Bob,

You're right. The input is 120 VAC 30 amps to the main breaker. There are "up to" 5 branch AC circuits. One of those is rated at 15amps and feeds the converter. Others feed the HWH and A/C, etc....

The converter "INPUT" is 120VAC and it consumes (at max power) 780 watts. That is 6.5 amps (of 120 AC). to produce the DC power.

The 12 VDC is really a "nominal 13.6 VDC" rated at a maximum of 45 amps which is 612 watts of DC power.

That is divided into 11 DC circuits, each fused with a 15 Amp DC fuse. (those can be changed to higher or lower amperage if the wiring connected to each DC circuit is upgraded or downgraded) ** the maximum is 20 Amps at each circuit**.

The battery charge circuit is a 3 level charging circuit, Boost= 14.4VDC, Absorption=13.6VDC and Float= 13.2VDC. Somewhere I read that the maximum charge amperage is 40 amps, but I can't find that reference now...

There are two "reverse polarity protection fuses" rated at 30 amps. They do not protect any output circuitry, but only serve to protect the 12VDC input from the battery against reverse polarity. They are not connected to the 12 VDC output side of the converter.

Hope this helps more than it confuses......
