Re: [RE-wrenches] time delay relay

A simple solution that I've used is to utilize an off-the-shelf lighting timer. You can get an inexpensive unit that plugs into an outlet. Take the 120 V AC output and use it to trigger a 120 volt coil relay. Depending on your signal voltage, this may work. You can set delays by using the adj

I did some searches on the list for what folks are doing for off-grid propane generators these days, but all the threads I found were from 5-6 yrs ago, so I was hoping to get some more current info. We're looking for about a 10kw+ propane unit (big derate at altitude), and we run into 2 main probl

Re: [RE-wrenches] Off-grid generator update?

FYI, generally we haven't had cold start issues with propane units, as long as the pipe is sized properly ( as mentioned in another recent post) and the starter battery is kept fully charged. This is based on about 20 years experience in the Rockies with temps below 0, but not 40 below. We don

Re: [RE-wrenches] Off-grid generator update?

For the heater on the intake pipe issue we only run the heater off the generator output to keep the intake breather from icing up while running. You may need to a bit of rewiring. Have you looked at SW products [They bought Hardy Diesel] T - 480 625 5195? They still have 12KW water cooled

Hi Wrenches, We have a particular plan checker who wants us to provide a *lockable* AC disconnect for our inverter output circuit. His particular issue is that he wants the locking mechanism to be installed and on site. Here is a little NEC background info: 2014 NEC 705.22 Disconnect Device

August: You might make the case that a standard load center is externally operable (external as in outside the dead-front) and is lockable (with a lockout kit). Sounds like another renegade building official. Good luck. William [image: Gradient Cap_mini] Lic 773985 millersolar.com

Re: [RE-wrenches] Off-grid generator update?

Does the generator need to feed an inverter /charger input? In other words, does it need to provide AC/60hz? If it can be a DC genset (which is usually easier on the system) check out Polar Power. http://www.polarpower.com/ Roy Rakobitsch NABCEP Certified Small Wind Installer® Certified Advance

Re: [RE-wrenches] 2014 NEC 705.22 disconnect for inverter capable of being locked

So an AC disconnect in the inverter output between the inverter and panel or utility disconnect if required doesn't work for him or her? The locking provision is always in place on a standard AC disconnect. Jesse Dahl NABCEP PV Installation Professional IBEW Local 292 - Electrician Electrical

Re: [RE-wrenches] RE-wrenches Digest, Vol 9, Issue 129

For off-grid generators I have found that the Onan propane RV units like model #HGJAB are a great unit. (Onan is owned by Cummins, same units as Cummins Commercial series I believe) These are only 6500 watt units but they are low RPM, very quiet, fuel efficient, and start great in cold temps. (the
