My apologies. I see this recommendation comes from Magnum. The suggestion is still valid when other brands are involved and parallel capacitors are considered.

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.

Start with 10uF.

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!---------- Shine On!Kris Schmid Legacy Solar, LLC 864 Clam Falls Trail Frederic, WI 54837 715-653-4295 www.legacysolar.com NABCEP Certified PV Installer BSEE -----Inline Attachment Follows----- _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org -----Inline Attachment Follows----- _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
