inverter installation

[Tom Warner]

If you wait a few days Ernie I will take pictures of my Heart
installation in the rear of my PT40. I have just been finishing a
couple of little things on the 1982 Fc before the new owner takes it.

yes you can use the same battery bank on the PT40 to connect the
Heart to. But I plan to add some more batteries in the rear just have
not decided how to do it yet.

As for installing it "right". Of course there is many ways to
install an inverter/charger but if you want it to do what the
designers intended then you should not rebalance the loads on the
existing load center but install a new Square D sub panel. Makes for
a very neat easily installed look. As for installing the Heart in
place of the old chargers in a FC model and running 4/0 cable to the
front drivers side compartment please dont do it. There is to large
a voltage drop (should be less then .25 VDC) since the cable run is
over 40 feet when you take both the -positive and negative cable runs
into consideration which is how you calculate the voltage drop. The
ideal installation of course is in a PT where it can be installed in
the old charger compartment with very short cable runs. And I hope
you are installing the Link 1000 with it. The link really gives you
good indications of your alternator output while the engine is
running and the output of the chargers when either the shore power is
connected or the generator is running. It will also give you the
current reading of each individual device in your coach as you turn
it on and off. Real neat for finding problems.

As for using the sensing functions of the Heart (or the Trace)
inverter/chargers if you install the battery cable to the positive
terminal of the shunt you will NOT be reading all of the current flow
thru the batteries and thus all of your readings will be incorrect.
Why would you want to do that after spending well over a $1000 for a
very sophisticated inverter/charger? But of course everyone can
install it like they want.
