LP Generator Auto Start Issues
Hello- I am new to the forum and relatively new to solar/battery systems and LP fuel systems. Currently we have a Honda Eu3000is generator converted to LP gas and is hooked up to a Magnum Energy ME-ARC controller. The generator is used as a backup or supplement to the solar panels and not the sole energy source to charge the batteries. The biggest issue is being able to rely on the auto start function and the generator starting on its own. The generator is hooked up to a 500 gallon LP tank, there is a regulator on the tank and then it is fed to the generator regulators. On the generator there is a small Precimex regulator (similar to a gas grill regulator size) which is plumbed to a Garretson KN regulator which feeds the carburetor. I'm not very familiar with LP fuel systems so why it is setup this way is beyond me. When the controller commands the generator to start you have to manually press the primer button on the regulator in order for it to start while the generator is cranking, if you don't use the primer button it will not attempt to start. It doesn't need much priming either, just a touch of the button and it will start, too much and it floods. Once the generator gets started it runs great with no issues at all. When it was converted it was bench tested using a 20lb grill tank and started on the first try each time but since plumbing it to the 500 gallon tank it needs to be primed. I have a couple pictures of the regulator setup to make it clearer. We've tried eliminating the small regulator, by passing it completely and plumbing into the regulator that is on the side of the house as well, neither allowed it to start that way either. Could the load block need to be adjusted or is there something else not set correctly?
