Very strange, wonder if hrowatt in theory infinite wisdom has multiple grounds on some older models
Growatt support just saw my video and got back with me. Apparently the 3000tl lvm 48p doesn't have a gn bond by design. Maybe the es is the same?Very strange, wonder if hrowatt in theory infinite wisdom has multiple grounds on some older models

A breakers job is to protect the wire.
There's no requirement for enough power ahead of it.
That would depend on the wire size used. The breakers job is to protect the wire.
But since 30a is your feed. There's no reason to go above that.
You can use a 30a and 10 awg wire.
Or a 20a and 12 awg wire.
It really doesn't matter. As long as the wire matches the breaker. You are already limited to 30a total by the main breaker.So since main breaker is a 30 still use a double 30 for the dryer in the sub panel. The growatt part is where I am a bit confused again, I think you said 40 amp for pass-through and charging but was thinking a double for was way to big and thought maybe the double 20 would be better, all of my thinking got my confused.

Tim, i have cheaper version of this breaker, do you think i can wire dc in from the bottom and dc out to inverter from the top?I use 2 pole MCB's.

Not recommended. Because it's designed to break the highest flow of current from the top terminals.Tim, i have cheaper version of this breaker, do you think i can wire dc in from the bottom and dc out to inverter from the top?
Really appreciate your every post, Tim. Thank you.Not recommended. Because it's designed to break the highest flow of current from the top terminals.
But if you do, reverse the polarity. This gives you the best chance of being able to open the circuit with less Hazzard.

No separate ground rods.
Only one grounding system for everything.
If your system isn't bonded, you'll always read strange voltages on ground. Because you have the system floating.
The proper way is the jumper from input neutral to output neutral.
