What to do with all that power ? | 11 comments (11 topical, editorial)

"mistake in the control panel".  Not a mistake, but I don't like to use the load terminals to directly feed anything more than a control circuit (relay or optoisolator).
It doesn't take much to fry the LVD part of an 'SS-X with LVD'.  The surge of an inverter can do it before it is even turned on.

I would connect the loads to the battery terminals, or directly to the battery.
The loads shown are OK, but be warned about larger loads or inverters on the LVD terminals.

Some of those coil cords look nice, but are very thin and cause a large voltage loss.  Consider something super-ugly with heavy wires when you start using more power.

Not putting it down.  I like it.  It works, and it's simple.
I like over-kill, such as the 100A/1000A surge switch for a 1.2A panel!

Hi Ghurd,
Thank you for the reply.
I'm such a novice that it took me some google searching to figure out what 'SS-X with LVD' means. Duh!!!
If I connect a load to the battery terminals of the SS, how does it protect the battery from draining too low? (besides monitoring it manually)
At what loads should I worry about overloading the LVD terminal?
Would I notice it if the LVD terminal is damaged? (LED not working for example)
Should I connect a relay to that terminal? If so, how?
Sorry for all the questions, but I'm just barely understanding what I have done so far;)
Thanks,
Arno

P.S. What is the best place to connect a voltmeter (one with a needle) to check the battery charge? Since I get different readings depending where I connect it.

The SS-6 with LVD, the LVD is rated for 6A.  I would want to keep it under 5A.

The LVD is almost an emergency use idea.
Most people don't want their batteries below about 12.4V.  Almost nobody wants them below 12.2V.
The battery is 'dead' at about 11.9V.
The LVD doesn't disconnect the load until 11.5V, so it doesn't protect the battery as much as it seems.
Using the LVD to automatically control a load that often cycles will damage the battery in a short time.

The volt meter would go on the SS-6 battery termminals (will not be too accurate while charging or while loads are on), or have seperate wires down to the battery itself.  
I would put a momentary-contact normally-open switch in the wire (MOM-N.O.), push the button and the meter works.
