Small Generator question, Subaru

Looking to purchase a Subaru RG3200IS.

In this application it will provide around 500 watts of power to operate an Iota DLS-55 and a smaller 10 amp smart charger. I've tracked the load and the initial draw is around 500 watts and then it drops to around 300 watts.

In the past I ran a Honda eu2000i and then sold it off after around 4k hours.

that was replaced by a Hyundai hy2000si.

Now I am going to the Subaru because of:
5 year warranty
1/4 rated load is around 700 watts, or able to power the charge cycle all in 'economy mode' so I am looking at better gas consumption.

Anyone else have experience with the Subarus?

thanks!

    The original Subaru with Robin diesel prime mover is legendary in its reliability. If you can find a used one in reasonably good condition and/or have the skills to recondition it, it will last almost forever. The current model with the Hatz diesel is infamous for frequent problems and prohibitively expensive repair parts shipped from Germany by slow boat.

    The model you specify uses a gasoline engine and it appears to be close to prime mover quality.
    The CA emission warranty is for 500 operating hours, the highest under the standard, and the maintenance calls for an engine rebuild after 1000 hours if needed.

    I believe that there is a 5 year warranty on the engine. Not so sure about the entire generator.
    When you drill down the specification tree on the Subaru website you are sometimes taken directly to the engine spec pages without warning.

    Re: Small Generator question, Subaru

    right on the home page there is this statement:
    " All Subaru portable generators are EPA and CARB compliant and are backed by a 5-year limited warranty regardless of application."
    I called subaru to verify and the lady I talked to said yes. I mentioned that the generator would be running for around 12 hours a day 365 a year. She said fine.

    I'll see if I can find any specifics on the exact wording of the warranty.

    I called to verify because our local small engine shop is listed as a dealer & repair shop. the owner is less than thrilled by the five year warranty claim since he knows the kind of use I am planning.

    Re: Small Generator question, Subaru

    The EPA and CARB compliance is AFAIK limited to 500 operating hours without needing a rebuild, since that is the longest period that the law allows/requires.
    If Subaru chooses to warranty any repairs needed to maintain compliance beyond that 500 hour limit, I guess that is their privilege, but I do not think that they are allowed to claim over 500 hour compliance in their advertising.
    Also, the warranty coverage does not apply to normal scheduled maintenance items. As I recall, an engine rebuild is "scheduled maintenance" at either 500 or 1000 hours "if needed", so I do not think that a rebuild would be covered by the warranty if, for example, you run 3 hours a day for a year.
    If the engine blows up before the scheduled rebuild, or after a successful rebuild and before the next scheduled one, then you might have a warranty claim.

    I tend to agree with the dealer's feelings on the issue.

    thanks inetdog.
    I'll be ordering the Gen this week. After talking with Subaru and the Local small engine shop again I am optimistic.

    At this location we put on about 4k hours a year. If anyone is interested I'll post updates.

    I'll check with the service center to see what 'in shop work' they recommend to maintain the warranty status.

    My decision was based on warranty claims, local service center, fuel consumption and price. We'll see how it works out.

    Re: Small Generator question, Subaru

    You said you'll use 300-500 watts depending on the charge cycle, but the genset is at 25% of its rating at 700 watts. Diesels need to mostly run with at least a 40% load to prevent multiple problems, but you'll be running yours much less.

    With roughly a 4800 watt load each day (400 * 12) and 12 hour run time (lots of fuel), this sounds like the perfect situation for a PV installation.
