Greetings and thanks for any info you can provide…
I have seen the “Blue Power” video : DON’T WASTE YOUR SOLAR - Enable AC-OUT-2 based on BATTERY SOC [UPDATED 2024] @https://www.youtube.com/watch?v=sAIRQqOspuo and understand how the process works but myself and another are wondering how should the wiring go when our HW is already hooked up to our main breaker panel. Do we run a new line to main panel or can we run it directly to the HW heater? What prevents black flow of power back to the main breaker??? I would like to use this option but unclear on how the wiring should go.
Thanks,
Larry
This is what I have done ,I have wired my water heater with two separate a.c. Inputs my top element is wired on the grid with a timer to prevent using the grid at high grid rates , the lower element is wired from ac 2 output from inverters , remember you must disconnect wires from top heating element to lower heating element from factory water heater ,there is a switching device from the factory , as it powers only one element at a time ,it powers lower element first to heat whole tank ,and when it can’t supply hot water it switches off lower element and heats just top of the tank to supply hot water faster , I have lower element on solar to heat whole tank and save the most .you can google wiring schematic of water heaters with dual heating elements , if you have one element in your tank you will need a power transfer switch to select either grid or solar power , I’ve done this for my well pump
Hey @Gettin_There
you need to disconnect your hotwater from the main distribution panel and connect to AC_out_2 including breakers and RCBO.
AC_out_2 has a relais that can be controlled by a Relais assistant or maybe by NodeRed.
I have split my main distribution panel into two. Left side is connected to AC_out_1, middle is connected to AC_out_2. Both have way switches to either connect to MP2 AC_ou or directly to grid (“Netz”).
