Quiet inverters

Santiago - 8-22-2010 at 08:52 AM

1. What is the quietest inverter in the 1500-2000 watt range?
2. Is the only point of the charger part of an inverter/charger so that a generator could be attached to it and the generator will feed the panel and charge the batteries at the same time?

#1
all inverters hum...
the humming gets louder as you increase the load

then they may have a fan for cooling

just keep it in the garage
with the batteries
never in the house

remember once you convert your battery power
to 120v you can run the current along way

#2
yes you are correct
when using the charge feature the fan comes on
more noise

The cheaper the inverter the louder they are! Bob is right, you don't want to be sleeping with them...the inverters...not Bob and Susan. The batteries are the place to go cheap. Better to spend the money on controllers and inverters and grow into them. I used an Outback MX60 controller and Outback inverter with 480 watts of panels and 4 Costco batteries for 5 years. No problem with the controller and 480 watts, and I watched constantly. Couldn't believe I was making electricity! I have added batteries and panels and maxed out the controller at 1600 watts, and that's mostly because Sun Electric was selling those blemished panels so cheap. Great deal....hard to see blemishes and the only thing that see them are the zopolotes. If I need more power I'll wait for the grid....along with Pompano...and Pompano and Bob and Susan will get it long before me!

We bought an Outback Inverter(Big $$) had it just less than 3 years & it blew the transformer. Outback wants almost as much to fix it as a new one---Think NOT! Will think twice about Outback products next time.

Had this similar earlier model installed in the San Felipe house 12 years ago. As far as I know it's still going strong. Trace/Xantrex 1500.

meme could it be that you
let the batteries get too low...:?:

lower batteries make the inverter
work harder...thus fry:O

I use my Honda 2000E when I run my power tools. When I get my small, 120v PV system set up with a 2000 watt inverter/charger, should I plug the generator into the charger and run the tools from the 120v side of the system or just continue to run the tools from the generator? Seems like I would get some charging of the batteries during the time the genset is running but is the constant start-up of the saws and compressors hard on the system?

I have a bit larger system but never use the gen set if the batteries are charged. If I work into the evening and the batteries get below 24.5v I'll run the generator for a short time to pump the up for the drain during the night. If you work early you probably won't need to charge from th generator. And you can always add a panel or two to help too.

It's probably a carryover from when I had a very small system, but when I run the washer, or a tool that I'm going to be using for a while, I plug right into the generator. Hardest part is running the extension cord, and, if you've got one of those 2000's you don't even need an extension cord. I don't like large and fast draws on the batteries and they've never been down to 24.5. As far as using and charging at the same time....I use the tools or I charge the batteries. I think if you have a big generator, more than the Honda's, you could do whatever you want. Someone might be able to explain where I'm wrong, but I think I'll still do it that way.

It depends on how you have your system put together and what quality of eqipment you have. I have my system set up so that I can run my large tools ( table saw, mig welder, metal lathe, band saw, etc, ) off the inverters, and only run the generator for AC on hot nights or to charge batteries after several cloudy days. If you stick with good stuff, like Outback, Midnite solar and some of the newer Xantrex inverters, they can handle the high surges from power tools. Some of the smaller inverters may not like it and might fail. If you use stuff from Harbor freight or similar then stick with your generator to run the power tools.
Hope this helps
