750W Solar install on TT
I am attempting to wire a 2800W Inverter/750W PV system onto a 2007 Kodiak 210DB hybrid, capable of shore or generator input. I am posting my basic wiring diagram in the hope that, if I've overlo...

My (limited) understanding is that the MPPT will efficiently step to send maximum amps to 12V bank.
A quality MPPT controler will do three things that are all good.
1)Allow a higher input voltage allowing panels to be in series. This reduces the power lost in what is typically in an RV the longest wire run; and allows for much smaller gauge wire.
2)Not easily understood, and I'm to tired to tonight to try to put it into some analogy. Basically, as the sun changes, and the battery bank voltage changes, the MPPT gets the most energy from the panels into the battery bank as these conditions change.
A PWM controller simply LIMITS the both the solar panel output and battery bank input to regulate the battery voltage; while the MPPT controller maximizes the transfer of solar production into a discharged battery bank.
3)A good MPPT controller will also have multi-stage battery charging that is programmable for the batteries that are attached to the system. A really good one will also have a temperature sensor to attach to the batteries.
The only downside to a quality MPPT controller is cost. But, how much is it worth to get the most out of the monies spent for both the solar and the storage?

More money maybe, but really take a look to see what you get.
Hope this helps.
