So your battery bank is 4 series-connected lead-acid or AGM car batteries ? SW2000 is connected to AC input of Iota charger, DC output of Iota is connected to battery bank, which is also connected to big split-phase inverter ?
Our banks is actually eight 6 volt (400 ah) lead acid batteries wired all in series to get the 48 volts the inverter wants to see.
So Iota is guaranteed not to try to pull too much juice from the SW2000 (which in turn might try to pull too much juice from the Leaf), even if the demand on the battery bank is very high ?
Exactly, the smaller inverter on the Leaf will just pull a steady 800w and dump that amount in to the big bank, if the house is using 500 watts the extra goes in to the batteries and if the house is pulling 1000 watts it uses the 800 (750) watts from the leaf then pulls some from the lead acid battery bank to make up the change. And the surge loads for motor starting or anything else doesn't affect the Leaf in any way.
Why do you have a 120v->240vac step-up transformer if you have a split-phase inverter ?
In this system I don't since we upgraded our main inverter. In our last home I had two 2400 watt inverters but was only 4800 watts at 120 volts so all my critical loads needed to be 120 vac, that was when I had the transformer in place in front of the well pump.
