Thanks. Getting a clamp meter to measure inrush current is a good place to start. I started looking at the EG4 6000 after watching one of Will's videos where he said that the this EG4 inverters will start well pumps. Perhaps I would need more than of the inverters in parallel to start my well...

Thanks for reading and responding. Under $10,000 for phase 1. I think I have the skill to do just about anything in this area that is being described in YouTube videos and the manufacturer's owner's manuals. I started this journey thinking I was going to build my own powerwall from the cells...

Yes. I'm definitely looking for all-in-one inverters that can be connected in parallel. The EG4 6000 can be paralled up to 9 units for a 54 Kw system.

Does your daughter have a deep well pump that the Growatt can start and run?

I'm new and trying to learn. Why is there a separate transfer switch in the above diagram? Don't the solar aio units such as the EG4 have built-in transfer switches so that the sub panel could be directly connected to the AC output of the EG4 inverter?

@OffGridInTheCity I'm still learning and trying to figure these things out. What is the purpose of the MTS in your setup? Wouldn't you be able to accomplish the same thing by connecting your panel to the MTS and the inverter to the MTS? With that setup, wouldn't you be able to choose individual...

Thanks. @Mattb4 created two different diagrams in this discussion. The first diagram was for a whole house setup. The later diagram was for a critical loads subpanel setup. I'm trying to understand in what situations one setup make more sense than the other.

@Mattb4 In what situations does it make sense to use the whole home setup that you diagrammed above using the transfer switch vs when does it make sense to use the critical load setup that you diagrammed later, down below, in this discussion?

Thank you. I will add this to my list of components to consider.

Thanks. No panic here on doing a power audit. That is a good idea. It should be fun. I already have The Energy Detective that monitors 16 circuits in my house. I also have a Kill-A-Watt. As @MichaelK suggested, I will get a clamp meter to measure inrush and I'll be off to the races to do my...

Hello all, I'm trying to develop a game plan to install a solar/battery backup system at our house. Below is an outline of my current thinking. Do you have any advice to help me along? I want to create an expandable system that I can add on to as my budget allows. I don't want the system to be...

I'm doing research to possibly install the EG4 18Kpv at my house. In looking at the Whole Home Backup using a Feeder Tap wiring diagram in the 18Kpv user manual, I'm wondering, does it make sense to use a SPAN smart panel as the main breaker panel? I'm assuming SPAN panels include a 200 amp...
