I don't understand why I won't have 6kw charging capacity (2.4 from chargemaster + 3.6 from Mass Combi #2) when utilizing 50hz - what am I missing?
Thanks for your input.

OK, sorry. Your comments have made me look more closely at the drawing, and I actually think what you have is pretty messed up. Here are comments:
- I though the black and red cricuits coming out of each inverter were the two outputs from the inverters and were how you are separating 50/60hz equipment
from 60hz only equipment
. Now I see the note that inverter 1 is for 60hz gear
, and inverter 2 is for 50/60 gear
. So I guess I don't understand what the red and black are, and the switches that you show internal to each inverter.
- Inverter 2 isn't going to behave as you expect. If you feed it 50hz power, it will ignore it. It will only use the input power if it meets it's criteria for acceptable 60hz power. So it will always be inverting on 50hz power, and never charging and never passing through 50hz to the loads. I think this is very different from what you are expecting.
- If you want the inverter 2 loads to get 50hz shore power
when available, and inverter power otherwise, then you will need an external bypass relay.
- If you want more charging from 50hz power, you need more pure chargers - the inverters will only charge off 60hz.
- As drawn, there is really no difference between your 50hz and 60hz switch positions. In both cases the charger is always powered off shore plug
1. Inverter 1 is disconnected from shore power
in the 50hz position, but it would always ignore it anyway. And inverter 2 is always connected to shore plug
2, but will always ignore it when 50hz. So those two switch positions accomplish nothing.
- In the gen switch position, you are not powering the charger. You might as well put it to work when the gen is running.
