Load dump charge controllers question?

Sparky

I notice some charge controllers have a dump load feature. so my question is this?

If I have a 200 watt panel going into this type charge controller on a fully charged 100 ah battery, will the charge controller keep dumping the 200 watts to another device?

1........as long as the panel is getting sunlight in the first place.

2........ can this wattage be sent to a SSI-200 Grid Tie Inverter to suppliment the power at my main panel?

Likely not, unless it's 280VDC. Most grid tie inverters need 200+ V to function. Many grid tie strings are wired for 400-500V, to keep the current (amps) to a minimum for less losses. You would have to match that voltage EXACTLY to have the inverter make use of it.

You can use the voltage to run a water heater element.

I understand that at this voltage, a battery has twice the power of one with 12 volts. Ineresting.

It's the difference between "Chronic Underchargeing" and a "Full Charge" You need to supply higher than battery voltage, to the battery, to force the chemical reactions needed to move the lead from solution to plates. To get 12.5V out of the battery, you have to force 14.5V into it, for a prescribed period, allowing enough time for the chemical reactions (charging) to occur.
