[RE-wrenches] Heart Interface Inverter

[bob ellison]

Try putting a load on the generator (like a 1500 watt hair dryer) before the
Heart kicks on then once it transfers to the loads and starts charging, shut
it off.

It might be finding the voltage or frequency to high for it’s liking.

Plug it directly into the generator of somewhere before the inverter to get
gen power.

For what it's worth, the Fluke is known to mistake harmonics for base
frequency. I would look to borrow for a scope or at least use a cheaper
meter that can accurately report the frequency. Try slowing the generator to
59 Hz to see if the inverter likes it better.

Hello Wrenches,

 

AC charging system specs

Onan Marquis Gold 5500 LP Model 5.5HGJAB119D generator

Heart Interface Freedom 20 Model Inverter Charger (120VAC, 100A charger,
12VDC)

 

I have a new customer who has a used Onan RV generator (as specified above),
working with a Heart Inverter charger (specified above).  When the generator
is started, the Heart inverter kicks on and starts to charge, after about 3
seconds it kicks off, then on, then off and repeats.  The voltage and
frequency of the generator output look good. 120V L-N and 60-62 Hz no load.
The Heart just doesn't seem to like it after it kicks on the charger.
(Sorry, no scopemeter available)

 

What is very interesting is that on the other pole of a transfer switch
connected to the AC input, is a fairly inexpensive gas generator, pull
start, on wheels etc.  This puts out 108VAC at 59-60Hz.  When connected to
this generator the Heart immediately latches in and will continue charging
flawlessly at 100ADC.  For whatever reason, the Heart, doesn't like the
voltage waveform of the Onan generator.  The Fluke 87 multimeter that I was
using to test, was catching some type of transient (frequency reading would
shoot up to 70-100Hz) when the Heart would latch into the Onan.  Other that
that with my simple tools I could see no real difference between these
generators, other that the 108VAC of the gas generator.

 

Any ideas, or known compatibility issues with this equipment?

 

Thanks
