[RE-wrenches] Wood boiler ignition issue

[Darryl Thayer]

I am puzzled because I have used and found the Magnum to start loads that other equally sized inverters could not start.  I wonder if the hot surface ignitor is not acting like a resistor but somehow non linear.  For the washer dryer the wave form was being distorted by the load and interfering with the controls?  I have started a two HP pump with a single Magnum, but I never looked at the wave shape.

In the case of the Splendide washer/dryer (see link in my previous post), it was definably the Magnum Energy inverter. I could not start that load (no pun). Since then we have tested several inverters with these washers and all work fine except for the Magnum. I must say that, other than this one fault, the Magnum has been an exceptional, US made inverter and I heartily recommend them.

Kristopher,
I have experienced this as well, but have no solution to advise. My
    last direct experience with this was about four years ago, when we
    installed a system using a Magnum 4448 inverter in a home system in
    which a high-efficiency electronically-controlled hydronic boiler
    was also installed at the same time. The particular boiler proved
    unable to start up reliably on the inverter, but would run reliably
    off of a generator. Initially we assumed that the problem was due to
    incorrect wiring by the heating contractor (the AC input line and
    neutral had been reversed). After this was corrected the problem
    persisted. Before we could dig deeper the contractor changed out the
    boiler to an equivalent model of a different brand. The problem went
    away.

You may end up having to either change the inverter or change the
    boiler. Magnum's tech support showed some interest in pursuing this,
    even attempting to duplicate the problem, but we never got that far.
    You might wish to contact them about this - it's a legitimate
    problem.

On a related note - has anyone had any issues with powerline-carrier
    lighting controls run off of a Radian? We haven't installed
    equipment yet, so have no way to test until then. We're supplying
    uninterruptible power to an upscale residential observatory that
    will have this type of lighting control. We have cautioned the GC
    that there's a possibility of incompatibility, and no database of
    collected data out there, and we don't assume liability for
    incompatibilities. But it sure would be nice to know if anyone else
    has seen issues. I don't yet have a lighting brand.

Thank you,
Allan

Esteemed wrenches,
>I am assisting in troubleshooting a stand alone system with three stacked Magnum 4448 PAE inverters.  The electric ignition of LP for the wood boiler will not fire from inverter power.  As soon as we fire up the generator, the boiler ignites.  Has anyone seen this before?  Is there a solution?  The boiler is a Central Boiler E-Classic 2400.
