Multiplus 2 night time power saving

Having two 5000w multis wired togeher . Is it possable to have a set up where one could be programed to turn off at set times at night and back on again in the morning, I'm trying to cut down on the standby usage the two multis are drawing at night. At the moment the house standby loads including both Multis are using 2000w over a 12hr peroid. With a battery pack of 10Kw, having to use 2Kw each night is significant.

No, this can't be done with 2 units in parallel. I'm running 2 x 3kW multis. The only way to cut down the overnight power is to use the AES function.

Yes the overnight consumption of the inverters is a problem that most system designers neglect to include when sizing the battery system. 2kWh overnight translates to about 3.5A @48V, which for 10kW of inverter is not too bad.
