Since I don't know anything about inverters except that I need one... I have to ask Is there really much of a difference between these and other budget inverters. Quality/longevity, standby power consumsion, efficiently?



 
There's some good YouTube videos of inverters bursting into flames being used at wattages less than rated, so I'd say yes.

I'm not familiar with the ones you posted. I went with a UL478 rating and use the Samulex PST series.

I have three inverters; two by Samulex and one by Victron' and both the manual specs are fairly accurate for consumption.

A lot of it has to do with continuous usage towards rated capacity and how often its turned on.
 
After many hours of research I finally pulled the trigger and got the Voltworks 1500 watt inverter. So far all I have done with it is test it via direct connection to my truck battery.

Keep in mind that these 1500 watt inverters can pull 125 amps or slightly more, so any battery you hook up to them needs to have a BMS rated 150 amps or more. Ideally, it would have a 200a BMS.

No idea about the GoWise but I have a Giandel and had worked flawlessly for the past 3 years. Will has also done a video on inverters and said good things about the Giandel. The only thing I would say is just check that the cables to the battery are adequate for the current and install the appropriate size fuse to protect the cables.

All these inverters will have standby current draw and I haven‘t spent the time to measure mine although I should. I simply switch mine off when not needed as it has a remote switch.

To back up what Tim Tim said, I also have a Giandel 2000W (slavishly following Will's design) that has been operating 24/7 for over a year now running a chest freezer. Standby consumption according to my shunt is 8W. Happy to buy another should this one fail (does have a 2 year warranty, though how easy this would be to access remains to be seen)

Based on your research, what were the deciding factors in purchasing the Voltworks 1500 inverter?

I am on the edge of deciding by Giandel exactly to operate a small freezer and a fridge-freezer (total running power of 220W). How big of a solar you have to run them?

Napkin math? 220w * $HowEverManyHoursItRuns = total Wh.
Total Wh * $HowManyDaysWithoutSun = Battery size
Battery Size / 5hrs = Array Size.

Again, napkin math.

Also, heard good things about Giandel, but their fancy SCC/Inverter combo unit is horrible from my experience with a few of them.

thanks - I know the energy draw of my fridges because i measured them directly - I was wondering what is the solar array Planecrazy had in practice to cover the freezer's load. Just to know what actually worked.
I know it's a personal choice but I personally don't like the idea of AIOs, A charger is a charger, I would like to see what it does and replace the charger only when I succeed to fry it somehow. Also, if I find some more cash to throw up more panels on a different roof I can connect them via another charger, which would probably a more complicated deal with AIO. What do you think?
 
If you're not wanting to get the grid power involved then yes, it's a very simple system. An SCC, a battery, and the inverter are all you need. Where AIO's really come in handy is when you want not only a hefty sized SCC + decent size inverter + hefty AC charger + UPS auto transfer switch. Once you start buying all those components separately it gets to be more expensive than an AIO.

But, like I said, your system is pretty simple so I wouldn't recommend the AIO route.

Adding a second charger and panel array is actually pretty simple, just ignore the existing array and plug it in as if it was your only array. The two SCC's will work independently of each other and not care that the other array is on there.
 
Can you go into a bit more detail about your application, and what you intend to power? What's your reasoning for deciding on making it a 12V system?

BTW, the Samlex PST that Chrissky mentioned is an excellent choice. It has a total harmonic distortion (TDH) level <3%. The 24V version has NEMA sockets, but can also be hard-wired directly into a main electrical panel.

I just bought an inverter too. You'll go nuts looking through Amazon and reading reviews and comparing prices. For every good review on an inverter, you'll find a negative one that cancels it out and leaves you back at square one. One review will say it ran their 1000 watt microwave, and the next review for the same inverter will say their 800 watt microwave shut the inverter down. Best thing to do is find one at the power you think you need, in the price range you're looking for, with some positive reviews, and maybe some that mention what you're trying to run and just pull the trigger. At some point it's like ripping off a bandaid...just hit the buy it button.
 
I've had a Giandel 2200 watt unit running for about 6 months,so far so good.
Only drawback is that it creates RFI on the HF bands (amateur radio).
