Clarity on Grid Passthrough
Hi, who can assist with clarifying some questions regarding the passthrough current on the Sunsynk 50kw inverter?
I'd like to know, is the max passthrough current of 200amps, 200a per phase, or 200a in total across all 3?
Also, is the 200a additional to the +-75a max the inverter can output?
Reason I'm asking is, our building needs more than 75a to run (long term, with additional aircons)
But not all of it needs to run during load shedding. (We're in South Africa so its normal to have no power for 2 hours a day)
Can we say, pull 75a from the inverter (pv, batteries etc) and an additional 50a from Eskom (grid), using the passthrough ability, to supply a total of 125a?
Thanks for any feedback.

The challenge you will have is that if you rely on the passthrough current of 200A (per phase continuous) using a recommended breaker size of 240A as long as you do not loose the grid, eg. a load shedding event) as the maximum power that the inverter can provide per phase is approx 80A (depending on the PF) or 1.5 time this rating for 10 seconds.
The answer to your question, can you pull a total of 125A (per phase). You can as long as you do not loose the grid.
My suggestion is that you supply non essential loads from the Grid and only connect the essential loads to the rating of the inverter or you parallel 2 * 50kW inverters.
