Mat have finally found the issue. When I did the upgrade of the transformers, I bought a new sub panel to use as a distribution panel. I did not know that the panel had a slight bend in the middle behind the busbar. When a heavy load would come on the panel would flex causing one or both...

I have and it went into shutdown as there were too many volts. It got to 600v and shutdown. I'm thinking of disconnecting the transformers and just run the neutral bond instead to see if the transformers are causing the overloads. I have two 5kw transformers wired in now. It goes ac to...

That is what the inverters are reporting. It's causing massive overheating issues.

Nope

I'm set at 60hz

By the shine app and by the inverter telling me it is using 0% of load capacity. Next time it does it I'll share a screenshot of the app

I am having a serious issue with my two growatts. I started having overheating on a transformer 2 months ago and replaced with the Growatt ATS 5000 auto transformer (×2). When in AC bypass they will show 0 watts and over 6k volts! If I'm in sbu I'm fine. If the batteries have to charge on ac,I'm...

Do you run one on each inverter if ran in series?

Are you running an auyo transformer for your Neutral? Either way, go ahead and bond your grounds to Neutral. DISCLAIMER!!!! I AM NOT AN ELECTRICIAN. I AM MOT A CERTIFIED SOLAR TECHNICIAN. ANY AND ALL INFORMATION I GIVE IS AT READERS OWN RISK.

So I've hooked up everything and finally flipped the switch. Running 2 inverters in parallel. One inverter reads the 1st string properly. The other inverter is showing the pv array and only shows 2v. When I cut the 2nd string breaker off I get 224v. I get the 2v reading on both sides of the...

Thank you. Finally someone who made it simple. I am running 2 in parallel with an auto transformer. I haven't installed yet but plan on doing most of the wiring this week before I do the final connections to the main panel. Just going to run my heat pump, water heater and fridge on it until I...

I have another question about the ac input, do I run the neutral from the main supply to the input or is it ground, line 1 and line 2??
