Thanks for asking but I think I will save my questions for a different post. In fact, while waiting for a reply from SS I have found many options to consider that answer my questions here on this forum. What I really needed was some reassurance since I'm not gifted in the electrical or solar arts.

I've purchased 26 panels, 4 inventers, and 6 batteries, etc. and I can never get any help from them. The one time I got help was a year ago on the phone. Be prepared to wait. Their email support is useless. They will key in on one thing and bail on the whole email. Buying from them is easy...

What is the status of the balance problem? It would be really nice to know work was is in progress?

I had problems with EG4 batteries staying in balance but believe it's been fixed. 6 EG4 48v 100 AH LifePower4 batteries installed in the rack with + - connected at top of buss bar. I moved the neg cable to the bottom of the buss bar and upped the cable to 2 gauge. So far, it's running...

I have two growatt 48v 3K's. That's disappointing they wouldn't protect themselves and shutdown.

How are you overloading the inverter?

Now I have two 3k's running in parallel single phase for 6k total. The two 3K in split phase wouldn't be enough for everything. I need to add more panels. And you can't run 3 units in split phase. Any other option than replacing the 3k's with 5ks'?

I have two 3K growatt's connected in parallel now. They are running 120v. All is working good now. What I'm thinking of doing is adding another system so I can run the 240v circuits. My plan is to have the two 3K's run the 240v and get a new 5K to run the 120v. But I'm not sure if you can...

The battery specs are EG4 Lithium battery 51.2V (48V) 5.12kWh with 100AH internal BMS. I should have said the circuit breaker goes between the batteries and the growatt-inverter

MY Growatt's call for a 100 amp 60 vdc circuit breaker. But I can only find 100 amp 12-48 vdc. Are these ok?

We have winters here. It can be <10f easy at night and <20f for a week. I plan on insulating and finishing out the shed. It's about 12'x10'.

I'm looking at a temperature controller and heating pad? https://www.amazon.com/gp/product/B01HXM5UAC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I can't find a thread on protecting the equipment from freezing. Everything I find is about batteries while charging. I'm planning my next project with the equipment in our shed. Growatt says to keep it above freezing. What direction should I be looking for a solution? Thanks

Again, I'm new to this. But I believe there are better ways to connect the SCC and Inverter to the batteries. I believe the way you have them connected will cause the batteries to become imbalanced. Hopefully, someone will comment on this.

Newbie here. I made this mistake. If you did your wiring again, make sure the lugs, washers and nuts are in the right order. As I found out, a lock washer makes a good resister.
