HI All, I’ve got a new project wanting a 22-25kw single phase 120/240vac water cooled propane sound attenuated generator for an off grid situation. I’m not going to be With AGS activation. I”ve been looking at the Kohler 24 RCL ( meets all the above criteria) but I’m checking to see if I c

Jay, I’ve had really good luck with the Cummins RS22. In fact it’s the only propane generator I will use unless it’s for a small system, then I specify Honda ’s with a propane conversion from GenConnect. Half a dozen RS22’s with enclosures and maybe a dozen without, placed in buildings. No probl

Check to see if it has a 120 vac requirement to float the battery. The 20 kw one I have has a big electrical drain David On Mon, Apr 9, 2018 at 11:50 AM jay wrote: > HI All, > > I’ve got a new project wanting a 22-25kw single phase 120/240vac water > cooled propane sound attenuated generator for

They do have a battery charger that requires a 120V circuit, and it does draw more than one would like. I run a circuit over and install a tiny battery tender rather than use the factory charger. With a good starter battery and a weekly exercise cycle of thirty minutes, I have found that my indo

If it's going in a cold climate, the Cummins RS generators absolutely require a coolant heater which is a significant AC load. Otherwise, they don't require any AC power but they do need their battery to remain charged. For this reason, they do come with an integrated charger, but if you have a

Yes, the Cummins technician that commissions our generators insists that locations with consistent low’s below 15F require the coolant heater. All but two of my installs(outdoor) have omitted connecting the heater, and have seen some brief sub-0 temperatures but generally average mid-30s. One of

Hi all. This unit will be in a warm climate so no problems there. Are you all saying the build in AC/shore power charger is extremely inefficient? Jay > On Apr 9, 2018, at 1:46 PM, Michael Morningstar > wrote: > > Yes, the Cummins technician that commissions our generators insists tha

  We've had gen sets at 11,000 ft and way below zero start on propane for decades without using the block or water heaters. Ridiculous electric heating loads on the other hand are a very bad idea off grid.  Just make sure the propane supply lines are large enough so the pressure regulator doesn

Ray, That's not going to work for the Cummins RS water-cooled generators without some hacking. The water cooled models do use an antifreeze mixture so they can withstand temperatures down to -50°F without a heater, but they have a circuit that prevents the generator from even trying to start if
