Deal Details
Amazon [amazon.com] has the Newly Released Genmax GM10500XiT Tri Fuel Inverter Generator in stock.

Use coupon code: 0510500XIT for $70 off. Not huge but nice for a newly released unit.

I posted this model in a discussion on another thread and thought this deal deserved it's own post.

Newly Released Genmax GM10500XiT open frame inverter generator.
Features:
10500 Peak Watt Power
2-wire auto start technology. (One of the first units with this feature)
CO Sensor/Alarm
120v, DC, 30A and 50A outputs
Gasoline, Liquid Propane or Natural Gas
LP, NG hoses and Auto Stop-Start wire supplied with unit
Quick connect connections for LP/NG included

The 2-wire functionality is what really intrigues me about his unit as my end goal is to have a battery backup system (Ecoflow, Anker, Pecron or EG4) that can be charged via the generator in an extended power outage situation. The 2-wire can be connected to the system to automatically start the generator when the batteries get drained to a certain point. I sent my ideas on this setup to Genmax and one of the engineers sent me an email with info on this unit. Seems to be ahead of some of the other manufacturers but guessing others will be bringing this to the table with upcoming units.

Did you get the running dB (noise) rating?

Yes, Someone on YouTube did the test from 23 ft away. (His standard test)
His results were:

GM10500XiT- Open Frame
Low Idle around 72 db's
High Idle around 75 db's

yeah that's not impressive for an inverter.

Just as noisy as the Firman tri fuel from Costco, though much lower THD, but 2-3x the price.

Interested in the auto/start/stop based on battery backup. Wish it was more universal. If it works as advertised, would be the ideal setup.

The Firman's product page claims 74dB but it doesn't say at what distance this was measured. It does however say that this was at 1/4 load. That's key because the higher the load of the louder it gets.

I believe the Furman you are referring to is a traditional generator. This one is an inverter generator, which will be a big reason for the price difference. Also features like auto start that are not offered on the Firman.

The main advantage is the "clean" power provided by the inverter. Steady power that will not damage some of the modern electronics out there. Traditional (non-inverter) generators are considered to have "dirty" power and could damage electronics. There is plenty of info on this on the internet. If you are going to use a traditional generator, an addition of something like the EG4 Chargeverter is a great product to use. Basically, it cleans up the power supply for you.

The Chargeverter is about $500, so yes, it would still be cheaper to add the Chargeverter to the Firman... it's up to you if you want to go through all the extra connections.

I don't think this is out of line for an open frame, which is the main reason for the noise. Not necessarily the inverter. There are a lot of enclosed generators that are inverters, and this enclosure obviously is what drastically reduces the db's.

If noise is a big concern, the current GM11000iETC deal at Sam's Club is a great option. I'm debating between the open-frame GM10500XiT and the one at Sam's now for myself as I live in a neighborhood.

Yah, traditional vs inverter is a biggie. Besides getting 'cleaner' power out, you also get significantly better fuel efficiency. Quieter too, but that's largely due to a closed frame and running at lower RPMs at partial load.

If I had space for this I'd be convincing the GF we need to spend the $. Keep in mind the derate for LP and NG as well as tank/piping sizes. It recommends 20LB LP but that will NOT support the genny at full load, especially in cold weather. (look up LP vaporization rates if you're curious) So if this is a winter backup for you, expect to need 100# or more of LP tanks to run at full load for any significant time. Similar for NG - a half inch 'grill line' at the end of a long pipe is likely to starve the genny and now allow full power. Note: these are just physical limitations and not anything wrong with the actual generator.

Just googled Chargerverter - they only charges batteries. You still need a battery bank and inverter to output clean 120/240 AC so cost-wise it's much more expensive. If you're looking for a standby solution that's primarily battery/solar with genny backup to that it's a good solution and avoids anything but the chargerverter seeing the dirty power. Presumably it's built to handle that so won't suffer.

typical range for open frame inverter is 65 to 70db, so 73 is not great. 3db is double the sound pressure though not double the perceived loudness
