What is AMMPS generators

We had MEP-003 10kw
then we had MEP-803A 10kw
we now have MEP-1040 10kw

Advanced Medium Mobile Power Sources represent the third generation of Department of Defense military standard generators. AMMPS are replacing second generation Tactical Quiet Generators, which have a 25 year old design, and providing significant operational improvements that greatly decrease the logistics footprint on the battlefield. The current family of AMMPS consists of five versions: the 5 kW, 10kW, 15kW, 30kW, 60kW generators. The AMMPS family:

• Delivers fleet weighted average of 21% improved fuel efficiency over legacy systems
• Increases reliability (750 hours mean time between failure), maintainability, and transportability
• Reduces infrared signature and noise (less than 70 decibels at seven meters)
• Provides 52% commonality of parts across all sizes of AMMPS
• Incorporates military ruggedized commercial components
• Minimizes weight by 10% over previous generation, as well as minimizes size;
• Improves maintenance intervals (500 hours for 5 kW, 10kW, and 15kW; 750 hours for the 30kW and 60kW)
• Reduces electromagnetic interference; electromagnetic interference protected
• Improves sustainability; operates at rated loads in all military environments
• Is capable of starting and operating on common fuels (diesel/JP-8 ) in extreme climatic and tactical military environments
• Meets Environmental Protection Agency Tier IV Interim Compliance
• Includes built-in diagnostics/prognostics for troubleshooting
• Features automatic paralleling and synchronization; simple two button parallel

Some of the models use a PMA with an inverter instead of a brusheless alternator. This allows the engine to run a variable speeds based on load. More like the MEP831a.

None of the AMMPS units have a PMA or Inverter
The 5, 10 and 15 kW's use a Cummins generator and the 30's and 60's use a Marathon generator.

Thats a bummer. The development info suggested the smaller units would be PMA/inverter based.

I didn't get to see inside the 10kw unit so I was still going on second hand info.

We had MEP-002 5kw
then we had MEP-802A 5kw
we now have MEP-1030 5kw

Sounds good, but let me say, Iv been off grid 23 years since I retired, I got 57 thousand hours out of a 22 kw Mitsubishi powered gen set, only changed a water pump. Pulled engine for a rebuild was in great shape still, probably didn't have to, was still running well. Run a tier 4, 33 kw John deere diesel as my secondary, Has 3000 hrs ,alresdy had to change the fuel control solenoid, $ 700.00 , only last 1.2 years. Deere starts well but smokes a white cloud large enough to hide A C-5 (aircraft) for 3 to 5 minuets on most winter starts . Picked up a 3 kw onan powered Mep 016 , really will easily push 5 kw , now that ive changed all the carb and fuel pump, fuel lies ect runs well , but don't think its going to rivial the mitsu

That is a very impressive hour log, what brand is that plant with the mitsubishi engine?

Also, does that tier4 Deere take DEF or does it have an exhaust catylist?

The money line in OP info "Environmental Protection Agency Tier IV Interim Compliance".

IE: the EPA runs the DOD when the wackos run the gov't.

Tier 4 interim compliance is not necessarily that complicated. But that only gets you to 2012, I believe. It is the tier 4 full compliance after that where you see more annoying add ons like DEF or catalytic exhaust with burn cycle.

This speaking from my experience with small (30-60 HP) diesel machines I have in my business. I repowered a skid steer with a Mitsubishi S4S that was sold to me new and cheep because it past 2012 mark without being installed in a new machine. It is the last of the mechanically injected, no DEF or afterburn motors I'm ever likely to acquire new. My 2015 mini skid has a 37 HP Yanmar, and it has a catalytic exhaust with burn cycle. It has not been an issue so far, but ****, that is one complicated engine compartment, I do not look forward to working on it.

Howdy,

A lot of it comes down to the horsepower rating of the engine. Not every horsepower rating is under tier 4 compliance.

That MEP 1040 is a real nice looking unit. I've only ever seen one and this is it. https://www.youtube.com/watch?v=X6JG1TDbTkc I don't think we'll see another one for a along time. I hope I'm wrong
