[RE-wrenches] Wood boiler ignition issue

[Exeltech]

Adding a capacitor of that size across the inverter's output may cause problems
for the inverter.  Much depends on how the inverter's output voltage control loop
is designed, among other things.

Before making any changes of this nature, I highly suggest contacting the inverter
manufacturer to ask them what issues (if any) may result from such a modification.

In turn, they may request from you more detail about nature of the load the inverter
will be powering.  Is it reactive (and if so, what's the power factor)?  Linear or non-linear?
And so forth....  It would be helpful to if you have this information available before you
call them.

Hi Kris,  A solution to try would be to add a motor run capacitor across the line at the boiler.  10uF-20uf range may improve the crossover distortion enough to allow the boiler ignitor to operate properly. Start with 10uF.

Subject: [RE-wrenches] Wood boiler ignition issue  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.Thanks in advance!----------
