Predator 1400W Generator for charging batteries on 34 restart.

Those predators are good little generators.

After you have a more permanent mount set up check and see if the fuel cap is the same size as the 2,000 genmax... if so genmax makes a extended run time kit the adds a 3-6 gl tank with built-in fuel pump... no modification to the generator. Just change the fuel cap, hook the fuel line from the the new cap/fuel pump to any boat fuel tank 3 gl or more and plug the pump into the genurator... done... you fuel tank plus a 3gl boat tank will give you 32hrs non stop run time.... just something to think about. This is the kit..

I also have an battery powered APU. But my APU runns through Xantrex 2500 inverter/ 100 amp charger. I also have 2500 watt generator and if I connect it to my inverter - all my 110 volt loads (Dometic 110 volt AC also) will be powered from generator and the batteries start charging.

It works probably 5-8 hours on a fuel tank, but after generator stops it switch to batteries and it enough until the morning.

Love my setup)

 

I have been thinking about adding a couple of these to my system. 12V Ionic Lithium Group 31 | 1800 CCA | LiFePO4 Heavy Duty Diesel Starter Battery
Right now I have 4 AGM starter batteries and 4 AGM for EPU. I understand that these would basically trickle charge the other batteries until they equal out right. So it would be like added 2 more batteries to the system and they have a built in jump start as well. This will most likely be the way I go when I need new batteries for starting. Don't think I would use all 4 Pos for starter incase of cold issues on starting but think it would do fine with 2 and 2 AGM.

 

For $30 more you can buy a pulsar 4000 generator from home depot. And it has a rv hookup.

That's pretty much exactly how I want to set my truck up, but with the open frame 4550. Much longer run time, and will feed the 20A shorepower. Mine will fit nicely underneath my headache rack, down in between the frame rails.

 

downside to open frame is they are LOUD. My 3,500 runs at 59db... that equal to normal conversation.. and runs 12hr

 

something else to consider is run time.. some like the one 4,000w listed run 4.5 hrs at half load (1,600w) before refill. Others like my 3,500 will run 12hrs before refill

also warranty... Harbor freight is the only one that has a REPLACEMENT. If it breaks for any reason (even if you drop it) just walk in to any harbor freight and walk out with a new one in the box in under 1hr. All the others require it to be sent to a shop for repairs... so would you rather drop you trailer a drive to a harbor freight, exchange a bad for new and drive back to your trailer or drive to a shop and drop it off and wait for it to get fixed, the difference is the warranty.

Remember that portable generators were never designed to do the job we need in the environment that we put them in...

 

3500
11 hours at 25%. That's 750 watts. On 2.3 gallons.

4000
4.5 hours at 50%. That's 1600 watts. On 1 gallon. 9 hours on 2 gallons.

Someone mentioned a gas cap with aux tank to add for capacity.

The specs.
3500 peak. 3000 continuous. 212 cc motor. 2.3 gallons. 100 pounds. H20xL22.75xW17.3. Cost $800.

Because of it's bigger motor. It does offer electric start.

4000 peak. 3200 continuous. 145cc motor. 1 gallon. 45 pounds. H17.3xL18.9xW11.4. Cost $480

If the comparison is running time. @25% it's 11 hours to 9 hours. 750 watts to 800 watts.

The only drawback. Is one has to be ordered. But they carry tons of models. Where as the other only carries one brand.

Inventory is easy when it's only one.
