights, radio etc but that is about it....... The most of what I do is during the day when the panels are producing the most power.....
The other day it was over cast and drizzling rain...... My batteries were at 12.7 by 11:00am..... Now it wasn't heavy over cast but it was cloudy..... So I believe it's set up correctly.....

I have an old Monitor top fridge and it doesn't take much power at all....... And the freezer is a small chest type........ It doesn't use much power either.......
You really have to think through but not dwell on your appliances...............
