I have a question about “pass-through” on my two 24/3000 Multiplus(s)
I haven’t delved into this feature too much, and what I have read/seen, its still a vague concept to me.
My setup at home is 5kW of Solar PVs(LG), 3 Victron MPPT’s (150/100 & 250/100), feeding into a series of Lynx busbars to two Multiplus 24/3000, running in split phase, to a separate sub panel, charging and powered from 60 kWh of LFP batteries (SOK).
I have been slowly adding more and more loads to the subpanel, and it virtually powers anything substantial in my home. My weekly consumption is about 150 kWh on the subpanel, with about 40 kWh still being power from the grid on my main panel. I have not added any high current loads such as the Dryer or Stove (yet), but routinely run my pool pump and air conditioner off the subpanel (solar/battery)
I understand the concept that, if I was in a boat or trailer, connected to “shore” power, and the shore power was limited, to say 20 or 30 amps, and if I tried to run loads that exceeded the capacity of the shore power, the Multiplus(s) would ’supplement’ the power requirement from the battery bank. (Correct?)
What about the opposite? If I ran my stove off my subpanel (~5000W), one leg drawing about 3000W, and my Multiplus was already supply 1000W to the ’normal’ loads, so now it needs to supply 4000W, would it draw power from the grid to make up the difference? (The 24/3000 Multiplus will nominally supply only 2400W).
Both Multiplus(s) are connected to AC power from the main panel, but told to “ignore” AC until my batteries fall to less than 20% SOC.
